international! The Free Translation Project is a +way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this 'ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU 'gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU 'gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + +1.1 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU 'gettext'. Other packages have their own ways to +internationalization, predating GNU 'gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU 'gettext' functions. Installers may use special +options at configuration time for changing the default behaviour. The +command: + + ./configure --disable-nls + +will _totally_ disable translation of messages. + + When you already have GNU 'gettext' installed on your system and run +configure without an option for your new package, 'configure' will +probably detect the previously built and installed 'libintl' library and +will decide to use it. If not, you may have to to use the +'--with-libintl-prefix' option to tell 'configure' where to look for it. + + Internationalized packages usually have many 'po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at 'configure' time by using the +'--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable 'LINGUAS' +may be set, prior to configuration, to limit the installed set. +'LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.2 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the 'LANG' environment variable to the appropriate +'LL_CC' combination. If you happen to have the 'LC_ALL' or some other +'LC_xxx' environment variables set, you should unset them before setting +'LANG', otherwise the setting of 'LANG' will not have the desired +effect. Here 'LL' is an ISO 639 two-letter language code, and 'CC' is +an ISO 3166 two-letter country code. For example, let's suppose that +you speak German and live in Germany. At the shell prompt, merely +execute 'setenv LANG de_DE' (in 'csh'), 'export LANG; LANG=de_DE' (in +'sh') or 'export LANG=de_DE' (in 'bash'). This can be done from your +'.login' or '.profile' file, once and for all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, 'de_AT' is used for Austria, and 'pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of 'LL_CC', with 'LL' denoting the +language and 'CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are used, +such as 'LL' or 'LL_CC.ENCODING'. You can get the list of locales +supported by your system for your language by running the command +'locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +'LANGUAGE'. GNU 'gettext' gives preference to 'LANGUAGE' over 'LANG' +for the purpose of message handling, but you still need to have 'LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather read +translations in German than English for when Swedish is not available, +set 'LANGUAGE' to 'sv:de' while leaving 'LANG' to 'sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from 'no' to 'nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under 'nb' and some older ones under 'no', it's recommended +for Norwegian users to set 'LANGUAGE' to 'nb:no' so that both newer and +older translations are used. + + In the 'LANGUAGE' environment variable, but not in the 'LANG' +environment variable, 'LL_CC' combinations can be abbreviated as 'LL' to +denote the language's main dialect. For example, 'de' is equivalent to +'de_DE' (German as spoken in Germany), and 'pt' to 'pt_PT' (Portuguese +as spoken in Portugal) in this context. + +1.3 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +'http://translationproject.org/', in the "Teams" area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +'-request' appended. For example, speakers of Swedish can send a +message to 'sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate _actively_ +in translations, or at solving translational difficulties, rather than +merely lurking around. If your team does not exist yet and you want to +start one, or if you are unsure about what to do or how to get started, +please write to 'coordinator@translationproject.org' to reach the +coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skills are praised more than +programming skills, here. + +1.4 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of Jun 2014. +The matrix shows, in regard of each package, for which languages PO +files have been submitted to translation

Of course you have to respect the GNU Lesser General Public +License which covers the use of the GNU 'gettext' library. This means +in particular that even non-free programs can use 'libintl' as a shared +library, whereas only free software can use 'libintl' as a static +library or use modified versions of 'libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of 'gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +'coordinator@translationproject.org' to make the '.pot' files available +to the translation teams. diff --git a/AUTHORS b/AUTHORS new file mode 100644 index 0000000..d0f0715 --- /dev/null +++ b/AUTHORS @@ -0,0 +1,21 @@ +# -*- mode: rec -*- + +# This file contains the names of the people that contributed with +# code and/or documentation to GNU recutils. + +Name: Jose E.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command './configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the 'README' file for +instructions specific to this package. Some packages provide this +'INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The 'configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a 'Makefile' in each directory of the package. +It may also create one or more '.h' files containing system-dependent +definitions. Finally, it creates a shell script 'config.status' that +you can run in the future to recreate the current configuration, and a +file 'config.log' containing compiler output (useful mainly for +debugging 'configure'). + + It can also use an optional file (typically called 'config.cache' and +enabled with '--cache-file=config.cache' or simply '-C') that saves the +results of its tests to speed up reconfiguring. Caching is disabled by +default to prevent problems with accidental use of stale cache files. + + If you need to do unusual things to compile the package, please try +to figure out how 'configure' could check whether to do them, and mail +diffs or instructions to the address given in the 'README' so they can +be considered for the next release. If you are using the cache, and at +some point 'config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file 'configure.ac' (or 'configure.in') is used to create +'configure' by a program called 'autoconf'. You need 'configure.ac' if +you want to change it or regenerate 'configure' using a newer version of +'autoconf'. + + The simplest way to compile this package is: + + 1. 'cd' to the directory containing the package's source code and type + './configure' to configure the package for your system. + + Running 'configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type 'make' to compile the package. + + 3. Optionally, type 'make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type 'make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the 'make install' phase executed with root + privileges. + + 5. Optionally, type 'make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior 'make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing 'make clean'. To also remove the + files that 'configure' created (so you can compile the package for + a different kind of computer), type 'make distclean'. There is + also a 'make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type 'make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide 'make + distcheck', which can by used by developers to test that all other + targets like 'make install' and 'make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the 'configure' script does not know about. Run './configure --help' +for details on some of the pertinent environment variables. + + You can give 'configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here is +an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU 'make'. 'cd' to the +directory where you want the object files and executables to go and run +the 'configure' script. 'configure' automatically checks for the source +code in the directory that 'configure' is in and in '..'. This is known +as a "VPATH" build. + + With a non-GNU 'make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use 'make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple '-arch' options to the +compiler but only a single '-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the 'lipo' tool if you have problems. + +Installation Names +================== + + By default, 'make install' installs the package's commands under +'/usr/local/bin', include files under '/usr/local/include', etc. You +can specify an installation prefix other than '/usr/local' by giving +'configure' the option '--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option '--exec-prefix=PREFIX' to 'configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like '--bindir=DIR' to specify different values for particular +kinds of files. Run 'configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the default +for these options is expressed in terms of '${prefix}', so that +specifying just '--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to 'configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +'make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, 'make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +'${prefix}'. Any directories that were specified during 'configure', +but not in terms of '${prefix}', must each be overridden at install time +for the entire installation to be relocated. The approach of makefile +variable overrides for each directory variable is required by the GNU +Coding Standards, and ideally causes no recompilation. However, some +platforms have known limitations with the semantics of shared libraries +that end up requiring recompilation when using this method, particularly +noticeable in packages that use GNU Libtool. + + The second method involves providing the 'DESTDIR' variable. For +example, 'make install DESTDIR=/alternate/directory' will prepend +'/alternate/directory' before all installation names. The approach of +'DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of '${prefix}' +at 'configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving 'configure' the +option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. + + Some packages pay attention to '--enable-FEATURE' options to +'configure', where FEATURE indicates an optional part of the package. +They may also pay attention to '--with-PACKAGE' options, where PACKAGE +is something like 'gnu-as' or 'x' (for the X Window System). The +'README' should mention any '--enable-' and '--with-' options that the +package recognizes. + + For packages that use the X Window System, 'configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the 'configure' options '--x-includes=DIR' and +'--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of 'make' will be. For these packages, running './configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with 'make V=1'; while running './configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with 'make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC +is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX 'make' updates targets which have the same timestamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its '' header file. The option '-nodtk' can be used as a +workaround. If GNU CC is not installed, it is therefore recommended to +try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put '/usr/ucb' early in your 'PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in '/usr/bin'. So, if you need '/usr/ucb' +in your 'PATH', put it _after_ '/usr/bin'. + + On Haiku, software installed for all users goes in '/boot/common', +not '/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features 'configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, 'configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +'--build=TYPE' option. TYPE can either be a short name for the system +type, such as 'sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file 'config.sub' for the possible values of each field. If +'config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option '--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with '--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for 'configure' scripts to share, +you can create a site shell script called 'config.site' that gives +default values for variables like 'CC', 'cache_file', and 'prefix'. +'configure' looks for 'PREFIX/share/config.site' if it exists, then +'PREFIX/etc/config.site' if it exists. Or, you can set the +'CONFIG_SITE' environment variable to the location of the site script. +A warning: not all 'configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to 'configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the 'configure' command line, using 'VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified 'gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an +Autoconf limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +'configure' Invocation +====================== + + 'configure' recognizes the following options to control how it +operates. + +'--help' +'-h' + Print a summary of all of the options to 'configure', and exit. + +'--help=short' +'--help=recursive' + Print a summary of the options unique to this package's + 'configure', and exit. The 'short' variant lists options used only + in the top level, while the 'recursive' variant lists options also + present in any nested packages. + +'--version' +'-V' + Print the version of Autoconf used to generate the 'configure' + script, and exit. + +'--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally 'config.cache'. FILE defaults to '/dev/null' to + disable caching. + +'--config-cache' +'-C' + Alias for '--cache-file=config.cache'. + +'--quiet' +'--silent' +'-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to '/dev/null' (any error + messages will still be shown). + +'--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + 'configure' can determine that directory automatically. + +'--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: for + more details, including other options available for fine-tuning the + installation locations. + +'--no-create' +'-n' + Run the configure checks, but stop before creating any output + files. + +'configure' also accepts some other, not widely useful, options. Run +'configure --help' for more details. diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..7a9cf16 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,27 @@ +# Top-level Makefile.am + +# Copyright (C) 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2020, 2022 +# Jose E.

GNU/Hurd build fixed. + . Aggregate functions now work properly in Aarch64 and powerpc. + + Version 1.7 (25 March 2014) +* Utilities: + . rec2csv now supports a -d option to change the delimiter + character in CSV files. + . It is now possible to specify several recfiles in the + command line containing anonymous records. +* Format: + . Support for restricting the fields that can appear in records + with the new %allowed special field. + .

It now possible to jump several records while navigating + using a prefix argument to the next/previous commands. +* Documentation: + . The examples in the manual have been improved, and well as many + other aspects: formatting, English, etc. Special thanks to Karl + Berry for pointing out the problems and suggesting solutions. +* Internal cleanup and code factorization. +* Many, many, many bug fixes :D + + Version 1.6 (03 November 2013) +* Utilities: + . Support for joins and foreign keys. + . Grouping records by one or more fields. + . Sorting recors by several fields. + . Specifying rewrite rules in field expressions. + .

It is the first copyright statement that meets all of the +# following conditions. Subsequent copyright statements are +# ignored. +# 2. Its format is "Copyright (C)", then a list of copyright years, +# and then the name of the copyright holder. +# 3. The "(C)" takes one of the following forms or is omitted +# entirely: +# +# A. (C) +# B. (c) +# C. @copyright{} +# D. © +# E. © +# +# 4. The "Copyright" appears at the beginning of a line, except that it +# may be prefixed by any sequence (e.g., a comment) of no more than +# 5 characters -- including white space. +# 5. Iff such a prefix is present, the same prefix appears at the +# beginning of each remaining line within the FSF copyright +# statement.

The replacement of "*" +# by " " is consistent throughout all subsequent lines. +# 6. Blank lines, even if preceded by the prefix, do not appear +# within the FSF copyright statement. +# 7. Each copyright year is 2 or 4 digits, and years are separated by +# commas, "-", or "--". Whitespace may appear after commas. +# +# Environment variables: +# +# 1. If UPDATE_COPYRIGHT_FORCE=1, a recognized FSF copyright statement +# is reformatted even if it does not need updating for the new +# year. If unset or set to 0, only updated FSF copyright +# statements are reformatted. +# 2. If UPDATE_COPYRIGHT_USE_INTERVALS=1, every series of consecutive +# copyright years (such as 90, 1991, 1992-2007, 2008) in a +# reformatted FSF copyright statement is collapsed to a single +# interval (such as 1990-2008).

+ +Everyone is permitted to copy and distribute verbatim copies +of this license document, but changing it is not allowed. +@end display + +@enumerate 0 +@item +PREAMBLE + +The purpose of this License is to make a manual, textbook, or other +functional and useful document @dfn{free} in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +Secondarily, this License preserves for the author and publisher a way +to get credit for their work, while not being considered responsible +for modifications made by others. + +This License is a kind of ``copyleft'', which means that derivative +works of the document must themselves be free in the same sense. It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + +@item +APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The ``Document'', below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as ``you''. You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A ``Modified Version'' of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A ``Secondary Section'' is a named appendix or a front-matter section +of the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall +subject (or to related matters) and contains nothing that could fall +directly within that overall subject. (Thus, if the Document is in +part a textbook of mathematics, a Secondary Section may not explain +any mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The ``Invariant Sections'' are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The ``Cover Texts'' are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A ``Transparent'' copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not ``Transparent'' is called ``Opaque''. + +Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, La@TeX{} input +format, SGML or XML using a publicly available +DTD, and standard-conforming simple HTML, +PostScript or PDF designed for human modification. Examples +of transparent image formats include PNG, XCF and +JPG. Opaque formats include proprietary formats that can be +read and edited only by proprietary word processors, SGML or +XML for which the DTD and/or processing tools are +not generally available, and the machine-generated HTML, +PostScript or PDF produced by some word processors for +output purposes only. + +The ``Title Page'' means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, ``Title Page'' means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +The ``publisher'' means any person or entity that distributes copies +of the Document to the public. + +A section ``Entitled XYZ'' means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as ``Acknowledgements'', +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' +of such a section when you modify the Document means that it remains a +section ``Entitled XYZ'' according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the ``History'' section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles. Section numbers +or the equivalent are not considered part of the section titles. + +@item +Delete any section Entitled ``Endorsements''. Such a section +may not be included in the Modified Version. + +@item +Do not retitle any existing section to be Entitled ``Endorsements'' or +to conflict in title with any Invariant Section. + +@item +Preserve any Warranty Disclaimers. +@end enumerate + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled ``Endorsements'', provided it contains +nothing but endorsements of your Modified Version by various +parties---for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled ``History'' +in the various original documents, forming one section Entitled +``History''; likewise combine any sections Entitled ``Acknowledgements'', +and any sections Entitled ``Dedications''.

This is +most useful for specifying day of the week items or relative items (see +below). Among the most commonly used ordinal numbers, the word +@samp{last} stands for @math{-1}, @samp{this} stands for 0, and +@samp{first} and @samp{next} both stand for 1. Because the word +@samp{second} stands for the unit of time there is no way to write the +ordinal number 2, but for convenience @samp{third} stands for 3, +@samp{fourth} for 4, @samp{fifth} for 5, +@samp{sixth} for 6, @samp{seventh} for 7, @samp{eighth} for 8, +@samp{ninth} for 9, @samp{tenth} for 10, @samp{eleventh} for 11 and +@samp{twelfth} for 12. + +@cindex months, written-out +When a month is written this way, it is still considered to be written +numerically, instead of being ``spelled in full''; this changes the +allowed strings. + +@cindex language, in dates +In the current implementation, only English is supported for words and +abbreviations like @samp{AM}, @samp{DST}, @samp{EST}, @samp{first}, +@samp{January}, @samp{Sunday}, @samp{tomorrow}, and @samp{year}. + +@cindex language, in dates +@cindex time zone item +The output of the @command{date} command +is not always acceptable as a date string, +not only because of the language problem, but also because there is no +standard meaning for time zone items like @samp{IST}@.

A leading zero must be present +if a number is less than ten. If @var{year} is 68 or smaller, then 2000 +is added to it; otherwise, if @var{year} is less than 100, +then 1900 is added to it. The construct +@samp{@var{month}/@var{day}/@var{year}}, popular in the United States, +is accepted.

Literal months may be abbreviated +to their first three letters, possibly followed by an abbreviating dot. +It is also permitted to write @samp{Sept} instead of @samp{September}. + +When months are written literally, the calendar date may be given as any +of the following: + +@example +@var{day} @var{month} @var{year} +@var{day} @var{month} +@var{month} @var{day} @var{year} +@var{day}-@var{month}-@var{year} +@end example + +Or, omitting the year: + +@example +@var{month} @var{day} +@end example + + +@node Time of day items +@section Time of day items + +@cindex time of day item + +A @dfn{time of day item} in date strings specifies the time on a given +day.

In this notation, 12 is the predecessor of 1: +midnight is @samp{12am} while noon is @samp{12pm}. +(This is the zero-oriented interpretation of @samp{12am} and @samp{12pm}, +as opposed to the old tradition derived from Latin +which uses @samp{12m} for noon and @samp{12pm} for midnight.) + +@cindex time zone correction +@cindex minutes, time zone correction by +The time may alternatively be followed by a time zone correction, +expressed as @samp{@var{s}@var{hh}@var{mm}}, where @var{s} is @samp{+} +or @samp{-}, @var{hh} is a number of zone hours and @var{mm} is a number +of zone minutes. +The zone minutes term, @var{mm}, may be omitted, in which case +the one- or two-digit correction is interpreted as a number of hours. +You can also separate @var{hh} from @var{mm} with a colon. +When a time zone correction is given this way, it +forces interpretation of the time relative to +Coordinated Universal Time (UTC), overriding any previous +specification for the time zone or the local time zone. For example, +@samp{+0530} and @samp{+05:30} both stand for the time zone 5.5 hours +ahead of UTC (e.g., India). +This is the best way to +specify a time zone correction by fractional parts of an hour. +The maximum zone correction is 24 hours. + +Either @samp{am}/@samp{pm} or a time zone correction may be specified, +but not both. + + +@node Time zone items +@section Time zone items + +@cindex time zone item + +A @dfn{time zone item} specifies an international time zone, indicated +by a small set of letters, e.g., @samp{UTC} or @samp{Z} +for Coordinated Universal +Time. Any included periods are ignored. By following a +non-daylight-saving time zone by the string @samp{DST} in a separate +word (that is, separated by some white space), the corresponding +daylight saving time zone may be specified. +Alternatively, a non-daylight-saving time zone can be followed by a +time zone correction, to add the two values. This is normally done +only for @samp{UTC}; for example, @samp{UTC+05:30} is equivalent to +@samp{+05:30}. + +Time zone items other than @samp{UTC} and @samp{Z} +are obsolescent and are not recommended, because they +are ambiguous; for example, @samp{EST} has a different meaning in +Australia than in the United States, and @samp{A} has different +meaning as a military time zone than as an obsolescent +RFC 822 time zone. Instead, it's better to use +unambiguous numeric time zone corrections like @samp{-0500}, as +described in the previous section. + +If neither a time zone item nor a time zone correction is supplied, +timestamps are interpreted using the rules of the default time zone +(@pxref{Specifying time zone rules}). + + +@node Combined date and time of day items +@section Combined date and time of day items + +@cindex combined date and time of day item +@cindex ISO 8601 date and time of day format +@cindex date and time of day format, ISO 8601 + +The ISO 8601 date and time of day extended format consists of an ISO +8601 date, a @samp{T} character separator, and an ISO 8601 time of +day.

These are fuzzy +units, as years and months are not all of equal duration. More precise +units are @samp{fortnight} which is worth 14 days, @samp{week} worth 7 +days, @samp{day} worth 24 hours, @samp{hour} worth 60 minutes, +@samp{minute} or @samp{min} worth 60 seconds, and @samp{second} or +@samp{sec} worth one second. An @samp{s} suffix on these units is +accepted and ignored. + +@findex ago @r{in date strings} +The unit of time may be preceded by a multiplier, given as an optionally +signed number. Unsigned numbers are taken as positively signed. No +number at all implies 1 for a multiplier.

They may be used to stress other +items, like in @samp{12:00 today}. The string @samp{this} also has +the meaning of a zero-valued time displacement, but is preferred in +date strings like @samp{this thursday}. + +When a relative item causes the resulting date to cross a boundary +where the clocks were adjusted, typically for daylight saving time, +the resulting date and time are adjusted accordingly. + +The fuzz in units can cause problems with relative items. For +example, @samp{2020-07-31 -1 month} might evaluate to 2020-07-01, +because 2020-06-31 is an invalid date. To determine the previous +month more reliably, you can ask for the month before the 15th of the +current month. For example: + +@example +$ date -R +Thu, 31 Jul 2020 13:02:39 -0400 +$ date --date='-1 month' +'Last month was %B?' +Last month was July? +$ date --date="$(date +%Y-%m-15) -1 month" +'Last month was %B!' +Last month was June! +@end example + +Also, take care when manipulating dates around clock changes such as +daylight saving leaps. In a few cases these have added or subtracted +as much as 24 hours from the clock, so it is often wise to adopt +universal time by setting the @env{TZ} environment variable to +@samp{UTC0} before embarking on calendrical calculations. + +@node Pure numbers in date strings +@section Pure numbers in date strings + +@cindex pure numbers in date strings + +The precise interpretation of a pure decimal number depends +on the context in the date string. + +If the decimal number is of the form @var{yyyy}@var{mm}@var{dd} and no +other calendar date item (@pxref{Calendar date items}) appears before it +in the date string, then @var{yyyy} is read as the year, @var{mm} as the +month number and @var{dd} as the day of the month, for the specified +calendar date. + +If the decimal number is of the form @var{hh}@var{mm} and no other time +of day item appears before it in the date string, then @var{hh} is read +as the hour of the day and @var{mm} as the minute of the hour, for the +specified time of day. @var{mm} can also be omitted. + +If both a calendar date and a time of day appear to the left of a number +in the date string, but no relative item, then the number overrides the +year. + + +@node Seconds since the Epoch +@section Seconds since the Epoch + +If you precede a number with @samp{@@}, it represents an internal +timestamp as a count of seconds. The number can contain an internal +decimal point (either @samp{.} or @samp{,}); any excess precision not +supported by the internal representation is truncated toward minus +infinity. Such a number cannot be combined with any other date +item, as it specifies a complete timestamp. + +@cindex beginning of time, for POSIX +@cindex Epoch, for POSIX +Internally, computer times are represented as a count of seconds since +an Epoch---a well-defined point of time. On GNU and +POSIX systems, the Epoch is 1970-01-01 00:00:00 UTC, so +@samp{@@0} represents this time, @samp{@@1} represents 1970-01-01 +00:00:01 UTC, and so forth. GNU and most other +POSIX-compliant systems support such times as an extension +to POSIX, using negative counts, so that @samp{@@-1} +represents 1969-12-31 23:59:59 UTC. + +Most modern systems count seconds with 64-bit two's-complement integers +of seconds with nanosecond subcounts, which is a range that includes +the known lifetime of the universe with nanosecond resolution. +Some obsolescent systems count seconds with 32-bit two's-complement +integers and can represent times from 1901-12-13 20:45:52 through +2038-01-19 03:14:07 UTC@. A few systems sport other time ranges. + +@cindex leap seconds +On most hosts, these counts ignore the presence of leap seconds. +For example, on most hosts @samp{@@1483228799} represents 2016-12-31 +23:59:59 UTC, @samp{@@1483228800} represents 2017-01-01 00:00:00 +UTC, and there is no way to represent the intervening leap second +2016-12-31 23:59:60 UTC. + +@node Specifying time zone rules +@section Specifying time zone rules + +@vindex TZ +Normally, dates are interpreted using the rules of the current time +zone, which in turn are specified by the @env{TZ} environment +variable, or by a system default if @env{TZ} is not set. To specify a +different set of default time zone rules that apply just to one date, +start the date with a string of the form @samp{TZ="@var{rule}"}. The +two quote characters (@samp{"}) must be present in the date, and any +quotes or backslashes within @var{rule} must be escaped by a +backslash. + +For example, with the GNU @command{date} command you can +answer the question ``What time is it in New York when a Paris clock +shows 6:30am on October 31, 2019?'' by using a date beginning with +@samp{TZ="Europe/Paris"} as shown in the following shell transcript: + +@example +$ export TZ="America/New_York" +$ date --date='TZ="Europe/Paris" 2019-10-31 06:30' +Sun Oct 31 01:30:00 EDT 2019 +@end example + +In this example, the @option{--date} operand begins with its own +@env{TZ} setting, so the rest of that operand is processed according +to @samp{Europe/Paris} rules, treating the string @samp{2019-10-31 +06:30} as if it were in Paris. However, since the output of the +@command{date} command is processed according to the overall time zone +rules, it uses New York time. (Paris was normally six hours ahead of +New York in 2019, but this example refers to a brief Halloween period +when the gap was five hours.) + +A @env{TZ} value is a rule that typically names a location in the +@uref{https://www.iana.org/time-zones, @samp{tz} database}. +A recent catalog of location names appears in the +@uref{https://twiki.org/cgi-bin/xtra/tzdatepick.html, TWiki Date and Time +Gateway}. A few non-GNU hosts require a colon before a +location name in a @env{TZ} setting, e.g., +@samp{TZ=":America/New_York"}. + +The @samp{tz} database includes a wide variety of locations ranging +from @samp{Arctic/Longyearbyen} to @samp{Antarctica/South_Pole}, but +if you are at sea and have your own private time zone, or if you are +using a non-GNU host that does not support the @samp{tz} +database, you may need to use a POSIX rule instead. Simple +POSIX rules like @samp{UTC0} specify a time zone without +daylight saving time; other rules can specify simple daylight saving +regimes. @xref{TZ Variable,, Specifying the Time Zone with @code{TZ}, +libc, The GNU C Library}. + +@node Authors of parse_datetime +@section Authors of @code{parse_datetime} +@c the anchor keeps the old node name, to try to avoid breaking links +@anchor{Authors of get_date} + +@cindex authors of @code{parse_datetime} + +@cindex Bellovin, Steven M. +@cindex Salz, Rich +@cindex Berets, Jim +@cindex MacKenzie, David +@cindex Meyering, Jim +@cindex Eggert, Paul +@code{parse_datetime} started life as @code{getdate}, as originally +implemented by Steven M.

Top + +1 Introduction +************** + +* Menu: + +* Purpose:: Why recutils. +* A Little Example:: Recutils in action. + + +File: recutils.info, Node: Purpose, Next: A Little Example, Up: Introduction + +1.1 Purpose +=========== + +GNU recutils is a set of tools and libraries to access human-editable, +text-based databases called _recfiles_. The data is stored as a +sequence of records, each record containing an arbitrary number of named +fields. Advanced capabilities usually found in other data storage +systems are supported: data types, data integrity (keys, mandatory +fields, etc.) as well as the ability of records to refer to other +records (sort of foreign keys). Despite its simplicity, recfiles can be +used to store medium-sized databases. + + So, yet another data storage system? The mere existence of this +package deserves an explanation. There is a rich set of already +available free data storage systems, covering a broad range of +requirements. Big systems having complex data storage requirements will +probably make use of some full-fledged relational system such as MySQL +or PostgreSQL. Less demanding applications, or applications with +special deployment requirements, may find it more convenient to use a +simpler system such as SQLite, where the data is stored in a single +binary file. XML files are often used to store configuration settings +for programs, and to encode data for transmission through networks. + + So it looks like all the needs are covered by the existing solutions +... but consider the following characteristics of the data storage +systems mentioned in the previous paragraph: + + - The stored data is not directly human readable. + - The stored data is definitely not directly writable by humans. + - They are program dependent. + - They are not easily managed by version control systems. + + Regarding the first point (human readability), while it is clearly +true for the binary files, some may argue XML files are indeed human +readable... well... '<bar><foo tag="val">try</foo> to r&iamp;ead +<p>this</p></bar>'. YAML (1) is an example of a hierarchical data +storage format which is much more readable than XML. The problem with +YAML is that it was designed as a "data serialization language" and thus +to map the data constructs usually found in programming languages. That +makes it too complex for the simple task of storing plain lists of +items. + + Recfiles are human-readable, human-writable and still easy to parse +and to manipulate automatically. Obviously they are not suitable for +any task (for example, it can be difficult to manage hierarchies in +recfiles) and performance is somewhat sacrificed in favor of +readability. But they are quite handy to store small to medium simple +databases. + + The GNU recutils suite comprises: + + - This Texinfo manual, describing the Rec format and the accompanying + software. + - A C library (librec) that provides a rich set of functions to + manipulate rec data. + - A set utilities that can be used in shell scripts and in the + command line to operate on rec files. + - An emacs mode, 'rec-mode'. + + ---------- Footnotes ---------- + + (1) Yet Another Markup Language + + +File: recutils.info, Node: A Little Example, Prev: Purpose, Up: Introduction + +1.2 A Little Example +==================== + +Everyone loves to grow a nice book collection at home. Unfortunately, +in most cases the management of our private books gets uncontrolled: +some books get lost, some of them may be loaned to some friend, there +are some duplicated (or even triplicated!) titles because we forgot +about the existence of the previous copy, and many more details. + + In order to improve the management of our little book collection we +could make use of a complex data storage system such as a relational +database. The problem with that approach, as explained in the previous +section, is that the tool is too complicated for the simple task: we do +not need the full power of a relational database system to maintain a +simple collection of books. + + With GNU recutils it is possible to maintain such a little database +in a text file. Let's call it 'books.rec'. The following table resumes +the information items that we want to store for each title, along with +some common-sense restrictions. + + - Every book has a title, even if it is "No Title". + - A book can have several titles. + - A book can have more than one author. + - For some books the author is not known. + - Sometimes we don't care about who the author of a book is. + - We usually store our books at home. + - Sometimes we loan books to friends. + - On occasions we lose track of the physical location of a book. Did + we loan it to anyone? Was it lost in the last move? Is it in some + hidden place at home? + +The contents of the rec file follows: + + # -*- mode: rec -*- + + %rec: Book + %mandatory: Title + %type: Location enum loaned home unknown + %doc: + + A book in my personal collection. + + Title: GNU Emacs Manual + Author: Richard M. Stallman + Publisher: FSF + Location: home + + Title: The Colour of Magic + Author: Terry Pratchett + Location: loaned + + Title: Mio Cid + Author: Anonymous + Location: home + + Title: chapters.gnu.org administration guide + Author: Nacho Gonzalez + Author: Jose E. Marchesi + Location: unknown + + Title: Yeelong User Manual + Location: home + + # End of books.rec + + Simple. The file contains a set of records separated by blank lines. +Each record comprises a set of fields with a name and a value. + + The GNU recutils can then be used to access the contents of the file. +For example, we could get a list of the names of loaned books by +invoking 'recsel' in the following way: + + $ recsel -e "Location = 'loaned'" -P Title books.rec + The Colour of Magic + + +File: recutils.info, Node: The Rec Format, Next: Querying Recfiles, Prev: Introduction, Up: Top + +2 The Rec Format +**************** + +A recfile is nothing but a text file which conforms to a few simple +rules. This chapter shows you how, by observing these rules, recfiles +of arbitrary complexity can be written. + +* Menu: + +* Fields:: The key-value pairs which comprise the data. +* Records:: The main entities of a recfile. +* Comments:: Information for humans' benefit only. +* Record Descriptors:: Describing different types of records. + + +File: recutils.info, Node: Fields, Next: Records, Up: The Rec Format + +2.1 Fields +========== + +A "field" is the written form of an association between a label and a +value. For example, if we wanted to associate the label 'Name' with the +value 'Ada Lovelace' we would write: + + Name: Ada Lovelace + + The separator between the field name and the field value is a colon +followed by a blank character (space and tabs, but not newlines). The +name of the field shall begin in the first column of the line. + + A "field name" is a sequence of alphanumeric characters plus +underscores ('_'), starting with a letter or the character '%'. The +regular expression denoting a field name is: + + [a-zA-Z%][a-zA-Z0-9_]* + + Field names are case-sensitive. 'Foo' and 'foo' are different field +names. + + The following list contains valid field names (the final colon is not +part of the names): + + Foo: + foo: + A23: + ab1: + A_Field: + + The "value of a field" is a sequence of characters terminated by a +single newline character ('\n'). + + Sometimes a value is too long to fit in the usual width of terminals +and screens. In that case, depending on the specific tool used to +access the file, the readability of the data would not be that good. It +is therefore possible to physically split a logical line by escaping a +newline with a backslash character, as in: + + LongLine: This is a quite long value \ + comprising a single unique logical line \ + split in several physical lines. + + The sequence '\n' (newline) '+' (PLUS) and an optional '_' (SPACE) is +interpreted as a newline when found in a field value. For example, the +C string '"bar1\nbar2\n bar3"' would be encoded in the following way in +a field value: + + Foo: bar1 + + bar2 + + bar3 + + +File: recutils.info, Node: Records, Next: Comments, Prev: Fields, Up: The Rec Format + +2.2 Records +=========== + +A "record" is a group of one or more fields written one after the other: + + Name1: Value1 + Name2: Value2 + Name2: Value3 + + It is possible for several fields in a record to share the same name +or/and the field value. The following is a valid record containing +three fields: + + Name: John Smith + Email: john.smith@foomail.com + Email: john@smith.name + + The "size of a record" is defined as the number of fields that it +contains. A record cannot be empty, so the minimum size for a record is +1. The maximum number of fields for a record is only limited by the +available physical resources. The size of the previous record is 3. + + Records are separated by one or more blank lines. For instance, the +following example shows a file named 'personalities.rec' featuring three +records: + + Name: Ada Lovelace + Age: 36 + + Name: Peter the Great + Age: 53 + + Name: Matusalem + Age: 969 + + +File: recutils.info, Node: Comments, Next: Record Descriptors, Prev: Records, Up: The Rec Format + +2.3 Comments +============ + +Any line having an '#' (ASCII 0x23) character in the first column is a +comment line. + + Comments may be used to insert information that is not part of the +database but useful in other ways. They are completely ignored by +processing tools and can only be seen by looking at the recfile itself. + + It is also quite convenient to comment-out information from the +recfile without having to remove it in a definitive way: you may want to +recover the data into the database later! Comment lines can be used to +comment-out both full registers and single fields: + + Name: Jose E. Marchesi + # Occupation: Software Engineer + # Severe lack of brain capacity + # Fired on 02/01/2009 (without compensation) + Occupation: Unoccupied + + Comments are also useful for headers, footers, comment blocks and all +kind of markers: + + # -*- mode: rec -*- + # + # TODO + # + # This file contains the Bugs database of GNU recutils. + # + # Blah blah... + + ... + + # End of TODO + + Unlike some file formats, comments in recfiles must be complete +lines. You cannot start a comment in the middle of a line. For +example, in the following record, the '#' does _not_ start a comment: + Name: Peter the Great # Russian Tsar + Age: 53 + + +File: recutils.info, Node: Record Descriptors, Prev: Comments, Up: The Rec Format + +2.4 Record Descriptors +====================== + +Certain properties of a set of records can be specified by preceding +them with a "record descriptor". A record descriptor is itself a +record, and uses fields with some predefined names to store properties. + +* Menu: + +* Record Sets:: Defining different types of records. +* Naming Record Types:: Some conventions on naming record sets. +* Documenting Records:: Documenting your record sets. +* Record Sets Properties:: Introducing the special fields. + + +File: recutils.info, Node: Record Sets, Next: Naming Record Types, Up: Record Descriptors + +2.4.1 Record Sets +----------------- + +The most basic property that can be specified for a set of records is +their "type". The special field name '%rec' is used for that purpose: + + %rec: Entry + + Id: 1 + Name: Entry 1 + + Id: 2 + Name: Entry 2 + + The records following the descriptors are then identified as having +its type. So in the example above we would say there are two records of +type "Entry". Or in a more colloquial way we would say there are two +"Entries" in the database. + + The effect of a record descriptor ends when another descriptor is +found in the stream of records. This allows you to store different +kinds of records in the same database. For example, suppose you are +maintaining a depot. You will need to keep track of both what items are +available and when they are sold or restocked. + + The following example shows the usage of two record descriptors to +store both kind of records: articles and stock. + + %rec: Article + + Id: 1 + Title: Article 1 + + Id: 2 + Title: Article 2 + + %rec: Stock + + Id: 1 + Type: sell + Date: 20 April 2011 + + Id: 2 + Type: stock + Date: 21 April 2011 + + The collection of records having same types in recfiles are known as +"record sets" in recutils jargon. In the example above two record sets +are defined: one containing articles and the other containing stock +movements. + + Nothing prevents having empty record sets in databases. This is in +fact usually the case when a new recfile is written but no data exists +yet. In our depot example we could write a first version of the +database containing just the record descriptors: + + %rec: Article + + %rec: Stock + + Special records are not required, and many recfiles do not have them. +This is because all the records contained in the file are of the same +type, and their nature can usually be inferred from both the file name +and their contents. For example, 'contacts.rec' could simply contain +records representing contacts without an explicit '%rec: Contact' record +descriptor. In this case we say that the type of the anonymous records +stored in the file is the "default record type". + + Another possible situation, although not usual, is to have a recfile +containing both non-typed (default) and typed record types: + + Id: 1 + Title: Blah + + Id: 2 + Title: Bleh + + %rec: Movement + + Date: 13-Aug-2012 + Concept: 20 + + Date: 24-Sept-2012 + Concept: 12 + +In this case the records preceding the movements are of the "default" +type, whereas the records following the record descriptor are of type +'Movement'. Even though it is supported by the format and the +utilities, it is generally not recommended to mix non-typed and typed +records in a recfile. + + +File: recutils.info, Node: Naming Record Types, Next: Documenting Records, Prev: Record Sets, Up: Record Descriptors + +2.4.2 Naming Record Types +------------------------- + +It is up to you how to name your record sets. Any string comprising +only alphanumeric characters or underscores, and that starts with a +letter will be a legal name. However, it is recommended to use the +singular form of a noun in order to describe the "type" of the records +in the records set. Examples are 'Article', 'Contributor', 'Employee' +and 'Movement'. + + The used noun should be specific enough in order to characterize the +property of the records which matters. For example, in a contributor's +database it would be better to have a record set named 'Contributor' +than 'Person'. + + The reason of using singular nouns instead of their plural forms is +that it works better with the utilities: it is more natural to read +'recsel -t Contributor' ('-t' is for "type") than 'recsel -t +Contributors'. + + +File: recutils.info, Node: Documenting Records, Next: Record Sets Properties, Prev: Naming Record Types, Up: Record Descriptors + +2.4.3 Documenting Records +------------------------- + +As well as a name, it is a good idea to provide a description of the +record set. This is sometimes called the record set's "documentation" +and is specified using the '%doc' field. + + Whereas the name is usually short and can contain only alphanumeric +characters and underscores, no such restriction applies to the +documentation. The documentation is typically more verbose than the +name provided by the '%rec' field and may contain arbitrary characters +such as punctuation and parentheses. It is somewhat similar to a +comment (*note Comments::), but it can be managed more easily in a +programmatic way. Unlike a comment, the '%doc' field is recognized by +tools such as 'recinf' (*note Invoking recinf::) which processes record +descriptors. For example, you might have two record sets with '%rec' +and '%doc' fields as follows: + + %rec: Contact + %doc: Family, friends and acquaintances (other than business). + + Name: Granny + Phone: +12 23456677 + + Name: Edwina + Phone: +55 0923 8765 + + + %rec: Associate + %doc: Colleagues and other business contacts + + Name: Karl Schmidt + Phone: +49 88234566 + + Name: Genevieve Curie + Phone: +33 34 87 65 + + +File: recutils.info, Node: Record Sets Properties, Prev: Documenting Records, Up: Record Descriptors + +2.4.4 Record Sets Properties +---------------------------- + +Besides determining the type of record that follows in the stream, +record descriptors can be used to describe other properties of those +records. This can be done by using "special fields", which have special +names from a predefined set. Consider for example the following +database, where record descriptors are used to specify a (optional) +numeric 'Id' and a mandatory 'Title' field: + + %rec: Item + %type: Id int + %mandatory: Title + + Id: 10 + Title: Notebook (big) + + Id: 11 + Title: Fountain Pen + + Note that the names of special fields always start with the character +'%'. Also note that it is also possible to use non-special fields in a +record descriptor, but such fields will have no effect on the described +record set. + + Every record set must contain one, and only one, field named '%rec'. +It is not mandated that that field must occupy the first position in the +record. However, it is considered a good style to place it as the first +field in the record set, in order for the casual reader to easily +identify the type of the records. + + The following list briefly describes the special fields defined in +the recutils format, along with references to the sections of this +manual describing their usage in depth. + +'%rec' + Naming record types. Also, they allow using external and remote + descriptors. *Note Remote Descriptors::. +'%mandatory, %allowed and %prohibit' + Requiring or forbidding specific fields. *Note Mandatory Fields::. + *Note Prohibited Fields::. *Note Allowed Fields::. +'%unique and %key' + Working with keys. *Note Keys and Unique Fields::. +'%doc' + Documenting your database. *Note Documenting Records::. +'%typedef and %type' + Field types. *Note Field Types::. +'%auto' + Auto-counters and time-stamps. *Note Auto-Generated Fields::. +'%sort' + Keeping your record sets sorted. *Note Sorted Output::. +'%size' + Restricting the size of your database. *Note Size Constraints::. +'%constraint' + Enforcing arbitrary constraints. *Note Arbitrary Constraints::. +'%confidential' + Storing confidential information. *Note Encryption::. +'%singular' + Fields without repeating values. + + +File: recutils.info, Node: Querying Recfiles, Next: Editing Records, Prev: The Rec Format, Up: Top + +3 Querying Recfiles +******************* + +Since recfiles are always human readable, you could lookup data simply +by opening an editor and searching for the desired information. Or you +could use a standard tool such as 'grep' to extract strings matching a +pattern. However, recutils provides a more powerful and flexible way to +lookup data. The following sections explore how the recutils can be +used in order to extract data from recfiles, from very basic and simple +queries to quite complex examples. + +* Menu: + +* Simple Selections:: Introducing 'recsel'. +* Selecting by Type:: Get the records of some given type. +* Selecting by Position:: Get the record occupying some position. +* Random Records:: Get a set of random records. +* Selection Expressions:: Get the records satisfying some expression. +* Field Expressions:: Selecting a subset of fields. +* Sorted Output:: Get the records in a given order. + + +File: recutils.info, Node: Simple Selections, Next: Selecting by Type, Up: Querying Recfiles + +3.1 Simple Selections +===================== + +'recsel' is an utility whose primary purpose is to select records from a +recfile and print them on standard output. Consider the following +example record set, which we shall assume is saved in a recfile called +'acquaintances.rec': + + # This database contains a list of both real and fictional people + # along with their age. + + Name: Ada Lovelace + Age: 36 + + Name: Peter the Great + Age: 53 + + # Name: Matusalem + # Age: 969 + + Name: Bart Simpson + Age: 10 + + Name: Adrian Mole + Age: 13.75 + +If we invoke 'recsel acquaintances.rec' we will get a list of all the +records stored in the file in the terminal: + + $ recsel acquaintances.rec + Name: Ada Lovelace + Age: 36 + + Name: Peter the Great + Age: 53 + + Name: Bart Simpson + Age: 10 + + Name: Adrian Mole + Age: 13.75 + +Note that the commented out parts of the file, in this case the +explanatory header and the record corresponding to Matusalem, are not +part of the output produced by 'recsel'. This is because 'recsel' is +concerned only with the data. + + 'recsel' will also "pack" the records so any extra empty lines that +may be between records are not echoed in the output: + + *acquaintances.rec:* $ recsel acquaintances.rec + Name: Peter the Great + Name: Peter the Great Age: 53 + Age: 53 + Name: Bart Simpson + # Note the extra empty lines. Age: 10 + + + Name: Bart Simpson + Age: 10 + +It is common to store data gathered in several recfiles. For example, +we could have a 'contacts.rec' file containing general contact records, +and also a 'work-contacts.rec' file containing business contacts: + + *contacts.rec:* *work-contacts.rec:* + + Name: Granny Name: Yoyodyne Corp. + Phone: +12 23456677 Email: sales@yoyod.com + Phone: +98 43434433 + Name: Doctor + Phone: +12 58999222 Name: Robert Harris + Email: robert.harris@yoyod.com + Note: Sales Department. + + Both files can be passed to 'recsel' in the command line. In that +case 'recsel' will simply process them and output their records in the +same order they were specified: + + $ recsel contacts.rec work-contacts.rec + Name: Granny + Phone: +12 23456677 + + Name: Doctor + Phone: +12 58999222 + + Name: Yoyodyne Corp. + Email: sales@yoyod.com + Phone: +98 43434433 + + Name: Robert Harris + Email: robert.harris@yoyod.com + Note: Sales Department. + +As mentioned above, the output follows the ordering on the command line, +so 'recsel work-contacts.rec contacts.rec' would output the records of +'work-contacts.rec' first and then the ones from 'contacts.rec'. + +Note however that 'recsel' will merge records from several files +specified in the command line only if they are anonymous. If the +contacts in our files were typed: + + *contacts.rec:* *work-contacts.rec:* + + %rec: Contact %rec: Contact + + Name: Granny Name: Yoyodyne Corp. + Phone: +12 23456677 Email: sales@yoyod.com + Phone: +98 43434433 + Name: Doctor + Phone: +12 58999222 Name: Robert Harris + Email: robert.harris@yoyod.com + Note: Sales Department. + +Then we would get the following error message: + + $ recsel contacts.rec work-contacts.rec + recsel: error: duplicated record set 'Contact' from work-contacts.rec. + + +File: recutils.info, Node: Selecting by Type, Next: Selecting by Position, Prev: Simple Selections, Up: Querying Recfiles + +3.2 Selecting by Type +===================== + +As we saw in the section discussing record descriptors, it is possible +to have several different types of records in a single recfile. +Consider for example a 'gnu.rec' file containing information about +maintainers and packages in the GNU Project: + + %rec: Maintainer + + Name: Jose E. Marchesi + Email: jemarch@gnu.org + + Name: Luca Saiu + Email: positron@gnu.org + + %rec: Package + + Name: GNU recutils + LastRelease: 12 February 2014 + + Name: GNU epsilon + LastRelease: 10 March 2013 + +If 'recsel' is invoked in that file it will complain: + + $ recsel gnu.rec + recsel: error: several record types found. Please use -t to specify one. + +This is because 'recsel' does not know which records to output: the +maintainers or the packages. This can be resolved by using the '-t' +command line option: + + $ recsel -t Package gnu.rec + Name: GNU recutils + LastRelease: 12 February 2014 + + Name: GNU epsilon + LastRelease: 10 March 2013 + +By default 'recsel' never outputs record descriptors. This is because +most of the time the user is only interested in the data. However, with +the '-d' command line option, the record descriptor of the selected type +is printed preceding the data records: + + $ recsel -d -t Maintainer gnu.rec + %rec: Maintainer + + Name: Jose E. Marchesi + Email: jemarch@gnu.org + + Name: Luca Saiu + Email: positron@gnu.org + +Note that at the moment it is not possible to select non-typed (default) +records when other record sets are stored in the same file. This is one +of the reasons why mixing non-typed records and typed records in a +single recfile is not recommended. + +Note also that if a nonexistent record type is specified in '-t' then +'recsel' does nothing. + + +File: recutils.info, Node: Selecting by Position, Next: Random Records, Prev: Selecting by Type, Up: Querying Recfiles + +3.3 Selecting by Position +========================= + +As was explained in the previous sections, 'recsel' outputs all the +records of some record set. The records are echoed in the same order +they are written in the recfile. However, often it is desirable to +select a subset of the records, determined by the position they occupy +in their record set. + + The '-n' command line option to 'recsel' supports doing this in a +natural way. This is how we would retrieve the first contact listed in +a contacts database using 'recsel': + + $ recsel -n 0 contacts.rec + Name: Granny + Phone: +12 23456677 + +Note that the index is zero-based. If we want to retrieve more records +we can specify several indexes to '-n' separated by commas. If a given +index is too big, it is simply ignored: + + $ recsel -n 0,1,999 contacts.rec + Name: Granny + Phone: +12 23456677 + + Name: Doctor + Phone: +12 58999222 + +With '-n', the order in which the records are echoed does not depend on +the order of the indexes passed to '-n'. For example, the output of +'recsel -n 0,1' will be identical to the output of 'recsel -n 1,0'. + + Ranges of indexes can also be used to select a subset of the records. +For example, the following call would also select the first three +contacts of the database: + + $ recsel -n 0-2 contacts.rec + Name: Granny + Phone: +12 23456677 + + Name: Doctor + Phone: +12 58999222 + + Name: Dad + Phone: +12 88229900 + +It is possible to mix single indexes and index ranges in the same call. +For example, 'recsel -n 0,5-6' would select the first, sixth and seventh +records. + + +File: recutils.info, Node: Random Records, Next: Selection Expressions, Prev: Selecting by Position, Up: Querying Recfiles + +3.4 Random Records +================== + +Consider a database in which each record is a cooking recipe. It is +always difficult to decide what to cook each day, so it would be nice if +we could ask 'recsel' to pick up a random recipe. This can be achieved +using the '-m' ('--random') command line option of 'recsel': + + $ recsel -m 1 recipes.rec + Title: Curry chicken + Ingredient: A whole chicken + Ingredient: Curry + Preparation: ... + +If we need two recipes, because we will be cooking at both lunch and +dinner, we can pass a different number to '-m': + + $ recsel -m 2 recipes.rec + Title: Fabada Asturiana + Ingredient: 300 gr of fabes. + Ingredient: Chorizo + Ingredient: Morcilla + Preparation: ... + + Title: Pasta with ragu + Ingredient: 500 gr of spaghetti. + Ingredient: 2 tomatoes. + Ingredient: Minced meat. + Preparation: ... + +The algorithm used to implement '-m' guarantees that you will never get +multiple instances of the same record. This means that if a record set +has N records and you ask for N random records, you will get all the +records in a random order. + + +File: recutils.info, Node: Selection Expressions, Next: Field Expressions, Prev: Random Records, Up: Querying Recfiles + +3.5 Selection Expressions +========================= + +"Selection expressions", also known as "sexes" in recutils jargon, are +infix expressions that can be applied to a record. A "sex" is a +predicate which selects a subset of records within a recfile. They can +be simple expressions involving just one operator and a pair of +operands, or complex compound expressions with parenthetical +sub-expressions and many operators and operands. One of their most +common uses is to examine records matching a particular set of +conditions. + +* Menu: + +* Selecting by predicate:: Selecting records which satisfy conditions. +* SEX Operands:: Literal values, fields and sub-expressions. +* SEX Operators:: Arithmetic, logical and other operators. +* SEX Evaluation:: Selection expressions are like generators. + + +File: recutils.info, Node: Selecting by predicate, Next: SEX Operands, Up: Selection Expressions + +3.5.1 Selecting by predicate +---------------------------- + +Consider the example recfile 'acquaintances.rec' introduced earlier. It +contains names of people along with their respective ages. Suppose we +want to get a list of the names of all the children. It would not be +easy to do this using 'grep'. Neither would it, for any reasonably +large recfile, be feasible to search manually for the children. +Fortunately the 'recsel' command provides an easy way to do such a +lookup: + $ recsel -e "Age < 18" -P Name acquaintances.rec + Bart Simpson + Adrian Mole + +Let us look at each of the arguments to 'recsel' in turn. Firstly we +have '-e' which tells 'recsel' to lookup records matching the expression +'Age < 18' -- in other words all those people whose ages are less than +18. This is an example of a "selection expression". In this case it is +a simple test, but it can be as complex as needed. + + Next, there is '-P' which tells 'recsel' to print out the value of +the 'Name' field -- because we want just the name, not the entire +record. The final argument is the name of the file from whence the +records are to come: 'acquaintances.rec'. + + Rather than explicitly storing ages in the recfile, a more realistic +example might have the date of birth instead (otherwise it would be +necessary to update the people's ages in the recfile on every birthday). + + # Date of Birth + %type: Dob date + + Name: Alfred Nebel + Dob: 20 April 2010 + Email: alf@example.com + + Name: Bertram Worcester + Dob: 3 January 1966 + Email: bert@example.com + + Name: Charles Spencer + Dob: 4 July 1997 + Email: charlie@example.com + + Name: Dirk Hogart + Dob: 29 June 1945 + Email: dirk@example.com + + Name: Ernest Wright + Dob: 26 April 1978 + Email: ernie@example.com + +Now we can achieve a similar result as before, by looking up the names +of all those people who were born after a particular date: + $ recfix acquaintances.rec + $ recsel -e "Dob >> '31 July 1994'" -p Name acquaintances.rec + Name: Alfred Nebel + Name: Charles Spencer + +The '>>' operator means "later than", and is used here to select a date +of birth after 31st July 1994. Note also that this example uses a lower +case '-p' whereas the preceding example used the upper case '-P'. The +difference is that '-p' prints the field name and field value, whereas +'-P' prints just the value. + + 'recsel' accepts more than one '-e' argument, each introducing a +selection expression, in which case the records which satisfy all +expressions are selected. You can provide more than one field label to +'-P' or '-p' in order to select additional fields to be displayed. For +example, if you wanted to send an email to all children 14 to 18 years +of age, and today's date were 1st August 2012, then you could use the +following command to get the name and email address of all such +children: + + $ recfix acquaintances.rec + $ recsel -e "Dob >> '31 July 1994' && Dob << '01 August 1998'" \ + -p Name,Email acquaintances.rec + Name: Charles Spencer + Email: charlie@example.com + +As you can see, there is only one such child in our record set. + + Note that the example command shown above contains both double quotes +'"' and single quotes '''. The double quotes are interpreted by the +shell (e.g. 'bash') and the single quotes are interpreted by 'recsel', +defining a string. (And the backslash is interpreted by the shell, the +usual continuation character so that this manual doesn't have a too-long +line.) + + +File: recutils.info, Node: SEX Operands, Next: SEX Operators, Prev: Selecting by predicate, Up: Selection Expressions + +3.5.2 SEX Operands +------------------ + +The supported operands are: numbers, strings, field names and +parenthesized expressions. + +3.5.2.1 Numeric Literals +........................ + +The supported numeric literals are integer numbers and real numbers. +The usual sign character '-' is used to denote negative values. Integer +values can be denoted in base 10, base 16 using the '0x' prefix, and +base 8 using the '0' prefix. Examples are: + + 10000 + 0 + 0xFF + -0xa + 012 + -07 + -1342 + .12 + -3.14 + +3.5.2.2 String Literals +....................... + +String values are delimited by either the ''' character or the '"' +character. Whichever delimiter is used, the delimiter closing the +literal must be the same as the delimiter used to open it. + + Newlines and tabs can be part of a string literal. + + Examples are: + + 'Hello.' + 'The following example is the empty string.' + '' + + The ''' and '"' characters can be part of a string if they are +escaped with a backslash, as in: + + 'This string contains an apostrophe: \'.' + "This one a double quote: \"." + +3.5.2.3 Field Values +.................... + +The value of a field value can be included in a selection expression by +writing its name. The field name is replaced by a string containing the +field value, to handle the possibility of records with more than one +field by that name. Examples: + + Name + Email + long_field_name + + It is possible to use the role part of a field if it is not empty. +So, for example, if we are searching for the issues opened by 'John +Smith' in a database of issues we could write: + + $ recsel -e "OpenedBy = 'John Smith'" + +instead of using a full field name: + + $ recsel -e "Hacker:Name:OpenedBy = 'John Smith'" + + When the name of a field appears in an expression, the expression is +applied to all the fields in the record featuring that name. So, for +example, the expression: + + Email ~ "\\.org" + +matches any record in which there is a field named 'Email' whose value +terminates in (the literal string) '.org'. If we are interested in the +value of some specific email, we can specify its relative position in +the containing record by using "subscripts". Consider, for example: + + Email[0] ~ "\\.org" + +Will match for: + + Name: Mr. Foo + Email: foo@foo.org + Email: mr.foo@foo.com + +But not for: + + Name: Mr. Foo + Email: mr.foo@foo.com + Email: foo@foo.org + + The regexp syntax supported in selection expressions is POSIX EREs, +with several GNU extensions. *Note Regular Expressions::. + +3.5.2.4 Parenthesized Expressions +................................. + +Parenthesis characters ('(' and ')') can be used to group sub +expressions in the usual way. + + +File: recutils.info, Node: SEX Operators, Next: SEX Evaluation, Prev: SEX Operands, Up: Selection Expressions + +3.5.3 Operators +--------------- + +The supported operators are arithmetic operators (addition, subtraction, +multiplication, division and modulus), logical operators, string +operators and field operators. + +3.5.3.1 Arithmetic Operators +............................ + +Arithmetic operators for addition ('+'), subtraction ('-'), +multiplication ('*'), integer division ('/') and modulus ('%') are +supported with their usual meanings. + + These operators require either numeric operands or string operands +whose value can be interpreted as numbers (integer or real). + +3.5.3.2 Boolean Operators +......................... + +The boolean operators *and* ('&&'), *or* ('||') and *not* ('!') are +supported with the same semantics as their C counterparts. + + A compound boolean operator '=>' is also supported in order to ease +the elaboration of constraints in records: 'A => B', which can be read +as "A implies B", translates into '!A || (A && B)'. + + The boolean operators expect integer operands, and will try to +convert any string operand to an integer value. + +3.5.3.3 Comparison Operators +............................ + +The compare operators *less than* ('<'), *greater than* ('>'), *less +than or equal* ('<='), *greater than or equal* ('>='), *equal* ('=') and +*unequal* ('!=') are supported with their usual meaning. + + Strings can be compared with the equality operator ('='). + + The match operator ('~') can be used to match a string with a given +regular expression (*note Regular Expressions::). + +3.5.3.4 Date Comparison Operators +................................. + +The compare operators *before* ('<<'), *after* ('>>') and *same time* +('==') can be used with fields and strings containing parseable dates. + + *Note Date input formats::. + +3.5.3.5 Field Operators +....................... + +Field counters are replaced by the number of occurrences of a field with +the given name in the record. For example: + + #Email + + The previous expression is replaced with the number of fields named +'Email' in the record. It can be zero if the record does not have a +field with that name. + +3.5.3.6 String Operators +........................ + +The string concatenation operator ('&') can be used to concatenate any +number of strings and field values. + + 'foo' & Name & 'bar' + +3.5.3.7 Conditional Operator +............................ + +The ternary conditional operator can be used to select alternatives +based on the value of some expression: + + expr1 ? expr2 : expr3 + + If 'expr1' evaluates to true (i.e. it is an integer or the string +representation of an integer and its value is not zero) then the +operator yields 'expr2'. Otherwise it yields 'expr3'. + + +File: recutils.info, Node: SEX Evaluation, Prev: SEX Operators, Up: Selection Expressions + +3.5.4 Evaluation of Selection Expressions +----------------------------------------- + +Given that: + + - It is possible to refer to fields by name in selection expressions. + - Records can have several fields with the same name. + +It is clear that some backtracking mechanism is needed in the evaluation +of the selection expressions. For example, consider the following +expression that is deciding whether a "registration" in a webpage should +be rejected: + + ((Email ~ "foomail\.com") || (Age <= 18)) && !#Fixed + + The previous expression will be evaluated for every possible +permutation of the fields "Email", "Age" and "Fixed" present in the +record, until one of the combinations succeeds. At that point the +computation is interrupted. + + When used to decide whether a record matches some criteria, the goal +of a selection expression is to act as a boolean expression. In that +case the final value of the expression depends on both the type and the +value of the result launched by the top-most subexpression: + + - If the result is an integer, the expression is true if its value is + not zero. + - If the result is a real, or a string, the expression evaluates to + false. + + Sometimes a selection expression is used to compute a result instead +of a boolean. In that case the returned value is converted to a string. +This is used when replacing the slots in templates (*note Templates::). + + +File: recutils.info, Node: Field Expressions, Next: Sorted Output, Prev: Selection Expressions, Up: Querying Recfiles + +3.6 Field Expressions +===================== + +"Field expressions" (also known as "fexes") are a way to select fields +of a record. They also allow you to do certain transformations on the +selected fields, such as changing their names. + + A FEX comprises a sequence of "elements" separated by commas: + + ELEM_1,ELEM_2,...,ELEM_N + + Each element makes a reference to one or more fields in a record +identified by a given name and an optional subscript: + + FIELD_NAME[MIN-MAX] + +MIN and MAX are zero-based indexes. It is possible to refer to a field +occupying a given position. For example, consider the following record: + + Name: Mr. Foo + Email: foo@foo.com + Email: foo@foo.org + Email: mr.foo@foo.org + +We would select all the emails of the record with: + + Email + +The first email with: + + Email[0] + +The third email with: + + Email[2] + +The second and the third email with: + + Email[1-2] + + And so on. It is possible to select the same field (or range of +fields) more than once just by repeating them in a field expression. +Thus, the field expression: + + Email[0],Name,Email + +will print the first email, the name, and then all the email fields +including the first one. + + It is possible to include a "rewrite rule" in an element of a field +expression, which specifies an alias for the selected fields: + + FIELD_NAME[MIN-MAX]:ALIAS + +For example, the following field expression specifies an alias for the +fields named 'Email' in a record: + + Name,Email:ElectronicMail + + Since the rewrite rules only affect the fields selected in a single +element of the field expression, it is possible to define different +aliases to several fields having the same name but occupying different +positions: + + Name,Email[0]:PrimaryEmail,Email[1]:SecondaryEmail + +When that field expression is applied to the following record: + + Name: Mr. Foo + Email: primary@email.com + Email: secondary@email.com + Email: other@email.com + +the result will be: + + Name: Mr. Foo + PrimaryEmail: primary@email.com + SecondaryEmail: secondary@email.com + Email: other@email.com + + It is possible to use the dot notation in order to refer to field and +sub-fields. This is mainly used in the context of joins, where new +fields are created having compound names such as 'Foo_Bar'. A reference +to such a field can be done in the fex using dot notation as follows: + + Foo.Bar + + +File: recutils.info, Node: Sorted Output, Prev: Field Expressions, Up: Querying Recfiles + +3.7 Sorted Output +================= + +This special field sets sorting criteria for the records contained in a +record set. Its usage is: + + %sort: FIELD1 FIELD2 ... + +Meaning that the desired order for the records will be determined by the +contents of the fields named in the '%sort' value. The sorting is +always done in ascending order, and there may be records that lack the +involved fields, i.e. the sorting fields need not be mandatory. + + It is an error to have more than one '%sort' field in the same record +descriptor, as only one field list can be used as sorting criteria. + + Consider for example that we want to keep the records in our +inventory system ordered by entry date. We could achieve that by using +the following record descriptor in the database: + + %rec: Item + %type: Date date + %sort: Date + + Id: 1 + Title: Staplers + Date: 10 February 2011 + + Id: 2 + Title: Ruler Pack 20 + Date: 2 March 2009 + + ... + +As you can see in the example above, the fact we use '%sort' in a +database does not mean that the database will be always physically +ordered. Unsorted record sets are not a data integrity problem, and +thus the diagnosis tools must not declare a recfile as +invalid because +of this. The utility 'recfix' provides a way +to physically order the +fields in the file (*note Invoking recfix::). + + On the other hand any program listing, presenting or processing data +extracted from the recfile must honor the '%sort' entry. For example, +when using the following 'recsel' program in the database above we would +get the output sorted by date: + + $ recsel inventory.rec + Id: 2 + Title: Ruler Pack 20 + Date: 2 March 2009 + + Id: 1 + Title: Staplers + Date: 10 February 2011 + +The sorting of the selected field depends on its type: + + - Numeric fields (integers, ranges, reals) are numerically ordered. + - Boolean fields are ordered considering that "false" values come + first. + - Dates are ordered chronologically. + - Any other kind of field is ordered using a lexicographic order. + + It is possible to specify several fields as the sorting criteria. In +that case the records are sorted using a lexicographic order. Consider +for example the following unsorted database containing marks for several +students: + + %rec: Marks + %type: Class enum A B C + %type: Score real + + Name: Mr. One + Class: C + Score: 6.8 + + Name: Mr. Two + Class: A + Score: 6.8 + + Name: Mr. Three + Class: B + Score: 9.2 + + Name: Mr. Four + Class: A + Score: 2.1 + + Name: Mr. Five + Class: C + Score: 4 + +If we wanted to sort it by 'Class' and by 'Score' we would insert a +'%sort' special field in the descriptor, having: + + %rec: Marks + %type: Class enum A B C + %type: Score real + %sort: Class Score + + Name: Mr. Four + Class: A + Score: 2.1 + + Name: Mr. Two + Class: A + Score: 6.8 + + Name: Mr. Three + Class: B + Score: 9.2 + + Name: Mr. Five + Class: C + Score: 4 + + Name: Mr. One + Class: C + Score: 6.8 + +The order of the fields in the '%sort' field is significant.

This is useful for writing shell scripts or when there are +complex data integrity rules stored in the file that we want to be sure +to preserve. + + The following sections discuss the usage of the recutils for altering +recfiles in the level of record: adding new records, deleting or +commenting them out, sorting them, etc. + +* Menu: + +* Inserting Records:: Inserting data into recfiles. +* Deleting Records:: Removing data. +* Sorting Records:: Physical reordering of records. + + +File: recutils.info, Node: Inserting Records, Next: Deleting Records, Up: Editing Records + +4.1 Inserting Records +===================== + +Adding new records to a recfile is pretty trivial: open it with your +text editor and just write down the fields comprising the records. This +is really the best way to add contents to a recfile containing simple +data. However, complex databases may introduce some difficulties: + +_Multi-line values._ + It can be tedious to manually encode the several lines. +_Data integrity._ + It is difficult to manually maintain the integrity of data stored + in the data base. +_Counters and timestamps._ + Some record sets feature auto-generated fields, which are commonly + used to implement counters and time-stamps. *Note Auto-Generated + Fields::. + + Thus, to facilitate the insertion of new data a command line utility +called 'recins' is included in the recutils. The usage of 'recins' is +very simple, and can be used both in the command line or called from +another program. The following subsections discuss several aspects of +using this utility. + +* Menu: + +* Adding Records With recins:: Basics of the 'recins' utility. +* Replacing Records With recins:: Substituting records in a file. +* Adding Anonymous Records:: Inserting or replacing records with no + type. + + +File: recutils.info, Node: Adding Records With recins, Next: Replacing Records With recins, Up: Inserting Records + +4.1.1 Adding Records With recins +-------------------------------- + +Each invocation of 'recins' adds one record to the targeted database. +The fields comprising the records are specified using pairs of '-f' and +'-v' command line arguments. For example, this is how we would add the +first entry to a previously empty contacts database: + + $ recins -f Name -v "Mr Foo" -f Email -v foo@bar.baz contacts.rec + $ cat contacts.rec + Name: Mr. Foo + Email: foo@bar.baz + +If we invoke 'recins' again on the same database we will be adding a +second record: + + $ recins -f Name -v "Mr Bar" -f Email -v bar@gnu.org contacts.rec + $ cat contacts.rec + Name: Mr. Foo + Email: foo@bar.baz + + name: Mr. Bar + Email: bar@gnu.org + + There is no limit on the number of '-f' '-v' pairs that can be +specified to 'recins', other than any limit on command line arguments +which may be imposed by the shell. + + The field values provided using '-v' are encoded to follow the rec +format conventions, including multi-line field values. Consider the +following example: + + $ recins -f Name -v "Mr. Foo" -f Address -v ' + Foostrs. 19 + Frankfurt am Oder + Germany' contacts.rec + $ cat contacts.rec + Name: Mr. Foo + Address: + + Foostrs. 19 + + Frankfurt am Oder + + Germany + + It is also possible to provide fields already encoded as rec data for +their addition, using the '-r' command line argument. This argument can +be intermixed with '-f' '-v'. + + $ recins -f Name -v "Mr. Foo" -r "Email: foo@bar.baz" contacts.rec + $ cat contacts.rec + Name: Mr. Foo + Email: foo@bar.baz + + If the string passed to '-r' is not valid rec data then 'recins' will +complain with an error and the operation will be aborted. + + At this time, it is not possible to add new records containing +comments. + + +File: recutils.info, Node: Replacing Records With recins, Next: Adding Anonymous Records, Prev: Adding Records With recins, Up: Inserting Records + +4.1.2 Replacing Records With recins +----------------------------------- + +'recins' can also be used to replace existing records in a database with +a provided record. This is done by specifying some criteria selecting +the record (or records) to be replaced. + + Consider for example the following command applied to our contacts +database: + + $ recins -e "Email = 'foo@bar.baz'" -f Name -v "Mr. Foo" \ + -f Email -v "new@bar.baz" contacts.rec + +The contact featuring an email 'foo@bar.baz' gets replaced with the +following record: + + Name: Mr. Foo + Email: new@bar.baz + + The records to be replaced can also be specified by index, or a range +of indexes. For example, the following command replaces the first, +second and third records in a database with dummy records: + + $ recins -n 0,1-2 -f Dummy -v XXX foo.rec + $ cat foo.rec + Dummy: XXX + + Dummy: XXX + + Dummy: XXX + + ... Other records ... + + +File: recutils.info, Node: Adding Anonymous Records, Prev: Replacing Records With recins, Up: Inserting Records + +4.1.3 Adding Anonymous Records +------------------------------ + +In a previous chapter we noted that 'recsel' interprets the absence of a +'-t' argument depending on the actual contents of the file. If the +recfile contains records of just one type the command assumes that the +user is referring to these records. + + 'recins' does not follow this convention, and the absence of an +explicit type always means to insert (or replace) an anonymous record. +Consider for example the following database: + + %rec: Marks + %type: Class enum A B C + + Name: Alfred + Class: A + + Name: Bertram + Class: B + +If we want to insert a new mark we have to specify the type explicitly +using '-t': + + $ cat marks.rec | recins -t Marks -f Name -v Xavier -f Class -v C + %rec: Marks + %type: Class enum A B C + + Name: Alfred + Class: A + + Name: Bertram + Class: B + + Name: Xavier + Class: C + +If we forget to specify the type then an anonymous record is created +instead: + + $ cat marks.rec | recins -f Name -v Xavier -f Class -v C + Name: Xavier + Class: C + + %rec: Marks + %type: Class enum A B C + + Name: Alfred + Class: A + + Name: Bertram + Class: B + + +File: recutils.info, Node: Deleting Records, Next: Sorting Records, Prev: Inserting Records, Up: Editing Records + +4.2 Deleting Records +==================== + +Just as 'recins' inserts records, the utility 'recdel' deletes them. +Consider the following recfile 'stock.rec': + %rec: Item + %type: Expiry date + %sort: Title + + Title: First Aid Kit + Expiry: 2 May 2009 + + Title: Emergency Rations + Expiry: 10 August 2009 + + Title: Life raft + Expiry: 2 March 2009 + + Suppose we wanted to delete all items with an 'Expiry' value before a +certain date, we could do this with the following command: + + $ recdel -t Item -e 'Expiry << "5/12/2009"' stock.rec +After running this command, only one record will remain in the file +(viz: the one titled 'Emergency Rations') because all the others have +expiry dates prior to 12 May 2009. (1) The '-t' option can be omitted +if, and only if, there is no '%rec' field in the recfile. + + 'recdel' tries to warn you if you attempt to perform a delete +operation which it deems to be too pervasive. In such cases, it will +refuse to run, unless you give the '--force' flag. However, you should +not rely upon 'recdel' to protect you, because it cannot always +correctly guess that you might be deleting more records than intended. +For this reason, it may be wise to use the '-c' flag, which causes the +relevant records to be commented out, rather than deleted. (And of +course backups are always wise.) + + The complete options available to the 'recdel' command are explained +later. *Note Invoking recdel::. + + ---------- Footnotes ---------- + + (1) '5/12/2009' means the 12th day of May 2009, _not_ the fifth day +of December, even if your 'LC_TIME' environment variable has been set to +suggest otherwise. + + +File: recutils.info, Node: Sorting Records, Prev: Deleting Records, Up: Editing Records + +4.3 Sorting Records +=================== + +In the example above, note the existence of the '%sort: Title' line. +This field was discussed previously (*note Sorted Output::) and, as +mentioned, does not imply that the records need to be stored in the +recfile in any particular order. + + However, if desired, you can automatically arrange the recfile in +that order using 'recfix' with the '--sort' flag. After running the +command + $ recfix --sort stock.rec +the file 'stock.rec' will have its records sorted in alphabetical order +of the 'Title' fields, thus: + %rec: Item + %type: Expiry date + %sort: Title + + Title: Emergency Rations + Expiry: 10 August 2009 + + Title: First Aid Kit + Expiry: 2 May 2009 + + Title: Liferaft + Expiry: 2 March 2009 + + +File: recutils.info, Node: Editing Fields, Next: Field Types, Prev: Editing Records, Up: Top + +5 Editing Fields +**************** + +Fields of a recfile can, of course, be edited manually using an editor +and this is often the easiest way when only a few fields need to be +changed or when the nature of the changes do not follow any particular +pattern. If, however, a large number of similar changes to several +records are required,the 'recset' command can make the job easier. + + The formal description of 'recset' is presented later (*note Invoking +recset::). In this chapter some typical usage examples are discussed. +As with 'recdel', 'recset' if used erroneously has the potential to make +very pervasive changes, which could result in a large loss of data. It +is prudent therefore to take a copy of a recfile before running such +commands. + +* Menu: + +* Adding Fields:: Adding new fields to records. +* Setting Fields:: Editing field values. +* Deleting Fields:: Removing or commenting-out fields. +* Renaming Fields:: Changing the name of a field. + + +File: recutils.info, Node: Adding Fields, Next: Setting Fields, Up: Editing Fields + +5.1 Adding Fields +================= + +As mentioned above, the command 'recins' adds new records to a recfile, +but it cannot add fields to an existing record. This task can be +achieved automatically using 'recset' with its '-a' flag. + + Suppose that (after a stock inspection) you wanted to add an +'Inspected' field to all the items in the recfile. The following +command could be used. + $ recset -t Item -f Inspected -a 'Yes' stock.rec +Here, because no record selection flag was provided, the command +affected _all_ the records of type 'Item'. We could limit the effect of +the command using the '-e', '-q', '-n' or '-m' flags. For example to +add the 'Inspected' field to only the first item the following command +would work: + $ recset -t Item -n 0 -f Inspected -a 'Yes' stock.rec +Similarly, a selection expression could have been used with the '-e' +flag in order to add the field only to records which satisfy the +expression. + + If you use 'recset' with the '-a' flag on a field that already +exists, a new field (in addition to those already present) will be +appended with the given value. + + +File: recutils.info, Node: Setting Fields, Next: Deleting Fields, Prev: Adding Fields, Up: Editing Fields + +5.2 Setting Fields +================== + +It is also possible to update the value of a field. This is done using +'recset' with its '-s' flag. In the previous example, an 'Inspected' +flag was added to certain records, with the value 'yes'. After +reflection, one might want to record the date of inspection, rather than +a simple yes/no flag. Records which have no such field will remain +unchanged. + $ recset -t Item -f Inspected -s '30 October 2006' stock.rec + Although the above command does not have any selection criteria, it +will only affect those records for which a 'Inspected' field exists. +This is because the '-s' flag only sets values of existing fields. It +will not create any fields. + + If instead the '-S' flag is used, this will create the field (if it +does not already exist) _and_ set its value. + $ recset -t Item -f Inspected -S '30 October 2006' stock.rec + + +File: recutils.info, Node: Deleting Fields, Next: Renaming Fields, Prev: Setting Fields, Up: Editing Fields + +5.3 Deleting Fields +=================== + +You can delete fields using 'recset''s '-d' flag. For example, if we +wanted to delete the 'Inspected' field which we introduced above, we +could do so as follows: + $ recset -t Item -f Inspected -d stock.rec +This would delete _all_ fields named 'Inspected' from _all_ records of +type 'Item'. It may be that, we only wanted to delete the 'Inspected' +fields from records which satisfy a certain condition. The following +would delete the fields only from items whose 'Expiry' date was before 2 +January 2010: + $ recset -t Item -e 'Expiry << "2 January 2010"' -f Inspected -d stock.rec + + +File: recutils.info, Node: Renaming Fields, Prev: Deleting Fields, Up: Editing Fields + +5.4 Renaming Fields +=================== + +Another use of 'recset' is to rename existing fields. This is achieved +using the '-r' flag. To rename all instances of the 'Expiry' field +occurring in any record of type 'Item' to 'UseBy', the following command +suffices: + $ recset -t Item -f Expiry -r 'UseBy' stock.rec +As with most operations, this could be done selectively, using the '-e' +flag and a selection expression. + + +File: recutils.info, Node: Field Types, Next: Constraints on Record Sets, Prev: Editing Fields, Up: Top + +6 Field Types +************* + +Field values are, by default, unrestricted text strings. However, it is +often useful to impose some restrictions on the values of certain +fields. For example, consider the following record: + + Id: 111 + Name: Jose E. Marchesi + Age: 30 + MaritalStatus: single + Phone: +49 666 666 66 + + The values of the fields must clearly follow some structure in order +to make sense. 'Id' is a numeric identifier for a person. 'Name' will +never use several lines. 'Age' will typically be in the range '0..120', +and there are only a few valid values for 'MaritalStatus': single, +married, divorced, and widow(er). Phones may be restricted to some +standard format as well to be valid. All these restrictions (and many +others) can be enforced by using "field types". + + There are two kind of field types: "anonymous" and "named". Those +are described in the following subsections. + +* Menu: + +* Declaring Types:: Declaration of types in record descriptors. +* Types and Fields:: Associating fields with types. +* Scalar Field Types:: Numbers and ranges. +* String Field Types:: Lines, limited strings and regular expressions. +* Enumerated Field Types:: Enumerations and boolean values. +* Date and Time Types:: Dates and times. +* Other Field Types:: Emails, fields, UUIDs, ... + + +File: recutils.info, Node: Declaring Types, Next: Types and Fields, Up: Field Types + +6.1 Declaring Types +=================== + +A type can be declared in a record descriptor by using the '%typedef' +special field. The syntax is: + + %typedef: TYPE_NAME TYPE_DESCRIPTION + +Where TYPE_NAME is the name of the new type, and TYPE_DESCRIPTION a +description which varies depending of the kind of type. For example, +this is how a type 'Age_t' could be defined as numbers in the range +'0..120': + + %typedef: Age_t range 0 120 + +Type names are identifiers having the following syntax: + + [a-zA-Z][a-zA-Z0-9_]* + +Even though any identifier with that syntax could be used for types, it +is a good idea to consistently follow some convention to help +distinguishing type names from field names. For example, the '_t' +suffix could be used for types. + + A type can be declared to be an alias for another type. The syntax +is: + + %typedef: TYPE_NAME OTHER_TYPE_NAME + +Where TYPE_NAME is declared to be a synonym of OTHER_TYPE_NAME. This is +useful to avoid duplicated type descriptions. For example, consider the +following example: + + %typedef: Id_t int + %typedef: Item_t Id_t + %typedef: Transaction_t Id_t + +Both 'Item_t' and 'Transaction_t' are aliases for the type 'Id_t'. +Which is in turn an alias for the type 'int'. So, they are both numeric +identifiers. + + The order of the '%typedef' fields is not relevant. In particular, a +type definition can forward-reference another type that is defined +subsequently. The previous example could have been written as: + + %typedef: Item_t Id_t + %typedef: Transaction_t Id_t + %typedef: Id_t int + +Integrity check will complain if undefined types are referenced. As +well as when any aliases up referencing back (looping back directly or +indirectly) in type declarations. For example, the following set of +declarations contains a loop. Thus, it's invalid: + + %typedef: A_t B_t + %typedef: B_t C_t + %typedef: C_t A_t + +The scope of a type is the record descriptor where it is defined. + + +File: recutils.info, Node: Types and Fields, Next: Scalar Field Types, Prev: Declaring Types, Up: Field Types + +6.2 Types and Fields +==================== + +Fields can be declared to have a given type by using the '%type' special +field in a record descriptor. The synopsis is: + + %type: FIELD_LIST TYPE_NAME_OR_DESCRIPTION + +Where FIELD_LIST is a list of field names separated by commas. +TYPE_NAME_OR_DESCRIPTION can be either a type name which has been +previously declared using '%typedef', or a type description. Type names +are useful when several fields are declared to be of the same type: + + %typedef: Id_t int + %type: Id Id_t + %type: Product Id_t + +Anonymous types can be specified by writing a type description instead +of a type name. They help to avoid superfluous type declarations in the +common case where a type is used by just one field. A record containing +a single 'Id' field, for example, can be defined without having to use a +'%typedef' in the following way: + + %rec: Task + %type: Id int + + +File: recutils.info, Node: Scalar Field Types, Next: String Field Types, Prev: Types and Fields, Up: Field Types + +6.3 Scalar Field Types +====================== + +The rec format supports the declaration of fields of the following +scalar types: integer numbers, ranges and real numbers. + + Signed "integers" are supported by using the 'int' declaration: + + %typedef: Id_t int + +Given the declaration above, fields of type 'Id_t' must contain +integers, and they may be negative. Hexadecimal values can be written +using the '0x' prefix, and octal values using an extra '0'. Valid +examples are: + + %type: Id Id_t + + Id: 100 + Id: -23 + Id: -0xFF + Id: 020 + +Sometimes it is desirable to reduce the "range" of integers allowed in a +field. This can be achieved by using a range type declaration: + + %typedef: Interrupt_t range 0 15 + +Note that it is possible to omit the minimum index in ranges. In that +case it is implicitly zero: + + %typedef: Interrupt_t range 15 + +It is possible to use the keywords 'MIN' and 'MAX' instead of a numeral +literal in one or both of the points conforming the range. They mean +the minimum and the maximum integer value supported by the +implementation respectively. See the following examples: + + %typedef: Negative range MIN -1 + %typedef: Positive range 0 MAX + %typedef: AnyInt range MIN MAX + %typedef: Impossible range MAX MIN + +Hexadecimal and octal numbers can be used to specify the limits in a +range. This helps to define scalar types whose natural base is not ten, +like for example: + + %typedef: Address_t range 0x0000 0xFFFF + %typedef: Perms_t range 755 + +"Real" number fields can be declared with the 'real' type specifier. A +wide range of real numbers can be represented this way, only limited by +the underlying floating point representation. The decimal separator is +always the dot ('.') character regardless of the locale setting. For +example: + + %typedef: Longitude_t real + +Examples of fields of type real: + + %rec: Rectangle + %typedef: Longitude_t real + %type: Width Longitude_t + %type: Height Longitude_t + + Width: 25.01 + Height: 10 + + +File: recutils.info, Node: String Field Types, Next: Enumerated Field Types, Prev: Scalar Field Types, Up: Field Types + +6.4 String Field Types +====================== + +The 'line' field type specifier can be used to restrict the value of a +field to a single line, i.e. no newline characters are allowed. For +example, a type for proper names could be declared as: + + %typedef: Name_t line + +Examples of fields of type line: + + Name: Mr. Foo Bar + Name: Mrs. Bar Baz + Name: This is + + invalid + +Sometimes it is the maximum size of the field value that shall be +restricted. The 'size' field type specifier can be used to define the +maximum number of characters a field value can have. For example, if we +were collecting input that will get written in a paper-based forms +system allowing up to 25 characters width entries, we could declare the +entries as: + + %typedef: Address_t size 25 + +Note that hexadecimal and octal integer constants can also be used to +specify field sizes: + + %typedef: Address_t size 0x18 + +Arbitrary restrictions can be defined by using regular expressions. The +"regexp" field type specifier introduces an ERE (extended regular +expression) that will be matched against fields having that name. The +synopsis is: + + %typedef: TYPE_NAME regexp /RE/ + +where RE is the regular expression to match. + + For example, consider the 'Id_t' type designed to represent the +encoding of the identifier of ID cards in some country: + + %typedef: Id_t regexp /[0-9]{9}[a-zA-Z]/ + +Examples of fields of type 'Id_t' are: + + IDCard: 123456789Z + IDCard: invalid id card + +Note that the slashes delimiting the RE can be replaced with any other +character that is not itself used as part of the regexp. That is useful +in some cases such as: + + %typedef: Path_t regexp |(/[^/]/?)+| + +The regexp flavor supported in recfiles are the POSIX EREs plus several +GNU extensions. *Note Regular Expressions::. + + +File: recutils.info, Node: Enumerated Field Types, Next: Date and Time Types, Prev: String Field Types, Up: Field Types + +6.5 Enumerated Field Types +========================== + +Fields of this type contain symbols taken from an enumeration. + + The type is described by writing the sequence of symbols comprising +the enumeration. Enumeration symbols are strings described by the +following regexp: + + [a-zA-Z0-9][a-zA-Z0-9_-]* + +The symbols are separated by blank characters (including newlines). For +example: + + %typedef: Status_t enum NEW STARTED DONE CLOSED + %typedef: Day_t enum Monday Tuesday Wednesday Thursday Friday + + Saturday Sunday + +It is possible to insert comments when describing an enum type. The +comments are delimited by parenthesis pairs. The contents of the +comments can be any character but parentheses. For example: + + %typedef: TaskStatus_t enum + + NEW (The task was just created) + + IN_PROGRESS (Task started) + + CLOSED (Task closed) + +"Boolean" fields, declared with the type specifier 'bool', can be seen +as special enumerations holding the binary values true and false. + + %typedef: Yesno_t bool + +The literals allowed in boolean fields are 'yes/no', '0/1' and +'true/false'. Examples are: + + SwitchedOn: 1 + SwitchedOn: yes + SwitchedOn: false + + +File: recutils.info, Node: Date and Time Types, Next: Other Field Types, Prev: Enumerated Field Types, Up: Field Types + +6.6 Date and Time Types +======================= + +The "date" field type specifier can be used to declare dates and times. +The synopsis is: + + %typedef: TYPE_NAME date + +There are many permitted date formats, described in detail later in this +manual (*note Date input formats::). Of particular note are the +following: + - Dates and times read from recfiles are not affected by the locale + or the timezone. This means that the 'LC_TIME' and the 'TZ' + environment variables are ignored. If you wish, for example, to + specify a time which must be interpreted as UTC, you must + explicitly append the time zone correction: e.g. '2001-1-10 + 12:09Z'. + - The field value '1/10/2001' means January 10, 2001, *not* October + 1, 2001. + - Relative times and dates (such as '1 day ago') are permitted but + are not particularly useful. + + +File: recutils.info, Node: Other Field Types, Prev: Date and Time Types, Up: Field Types + +6.7 Other Field Types +===================== + +The "Email" field type specifier is used to declare electronic +addresses. The synopsis is: + + %typedef: Email_t email + +Sometimes it is useful to make fields to store field names. For that +purpose the "Field" field type specifier is supported. The synopsis is: + + %typedef: Field_t field + +Universally Unique Identifiers (also known as UUIDs) are a way to assign +a globally unique label to some object. The "uuid" field type specifier +serves that purpose. The synopsis is: + + %typedef: Id_t uuid + +The format of the uuids is specified as 32 hexadecimal digits, displayed +in five groups separated by hyphens. For example: + + 550e8400-e29b-41d4-a716-446655440000 + +There is one other possible field type, viz: a foreign key. The +following example defines the type 'Maintainer_t' to be of type "record +'Hacker'"; in other words, a foreign key referring to a record in the +'Hacker' record set. + %typedef: Maintainer_t rec Hacker +This essentially means that the values to be stored in fields of type +'Maintainer_t' are of whatever type is defined for the primary key of +the 'Hacker' record set. Why this is useful is discussed later. *Note +Queries which Join Records::. + + +File: recutils.info, Node: Constraints on Record Sets, Next: Checking Recfiles, Prev: Field Types, Up: Top + +7 Constraints on Record Sets +**************************** + +The records in a recfile are by default not restricted to any particular +structure except that they must contain one or more fields and optional +comments. This provides the format with huge expressive power; but in +many cases, it is also desirable to impose some restrictions in order to +reflect some of the properties of the data stored in the database. It +is also useful in order to preserve data integrity and thus avoid data +corruption. + + The following sections describe the usage of some predefined special +fields whose purpose is to impose this kind of restriction in the +structure of the records. + +* Menu: + +* Mandatory Fields:: Requiring the presence of fields. +* Prohibited Fields:: Forbidding the presence of fields. +* Allowed Fields:: Restricting the presence of fields. +* Keys and Unique Fields:: Fields characterizing records. +* Singular Fields:: Fields with unique contents. +* Size Constraints:: Constraints on the number of records in a set. +* Arbitrary Constraints:: Constraints records must comply with. + + +File: recutils.info, Node: Mandatory Fields, Next: Prohibited Fields, Up: Constraints on Record Sets + +7.1 Mandatory Fields +==================== + +Sometimes, you want to make sure that _every_ record of a particular +type contains certain fields. To do this, use the special field +'%mandatory'. The usage is: + + %mandatory: FIELD1 FIELD2 ... FIELDN +The field names are separated by one or more blank characters. + + The fields listed in a '%mandatory' entry are non-optional; i.e. at +least one field with this name shall be present in any record of this +kind. Records violating this restriction are invalid and a checking +tool will report the situation as a data integrity failure. + + Consider for example an "address book" database where each record +stores the information associated with a contact. The records will be +heterogeneous, in the sense they won't all contain exactly the same +fields: the contact of an Internet shop will probably have a 'URL' +field, while the entry for our grandmother probably won't. We still +want to make sure that every entry has a field with the name of the +contact. In this case, we could use '%mandatory' as follows: + + %rec: Contact + %mandatory: Name + + Name: Granny + Phone: +12 23456677 + + Name: Yoyodyne Corp. + Email: sales@yoyod.com + Phone: +98 43434433 + + A word of caution, however: In many situations, especially in day to +day social interaction, it is common to find that certain information is +simply unavailable. For example, although every person has a date of +birth, some people will refuse to provide that information. + + It is probably wise therefore to avoid stipulating a field as +mandatory, unless it is essential to the enterprise. Otherwise, a data +entry clerk faced with this situation will have to make the choice +between dropping the entry entirely or entering some fake data to keep +the system happy. + + +File: recutils.info, Node: Prohibited Fields, Next: Allowed Fields, Prev: Mandatory Fields, Up: Constraints on Record Sets + +7.2 Prohibited Fields +===================== + +The inverse of '%mandatory' is '%prohibit'. Prohibited fields may not +occur in _any_ record of the given type. The usage is: + + %prohibit: FIELD1 FIELD2 ... FIELDN +The field names are separated by one or more blank characters. + +Fields listed in a '%prohibit' entry are forbidden; i.e. no field with +this name should be present in any record of this kind. Again, records +violating this restriction are invalid. + +Several '%prohibit' fields can appear in the same record descriptor. +The set of prohibited fields is the union of all the entries. For +example, in the following database both 'Id' and 'id' are prohibited: + + %rec: Entry + %prohibit: Id + %prohibit: id + + One possible use case for prohibited fields arises when some field +name is reserved for some future use. For example, if we were +organizing a sports competition, we would want competitors to register +before the event. However a competitor's 'result' should not and cannot +be entered before the competition takes place. Initially then, we would +change the record descriptor as follows: + + %rec: Contact + %mandatory: Name + %prohibit: result +At the start of the event, the '%prohibit' line can be deleted, to allow +results to be entered. + + +File: recutils.info, Node: Allowed Fields, Next: Keys and Unique Fields, Prev: Prohibited Fields, Up: Constraints on Record Sets + +7.3 Allowed Fields +================== + +In some cases we know the set of fields that may appear in the records +of a given type, even if they are not mandatory. The '%allowed' special +field is used to specify this restriction. The usage is: + + %allowed: FIELD1 FIELD2 ... FIELDN +The field names are separated by one or more blank chracters. + +If there are more or one '%allowed' fields in a record descriptor, all +fields of all the records in the record set must be in the union of +'%allowed', '%mandatory' and '%key'. Otherwise an integrity error is +raised. + +Several '%allowed' fields can appear in the same record descriptor. The +set of allowed fields is the union of all the entries. + + +File: recutils.info, Node: Keys and Unique Fields, Next: Singular Fields, Prev: Allowed Fields, Up: Constraints on Record Sets + +7.4 Keys and Unique Fields +========================== + +The '%unique' and '%key' special fields are used to avoid several +instances of the same field in a record, and to implement keys in record +sets. Their usage is: + + %unique: FIELD1 FIELD2 ... FIELDN + %key: FIELD + +The field names are separated by one or more blank characters. + + Normally it is permitted for a record to contain two or more fields +of the same name. The '%unique' special field revokes this +permissiveness. A field declared "unique" cannot appear more than once +in a single record. + + For example, an entry in an address book database could contain an +'Age' field. It does not make sense for a single person to be of +several ages. So, a field could be declared as "unique" in the +corresponding record descriptor as follows: + + %rec: Contact + %mandatory: Name + %unique: Age + +Several '%unique' fields can appear in the same record descriptor. The +set of unique fields is the union of all the entries. + + '%key' makes the referenced field the primary key of the record set. +The primary key behaves as if both '%unique' and '%mandatory' had been +specified for that field. Additionally, there is further restriction, +viz: a given value of a primary key field may appear no more than once +within a record set. + + Consider for example a database of items in stock. Each item is +identified by a numerical 'Id' field. No item may have more than one +'Id', and no items may exist without an associated 'Id'. Additionally, +no two items may share the same 'Id'. This common situation can be +implementing by declaring 'Id' as the key in the record descriptor: + + %rec: Item + %key: Id + %mandatory: Title + + Id: 1 + Title: Box + + Id: 2 + Title: Sticker big + +It would not make sense to have several primary keys in a record set. +Thus, it is not allowed to have several '%key' fields in the same record +descriptor. It is also forbidden for two items to share the same 'Id' +value. Both of these situations would be data integrity violations, and +will be reported by a checking tool. + + Elsewhere, we discuss how primary keys can be used to link one record +set to another using primary keys together with foreign keys. *Note +Queries which Join Records::. + + +File: recutils.info, Node: Singular Fields, Next: Size Constraints, Prev: Keys and Unique Fields, Up: Constraints on Record Sets + +7.5 Singular Fields +=================== + +Sometimes we require certain fields with a given name to not appear in a +record set featuring the same contents, but we don't want (or we can't) +declare such fields as the key of the record set. + + In these circumstances we can use "singular fields", which are +declared as such in the record descriptor using the '%singular' special +field: + + %singular: FIELD + + +File: recutils.info, Node: Size Constraints, Next: Arbitrary Constraints, Prev: Singular Fields, Up: Constraints on Record Sets + +7.6 Size Constraints +==================== + +Sometimes it is desirable to place constraints on entire records. This +can be done with the '%size' special field which is used to limit the +number of records in a record set. Its usage is: + + %size: [RELATIONAL_OPERATOR] NUMBER + +If no operator is specified then NUMBER is interpreted as the exact +number of records of this type. The number can be any integer literal, +including hexadecimal and octal constants. For example: + + %rec: Day + %size: 7 + %type: Name enum + + Monday Tuesday Wednesday Thursday Friday + + Saturday Sunday + %doc: There should be exactly 7 days. + + The optional RELATIONAL_OPERATOR shall be one of '<', '<=', '>' and +'>='. For example: + + %rec: Item + %key: Id + %size: <= 100 + %doc: We have at most 100 different articles. + + It is valid to specify a size of '0', meaning that no records of this +type shall exist in the file. + + Only one '%size' field shall appear in a record descriptor. + + +File: recutils.info, Node: Arbitrary Constraints, Prev: Size Constraints, Up: Constraints on Record Sets + +7.7 Arbitrary Constraints +========================= + +Occasionally, '%mandatory', '%prohibit' and '%size' are just not +flexible enough. We might, for instance, want to ensure that _if_ a +field is present, then it must have a certain relationship to other +fields. Or we might want to stipulate that under certain conditions +only, a record contains a particular field. + + To this end, recutils provides a way for arbitrary field constraints +to be defined. These permit restrictions on the presence and/or value +of fields, based upon the value or presence of other fields within that +record. This is done using the '%constraint' special field. Its usage +is: + + %constraint: EXPR + +where EXPR is a selection expression (*note Selection Expressions::). +When a constraint is present in a record set it means that all the +records of that type must satisfy the selection expression, i.e. the +evaluation of the expression with the record returns 1. Otherwise an +integrity error is raised. + + Consider for example a record type 'Task' featuring two fields of +type date called 'Start' and 'End'. We can use a constraint in the +record set to specify that the task cannot start after it finishes: + + %rec: Task + %type: Start,End date + %constraint: Start << End + + The "implies" operator '=>' is especially useful when defining +constraints, since it can be used to specify conditional constraints, +i.e. constraints applying only in certain records. For example, we +could specify that if a task is closed then it must have an 'End' date +in the following way: + + %rec: Task + %type: Start,End date + %constraint: Start << End + %constraint: Status = 'CLOSED' => #End + + It is acceptable to declare several constraints in the same record +set. + + +File: recutils.info, Node: Checking Recfiles, Next: Remote Descriptors, Prev: Constraints on Record Sets, Up: Top + +8 Checking Recfiles +******************* + +Sometimes, when creating a recfile by hand, typographical errors or +other mistakes will occur. If a recfile contains such mistakes, then +one cannot rely upon the results of queries or other operations. +Fortunately there is a tool called 'recfix' which can find these errors. +It is a good idea to get into the habit of running 'recfix' on a file +after editing it, and before trying other commands. + +* Menu: + +* Syntactical Errors:: Fixing structure errors in recfiles. +* Semantic Errors:: Fixing semantic errors in recfiles. + + +File: recutils.info, Node: Syntactical Errors, Next: Semantic Errors, Up: Checking Recfiles + +8.1 Syntactical Errors +====================== + +One easy mistake is to forget the colon separating the field name from +its value. + + %rec: Article + %key Id + + Name: Thing + Id: 0 +Running 'recfix' on this file will immediately tell us that there is a +problem: + + $ recfix --check inventory.rec + inventory.rec: 2: error: expected a record +Here, 'recfix' has diagnosed a problem in the file 'inventory.rec' and +the problem lies at line 2. If, as in this case, 'recfix' shows there +is a problem with the recfile, you should attend to that problem before +trying to use any other recutils program on that file, otherwise strange +things could happen. The '--check' flag is optional but in normal +execution not required because that is the default operation. + + +File: recutils.info, Node: Semantic Errors, Prev: Syntactical Errors, Up: Checking Recfiles + +8.2 Semantic Errors +=================== + +However 'recfix' checks more than the syntactical integrity of the +recfile. It also checks certain semantics and that the data is +self-consistent. To do this, it uses the special fields of the record, +some of which were introduced above (*note Constraints on Record +Sets::). It is a good idea to use the special fields to stipulate the +"enterprise rules" of the data. + + Errors will be reported if any of the following special keywords are +present and the data does not match the stipulated conditions +'%mandatory' + The mandated fields are missing from a record. +'%prohibit' + The prohibited fields are present in a record. +'%unique' + There is more than one field in a single record of the given name. +'%key' + Two or more records share the same value of the field which is the + key field. +'%typedef and %type' + A field has a value which does not conform to the specified type. +'%size' + The number of records does not conform to the specified + restriction. +'%constraint' + A field does not conform to the specified constraint. +'%confidential' + An unencrypted value exists for a confidential field. + + +File: recutils.info, Node: Remote Descriptors, Next: Grouping and Aggregates, Prev: Checking Recfiles, Up: Top + +9 Remote Descriptors +******************** + +The '%rec' special field is used for two main purposes: to identify a +record as a record descriptor, and to provide a name for the described +record set. The synopsis of the usage of the field is the following: + + %rec: TYPE [URL_OR_FILE] + +TYPE is the name of the kind of records described by the descriptor. It +is mandatory to specify it, and it follows the same lexical conventions +used by field names. *Note Fields::. There is a non-enforced +convention to use singular nouns, because the name makes reference to +the type of a single entity, even if it applies to all the records +contained in the record set. For example, the following record set +contains transactions, and the type specified in the record descriptor +is 'Transaction'. + + %rec: Transaction + + Id: 10 + Title: House rent + + Id: 11 + Title: Loan + +Only one '%rec' field should be in a record descriptor. If there are +more it is an integrity violation. It is highly recommended (but not +enforced) to place this field in the first position of the record +descriptor. + + Sometimes it is convenient to store records of the same type in +different files. The duplication of record descriptors in this case +would surely lead to consistency problems. A possible solution would be +to keep the record descriptor in a separated file and then include it in +any operation by using pipes. For example: + + $ cat descriptor.rec data.rec | recsel ... + +For those cases it is more convenient to use a "external descriptor". +External descriptors can be built appending a file path to the '%rec' +field value, like: + + %rec: FSD_Entry /path/to/file.rec + + The previous example indicates that a record descriptor describing +the 'FSD_Entry' records shall be read from the file '/path/to/file.rec'. +A record descriptor for 'FSD_Entry' may not exist in the external file. +Both relative and absolute paths can be specified there. + + URLs can be used as sources for external descriptors as well. In +that case we talk about "remote descriptors". For example: + + %rec: Department http://www.myorg.com/Org.rec + +The URL shall point to a text file containing rec data. If there is a +record descriptor in the remote file documenting the 'Department' type, +it will be used. + + Note that the local record descriptor can provide additional fields +to "expand" the record type. For example: + + %rec: FSD_Entry http://www.jemarch.net/downloads/FSD.rec + %mandatory: Rating + +The record descriptor above is including the contents of the 'FSD_Entry' +record descriptor from the URL, and adding them to the local record +descriptor, that in this case contains just the '%mandatory' field. + + If you are using GNU recutils (*note Invoking the Utilities::) to +process your recfiles, any URL schema supported by 'libcurl' will work. + + +File: recutils.info, Node: Grouping and Aggregates, Next: Queries which Join Records, Prev: Remote Descriptors, Up: Top + +10 Grouping and Aggregates +************************** + +Grouping and aggregate functions are two related features which are +useful to extract statistics from a record set, or a subset of that +record set. + +* Menu: + +* Grouping Records:: Combining records by fields. +* Aggregate Functions:: Statistics and more. + + +File: recutils.info, Node: Grouping Records, Next: Aggregate Functions, Up: Grouping and Aggregates + +10.1 Grouping Records +===================== + +Consider a recfile containing a list of items in a shop inventory. For +each item it is stored its type, its category, its price, the date of +the last selling operation of an item of that type, and the amount of +items currently available in stock. A sample of such a database could +be: + + Type: EC Car + Category: Toy + Price: 12.2 + LastSell: 20-April-2012 + Available: 623 + + Type: Terria + Category: Food + Price: 0.60 + LastSell: 22-April-2012 + Available: 8239 + + Type: Typex + Category: Office + Price: 1.20 + LastSell: 22-April-2012 + Available: 10878 + + Type: Notebook + Category: Office + Price: 1.00 + LastSell: 21-April-2012 + Available: 77455 + + Type: Sexy Puzzle + Category: Toy + Price: 6.20 + LastSell: 6.20 + Available: 12 + +Now imagine we are interested in grouping the contents of the 'Items' +record set in groups of items of the same category. We can do it using +the '-G' command line argument for 'recsel'. This argument accepts a +list of fields separated by commas. The argument can be read as "group +by". + + In this case we want to group by 'Category', so we would do: + + $ recsel -G Category + Type: Terria + Category: Food + Price: 0.60 + LastSell: 22-April-2012 + Available: 8239 + + Type: Typex + Category: Office + Price: 1.20 + LastSell: 22-April-2012 + Available: 10878 + Type: Notebook + Price: 1.00 + LastSell: 21-April-2012 + Available: 77455 + + Type: EC Car + Category: Toy + Price: 12.2 + LastSell: 20-April-2012 + Available: 623 + Type: Sexy Puzzle + Price: 6.20 + LastSell: 6.20 + Available: 12 + +We can see that the output is three records, corresponding to the three +different categories of items present in the database.

These are so called because +they accept a record set and a field name as inputs and generate a +single result. Usually this result is numerical. + + The supported aggregate functions are the following: + +'Count(FIELD)' + Counts the number of occurrences of a field. +'Avg(FIELD)' + Calculates the average (mean) of the numerical values of a field. +'Sum(FIELD)' + Calculates the sum of the numerical values of a field. +'Min(FIELD)' + Calculates the minimum numerical value of a field. +'Max(FIELD)' + Calculates the maximum numerical value of a field. + + The aggregate functions are to be invoked in the field expressions in +'recsel'. By default they are applied to the totality of the records in +a record set. For example, using the items database from the previous +section, we can do calculations as in the following examples. + + The SQL aggregate functions can be applied to the totality of the +tuples in the relation. For example, using the 'Count' aggregate +function we can calculate the number of fields named 'Category' present +in the record set as follows: + + $ recsel -p "Count(Category)" items.rec + Count_Category: 5 + +The result is a field whose name is derived from the function name and +the field passed as its parameter, separated by an underline. This name +scheme probably suffices for most purposes, but it is always possible to +use a rewrite rule to obtain something different: + + $ recsel -p "Count(Category):NumCategories" items.rec + NumCategories: 5 + +You can use different letter case in writing the name of the aggregate, +and this will be reflected in the field name: + + $ recsel -p "CoUnT(Category)" items.rec + CoUnT_Category: 5 + +It is possible to use more than one aggregate function in the field +expression. Suppose we are also interested in the average price of the +items we sell. We can use the 'Avg' aggregate: + + $ recsel -p "Count(Category),Avg(Price)" items.rec + Count_Category: 5 + Avg_Price: 4.240000 + +Now let's add a field along with an aggregate function to the field +expression and see what we get: + + $ recsel -p "Type,Avg(Price)" items.rec + Type: EC Car + Avg_Price: 12.200000 + + Type: Terria + Avg_Price: 0.600000 + + Type: Typex + Avg_Price: 1.200000 + + Type: Notebook + Avg_Price: 1 + + Type: Sexy Puzzle + Avg_Price: 6.200000 + +We get five records! The reason is that when _only_ aggregate functions +are part of the field expression, they are applied to the single record +that would result from concatenating all the records in the record set +together. However, when a regular field appears in the field expression +the aggregate functions are applied to the individual records. This is +still useful in some cases, such as a database of maintainers: + + Name: Jose E. Marchesi + Email: jemarch@gnu.org + Email: jemarch@es.gnu.org + + Name: Luca Saiu + Email: positron@gnu.org + +Lets see how many emails each maintainer has: + + $ recsel -p "Name,Count(Email)" maintainers.rec + Name: Jose E. Marchesi + Count_Email: 2 + + Name: Luca Saiu + Count_Email: 1 + +Aggregate functions are most useful when we combine them with grouping. +This is when we are interested in some property of a subset of the +records in the database. For example, the average prices of each item +category stored in the database can be obtained by executing: + + $ recsel -p "Category,Avg(Price)" -G Category items.rec + Category: Food + Avg_Price: 0.600000 + + Category: Office + Avg_Price: 1.100000 + + Category: Toy + Avg_Price: 9.200000 + +If we were interested in the actual prices that result in each average +we can do: + + $ recsel -p "Category,Price,Avg(Price)" -G Category items.rec + Category: Food + Price: 0.60 + Avg_Price: 0.600000 + + Category: Office + Price: 1.20 + Price: 1.00 + Avg_Price: 1.100000 + + Category: Toy + Price: 12.2 + Price: 6.20 + Avg_Price: 9.200000 + + +File: recutils.info, Node: Queries which Join Records, Next: Auto-Generated Fields, Prev: Grouping and Aggregates, Up: Top + +11 Queries which Join Records +***************************** + +Suppose you wanted to add the residential address of the people in the +'acquaintances.rec' file from *note Simple Selections::. + + One way to do this is as follows: + %type: Dob date + + Name: Alfred Nebel + Dob: 20 April 2010 + Email: alf@example.com + Address: 42 Abbeter Way, Inprooving, WORCS + Telephone: 01234 5676789 + + Name: Mandy Nebel + Dob: 21 February 1972 + Email: mandy@example.com + Address: 42 Abbeter Way, Inprooving, WORCS + Telephone: 01234 5676789 + + Name: Bertram Nebel + Dob: 3 January 1966 + Email: bert@example.com + Address: 42 Abbeter Way, Inprooving, WORCS + Telephone: 01234 5676789 + + Name: Charles Spencer + Dob: 4 July 1997 + Email: charlie@example.com + Address: 2 Serpe Rise, Little Worning, SURREY + Telephone: 09876 5432109 + + Name: Dirk Spencer + Dob: 29 June 1945 + Email: dirk@example.com + Address: 2 Serpe Rise, Little Worning, SURREY + Telephone: 09876 5432109 + + Name: Ernest Wright + Dob: 26 April 1978 + Email: ernie@example.com + Address: 1 Wanter Rise, Greater Inncombe, BUCKS + + This will work fine.

There are six people, but only three residences, because +some residences accommodate more than one person. Note also that the +'Residence' descriptor has the entry '%key: Id' whilst the 'Person' +descriptor has '%type: Abode rec Residence'. This is because 'Abode' is +the foreign key which identifies the residence where a person lives. + + We could have declared the 'Id' field as '%auto'. This would have +had the advantage that we need not manually update it. However, we +decided that the 'Abode' field values in the 'Person' records are better +as alphanumeric fields, so that they can contain human readable values. +In this way, it is self-evident by reading a 'Person' record where that +person lives. Yet since the 'Id' field is declared using the '%key' +special field name, you can be sure that you don't accidentally reuse an +existing key. + + +File: recutils.info, Node: Joining Records, Prev: Foreign Keys, Up: Queries which Join Records + +11.2 Joining Records +==================== + +The above example has also added a new field to the 'Person' record set +to contain that person's mobile phone number. Note that the 'Telephone' +field belongs to the 'Residence' record set because that contains the +telephone number of the home, whereas 'Mobile' belongs to 'Person' since +mobile telephones are normally used exclusively by one individual. + + If we want to look up the name and address of a person in our +recfile, we can use 'recsel' as before. Because we now have more than +one record set in the 'acquaintances.rec' file, we have to tell 'recsel' +in which record set we want to look up records. We do this with the +'-t' flag as follows: + + $ recsel -t Person -P Name,Abode acquaintances.rec + Alfred Nebel + 42AbbeterWay + + Mandy Nebel + 42AbbeterWay + + Bertram Nebel + 42AbbeterWay + + Charles Spencer + 2SerpeRise + + Dirk Spencer + 2SerpeRise + + Ernest Wright + ChezGrampa + + This result tells us the names of all the people in the recfile, as +well as giving a concise and hopefully effective reminder telling us +where they live. However these results would not be useful to someone +unacquainted with the individuals. They need a list of names and full +addresses. We can use 'recsel' to produce such a list: + + $ recsel -t Person -j Abode acquaintances.rec + Name: Charles Spencer + Dob: 4 July 1997 + Email: charlie@example.com + Abode_Address: 2 Serpe Rise, Little Worning, SURREY + Abode_Telephone: 09876 5432109 + Abode_Id: 2SerpeRise + + Name: Dirk Spencer + Dob: 29 June 1945 + Email: dirk@example.com + Mobile: 0555 342123 + Abode_Address: 2 Serpe Rise, Little Worning, SURREY + Abode_Telephone: 09876 5432109 + Abode_Id: 2SerpeRise + + Name: Ernest Wright + Dob: 26 April 1978 + Abode_Address: 1 Wanter Rise, Greater Inncombe, BUCKS + Abode_Id: ChezGrampa + + The '-t' flag we have seen before. It tells 'recsel' that we want to +extract records of type 'Person'. The '-j' flag is new. It says that +we want to perform a "join". Specifically we want to join the 'Person' +records according to their 'Abode' field. + + In the above example, 'recsel' displays several field names which do +not appear anywhere in the input e.g. 'Abode_Address'. This is the +'Address' field in the record joined by the foreign key 'Abode'. In +this example probably only the name and address are of interest. The +other information such as date of birth is incidental. The foreign key +'Abode_Id' is certainly not wanted in the output since it is redundant. +As usual, you can use the '-P' or '-p' options to limit the fields which +will be displayed. However the full joined field name, if appropriate, +must be specified. So the names and addresses without the other +information can be retrieved thus: + + $ recsel -t Person -j Abode -p Name,Abode_Address acquaintances.rec + Name: Charles Spencer + Abode_Address: 2 Serpe Rise, Little Worning, SURREY + + Name: Dirk Spencer + Abode_Address: 2 Serpe Rise, Little Worning, SURREY + + Name: Ernest Wright + Abode_Address: 1 Wanter Rise, Greater Inncombe, BUCKS + + +File: recutils.info, Node: Auto-Generated Fields, Next: Encryption, Prev: Queries which Join Records, Up: Top + +12 Auto-Generated Fields +************************ + +Consider for example a list of articles in stock in a toy store: + + %rec: Item + %key: Description + + Description: 2cm metal soldier WWII + Amount: 2111 + + Description: Flying Helicopter Indoor Maxi + Amount: 8 + + ... + + It would be natural to identify the items by their descriptions, but +it is also error prone: was it "Flying Helicopter Indoor Maxi" or +"Flying Helicopter Maxi Indoor"? Was "Helicopter" in lower case or +upper case? + + Thus it is quite common in databases to use some kind of numeric "Id" +to uniquely identify items like those ones, because numbers are easy to +increment and manipulate. So we could add a new numeric 'Id' field and +use it as the primary key: + + %rec: Item + %key: Id + %mandatory: Description + + Id: 0 + Description: 2cm metal soldier WWII + Amount: 2111 + + Id: 1 + Description: Flying Helicopter Indoor Maxi + Amount: 8 + + ... + + A problem with this approach is that we must be careful to not assign +already used ids when we introduce more articles in the database. Other +than its uniqueness, it is not important which number is associated with +which article. + + To ease the management of those Ids database systems use to provide a +facility called "auto-counters". Auto-counters can be implemented in +recfiles using the '%auto' directive in the record descriptor. Its +usage is: + + %auto: FIELD1 FIELD2 ...

The database +can still provide an explicit Id for the new record.

Suppose you maintain a database with +events featuring the following record descriptor: + + %rec: Event + %key: Id + %mandatory: Title Date + +What would be appropriate to identify each event?

In this case the 'Id's would collide. A good +solution is to use 'uuids' and declare them as 'auto': + + %rec: Event + %key: Id + %type: Id uuid + %mandatory: Title Date + + Id: f81d4fae-7dec-11d0-a765-00a0c91e6bf6 + Title: Team meeting + Date: 12-08-2013 + + Id: f81d4fae-dc18-11d0-a765-a01328400a0c + Title: Dave's birthday + Date: 20-12-2013 + + +File: recutils.info, Node: Time-Stamps, Prev: Unique Identifiers, Up: Auto-Generated Fields + +12.3 Time-Stamps +================ + +Auto generated dates can be used to implement automatic timestamps. +Consider for example a "Transfer" record set registering bank transfers. +We want to save a timestamp every time a transfer is done, so we include +an '%auto' for the date: + + %rec: Transfer + %key: Id + %type: Id int + %type: Date date + %auto: Id Date + + +File: recutils.info, Node: Encryption, Next: Generating Reports, Prev: Auto-Generated Fields, Up: Top + +13 Encryption +************* + +For ethical or security reasons it is sometimes necessary that +information in a recfile should not be readable by unauthorized people. +One way to prevent a recfile from being read is to use the security +features of the operating system. A more secure way would be to encrypt +the entire recfile using a free strong encryption program such as GnuPG +(http://gnu.org/software/gnupg). The disadvantage of both these methods +is that the entire recfile has to be secured when it may well be the +case that only certain data need to be protected. + + Recutils offers a way to encrypt specified fields in a record, whilst +leaving the rest in clear text. + +* Menu: + +* Confidential Fields:: Declaring fields as sensitive data. +* Encrypting Files:: Encrypt confidential fields. +* Decrypting Data:: Reading encrypted fields. + + +File: recutils.info, Node: Confidential Fields, Next: Encrypting Files, Up: Encryption + +13.1 Confidential Fields +======================== + +To specify that a field should be encrypted, use the '%confidential' +special field. This special field declares a set of fields as +"confidential", meaning they contain secret data such as passwords or +personal information. Its usage is: + + %confidential: FIELD1 FIELD2 ... FIELDN + +The field names are separated by one or more blank characters. There +can be several '%confidential' fields in the same record descriptor, the +effective list of confidential fields being the union of all the +entries. + + Declaring a field as confidential indicates that its contents must +not be stored in plain text, but encrypted with a password-based +mechanism. When the information is retrieved from the database the +confidential fields are unencrypted if the correct password is provided. +Likewise, when information is inserted in the database the confidential +fields are encrypted with some given password. + + For example, consider a database of users of some service. For each +user we want to store a name, a login name, an email address and a +password. All this information is public with the obvious exception of +the password. Thus we declare the 'Password' field as confidential in +the corresponding record descriptor: + + %rec: Account + %type: Name line + %type: Login line + %type: Email email + %confidential: Password + + The rec format does not impose the usage of a specific encryption +algorithm, but requires that: + + - The algorithm must be password-based. + - The value of any encrypted field shall begin with the string + 'encrypted-' followed by the encrypted data. + - The encrypted data must be encoded in some ASCII encoding such as + base64. + + The above rules assure that it is possible to determine whether a +given field is encrypted. For example, the following is an excerpt from +the account database described above. It contains an entry with the +password encrypted and another with the password unencrypted: + + Name: Mr. Foo + Login: foo + Email: foo@foo.com + Password: encrypted-AAABBBCCDDDEEEFFF + + Name: Mr. Bar + Login: bar + Email: bar@bar.com + Password: secret + + Unencrypted confidential fields are a data integrity error, and +utilities like 'recfix' will report it. The same utility can be used to +"fix" the database by massively encrypting any unencrypted field. + + Nothing prevents the usage of several passwords in the same database. +This allows the establishment of several level of securities or security +profiles. For example, we may want to store different passwords for +different online services: + + %rec: Account + %confidential: WebPassword ShellPassword + +We could then encrypt WebPassword entries using a password shared among +all the webmasters, and the ShellPassword entries with a more restricted +password available only to the administrator of the machine. + + Note that since the utilities only accept to specify one password at +a time different passwords cannot be specified at decryption time. This +means that in the example above the administrator would need to run +'recsel' twice in order to decrypt all the encrypted data in the +recfile. + + The GNU recutils fully support encrypted fields. See the +documentation for 'recsel', 'recins' and 'recfix' for details on how to +operate on files containing confidential fields. + + +File: recutils.info, Node: Encrypting Files, Next: Decrypting Data, Prev: Confidential Fields, Up: Encryption + +13.2 Encrypting Files +===================== + +'recins' allows the insertion of encrypted fields in a database. When +the '-s' ('--password') command line option is specified in the command +line any field declared as confidential in the record descriptor will +get encrypted using the given passphrase. If the command is executed +interactively and '-s' is not used then the user is asked to provide a +password using the terminal. For example, the invocation: + + $ recins -t Account -s mypassword -f Login -v foo -f Password \ + -v secret accounts.rec + +will encrypt the value of the 'Password' field with 'mypassword' as long +as the field is declared as confidential. (*note Confidential Fields:: +for details on confidential fields). + + 'recins' will issue a warning if a confidential field is inserted in +the database but no password was provided to encrypt it. This is to +avoid having unencrypted sensitive data in the recfiles. + + +File: recutils.info, Node: Decrypting Data, Prev: Encrypting Files, Up: Encryption + +13.3 Decrypting Data +==================== + +The contents of confidential fields can be read using the '-s' +('--password') command line option to 'recsel'. When used, any selected +record containing encrypted fields will try to decrypt them with the +given password. If the operation succeeds then the output will include +the unencrypted data. Otherwise the ASCII-encoded encrypted data will +be emitted. + + If 'recsel' is invoked interactively and no password is specified +with '-s', the user will be asked for a password in case one is needed. +No echo of the password will appear in the screen. The provided +password will be used to decrypt all confidential fields as if it was +specified with '-s'. + + For example, consider the following database storing information +about the user accounts of some online service. Each entry stores a +login, a full name, email and a password. The password is declared as +confidential: + + %rec: Account + %key: Login + %confidential: Password + + Login: foo + Name: Mr. Foo + Email: foo@foo.com + Password: encrypted-AAABBBCCCDDD + + Login: bar + Name: Ms. Bar + Email: bar@bar.org + Password: encrypted-XXXYYYZZZUUU + +If we use 'recsel' to get a list of records of type 'Account' without +specifying a password, or if the wrong password was specified in +interactive mode, then we would get the following output with the +encrypted values: + + $ cat accounts.rec | recsel -t Account -p Login,Password + Login: foo + Password: encrypted-AAABBBCCCDDD + + Login: bar + Password: encrypted-XXXYYYZZZUUU + +If we specify a password and both entries were encrypted using that +password, we would get the unencrypted values: + + $ recsel -t Account -s secret -p Login,Password accounts.rec + Login: foo + Password: foosecret + + Login: bar + Password: barsecret + + As mentioned above, a confidential field may be encrypted with +different passwords in different records (*note Confidential Fields::). +For example, we may have an entry in our database with data about the +account of the administrator of the online service.

Such files generally contain tabular data +where the columns are separated by commas and the rows by line feed +and/or carriage return characters. Although record sets are not tables, +tables can be easily emulated using records having the same fields in +the same order. For example: + + a: value + b: value + c: value + + a: value + b: value + c: value + + ... + + In several respects records are more flexible than tables: + + - Fields can appear in a different order in several records. + - There can be several fields with the same name in a single record. + - Records can differ in the number of fields. + + It is evident that records, such as those in recfiles, are a more +general structure than comma separated values. This means that when +converting from csv files to recfiles, certain decisions need to be +made. The 'rec2csv' utility (*note Invoking rec2csv::) implements an +algorithm to deal with this problem and generate a table that the user +expects. + + The algorithm works as follows: + + 1. The utility first scans the specified record set, building a list + with the names that will become the table header. + + 2. For each field, a header is added with the form: + + FIELDNAME[_N] + + where N is a number in the range '2..inf' and is the "index" of the + field in its containing record plus one.

Then duplicates are removed: + + a b b_2 c d + + 4. The resulting list of headers is then used to build the table in + the generated csv file. + + In the above example the result would be + + "a","b","b_2","c","d" + "a1","b11","b12","c1", + "a2","b2",,,"d2" + + As shown, missing fields are implemented as empty columns in the +generated csv. + + +File: recutils.info, Node: Importing MDB Files, Prev: CSV Files, Up: Interoperability + +15.2 Importing MDB Files +======================== + +Access files ("mdb files") are collections of several relations, also +known as tables.

Together, and often +combined with the standard shell utilities, they provide a quite +complete user interface. However, the user's experience can be greatly +improved by a closer integration between the recutils and the shell. +The following sections describe several extensions for 'bash', the GNU +shell (*note (bash)Top::). These extensions make the shell "aware" of +the recutils. + + As with any bash built-in, help is available in the command line +using the 'help' command. For example: + + $ help readrec + + If you installed recutils using a binary package in a GNU/Linux +distribution, odds are that the built-in commands described in this +chapter are already available to you. Otherwise (you get a "command not +found" or similar error) you may have to register the built-in commands +with your bash. This is very easy using the 'enable' bash command. The +registering command for readrec would be: + + $ enable -f readrec.so readrec + + Note however that some systems require the full path to 'readrec.so' +in order for this command to work. + +* Menu: + +* readrec:: Exporting the contents of records to the shell. + + +File: recutils.info, Node: readrec, Up: Bash Builtins + +16.1 readrec +============ + +The bash built-in 'read', when invoked with no options, consumes one +line from standard input and makes it available in the predefined +'REPLY' environment variable, or any other variable whose name is passed +as an argument. This allows processing data structured in lines in a +quite natural way. For example, the following program prints the third +field of each line, with fields separated by commas, until standard +input is exhausted: + + # Process one line at a time. + while read + do + echo "The third field is " `echo $REPLY | cut -d, -f 2` + done + + However, 'read' is not very useful when it comes to processing +recutils records in the shell. Even though it is possible to customize +the character used by 'read' to split the input into records, we would +need to ignore the empty records in the likely case of more than one +empty line separating records. Also, we would need to use 'recsel' to +access to the record fields. Too complicated! + + Thus, the 'readrec' bash built-in is similar to 'read' with the +difference that it reads records instead of lines. It also "exports" +the contents of the record to the user as the values of several +environment variables: + + - 'REPLY_REC' is set to the record read from standard input. + - A set of variables 'FIELD' named after each field found in the + record are set to the (decoded) value of the fields found in the + input record.

The whitespace may be omitted when no ambiguity arises. +The empty string means the beginning of today (i.e., midnight). Order +of the items is immaterial. A date string may contain many flavors of +items: + + * calendar date items + * time of day items + * time zone items + * combined date and time of day items + * day of the week items + * relative items + * pure numbers. + +We describe each of these item types in turn, below. + + A few ordinal numbers may be written out in words in some contexts. +This is most useful for specifying day of the week items or relative +items (see below). Among the most commonly used ordinal numbers, the +word 'last' stands for -1, 'this' stands for 0, and 'first' and 'next' +both stand for 1. Because the word 'second' stands for the unit of time +there is no way to write the ordinal number 2, but for convenience +'third' stands for 3, 'fourth' for 4, 'fifth' for 5, 'sixth' for 6, +'seventh' for 7, 'eighth' for 8, 'ninth' for 9, 'tenth' for 10, +'eleventh' for 11 and 'twelfth' for 12. + + When a month is written this way, it is still considered to be +written numerically, instead of being "spelled in full"; this changes +the allowed strings. + + In the current implementation, only English is supported for words +and abbreviations like 'AM', 'DST', 'EST', 'first', 'January', 'Sunday', +'tomorrow', and 'year'. + + The output of the 'date' command is not always acceptable as a date +string, not only because of the language problem, but also because there +is no standard meaning for time zone items like 'IST'. When using +'date' to generate a date string intended to be parsed later, specify a +date format that is independent of language and that does not use time +zone items other than 'UTC' and 'Z'. Here are some ways to do this: + + $ LC_ALL=C TZ=UTC0 date + Tue Jul 21 23:00:37 UTC 2020 + $ TZ=UTC0 date +'%Y-%m-%d %H:%M:%SZ' + 2020-07-21 23:00:37Z + $ date --rfc-3339=ns # --rfc-3339 is a GNU extension. + 2020-07-21 19:00:37.692722128-04:00 + $ date --rfc-2822 # a GNU extension + Tue, 21 Jul 2020 19:00:37 -0400 + $ date +'%Y-%m-%d %H:%M:%S %z' # %z is a GNU extension. + 2020-07-21 19:00:37 -0400 + $ date +'@%s.%N' # %s and %N are GNU extensions. + @1595372437.692722128 + + Alphabetic case is completely ignored in dates. Comments may be +introduced between round parentheses, as long as included parentheses +are properly nested. Hyphens not followed by a digit are currently +ignored. Leading zeros on numbers are ignored. + + Invalid dates like '2019-02-29' or times like '24:00' are rejected. +In the typical case of a host that does not support leap seconds, a time +like '23:59:60' is rejected even if it corresponds to a valid leap +second. + + +File: recutils.info, Node: Calendar date items, Next: Time of day items, Prev: General date syntax, Up: Date input formats + +20.2 Calendar date items +======================== + +A "calendar date item" specifies a day of the year. It is specified +differently, depending on whether the month is specified numerically or +literally. All these strings specify the same calendar date: + + 2020-07-20 # ISO 8601. + 20-7-20 # Assume 19xx for 69 through 99, + # 20xx for 00 through 68 (not recommended). + 7/20/2020 # Common U.S. writing. + 20 July 2020 + 20 Jul 2020 # Three-letter abbreviations always allowed. + Jul 20, 2020 + 20-jul-2020 + 20jul2020 + + The year can also be omitted. In this case, the last specified year +is used, or the current year if none. For example: + + 7/20 + jul 20 + + Here are the rules. + + For numeric months, the ISO 8601 format 'YEAR-MONTH-DAY' is allowed, +where YEAR is any positive number, MONTH is a number between 01 and 12, +and DAY is a number between 01 and 31. A leading zero must be present +if a number is less than ten. If YEAR is 68 or smaller, then 2000 is +added to it; otherwise, if YEAR is less than 100, then 1900 is added to +it. The construct 'MONTH/DAY/YEAR', popular in the United States, is +accepted. Also 'MONTH/DAY', omitting the year. + + Literal months may be spelled out in full: 'January', 'February', +'March', 'April', 'May', 'June', 'July', 'August', 'September', +'October', 'November' or 'December'. Literal months may be abbreviated +to their first three letters, possibly followed by an abbreviating dot. +It is also permitted to write 'Sept' instead of 'September'. + + When months are written literally, the calendar date may be given as +any of the following: + + DAY MONTH YEAR + DAY MONTH + MONTH DAY YEAR + DAY-MONTH-YEAR + + Or, omitting the year: + + MONTH DAY + + +File: recutils.info, Node: Time of day items, Next: Time zone items, Prev: Calendar date items, Up: Date input formats + +20.3 Time of day items +====================== + +A "time of day item" in date strings specifies the time on a given day. +Here are some examples, all of which represent the same time: + + 20:02:00.000000 + 20:02 + 8:02pm + 20:02-0500 # In EST (U.S. Eastern Standard Time). + + More generally, the time of day may be given as 'HOUR:MINUTE:SECOND', +where HOUR is a number between 0 and 23, MINUTE is a number between 0 +and 59, and SECOND is a number between 0 and 59 possibly followed by '.' +or ',' and a fraction containing one or more digits. Alternatively, +':SECOND' can be omitted, in which case it is taken to be zero. On the +rare hosts that support leap seconds, SECOND may be 60. + + If the time is followed by 'am' or 'pm' (or 'a.m.' or 'p.m.'), HOUR +is restricted to run from 1 to 12, and ':MINUTE' may be omitted (taken +to be zero). 'am' indicates the first half of the day, 'pm' indicates +the second half of the day. In this notation, 12 is the predecessor of +1: midnight is '12am' while noon is '12pm'. (This is the zero-oriented +interpretation of '12am' and '12pm', as opposed to the old tradition +derived from Latin which uses '12m' for noon and '12pm' for midnight.) + + The time may alternatively be followed by a time zone correction, +expressed as 'SHHMM', where S is '+' or '-', HH is a number of zone +hours and MM is a number of zone minutes. The zone minutes term, MM, +may be omitted, in which case the one- or two-digit correction is +interpreted as a number of hours. You can also separate HH from MM with +a colon. When a time zone correction is given this way, it forces +interpretation of the time relative to Coordinated Universal Time (UTC), +overriding any previous specification for the time zone or the local +time zone. For example, '+0530' and '+05:30' both stand for the time +zone 5.5 hours ahead of UTC (e.g., India). This is the best way to +specify a time zone correction by fractional parts of an hour. The +maximum zone correction is 24 hours. + + Either 'am'/'pm' or a time zone correction may be specified, but not +both. + + +File: recutils.info, Node: Time zone items, Next: Combined date and time of day items, Prev: Time of day items, Up: Date input formats + +20.4 Time zone items +==================== + +A "time zone item" specifies an international time zone, indicated by a +small set of letters, e.g., 'UTC' or 'Z' for Coordinated Universal Time. +Any included periods are ignored. By following a non-daylight-saving +time zone by the string 'DST' in a separate word (that is, separated by +some white space), the corresponding daylight saving time zone may be +specified. Alternatively, a non-daylight-saving time zone can be +followed by a time zone correction, to add the two values. This is +normally done only for 'UTC'; for example, 'UTC+05:30' is equivalent to +'+05:30'. + + Time zone items other than 'UTC' and 'Z' are obsolescent and are not +recommended, because they are ambiguous; for example, 'EST' has a +different meaning in Australia than in the United States, and 'A' has +different meaning as a military time zone than as an obsolescent RFC 822 +time zone. Instead, it's better to use unambiguous numeric time zone +corrections like '-0500', as described in the previous section. + + If neither a time zone item nor a time zone correction is supplied, +timestamps are interpreted using the rules of the default time zone +(*note Specifying time zone rules::). + + +File: recutils.info, Node: Combined date and time of day items, Next: Day of week items, Prev: Time zone items, Up: Date input formats + +20.5 Combined date and time of day items +======================================== + +The ISO 8601 date and time of day extended format consists of an ISO +8601 date, a 'T' character separator, and an ISO 8601 time of day.

ISO 8601 fractional minutes and hours are not supported. +Typically, hosts support nanosecond timestamp resolution; excess +precision is silently discarded. + + Here are some examples: + + 2012-09-24T20:02:00.052-05:00 + 2012-12-31T23:59:59,999999999+11:00 + 1970-01-01 00:00Z + + +File: recutils.info, Node: Day of week items, Next: Relative items in date strings, Prev: Combined date and time of day items, Up: Date input formats + +20.6 Day of week items +====================== + +The explicit mention of a day of the week will forward the date (only if +necessary) to reach that day of the week in the future. + + Days of the week may be spelled out in full: 'Sunday', 'Monday', +'Tuesday', 'Wednesday', 'Thursday', 'Friday' or 'Saturday'. Days may be +abbreviated to their first three letters, optionally followed by a +period. The special abbreviations 'Tues' for 'Tuesday', 'Wednes' for +'Wednesday' and 'Thur' or 'Thurs' for 'Thursday' are also allowed. + + A number may precede a day of the week item to move forward +supplementary weeks. It is best used in expression like 'third monday'. +In this context, 'last DAY' or 'next DAY' is also acceptable; they move +one week before or after the day that DAY by itself would represent. + + A comma following a day of the week item is ignored. + + +File: recutils.info, Node: Relative items in date strings, Next: Pure numbers in date strings, Prev: Day of week items, Up: Date input formats + +20.7 Relative items in date strings +=================================== + +"Relative items" adjust a date (or the current date if none) forward or +backward.

These are fuzzy units, as +years and months are not all of equal duration. More precise units are +'fortnight' which is worth 14 days, 'week' worth 7 days, 'day' worth 24 +hours, 'hour' worth 60 minutes, 'minute' or 'min' worth 60 seconds, and +'second' or 'sec' worth one second. An 's' suffix on these units is +accepted and ignored. + + The unit of time may be preceded by a multiplier, given as an +optionally signed number. Unsigned numbers are taken as positively +signed. No number at all implies 1 for a multiplier. Following a +relative item by the string 'ago' is equivalent to preceding the unit by +a multiplier with value -1. + + The string 'tomorrow' is worth one day in the future (equivalent to +'day'), the string 'yesterday' is worth one day in the past (equivalent +to 'day ago'). + + The strings 'now' or 'today' are relative items corresponding to +zero-valued time displacement, these strings come from the fact a +zero-valued time displacement represents the current time when not +otherwise changed by previous items. They may be used to stress other +items, like in '12:00 today'. The string 'this' also has the meaning of +a zero-valued time displacement, but is preferred in date strings like +'this thursday'. + + When a relative item causes the resulting date to cross a boundary +where the clocks were adjusted, typically for daylight saving time, the +resulting date and time are adjusted accordingly. + + The fuzz in units can cause problems with relative items. For +example, '2020-07-31 -1 month' might evaluate to 2020-07-01, because +2020-06-31 is an invalid date. To determine the previous month more +reliably, you can ask for the month before the 15th of the current +month. For example: + + $ date -R + Thu, 31 Jul 2020 13:02:39 -0400 + $ date --date='-1 month' +'Last month was %B?' + Last month was July? + $ date --date="$(date +%Y-%m-15) -1 month" +'Last month was %B!' + Last month was June! + + Also, take care when manipulating dates around clock changes such as +daylight saving leaps. In a few cases these have added or subtracted as +much as 24 hours from the clock, so it is often wise to adopt universal +time by setting the 'TZ' environment variable to 'UTC0' before embarking +on calendrical calculations. + + +File: recutils.info, Node: Pure numbers in date strings, Next: Seconds since the Epoch, Prev: Relative items in date strings, Up: Date input formats + +20.8 Pure numbers in date strings +================================= + +The precise interpretation of a pure decimal number depends on the +context in the date string. + + If the decimal number is of the form YYYYMMDD and no other calendar +date item (*note Calendar date items::) appears before it in the date +string, then YYYY is read as the year, MM as the month number and DD as +the day of the month, for the specified calendar date. + + If the decimal number is of the form HHMM and no other time of day +item appears before it in the date string, then HH is read as the hour +of the day and MM as the minute of the hour, for the specified time of +day. MM can also be omitted. + + If both a calendar date and a time of day appear to the left of a +number in the date string, but no relative item, then the number +overrides the year. + + +File: recutils.info, Node: Seconds since the Epoch, Next: Specifying time zone rules, Prev: Pure numbers in date strings, Up: Date input formats + +20.9 Seconds since the Epoch +============================ + +If you precede a number with '@', it represents an internal timestamp as +a count of seconds. The number can contain an internal decimal point +(either '.' or ','); any excess precision not supported by the internal +representation is truncated toward minus infinity. Such a number cannot +be combined with any other date item, as it specifies a complete +timestamp. + + Internally, computer times are represented as a count of seconds +since an Epoch--a well-defined point of time. On GNU and POSIX systems, +the Epoch is 1970-01-01 00:00:00 UTC, so '@0' represents this time, '@1' +represents 1970-01-01 00:00:01 UTC, and so forth. GNU and most other +POSIX-compliant systems support such times as an extension to POSIX, +using negative counts, so that '@-1' represents 1969-12-31 23:59:59 UTC. + + Most modern systems count seconds with 64-bit two's-complement +integers of seconds with nanosecond subcounts, which is a range that +includes the known lifetime of the universe with nanosecond resolution. +Some obsolescent systems count seconds with 32-bit two's-complement +integers and can represent times from 1901-12-13 20:45:52 through +2038-01-19 03:14:07 UTC. A few systems sport other time ranges. + + On most hosts, these counts ignore the presence of leap seconds. For +example, on most hosts '@1483228799' represents 2016-12-31 23:59:59 UTC, +'@1483228800' represents 2017-01-01 00:00:00 UTC, and there is no way to +represent the intervening leap second 2016-12-31 23:59:60 UTC. + + +File: recutils.info, Node: Specifying time zone rules, Next: Authors of parse_datetime, Prev: Seconds since the Epoch, Up: Date input formats + +20.10 Specifying time zone rules +================================ + +Normally, dates are interpreted using the rules of the current time +zone, which in turn are specified by the 'TZ' environment variable, or +by a system default if 'TZ' is not set. To specify a different set of +default time zone rules that apply just to one date, start the date with +a string of the form 'TZ="RULE"'. The two quote characters ('"') must +be present in the date, and any quotes or backslashes within RULE must +be escaped by a backslash. + + For example, with the GNU 'date' command you can answer the question +"What time is it in New York when a Paris clock shows 6:30am on October +31, 2019?" by using a date beginning with 'TZ="Europe/Paris"' as shown +in the following shell transcript: + + $ export TZ="America/New_York" + $ date --date='TZ="Europe/Paris" 2019-10-31 06:30' + Sun Oct 31 01:30:00 EDT 2019 + + In this example, the '--date' operand begins with its own 'TZ' +setting, so the rest of that operand is processed according to +'Europe/Paris' rules, treating the string '2019-10-31 06:30' as if it +were in Paris. However, since the output of the 'date' command is +processed according to the overall time zone rules, it uses New York +time. (Paris was normally six hours ahead of New York in 2019, but this +example refers to a brief Halloween period when the gap was five hours.) + + A 'TZ' value is a rule that typically names a location in the 'tz' +database (https://www.iana.org/time-zones). A recent catalog of +location names appears in the TWiki Date and Time Gateway +(https://twiki.org/cgi-bin/xtra/tzdatepick.html). A few non-GNU hosts +require a colon before a location name in a 'TZ' setting, e.g., +'TZ=":America/New_York"'. + + The 'tz' database includes a wide variety of locations ranging from +'Arctic/Longyearbyen' to 'Antarctica/South_Pole', but if you are at sea +and have your own private time zone, or if you are using a non-GNU host +that does not support the 'tz' database, you may need to use a POSIX +rule instead. Simple POSIX rules like 'UTC0' specify a time zone +without daylight saving time; other rules can specify simple daylight +saving regimes. *Note Specifying the Time Zone with 'TZ': (libc)TZ +Variable. + + +File: recutils.info, Node: Authors of parse_datetime, Prev: Specifying time zone rules, Up: Date input formats + +20.11 Authors of 'parse_datetime' +================================= + +'parse_datetime' started life as 'getdate', as originally implemented by +Steven M. Bellovin (<smb@research.att.com>) while at the University of +North Carolina at Chapel Hill. The code was later tweaked by a couple +of people on Usenet, then completely overhauled by Rich $alz +(<rsalz@bbn.com>) and Jim Berets (<jberets@bbn.com>) in August, 1990. +Various revisions for the GNU system were made by David MacKenzie, Jim +Meyering, Paul Eggert and others, including renaming it to 'get_date' to +avoid a conflict with the alternative Posix function 'getdate', and a +later rename to 'parse_datetime'. The Posix function 'getdate' can +parse more locale-specific dates using 'strptime', but relies on an +environment variable and external file, and lacks the thread-safety of +'parse_datetime'. + + This chapter was originally produced by Franc,ois Pinard +(<pinard@iro.umontreal.ca>) from the 'parse_datetime.y' source code, and +then edited by K.

PREAMBLE + + The purpose of this License is to make a manual, textbook, or other + functional and useful document "free" in the sense of freedom: to + assure everyone the effective freedom to copy and redistribute it, + with or without modifying it, either commercially or + noncommercially. Secondarily, this License preserves for the + author and publisher a way to get credit for their work, while not + being considered responsible for modifications made by others. + + This License is a kind of "copyleft", which means that derivative + works of the document must themselves be free in the same sense. + It complements the GNU General Public License, which is a copyleft + license designed for free software. + + We have designed this License in order to use it for manuals for + free software, because free software needs free documentation: a + free program should come with manuals providing the same freedoms + that the software does. But this License is not limited to + software manuals; it can be used for any textual work, regardless + of subject matter or whether it is published as a printed book. We + recommend this License principally for works whose purpose is + instruction or reference. + + 1. APPLICABILITY AND DEFINITIONS + + This License applies to any manual or other work, in any medium, + that contains a notice placed by the copyright holder saying it can + be distributed under the terms of this License. Such a notice + grants a world-wide, royalty-free license, unlimited in duration, + to use that work under the conditions stated herein. The + "Document", below, refers to any such manual or work. Any member + of the public is a licensee, and is addressed as "you". You accept + the license if you copy, modify or distribute the work in a way + requiring permission under copyright law. + + A "Modified Version" of the Document means any work containing the + Document or a portion of it, either copied verbatim, or with + modifications and/or translated into another language. + + A "Secondary Section" is a named appendix or a front-matter section + of the Document that deals exclusively with the relationship of the + publishers or authors of the Document to the Document's overall + subject (or to related matters) and contains nothing that could + fall directly within that overall subject. (Thus, if the Document + is in part a textbook of mathematics, a Secondary Section may not + explain any mathematics.) The relationship could be a matter of + historical connection with the subject or with related matters, or + of legal, commercial, philosophical, ethical or political position + regarding them. + + The "Invariant Sections" are certain Secondary Sections whose + titles are designated, as being those of Invariant Sections, in the + notice that says that the Document is released under this License. + If a section does not fit the above definition of Secondary then it + is not allowed to be designated as Invariant. The Document may + contain zero Invariant Sections. If the Document does not identify + any Invariant Sections then there are none. + + The "Cover Texts" are certain short passages of text that are + listed, as Front-Cover Texts or Back-Cover Texts, in the notice + that says that the Document is released under this License. A + Front-Cover Text may be at most 5 words, and a Back-Cover Text may + be at most 25 words. + + A "Transparent" copy of the Document means a machine-readable copy, + represented in a format whose specification is available to the + general public, that is suitable for revising the document + straightforwardly with generic text editors or (for images composed + of pixels) generic paint programs or (for drawings) some widely + available drawing editor, and that is suitable for input to text + formatters or for automatic translation to a variety of formats + suitable for input to text formatters. A copy made in an otherwise + Transparent file format whose markup, or absence of markup, has + been arranged to thwart or discourage subsequent modification by + readers is not Transparent. An image format is not Transparent if + used for any substantial amount of text. A copy that is not + "Transparent" is called "Opaque". + + Examples of suitable formats for Transparent copies include plain + ASCII without markup, Texinfo input format, LaTeX input format, + SGML or XML using a publicly available DTD, and standard-conforming + simple HTML, PostScript or PDF designed for human modification. + Examples of transparent image formats include PNG, XCF and JPG. + Opaque formats include proprietary formats that can be read and + edited only by proprietary word processors, SGML or XML for which + the DTD and/or processing tools are not generally available, and + the machine-generated HTML, PostScript or PDF produced by some word + processors for output purposes only. + + The "Title Page" means, for a printed book, the title page itself, + plus such following pages as are needed to hold, legibly, the + material this License requires to appear in the title page. For + works in formats which do not have any title page as such, "Title + Page" means the text near the most prominent appearance of the + work's title, preceding the beginning of the body of the text. + + The "publisher" means any person or entity that distributes copies + of the Document to the public. + + A section "Entitled XYZ" means a named subunit of the Document + whose title either is precisely XYZ or contains XYZ in parentheses + following text that translates XYZ in another language. (Here XYZ + stands for a specific section name mentioned below, such as + "Acknowledgements", "Dedications", "Endorsements", or "History".) + To "Preserve the Title" of such a section when you modify the + Document means that it remains a section "Entitled XYZ" according + to this definition. + + The Document may include Warranty Disclaimers next to the notice + which states that this License applies to the Document. These + Warranty Disclaimers are considered to be included by reference in + this License, but only as regards disclaiming warranties: any other + implication that these Warranty Disclaimers may have is void and + has no effect on the meaning of this License. + + 2. VERBATIM COPYING + + You may copy and distribute the Document in any medium, either + commercially or noncommercially, provided that this License, the + copyright notices, and the license notice saying this License + applies to the Document are reproduced in all copies, and that you + add no other conditions whatsoever to those of this License. You + may not use technical measures to obstruct or control the reading + or further copying of the copies you make or distribute. However, + you may accept compensation in exchange for copies. If you + distribute a large enough number of copies you must also follow the + conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + + 3. COPYING IN QUANTITY + + If you publish printed copies (or copies in media that commonly + have printed covers) of the Document, numbering more than 100, and + the Document's license notice requires Cover Texts, you must + enclose the copies in covers that carry, clearly and legibly, all + these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the title + equally prominent and visible. You may add other material on the + covers in addition. Copying with changes limited to the covers, as + long as they preserve the title of the Document and satisfy these + conditions, can be treated as verbatim copying in other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a machine-readable + Transparent copy along with each Opaque copy, or state in or with + each Opaque copy a computer-network location from which the general + network-using public has access to download using public-standard + network protocols a complete Transparent copy of the Document, free + of added material. If you use the latter option, you must take + reasonably prudent steps, when you begin distribution of Opaque + copies in quantity, to ensure that this Transparent copy will + remain thus accessible at the stated location until at least one + year after the last time you distribute an Opaque copy (directly or + through your agents or retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of copies, + to give them a chance to provide you with an updated version of the + Document. + + 4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with the + Modified Version filling the role of the Document, thus licensing + distribution and modification of the Modified Version to whoever + possesses a copy of it. In addition, you must do these things in + the Modified Version: + + A. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of previous + versions (which should, if there were any, be listed in the + History section of the Document). You may use the same title + as a previous version if the original publisher of that + version gives permission. + + B. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in + the Modified Version, together with at least five of the + principal authors of the Document (all of its principal + authors, if it has fewer than five), unless they release you + from this requirement. + + C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + D. Preserve all the copyright notices of the Document. + + E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + F. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified + Version under the terms of this License, in the form shown in + the Addendum below. + + G. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's + license notice. + + H. Include an unaltered copy of this License. + + I. Preserve the section Entitled "History", Preserve its Title, + and add to it an item stating at least the title, year, new + authors, and publisher of the Modified Version as given on the + Title Page. If there is no section Entitled "History" in the + Document, create one stating the title, year, authors, and + publisher of the Document as given on its Title Page, then add + an item describing the Modified Version as stated in the + previous sentence. + + J. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in the + "History" section. You may omit a network location for a work + that was published at least four years before the Document + itself, or if the original publisher of the version it refers + to gives permission. + + K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section + all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + + L. Preserve all the Invariant Sections of the Document, unaltered + in their text and in their titles. Section numbers or the + equivalent are not considered part of the section titles. + + M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. + + N. Do not retitle any existing section to be Entitled + "Endorsements" or to conflict in title with any Invariant + Section. + + O. Preserve any Warranty Disclaimers. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no + material copied from the Document, you may at your option designate + some or all of these sections as invariant. To do this, add their + titles to the list of Invariant Sections in the Modified Version's + license notice. These titles must be distinct from any other + section titles. + + You may add a section Entitled "Endorsements", provided it contains + nothing but endorsements of your Modified Version by various + parties--for example, statements of peer review or that the text + has been approved by an organization as the authoritative + definition of a standard. + + You may add a passage of up to five words as a Front-Cover Text, + and a passage of up to 25 words as a Back-Cover Text, to the end of + the list of Cover Texts in the Modified Version. Only one passage + of Front-Cover Text and one of Back-Cover Text may be added by (or + through arrangements made by) any one entity. If the Document + already includes a cover text for the same cover, previously added + by you or by arrangement made by the same entity you are acting on + behalf of, you may not add another; but you may replace the old + one, on explicit permission from the previous publisher that added + the old one. + + The author(s) and publisher(s) of the Document do not by this + License give permission to use their names for publicity for or to + assert or imply endorsement of any Modified Version. + + 5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination all + of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice, and that you preserve all + their Warranty Disclaimers. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else a + unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections Entitled + "History" in the various original documents, forming one section + Entitled "History"; likewise combine any sections Entitled + "Acknowledgements", and any sections Entitled "Dedications". You + must delete all sections Entitled "Endorsements." + + 6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the documents + in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow this + License in all other respects regarding verbatim copying of that + document. + + 7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of a + storage or distribution medium, is called an "aggregate" if the + copyright resulting from the compilation is not used to limit the + legal rights of the compilation's users beyond what the individual + works permit. When the Document is included in an aggregate, this + License does not apply to the other works in the aggregate which + are not themselves derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one half + of the entire aggregate, the Document's Cover Texts may be placed + on covers that bracket the Document within the aggregate, or the + electronic equivalent of covers if the Document is in electronic + form. Otherwise they must appear on printed covers that bracket + the whole aggregate. + + 8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of section + 4. Replacing Invariant Sections with translations requires special + permission from their copyright holders, but you may include + translations of some or all Invariant Sections in addition to the + original versions of these Invariant Sections. You may include a + translation of this License, and all the license notices in the + Document, and any Warranty Disclaimers, provided that you also + include the original English version of this License and the + original versions of those notices and disclaimers. In case of a + disagreement between the translation and the original version of + this License or a notice or disclaimer, the original version will + prevail. + + If a section in the Document is Entitled "Acknowledgements", + "Dedications", or "History", the requirement (section 4) to + Preserve its Title (section 1) will typically require changing the + actual title. + + 9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided under this License. Any attempt + otherwise to copy, modify, sublicense, or distribute it is void, + and will automatically terminate your rights under this License. + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly and + finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate + the licenses of parties who have received copies or rights from you + under this License. If your rights have been terminated and not + permanently reinstated, receipt of a copy of some or all of the + same material does not give you any rights to use it. + + 10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + <http://www.gnu.org/copyleft/>. + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If the + Document does not specify a version number of this License, you may + choose any version ever published (not as a draft) by the Free + Software Foundation. If the Document specifies that a proxy can + decide which future versions of this License can be used, that + proxy's public statement of acceptance of a version permanently + authorizes you to choose that version for the Document. + + 11. RELICENSING + + "Massive Multiauthor Collaboration Site" (or "MMC Site") means any + World Wide Web server that publishes copyrightable works and also + provides prominent facilities for anybody to edit those works. A + public wiki that anybody can edit is an example of such a server. + A "Massive Multiauthor Collaboration" (or "MMC") contained in the + site means any set of copyrightable works thus published on the MMC + site. + + "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 + license published by Creative Commons Corporation, a not-for-profit + corporation with a principal place of business in San Francisco, + California, as well as future copyleft versions of that license + published by that same organization. + + "Incorporate" means to publish or republish a Document, in whole or + in part, as part of another Document. + + An MMC is "eligible for relicensing" if it is licensed under this + License, and if all works that were first published under this + License somewhere other than this MMC, and subsequently + incorporated in whole or in part into the MMC, (1) had no cover + texts or invariant sections, and (2) were thus incorporated prior + to November 1, 2008. + + The operator of an MMC Site may republish an MMC contained in the + site under CC-BY-SA on the same site at any time before August 1, + 2009, provided the MMC is eligible for relicensing. + +ADDENDUM: How to use this License for your documents +==================================================== + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts. A copy of the license is included in the section entitled ``GNU + Free Documentation License''. + + If you have Invariant Sections, Front-Cover Texts and Back-Cover +Texts, replace the "with...Texts." line with this: + + with the Invariant Sections being LIST THEIR TITLES, with + the Front-Cover Texts being LIST, and with the Back-Cover Texts + being LIST. + + If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + + If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of free +software license, such as the GNU General Public License, to permit +their use in free software. + + +File: recutils.info, Node: Concept Index, Prev: GNU Free Documentation License, Up: Top + +Concept Index +************* + +�[index�] +* Menu: + +* %allowed: Allowed Fields.

recutils. +* A Little Example:: Recutils in action. +@end menu + +@node Purpose +@section Purpose + +GNU recutils is a set of tools and libraries to access human-editable, +text-based databases called @emph{recfiles}. The data is stored as a +sequence of records, each record containing an arbitrary number of +named fields. Advanced capabilities usually found in other data +storage systems are supported: data types, data integrity (keys, +mandatory fields, @etc{}) as well as the ability of records to refer to +other records (sort of foreign keys). Despite its simplicity, +recfiles can be used to store medium-sized databases. + +So, yet another data storage system? The mere existence of this +package deserves an explanation. There is a rich set of already +available free data storage systems, covering a broad range of +requirements. Big systems having complex data storage requirements +will probably make use of some full-fledged relational system such as +MySQL or PostgreSQL@. Less demanding applications, or applications +with special deployment requirements, may find it more convenient to +use a simpler system such as SQLite, where the data is stored in a +single binary file. XML files are often used to store configuration +settings for programs, and to encode data for transmission through +networks. + +So it looks like all the needs are covered by the existing +solutions @dots{} but consider the following characteristics of the +data storage systems mentioned in the previous paragraph: + +@itemize @minus +@item The stored data is not directly human readable. +@item The stored data is definitely not directly writable by humans. +@item They are program dependent. +@item They are not easily managed by version control systems. +@end itemize + +@cindex readability +Regarding the first point (human readability), while it is clearly +true for the binary files, some may argue XML files are indeed human +readable@dots{} well@dots{} @code{<bar><foo tag="val">try</foo> to r&iamp;ead +<p>this</p></bar>}. YAML @footnote{Yet Another Markup Language} is an +example of a hierarchical data storage format which is much more +readable than XML@. The problem with YAML is that it was designed as a +``data serialization language'' and thus to map the data constructs +usually found in programming languages. That makes it too complex for +the simple task of storing plain lists of items. + +Recfiles are human-readable, human-writable and still easy to +parse and to manipulate automatically. Obviously they are not +suitable for any task (for example, it can be difficult to manage +hierarchies in recfiles) and performance is somewhat sacrificed in +favor of readability. But they are quite handy to store small to +medium simple databases. + +The GNU recutils suite comprises: + +@itemize @minus +@item This Texinfo manual, describing the Rec format and the accompanying software. +@item A C library (librec) that provides a rich set of functions to manipulate rec data. +@item A set utilities that can be used in shell scripts and in the command line to operate on rec files. +@item An emacs mode, @code{rec-mode}. +@end itemize + +@node A Little Example +@section A Little Example + +@cindex books +Everyone loves to grow a nice book collection at home. Unfortunately, +in most cases the management of our private books gets uncontrolled: +some books get lost, some of them may be loaned to some friend, there +are some duplicated (or even triplicated!) titles because we forgot +about the existence of the previous copy, and many more details. + +In order to improve the management of our little book collection we +could make use of a complex data storage system such as a relational +database. The problem with that approach, as explained in the +previous section, is that the tool is too complicated for the simple +task: we do not need the full power of a relational database system to +maintain a simple collection of books. + +With GNU recutils it is possible to maintain such a little database in +a text file. Let's call it @file{books.rec}.

This chapter shows you how, by observing these rules, recfiles +of arbitrary complexity can be written. + +@menu +* Fields:: The key--value pairs which comprise the data. +* Records:: The main entities of a recfile. +* Comments:: Information for humans' benefit only. +* Record Descriptors:: Describing different types of records. +@end menu + +@node Fields +@section Fields + +@cindex field +A @dfn{field} is the written form of an association between a label +and a value. For example, if we wanted to associate the label +@code{Name} with the value @code{Ada Lovelace} we would write: + +@example +Name: Ada Lovelace +@end example + +The separator between the field name and the field value is a colon +followed by a blank character (space and tabs, but not newlines). The +name of the field shall begin in the first column of the line. + +@cindex field name +A @dfn{field name} is a sequence of alphanumeric characters plus +underscores (@code{_}), starting with a letter or the character +@code{%}. The regular expression denoting a field name is: + +@example +[a-zA-Z%][a-zA-Z0-9_]* +@end example + +@cindex case, in field names +Field names are case-sensitive. @code{Foo} and @code{foo} are +different field names. + +The following list contains valid field names (the final colon is not +part of the names): + +@example +Foo: +foo: +A23: +ab1: +A_Field: +@end example + +@cindex field values +The @dfn{value of a field} is a sequence of characters terminated by a +single newline character (@code{\n}). + +@cindex multiline field values +Sometimes a value is too long to fit in the usual width of terminals +and screens. In that case, depending on the specific tool used to +access the file, the readability of the data would not be that good. +It is therefore possible to physically split a logical line by +escaping a newline with a backslash character, as in: + +@example +LongLine: This is a quite long value \ +comprising a single unique logical line \ +split in several physical lines. +@end example + +The sequence @code{\n} (newline) @code{+} (PLUS) and an optional +@code{_} (SPACE) is interpreted as a newline when found in a field +value. For example, the C string @code{"bar1\nbar2\n bar3"} would be +encoded in the following way in a field value: + +@example +Foo: bar1 ++ bar2 ++ bar3 +@end example + +@node Records +@section Records + +@cindex record +A @dfn{record} is a group of one or more fields written one after the +other: + +@example +Name1: Value1 +Name2: Value2 +Name2: Value3 +@end example + +It is possible for several fields in a record to share the same name +or/and the field value. The following is a valid record containing +three fields: + +@example +Name: John Smith +Email: john.smith@@foomail.com +Email: john@@smith.name +@end example + +@cindex record size +@cindex size, record size +The @dfn{size of a record} is defined as the number of fields that it +contains. A record cannot be empty, so the minimum size +for a record is 1. The maximum number of fields for a record is only +limited by the available physical resources. The size of the previous +record is 3. + +Records are separated by one or more blank lines. For instance, the +following example shows a file named @file{personalities.rec} +featuring three records: + +@example +Name: Ada Lovelace +Age: 36 + +Name: Peter the Great +Age: 53 + +Name: Matusalem +Age: 969 +@end example + +@node Comments +@section Comments + +@cindex comments +Any line having an @code{#} (ASCII 0x23) character in the first column +is a comment line. + +Comments may be used to insert information that +is not part of the database but useful in other ways. +They are completely ignored by processing tools and can only be seen by +looking at the recfile itself. + +It is also quite convenient to comment-out information from the +recfile without having to remove it in a definitive way: you may want +to recover the data into the database later! Comment lines can be +used to comment-out both full registers and single fields: + +@example +Name: Jose E. Marchesi +# Occupation: Software Engineer +# Severe lack of brain capacity +# Fired on 02/01/2009 (without compensation) +Occupation: Unoccupied +@end example + +Comments are also useful for headers, footers, comment blocks and all +kind of markers: + +@example +# -*- mode: rec -*- +# +# TODO +# +# This file contains the Bugs database of GNU recutils. +# +# Blah blah@dots{} + +@dots{} + +# End of TODO +@end example + + +Unlike some file formats, comments in recfiles must be complete lines. +You cannot start a comment in the middle of a line. +For example, in the following record, the @code{#} does @emph{not} start a comment: +@example +Name: Peter the Great # Russian Tsar +Age: 53 +@end example + +@node Record Descriptors +@section Record Descriptors + +@cindex descriptor +Certain properties of a set of records can be specified by preceding +them with a @dfn{record descriptor}. A record descriptor is itself a +record, and uses fields with some predefined names to store +properties. + +@menu +* Record Sets:: Defining different types of records. +* Naming Record Types:: Some conventions on naming record sets. +* Documenting Records:: Documenting your record sets. +* Record Sets Properties:: Introducing the special fields. +@end menu + +@node Record Sets +@subsection Record Sets +@cindex record sets + +The most basic property that can be specified for a set of records is +their @dfn{type}. The special field name @code{%rec} is used for that +purpose: + +@cindex @code{%rec} +@example +%rec: Entry + +Id: 1 +Name: Entry 1 + +Id: 2 +Name: Entry 2 +@end example + +The records following the descriptors are then identified as having +its type. So in the example above we would say there are two records +of type ``Entry''. Or in a more colloquial way we would say there are +two ``Entries'' in the database. + +The effect of a record descriptor ends when another descriptor is +found in the stream of records. This allows you to store different kinds +of records in the same database. For example, suppose you are +maintaining a depot. You will need to keep track of both what items +are available and when they are sold or restocked. + +The following example shows the usage of two record descriptors to +store both kind of records: articles and stock. + +@example +%rec: Article + +Id: 1 +Title: Article 1 + +Id: 2 +Title: Article 2 + +%rec: Stock + +Id: 1 +Type: sell +Date: 20 April 2011 + +Id: 2 +Type: stock +Date: 21 April 2011 +@end example + +The collection of records having same types in recfiles are known as +@dfn{record sets} in recutils jargon. In the example above two +record sets are defined: one containing articles and the other +containing stock movements. + +Nothing prevents having empty record sets in databases. This is in fact +usually the case when a new recfile is written but no data exists yet. +In our depot example we could write a first version of the database +containing just the record descriptors: + +@example +%rec: Article + +%rec: Stock +@end example + +@cindex default record types +Special records are not required, and many recfiles do not have them. +This is because +all the records contained in the file are of the same type, and their +nature can usually be inferred from both the file name and their +contents. For example, @file{contacts.rec} could simply contain +records representing contacts without an explicit @code{%rec: Contact} +record descriptor. In this case we say that the type of the anonymous +records stored in the file is the @dfn{default record type}. + +Another possible situation, although not usual, is to have a recfile +containing both non-typed (default) and typed record types: + +@example +Id: 1 +Title: Blah + +Id: 2 +Title: Bleh + +%rec: Movement + +Date: 13-Aug-2012 +Concept: 20 + +Date: 24-Sept-2012 +Concept: 12 +@end example + +@noindent +In this case the records preceding the movements are of the +``default'' type, whereas the records following the record descriptor +are of type @code{Movement}. Even though it is supported by the format +and the utilities, it is generally not recommended to mix non-typed +and typed records in a recfile. + +@node Naming Record Types +@subsection Naming Record Types + +It is up to you how to name your record sets. Any string comprising +only alphanumeric characters or underscores, and that starts with a +letter will be a legal name. However, it is recommended to use the +singular form of a noun in order to describe the ``type'' of the +records in the records set. Examples are @code{Article}, +@code{Contributor}, @code{Employee} and @code{Movement}. + +The used noun should be specific enough in order to characterize the +property of the records which matters. For example, in a +contributor's database it would be better to have a record set named +@code{Contributor} than @code{Person}. + +The reason of using singular nouns instead of their plural forms is +that it works better with the utilities: it is more natural to read +@command{recsel -t Contributor} (@command{-t} is for ``type'') than +@command{recsel -t Contributors}. + +@node Documenting Records +@subsection Documenting Records + +@cindex @code{%doc} +@cindex documentation fields +@cindex description of record sets + +As well as a name, it is a good idea to provide a description of the record set. +This is sometimes called the record set's @dfn{documentation} and is specified +using the @code{%doc} field. + +Whereas the name is usually short and can contain only alphanumeric +characters and underscores, no such restriction applies to the +documentation. The documentation is typically more verbose than the +name provided by the @code{%rec} field and may contain arbitrary +characters such as punctuation and parentheses. It is somewhat +similar to a comment (@pxref{Comments}), but it can be managed more easily +in a programmatic way. Unlike a comment, the @code{%doc} field is +recognized by tools such as @command{recinf} (@pxref{Invoking recinf}) +which processes record descriptors. For example, you might have two +record sets with @code{%rec} and @code{%doc} fields as follows: + +@example +%rec: Contact +%doc: Family, friends and acquaintances (other than business). + +Name: Granny +Phone: +12 23456677 + +Name: Edwina +Phone: +55 0923 8765 + + +%rec: Associate +%doc: Colleagues and other business contacts + +Name: Karl Schmidt +Phone: +49 88234566 + +Name: Genevieve Curie +Phone: +33 34 87 65 +@end example + +@node Record Sets Properties +@subsection Record Sets Properties + +@cindex field, special fields +@cindex special fields +Besides determining the type of record that follows in the +stream, record descriptors can be used to describe other properties of +those records. This can be done by using @dfn{special +fields}, which have special names from a predefined set. +Consider for example the following database, where record descriptors +are used to specify a (optional) numeric `Id' and a mandatory `Title' field: + +@cindex @code{%mandatory} +@cindex mandatory fields +@example +%rec: Item +%type: Id int +%mandatory: Title + +Id: 10 +Title: Notebook (big) + +Id: 11 +Title: Fountain Pen +@end example + +Note that the names of special fields always start with the character +@code{%}. Also note that it is also possible to use non-special +fields in a record descriptor, but such fields will have no effect on +the described record set. + +Every record set must contain one, and only one, field named +@code{%rec}. It is not mandated that that field must occupy the first +position in the record. However, it is considered a good style to +place it as the first field in the record set, in order for the casual +reader to easily identify the type of the records. + +The following list briefly describes the special fields defined in the +recutils format, along with references to the sections of this manual +describing their usage in depth. + +@cindex special fields, list of +@table @code +@item %rec +Naming record types.

Or +you could use a standard tool such as @command{grep} to extract +strings matching a pattern. However, recutils provides a more powerful +and flexible way to lookup data. The following sections explore how +the recutils can be used in order to extract data from recfiles, from +very basic and simple queries to quite complex examples. + +@menu +* Simple Selections:: Introducing @command{recsel}. +* Selecting by Type:: Get the records of some given type. +* Selecting by Position:: Get the record occupying some position. +* Random Records:: Get a set of random records. +* Selection Expressions:: Get the records satisfying some expression. +* Field Expressions:: Selecting a subset of fields. +* Sorted Output:: Get the records in a given order. +@end menu + +@node Simple Selections +@section Simple Selections + +@command{recsel} is an utility whose primary purpose is to select +records from a recfile and print them on standard output. +Consider the following example record set, which we shall assume is +saved in a recfile called @file{acquaintances.rec}: + +@example +# This database contains a list of both real and fictional people +# along with their age. + +Name: Ada Lovelace +Age: 36 + +Name: Peter the Great +Age: 53 + +# Name: Matusalem +# Age: 969 + +Name: Bart Simpson +Age: 10 + +Name: Adrian Mole +Age: 13.75 +@end example + +@noindent +If we invoke @command{recsel acquaintances.rec} we will get a list of +all the records stored in the file in the terminal: + +@example +$ recsel acquaintances.rec +Name: Ada Lovelace +Age: 36 + +Name: Peter the Great +Age: 53 + +Name: Bart Simpson +Age: 10 + +Name: Adrian Mole +Age: 13.75 +@end example + +@noindent +Note that the commented out parts of the file, in this case the +explanatory header and the record corresponding to Matusalem, are not +part of the output produced by @command{recsel}. This is because +@command{recsel} is concerned only with the data. + +@command{recsel} will also ``pack'' the records so any extra empty +lines that may be between records are not echoed in the output: + +@multitable @columnfractions .5 .5 +@item +@example +@strong{acquaintances.rec:} + +Name: Peter the Great +Age: 53 + +# Note the extra empty lines. + + +Name: Bart Simpson +Age: 10 +@end example +@tab +@example +$ recsel acquaintances.rec +Name: Peter the Great +Age: 53 + +Name: Bart Simpson +Age: 10 +@end example +@end multitable + +@noindent +It is common to store data gathered in several recfiles. +For example, we could have a @file{contacts.rec} file containing +general contact records, and also a @file{work-contacts.rec} file +containing business contacts: + +@multitable @columnfractions .5 .5 +@item +@example +@strong{contacts.rec:} + +Name: Granny +Phone: +12 23456677 + +Name: Doctor +Phone: +12 58999222 +@end example +@tab +@example +@strong{work-contacts.rec:} + +Name: Yoyodyne Corp. +Email: sales@@yoyod.com +Phone: +98 43434433 + +Name: Robert Harris +Email: robert.harris@@yoyod.com +Note: Sales Department. +@end example +@end multitable + +Both files can be passed to @command{recsel} in the command line. In +that case @command{recsel} will simply process them and output their +records in the same order they were specified: + +@example +$ recsel contacts.rec work-contacts.rec +Name: Granny +Phone: +12 23456677 + +Name: Doctor +Phone: +12 58999222 + +Name: Yoyodyne Corp. +Email: sales@@yoyod.com +Phone: +98 43434433 + +Name: Robert Harris +Email: robert.harris@@yoyod.com +Note: Sales Department. +@end example + +@noindent +As mentioned above, the output follows the ordering on the command +line, so @command{recsel work-contacts.rec +contacts.rec} would output the records of @file{work-contacts.rec} first +and then the ones from @file{contacts.rec}. + +@noindent +Note however that @command{recsel} will merge records from several +files specified in the command line only if they are anonymous. If +the contacts in our files were typed: + +@multitable @columnfractions .5 .5 +@item +@example +@strong{contacts.rec:} + +%rec: Contact + +Name: Granny +Phone: +12 23456677 + +Name: Doctor +Phone: +12 58999222 +@end example +@tab +@example +@strong{work-contacts.rec:} + +%rec: Contact + +Name: Yoyodyne Corp. +Email: sales@@yoyod.com +Phone: +98 43434433 + +Name: Robert Harris +Email: robert.harris@@yoyod.com +Note: Sales Department. +@end example +@end multitable + +@noindent +Then we would get the following error message: + +@example +$ recsel contacts.rec work-contacts.rec +recsel: error: duplicated record set 'Contact' from work-contacts.rec. +@end example + + +@node Selecting by Type +@section Selecting by Type + +As we saw in the section discussing record descriptors, it is possible +to have several different types of records in a single recfile. +Consider for example a @file{gnu.rec} file containing information +about maintainers and packages in the GNU Project: + +@example +%rec: Maintainer + +Name: Jose E. Marchesi +Email: jemarch@@gnu.org + +Name: Luca Saiu +Email: positron@@gnu.org + +%rec: Package + +Name: GNU recutils +LastRelease: 12 February 2014 + +Name: GNU epsilon +LastRelease: 10 March 2013 +@end example + +@noindent If @command{recsel} is invoked in that file it will complain: + +@example +$ recsel gnu.rec +recsel: error: several record types found. Please use -t to specify one. +@end example + +@noindent +This is because @command{recsel} does not know which records to +output: the maintainers or the packages. This can be resolved by +using the @code{-t} command line option: + +@example +$ recsel -t Package gnu.rec +Name: GNU recutils +LastRelease: 12 February 2014 + +Name: GNU epsilon +LastRelease: 10 March 2013 +@end example + +@noindent +By default @command{recsel} never outputs record descriptors. This is +because most of the time the user is only interested in the data. +However, with the @code{-d} command line option, the record descriptor +of the selected type is printed preceding the data records: + +@example +$ recsel -d -t Maintainer gnu.rec +%rec: Maintainer + +Name: Jose E. Marchesi +Email: jemarch@@gnu.org + +Name: Luca Saiu +Email: positron@@gnu.org +@end example + +@noindent +Note that at the moment it is not possible to select non-typed +(default) records when other record sets are stored in the same file. +This is one of the reasons why mixing non-typed records and typed +records in a single recfile is not recommended. + +@noindent +Note also that if a nonexistent record type is specified in @code{-t} +then @command{recsel} does nothing. + +@node Selecting by Position +@section Selecting by Position + +As was explained in the previous sections, @command{recsel} outputs +all the records of some record set. The records are echoed in the +same order they are written in the recfile. However, often it is +desirable to select a subset of the records, determined by the position +they occupy in their record set. + +The @code{-n} command line option to @command{recsel} supports doing +this in a natural way. This is how we would retrieve the first +contact listed in a contacts database using @command{recsel}: + +@example +$ recsel -n 0 contacts.rec +Name: Granny +Phone: +12 23456677 +@end example + +@noindent +Note that the index is zero-based. If we want to retrieve more +records we can specify several indexes to @code{-n} separated by +commas. If a given index is too big, it is simply ignored: + +@example +$ recsel -n 0,1,999 contacts.rec +Name: Granny +Phone: +12 23456677 + +Name: Doctor +Phone: +12 58999222 +@end example + +@noindent With @code{-n}, the order in which the records are echoed does not +depend on the order of the indexes passed to @code{-n}. +For example, the output of @command{recsel -n 0,1} will be +identical to the output of @command{recsel -n 1,0}. + +Ranges of indexes can also be used to select a subset of the records. +For example, the following call would also select the first three +contacts of the database: + +@example +$ recsel -n 0-2 contacts.rec +Name: Granny +Phone: +12 23456677 + +Name: Doctor +Phone: +12 58999222 + +Name: Dad +Phone: +12 88229900 +@end example + +@noindent It is possible to mix single indexes and index +ranges in the same call. For example, @command{recsel -n 0,5-6} would +select the first, sixth and seventh records. + +@node Random Records +@section Random Records + +Consider a database in which each record is a cooking recipe. It is +always difficult to decide what to cook each day, so it would be nice +if we could ask @command{recsel} to pick up a random recipe. This can +be achieved using the @code{-m} (@code{--random}) command line option +of @command{recsel}: + +@example +$ recsel -m 1 recipes.rec +Title: Curry chicken +Ingredient: A whole chicken +Ingredient: Curry +Preparation: ... +@end example + +@noindent If we need two recipes, because we will be cooking at +both lunch and dinner, we can pass a different number to @code{-m}: + +@example +$ recsel -m 2 recipes.rec +Title: Fabada Asturiana +Ingredient: 300 gr of fabes. +Ingredient: Chorizo +Ingredient: Morcilla +Preparation: ... + +Title: Pasta with ragu +Ingredient: 500 gr of spaghetti. +Ingredient: 2 tomatoes. +Ingredient: Minced meat. +Preparation: ... +@end example + +@noindent +The algorithm used to implement @code{-m} guarantees that +you will never get multiple instances of the same record. This means +that if a record set has @var{n} records and you ask for @var{n} +random records, you will get all the records in a random order. + +@node Selection Expressions +@section Selection Expressions + +@cindex selection expressions +@dfn{Selection expressions}, also known as ``sexes'' in recutils +jargon, are infix expressions that can be applied to a record. +A ``sex'' is a predicate which selects a subset of records within a recfile. +They can be simple expressions involving just one operator and a pair of +operands, or complex compound expressions with parenthetical sub-expressions +and many operators and operands. +One of their most common uses is to examine records matching a particular +set of conditions. + +@menu +* Selecting by predicate:: Selecting records which satisfy conditions. +* SEX Operands:: Literal values, fields and sub-expressions. +* SEX Operators:: Arithmetic, logical and other operators. +* SEX Evaluation:: Selection expressions are like generators. +@end menu + +@node Selecting by predicate +@subsection Selecting by predicate +@cindex selecting records +@cindex looking up data +@cindex retrieving data +Consider the example recfile @file{acquaintances.rec} introduced earlier. +It contains names of people along with their respective ages. +Suppose we want to get a list of the names of all the children. +It would not be easy to do this using @command{grep}. +Neither would it, for any reasonably large recfile, be feasible to search +manually for the children. +Fortunately the @command{recsel} command provides an easy way to do +such a lookup: +@cindex @command{recsel} +@example +$ recsel -e "Age < 18" -P Name acquaintances.rec +Bart Simpson +Adrian Mole +@end example + +@noindent Let us look at each of the arguments to @command{recsel} in turn. +Firstly we have @code{-e} which tells @command{recsel} to lookup records +matching the expression @code{Age < 18} --- in other words all those people +whose ages are less than 18. +@cindex selection expressions +This is an example of a @dfn{selection expression}. +In this case it is a simple test, but it can be as complex as needed. + +Next, there is @code{-P} which tells @command{recsel} to print out the value of +the @code{Name} field --- because we want just the name, not the entire record. +The final argument is the name of the file from whence the records are +to come: @file{acquaintances.rec}. + +Rather than explicitly storing ages in the recfile, a more realistic example +might have the date of birth instead +(otherwise it would be necessary to update the people's ages in the +recfile on every birthday). + +@example +# Date of Birth +%type: Dob date + +Name: Alfred Nebel +Dob: 20 April 2010 +Email: alf@@example.com + +Name: Bertram Worcester +Dob: 3 January 1966 +Email: bert@@example.com + +Name: Charles Spencer +Dob: 4 July 1997 +Email: charlie@@example.com + +Name: Dirk Hogart +Dob: 29 June 1945 +Email: dirk@@example.com + +Name: Ernest Wright +Dob: 26 April 1978 +Email: ernie@@example.com +@end example + +@noindent Now we can achieve a similar result as before, by looking up +the names of all those people who were born after a particular date: +@example +$ recfix acquaintances.rec +$ recsel -e "Dob >> '31 July 1994'" -p Name acquaintances.rec +Name: Alfred Nebel +Name: Charles Spencer +@end example + +@cindex date comparison +@noindent The @code{>>} operator means ``later than'', and is used +here to select a date of birth after 31st July 1994. +Note also that this example uses a lower case @code{-p} whereas the preceding example +used the upper case @code{-P}. The difference is that @code{-p} prints the field name +and field value, whereas @code{-P} prints just the value. + +@command{recsel} accepts more than one @code{-e} argument, +each introducing a selection expression, +in which case the records which satisfy all expressions are selected. +You can provide more than one field label to @code{-P} or @code{-p} in order to select +additional fields to be displayed. +For example, if you wanted to send an email to all children 14 to 18 +years of age, +and today's date were @w{1st August} 2012, then you could use the following command to get +the name and email address of all such children: + +@example +$ recfix acquaintances.rec +$ recsel -e "Dob >> '31 July 1994' && Dob << '01 August 1998'" \ + -p Name,Email acquaintances.rec +Name: Charles Spencer +Email: charlie@@example.com +@end example + +@noindent As you can see, there is only one such child in our record set. + +@cindex quotation marks +Note that the example command shown above contains both double quotes @code{"} and +single quotes @code{'}. +@cindex date comparison +The double quotes are interpreted by the shell (@eg{} @command{bash}) and +the single quotes are interpreted by @command{recsel}, defining a +string.

The field name is replaced by a string +containing the field value, to handle the possibility of records with +more than one field by that name. Examples: + +@example +Name +Email +long_field_name +@end example + +It is possible to use the role part of a field if it is not empty. +So, for example, if we are searching for the issues opened by +@samp{John Smith} in a database of issues we could write: + +@example +$ recsel -e "OpenedBy = 'John Smith'" +@end example + +@noindent +instead of using a full field name: + +@example +$ recsel -e "Hacker:Name:OpenedBy = 'John Smith'" +@end example + +When the name of a field appears in an expression, the expression is +applied to all the fields in the record featuring that name. So, for +example, the expression: + +@example +Email ~ "\\.org" +@end example + +@noindent +matches any record in which there is a field named @samp{Email} +whose value terminates in (the literal string) @samp{.org}. +If we are interested in the value of some specific email, we can specify +its relative position in the containing record by using @dfn{subscripts}. +@cindex subscripts, in selection expressions +Consider, for example: + +@example +Email[0] ~ "\\.org" +@end example + +@noindent +Will match for: + +@example +Name: Mr. Foo +Email: foo@@foo.org +Email: mr.foo@@foo.com +@end example + +@noindent +But not for: + +@example +Name: Mr. Foo +Email: mr.foo@@foo.com +Email: foo@@foo.org +@end example + +The regexp syntax supported in selection expressions is POSIX +EREs, with several GNU extensions. @xref{Regular Expressions}. + +@subsubsection Parenthesized Expressions +@cindex parentheses, in selection expressions. +Parenthesis characters (@code{(} and @code{)}) can be used to group +sub expressions in the usual way. + +@node SEX Operators +@subsection Operators + +@cindex operators, in selection expressions +The supported operators are arithmetic operators (addition, +subtraction, multiplication, division and modulus), logical operators, +string operators and field operators. + +@subsubsection Arithmetic Operators +@cindex arithmetic operators +@cindex operators, arithmetic operators + +Arithmetic operators for addition (@code{+}), subtraction (@code{-}), +multiplication (@code{*}), integer division (@code{/}) and modulus +(@code{%}) are supported with their usual meanings. + +These operators require either numeric operands or string operands +whose value can be interpreted as numbers (integer or real). + +@subsubsection Boolean Operators +@cindex boolean operators +@cindex operators, boolean operators + +The boolean operators @strong{and} (@code{&&}), @strong{or} +(@code{||}) and @strong{not} (@code{!})@: are supported with the same +semantics as their C counterparts. + +A compound boolean operator @code{=>} is also supported in order to +ease the elaboration of constraints in records: @code{A => B}, which +can be read as ``A implies B'', translates into @code{!A || (A && B)}. + +The boolean operators expect integer operands, and will try to convert +any string operand to an integer value. + +@subsubsection Comparison Operators + +@cindex operators, comparison operators +@cindex comparison +The compare operators @strong{less than} (@code{<}), @strong{greater +than} (@code{>}), @strong{less than or equal} (@code{<=}), +@strong{greater than or equal} (@code{>=}), @strong{equal} (@code{=}) +and @strong{unequal} (@code{!=}) are supported with their usual +meaning. + +Strings can be compared with the equality operator (@code{=}). + +The match operator (@code{~}) can be used to match a string with a +given regular expression (@pxref{Regular Expressions}). + +@subsubsection Date Comparison Operators +@cindex date comparison +The compare operators @strong{before} (@code{<<}), @strong{after} +(@code{>>}) and @strong{same time} (@code{==}) can be used with fields +and strings containing parseable dates. + +@xref{Date input formats}. + +@subsubsection Field Operators +@cindex field operators +@cindex counting occurrences of a field +Field counters are replaced by the number of occurrences of a field +with the given name in the record.

It can be zero if the record does not +have a field with that name. + +@subsubsection String Operators +@cindex string operators +@cindex operators, string operators +The string concatenation operator (@code{&}) can be used to +concatenate any number of strings and field values. + +@example +'foo' & Name & 'bar' +@end example + +@subsubsection Conditional Operator +@cindex conditional operator +@cindex operators, conditional operator +The ternary conditional operator can be used to select alternatives +based on the value of some expression: + +@example +expr1 ? expr2 : expr3 +@end example + +If @code{expr1} evaluates to true (@ie{} it is an integer or the string +representation of an integer and its value is not zero) then the +operator yields @code{expr2}. Otherwise it yields @code{expr3}. + +@node SEX Evaluation +@subsection Evaluation of Selection Expressions +@cindex evaluation, of selection expressions + +Given that: + +@itemize @minus +@item It is possible to refer to fields by name in selection expressions. +@item Records can have several fields with the same name. +@end itemize + +@noindent +It is clear that some backtracking mechanism is needed in the +evaluation of the selection expressions. For example, consider the +following expression that is deciding whether a ``registration'' in a +webpage should be rejected: + +@example +((Email ~ "foomail\.com") || (Age <= 18)) && !#Fixed +@end example + +The previous expression will be evaluated for every possible +permutation of the fields ``Email'', ``Age'' and ``Fixed'' present in +the record, until one of the combinations succeeds. At that point the +computation is interrupted. + +When used to decide whether a record matches some criteria, the goal +of a selection expression is to act as a boolean expression. In that +case the final value of the expression depends on both the type and +the value of the result launched by the top-most subexpression: + +@itemize @minus +@item If the result is an @b{integer}, the expression is true if its +value is not zero. +@item If the result is a @b{real}, or a @b{string}, the expression +evaluates to false. +@end itemize + +Sometimes a selection expression is used to compute a result instead +of a boolean. In that case the returned value is converted to a +string. This is used when replacing the slots in templates +(@pxref{Templates}). + +@node Field Expressions +@section Field Expressions + +@cindex field expressions +@cindex FEX + +@dfn{Field expressions} (also known as ``fexes'') are a way to select +fields of a record.

It is possible to +refer to a field occupying a given position. For example, consider +the following record: + +@example +Name: Mr. Foo +Email: foo@@foo.com +Email: foo@@foo.org +Email: mr.foo@@foo.org +@end example + +@noindent +We would select all the emails of the record with: + +@example +Email +@end example + +@noindent +The first email with: + +@example +Email[0] +@end example + +@noindent +The third email with: + +@example +Email[2] +@end example + +@noindent +The second and the third email with: + +@example +Email[1-2] +@end example + +And so on. It is possible to select the same field (or +range of fields) more than once just by repeating them in a field +expression. Thus, the field expression: + +@example +Email[0],Name,Email +@end example + +@noindent +will print the first email, the name, and then all the email fields +including the first one. + +@cindex aliasing, field name aliasing +It is possible to include a @dfn{rewrite rule} in an element of a +field expression, which specifies an alias for the selected fields: + +@example +@var{Field_Name}[@var{min}-@var{max}]:@var{Alias} +@end example + +@noindent +For example, the following field expression specifies an alias for the +fields named @code{Email} in a record: + +@example +Name,Email:ElectronicMail +@end example + +Since the rewrite rules only affect the fields selected in a single +element of the field expression, it is possible to define different +aliases to several fields having the same name but occupying different +positions: + +@example +Name,Email[0]:PrimaryEmail,Email[1]:SecondaryEmail +@end example + +@noindent +When that field expression is applied to the following record: + +@example +Name: Mr. Foo +Email: primary@@email.com +Email: secondary@@email.com +Email: other@@email.com +@end example + +@noindent +the result will be: + +@example +Name: Mr. Foo +PrimaryEmail: primary@@email.com +SecondaryEmail: secondary@@email.com +Email: other@@email.com +@end example + +It is possible to use the dot notation in order to refer to field and +sub-fields. This is mainly used in the context of joins, where new +fields are created having compound names such as @code{Foo_Bar}. A +reference to such a field can be done in the fex using dot notation +as follows: + +@example +Foo.Bar +@end example + +@node Sorted Output +@section Sorted Output + +@cindex @code{%sort} +@cindex sorting +This special field sets sorting criteria for the records +contained in a record set. Its usage is: + +@example +%sort: @var{field1} @var{field2} ... +@end example + +@noindent +Meaning that the desired order for the records will be determined by +the contents of the fields named in the @code{%sort} value. The +sorting is always done in ascending order, and there may be records +that lack the involved fields, @ie{} the sorting +fields need not be mandatory. + +It is an error to have more than one @code{%sort} field in the same +record descriptor, as only one field list can be used as sorting +criteria. + +Consider for example that we want to keep the records in our inventory +system ordered by entry date. We could achieve that by using the +following record descriptor in the database: + +@example +%rec: Item +%type: Date date +%sort: Date + +Id: 1 +Title: Staplers +Date: 10 February 2011 + +Id: 2 +Title: Ruler Pack 20 +Date: 2 March 2009 + +@dots{} +@end example + +@noindent +As you can see in the example above, the fact we use @code{%sort} in a +database does not mean that the database will be always physically +ordered. Unsorted record sets are not a data integrity +problem, and thus the diagnosis tools must not declare a recfile as ++invalid because of this. The utility @command{recfix} provides a way ++to physically order the fields in the file (@pxref{Invoking recfix}). + +On the other hand any program listing, presenting or processing data +extracted from the recfile must honor the @code{%sort} entry. For +example, when using the following @command{recsel} program in the +database above we would get the output sorted by date: + +@example +$ recsel inventory.rec +Id: 2 +Title: Ruler Pack 20 +Date: 2 March 2009 + +Id: 1 +Title: Staplers +Date: 10 February 2011 +@end example + +@cindex order of fields +@noindent +The sorting of the selected field depends on its type: + +@itemize @minus +@item Numeric fields (integers, ranges, reals) are numerically ordered. +@item Boolean fields are ordered considering that ``false'' values come first. +@item Dates are ordered chronologically. +@item Any other kind of field is ordered using a lexicographic order. +@end itemize + +It is possible to specify several fields as the sorting criteria. In +that case the records are sorted using a lexicographic order.

This is useful for writing shell scripts +or when there are complex data integrity rules stored in the file that +we want to be sure to preserve. + +The following sections discuss the usage of the recutils for altering +recfiles in the level of record: adding new records, deleting or +commenting them out, sorting them, @etc{} + +@menu +* Inserting Records:: Inserting data into recfiles. +* Deleting Records:: Removing data. +* Sorting Records:: Physical reordering of records. +@end menu + +@node Inserting Records +@section Inserting Records + +Adding new records to a recfile is pretty trivial: open it with your +text editor and just write down the fields comprising the records. +This is really the best way to add contents to a recfile containing +simple data.

The usage of @command{recins} is +very simple, and can be used both in the command line or called from +another program. The following subsections discuss several aspects of +using this utility. + +@menu +* Adding Records With recins:: Basics of the @command{recins} utility. +* Replacing Records With recins:: Substituting records in a file. +* Adding Anonymous Records:: Inserting or replacing records with no + type. +@end menu + +@node Adding Records With recins +@subsection Adding Records With recins + +Each invocation of @command{recins} adds one record to the targeted +database. The fields comprising the records are specified using pairs +of @code{-f} and @code{-v} command line arguments. For example, this +is how we would add the first entry to a previously empty contacts +database: + +@example +$ recins -f Name -v "Mr Foo" -f Email -v foo@@bar.baz contacts.rec +$ cat contacts.rec +Name: Mr. Foo +Email: foo@@bar.baz +@end example + +@noindent +If we invoke @command{recins} again on the same database we will be adding a +second record: + +@example +$ recins -f Name -v "Mr Bar" -f Email -v bar@@gnu.org contacts.rec +$ cat contacts.rec +Name: Mr. Foo +Email: foo@@bar.baz + +name: Mr. Bar +Email: bar@@gnu.org +@end example + +There is no limit on the number of @code{-f} @code{-v} pairs that can +be specified to @command{recins}, other than any limit on command line arguments +which may be imposed by the shell. + +The field values provided using @code{-v} are encoded to follow the +rec format conventions, including multi-line field values. +Consider the following example: + +@example +$ recins -f Name -v "Mr. Foo" -f Address -v ' +Foostrs. 19 +Frankfurt am Oder +Germany' contacts.rec +$ cat contacts.rec +Name: Mr. Foo +Address: ++ Foostrs. 19 ++ Frankfurt am Oder ++ Germany +@end example + +It is also possible to provide fields already encoded as rec data for +their addition, using the @code{-r} command line argument. This +argument can be intermixed with @code{-f} @code{-v}. + +@example +$ recins -f Name -v "Mr. Foo" -r "Email: foo@@bar.baz" contacts.rec +$ cat contacts.rec +Name: Mr. Foo +Email: foo@@bar.baz +@end example + +If the string passed to @code{-r} is not valid rec data then +@command{recins} will complain with an error and the operation will be +aborted. + +At this time, it is not possible to add new records +containing comments. + +@node Replacing Records With recins +@subsection Replacing Records With recins + +@command{recins} can also be used to replace existing records in a +database with a provided record. This is done by specifying some +criteria selecting the record (or records) to be replaced. + +Consider for example the following command applied to our contacts +database: + +@example +$ recins -e "Email = 'foo@@bar.baz'" -f Name -v "Mr. Foo" \ + -f Email -v "new@@bar.baz" contacts.rec +@end example + +@noindent +The contact featuring an email @code{foo@@bar.baz} gets replaced with +the following record: + +@example +Name: Mr. Foo +Email: new@@bar.baz +@end example + +The records to be replaced can also be specified by index, or a +range of indexes. For example, the following command replaces the +first, second and third records in a database with dummy records: + +@example +$ recins -n 0,1-2 -f Dummy -v XXX foo.rec +$ cat foo.rec +Dummy: XXX + +Dummy: XXX + +Dummy: XXX + +... Other records ... +@end example + +@node Adding Anonymous Records +@subsection Adding Anonymous Records + +In a previous chapter we noted that @command{recsel} interprets the +absence of a @command{-t} argument depending on the actual contents of +the file. If the recfile contains records of just one type the +command assumes that the user is referring to these records. + +@command{recins} does not follow this convention, and the absence of +an explicit type always means to insert (or replace) an anonymous +record. Consider for example the following database: + +@example +%rec: Marks +%type: Class enum A B C + +Name: Alfred +Class: A + +Name: Bertram +Class: B +@end example + +@noindent +If we want to insert a new mark we have to specify the type explicitly +using @command{-t}: + +@example +$ cat marks.rec | recins -t Marks -f Name -v Xavier -f Class -v C +%rec: Marks +%type: Class enum A B C + +Name: Alfred +Class: A + +Name: Bertram +Class: B + +Name: Xavier +Class: C +@end example + +@noindent +If we forget to specify the type then an anonymous record is created +instead: + +@example +$ cat marks.rec | recins -f Name -v Xavier -f Class -v C +Name: Xavier +Class: C + +%rec: Marks +%type: Class enum A B C + +Name: Alfred +Class: A + +Name: Bertram +Class: B +@end example + +@node Deleting Records +@section Deleting Records +@cindex deleting records + +Just as @code{recins} inserts records, the utility @code{recdel} deletes them. +Consider the following recfile @file{stock.rec}: +@example +%rec: Item +%type: Expiry date +%sort: Title + +Title: First Aid Kit +Expiry: 2 May 2009 + +Title: Emergency Rations +Expiry: 10 August 2009 + +Title: Life raft +Expiry: 2 March 2009 +@end example + +Suppose we wanted to delete all items +with an @code{Expiry} value before a certain date, we could do this with the following command: + +@example +$ recdel -t Item -e 'Expiry << "5/12/2009"' stock.rec +@end example +@noindent +After running this command, only one record will remain in the file +(@viz{} the one titled `Emergency Rations') because all the others have expiry dates +prior to 12 May 2009. +@footnote{`5/12/2009' means the 12th day of May 2009, @emph{not} the fifth day of December, +even if your @env{LC_TIME} environment variable has been set to suggest otherwise.} +The @command{-t} option can be omitted if, and only if, there is no @code{%rec} field +in the recfile. + +@command{recdel} tries to warn you if you attempt to perform a delete operation +which it deems to be too pervasive. In such cases, it will refuse to run, +unless you give the @command{--force} flag. +However, you should not rely upon @command{recdel} to protect you, because it cannot +always correctly guess that you might be deleting more records than intended. +For this reason, it may be wise to use the @command{-c} flag, which causes +the relevant records to be commented out, rather than deleted.

In this chapter some typical usage +examples are discussed. As with @command{recdel}, @command{recset} if +used erroneously has the potential to make very pervasive changes, +which could result in a large loss of data.

The syntax is: + +@example +%typedef: @var{type_name} @var{type_description} +@end example + +@noindent +Where @var{type_name} is the name of the new type, and +@var{type_description} a description which varies depending of the +kind of type. +@cindex @code{range}, type description +For example, this is how a type @code{Age_t} could +be defined as numbers in the range @code{0..120}: + +@example +%typedef: Age_t range 0 120 +@end example + +@noindent +Type names are identifiers having the following syntax: + +@example +[a-zA-Z][a-zA-Z0-9_]* +@end example + +@noindent +Even though any identifier with that syntax could be used for types, +it is a good idea to consistently follow some convention to help +distinguishing type names from field names. For example, the +@code{_t} suffix could be used for types. + +A type can be declared to be an alias for another type. The syntax +is: + +@example +%typedef: @var{type_name} @var{other_type_name} +@end example + +@noindent +Where @var{type_name} is declared to be a synonym of +@var{other_type_name}. This is useful to avoid duplicated type +descriptions. For example, consider the following example: + +@example +%typedef: Id_t int +%typedef: Item_t Id_t +%typedef: Transaction_t Id_t +@end example + +@noindent +Both @code{Item_t} and @code{Transaction_t} are aliases for the type +@code{Id_t}. Which is in turn an alias for the type @code{int}. + So, they are both numeric identifiers. + +The order of the @code{%typedef} fields is not relevant. In +particular, a type definition can forward-reference another type that is defined +subsequently. The previous example could have been written as: + +@example +%typedef: Item_t Id_t +%typedef: Transaction_t Id_t +%typedef: Id_t int +@end example + +@noindent +@cindex integrity problems +Integrity check will complain if undefined types are referenced. As well as when any aliases up referencing back (looping back +directly or indirectly) in type declarations. For +example, the following set of declarations contains a loop. +Thus, it's invalid: + +@example +%typedef: A_t B_t +%typedef: B_t C_t +%typedef: C_t A_t +@end example + +@noindent +The scope of a type is the record descriptor where it is defined. + +@node Types and Fields +@section Types and Fields + +@cindex @code{%type} +@cindex @code{%typedef} + +@cindex types +@cindex field types, +Fields can be declared to have a given type by using the @code{%type} +special field in a record descriptor. The synopsis is: + +@example +%type: @var{field_list} @var{type_name_or_description} +@end example + +@noindent +Where @var{field_list} is a list of field names separated by commas. +@var{type_name_or_description} can be either a type name which has +been previously declared using @code{%typedef}, or a type description. +Type names are useful when several fields are declared to be of the +same type: + +@example +%typedef: Id_t int +%type: Id Id_t +%type: Product Id_t +@end example + +@cindex anonymous types +@noindent +Anonymous types can be specified by writing a type description instead +of a type name. They help to avoid superfluous type declarations in +the common case where a type is used by just one field. A record +containing a single @code{Id} field, for example, can be defined +without having to use a @code{%typedef} in the following way: + +@example +%rec: Task +%type: Id int +@end example + +@node Scalar Field Types +@section Scalar Field Types + +The rec format supports the declaration of fields of the following +scalar types: integer numbers, ranges and real numbers. + +@cindex integers +Signed @dfn{integers} are supported by using the @code{int} +declaration: + +@example +%typedef: Id_t int +@end example + +@cindex hexadecimal +@cindex octal +@noindent +Given the declaration above, fields of type @code{Id_t} must +contain integers, and they may be negative. Hexadecimal values can be written +using the @code{0x} prefix, and octal values using an extra +@code{0}. Valid examples are: + +@example +%type: Id Id_t + +Id: 100 +Id: -23 +Id: -0xFF +Id: 020 +@end example + +@cindex ranges +@noindent +Sometimes it is desirable to reduce the @dfn{range} of integers allowed in a +field. This can be achieved by using a range type declaration: + +@example +%typedef: Interrupt_t range 0 15 +@end example + +@noindent +Note that it is possible to omit the minimum index in ranges. In that +case it is implicitly zero: + +@example +%typedef: Interrupt_t range 15 +@end example + +@noindent +It is possible to use the keywords @code{MIN} and @code{MAX} instead +of a numeral literal in one or both of the points conforming the +range. They mean the minimum and the maximum integer value supported +by the implementation respectively. See the following examples: + +@example +%typedef: Negative range MIN -1 +%typedef: Positive range 0 MAX +%typedef: AnyInt range MIN MAX +%typedef: Impossible range MAX MIN +@end example + +@noindent +Hexadecimal and octal numbers can be used to specify the limits in a +range. This helps to define scalar types whose natural base is not +ten, like for example: + +@example +%typedef: Address_t range 0x0000 0xFFFF +%typedef: Perms_t range 755 +@end example + +@cindex reals +@cindex fractions +@cindex floating point numbers +@noindent +@dfn{Real} number fields can be declared with the @code{real} type +specifier. +A wide range of real numbers can be represented this way, only limited +by the underlying floating point representation. +@cindex decimal separator +@cindex locale +The decimal separator is always the dot (@code{.}) character regardless +of the locale setting. +For example: + +@example +%typedef: Longitude_t real +@end example + +@noindent +Examples of fields of type real: + +@example +%rec: Rectangle +%typedef: Longitude_t real +%type: Width Longitude_t +%type: Height Longitude_t + +Width: 25.01 +Height: 10 +@end example + + +@node String Field Types +@section String Field Types + +@cindex strings +The @code{line} field type specifier can be used to restrict the value +of a field to a single line, @ie{} no newline characters are allowed. +For example, a type for proper names could be declared as: + +@example +%typedef: Name_t line +@end example + +@noindent +Examples of fields of type line: + +@cindex multiline field values +@example +Name: Mr. Foo Bar +Name: Mrs. Bar Baz +Name: This is ++ invalid +@end example + +@cindex field size +@cindex size, field size +@cindex @code{size}, type description + +@noindent +Sometimes it is the maximum size of the field value that shall be +restricted. The @code{size} field type specifier can be used to +define the maximum number of characters a field value can have. For +example, if we were collecting input that will get written in a +paper-based forms system allowing up to 25 characters width entries, +we could declare the entries as: + +@example +%typedef: Address_t size 25 +@end example + +@noindent +Note that hexadecimal and octal integer constants can also be used to +specify field sizes: + +@example +%typedef: Address_t size 0x18 +@end example + +@cindex restricting values of fields +@noindent +Arbitrary restrictions can be defined by using regular expressions. +@cindex @code{regexp}, type description +The @dfn{regexp} field type specifier introduces an ERE (extended +regular expression) that will be matched against fields having that +name. The synopsis is: + +@example +%typedef: @var{type_name} regexp /@var{re}/ +@end example + +@noindent +where @var{re} is the regular expression to match. + +For example, consider the @code{Id_t} type designed to represent +the encoding of the identifier of ID cards in some country: + +@example +%typedef: Id_t regexp /[0-9]@{9@}[a-zA-Z]/ +@end example + +@noindent +Examples of fields of type @code{Id_t} are: + +@example +IDCard: 123456789Z +IDCard: invalid id card +@end example + +@noindent +Note that the slashes delimiting the @var{re} can be replaced with +any other character that is not itself used as part of the regexp. +That is useful in some cases such as: + +@example +%typedef: Path_t regexp |(/[^/]/?)+| +@end example + +@noindent +The regexp flavor supported in recfiles are the POSIX EREs plus +several GNU extensions. @xref{Regular Expressions}. + +@node Enumerated Field Types +@section Enumerated Field Types + +@cindex enumerated types +Fields of this type contain symbols taken from an enumeration. + +The type is described by writing the sequence of symbols comprising +the enumeration. Enumeration symbols are strings described by the +following regexp: + +@example +[a-zA-Z0-9][a-zA-Z0-9_-]* +@end example + +@noindent +The symbols are separated by blank characters (including newlines). +For example: + +@cindex day of week +@example +%typedef: Status_t enum NEW STARTED DONE CLOSED +%typedef: Day_t enum Monday Tuesday Wednesday Thursday Friday ++ Saturday Sunday +@end example + +@noindent +@cindex comments, in enumerated types +It is possible to insert comments when describing an enum type. The +comments are delimited by parenthesis pairs. The contents of the +comments can be any character but parentheses.

The synopsis is: + +@example +%typedef: @var{type_name} date +@end example + +@cindex locale +@cindex time zone correction +@noindent +There are many permitted date formats, described in detail later in this manual (@pxref{Date input formats}). +Of particular note are the following: +@itemize @minus +@item Dates and times read from recfiles are not affected by the +locale or the timezone. This means that the @env{LC_TIME} and the +@env{TZ} environment variables are ignored. +If you wish, for example, to specify a time which must be interpreted as UTC, you +must explicitly append the time zone correction: @eg{} @samp{2001-1-10 12:09Z}. +@item The field value `1/10/2001' means January 10, 2001, @strong{not} October 1, 2001. +@item Relative times and dates (such as `1 day ago') are permitted but are not + particularly useful. +@end itemize + +@node Other Field Types +@section Other Field Types + +@cindex email +The @dfn{Email} field type specifier is used to declare electronic +addresses. The synopsis is: + +@example +%typedef: Email_t email +@end example + +@noindent +Sometimes it is useful to make fields to store field names. For that +purpose the @dfn{Field} field type specifier is supported.

The synopsis is: + +@example +%typedef: Id_t uuid +@end example + +@noindent +The format of the uuids is specified as 32 hexadecimal digits, +displayed in five groups separated by hyphens. For example: + +@example +550e8400-e29b-41d4-a716-446655440000 +@end example + +@noindent +@cindex foreign key +There is one other possible field type, @viz{} a foreign key. +The following example +defines the type @code{Maintainer_t} to be of type ``record @code{Hacker}''; +in other words, a foreign key referring to a record in the @code{Hacker} record set. +@example +%typedef: Maintainer_t rec Hacker +@end example +@noindent This essentially means that the values +to be stored in fields of type @code{Maintainer_t} are of whatever +type is defined for the primary key of the @code{Hacker} record set. +Why this is useful is discussed later. @xref{Queries which Join Records}. + +@node Constraints on Record Sets +@chapter Constraints on Record Sets + +The records in a recfile are by default not restricted to any particular +structure +except that they must contain one or more fields and optional comments. +This provides the format with huge expressive power; +but in many cases, it is also desirable to impose some restrictions in +order to reflect some of the properties of the data stored in the +database. It is also useful in order to preserve data integrity and +thus avoid data corruption. + +The following sections describe the usage of some predefined special +fields whose purpose is to impose this kind of restriction in the +structure of the records. + +@menu +* Mandatory Fields:: Requiring the presence of fields. +* Prohibited Fields:: Forbidding the presence of fields. +* Allowed Fields:: Restricting the presence of fields. +* Keys and Unique Fields:: Fields characterizing records. +* Singular Fields:: Fields with unique contents. +* Size Constraints:: Constraints on the number of records in a set. +* Arbitrary Constraints:: Constraints records must comply with. +@end menu + + +@node Mandatory Fields +@section Mandatory Fields + +@cindex @code{%mandatory} +@cindex mandatory fields +@cindex requiring certain fields in records +@cindex compulsory fields + +Sometimes, you want to make sure that @emph{every} record of a particular type +contains certain fields. +To do this, use the special field @code{%mandatory}. +The usage is: + +@example +%mandatory: @var{field1} @var{field2} @dots{} @var{fieldN} +@end example +@noindent +The field names are separated by one or more +blank characters. + +@cindex field, compulsory fields +@cindex field, mandatory fields +The fields listed in a @code{%mandatory} entry are +non-optional; @ie{} at least one field with this name shall be present +in any record of this kind. +@cindex integrity problems +Records violating this restriction are +invalid and a checking tool will report the situation as +a data integrity failure. + +Consider for example an ``address book'' database where each record +stores the information associated with a contact. The records will be +heterogeneous, in the sense they won't all contain exactly the same +fields: the contact of an Internet shop will probably have a +@code{URL} field, while the entry for our grandmother probably won't. +We still want to make sure that every entry has a field with the name +of the contact. In this case, we could use @code{%mandatory} as +follows: + +@example +%rec: Contact +%mandatory: Name + +Name: Granny +Phone: +12 23456677 + +Name: Yoyodyne Corp. +Email: sales@@yoyod.com +Phone: +98 43434433 +@end example + +A word of caution, however: In many situations, especially in day to day social +interaction, it is common to find that certain information is simply unavailable. +For example, although every person has a date of birth, some people will refuse +to provide that information. + +It is probably wise therefore to avoid stipulating a field as mandatory, unless it is +essential to the enterprise. +Otherwise, +a data entry clerk faced with this situation will have to make the choice between +dropping the entry entirely or entering some fake data to keep the system happy. + + +@node Prohibited Fields +@section Prohibited Fields + +@cindex @code{%prohibit} +@cindex restricting fields from records +@cindex field, forbidden fields +@cindex prohibited fields + +The inverse of @code{%mandatory} is @code{%prohibit}. +Prohibited fields may not occur in @emph{any} record of the given type. +The usage is: + +@example +%prohibit: @var{field1} @var{field2} @dots{} @var{fieldN} +@end example +@noindent The field names are separated by one or more blank characters. + +@noindent +Fields listed in a @code{%prohibit} entry are +forbidden; @ie{} no field with this name should be present +in any record of this kind. +Again, records violating this restriction +are invalid. + +@noindent +Several @code{%prohibit} fields can appear in +the same record descriptor. +The set of prohibited fields +is the union of all the entries. +For example, in the following +database both @code{Id} and @code{id} are prohibited: + +@example +%rec: Entry +%prohibit: Id +%prohibit: id +@end example + +One possible use case for prohibited fields arises +when some field name is reserved for some future +use. +For example, if we were organizing a sports competition, we would want +competitors to register before the event. +However a competitor's @code{result} should not and cannot be entered +before the competition takes place. +Initially then, we would change the record +descriptor as follows: + +@example +%rec: Contact +%mandatory: Name +%prohibit: result +@end example +@noindent +At the start of the event, the @code{%prohibit} line can be deleted, to +allow results to be entered. + +@node Allowed Fields +@section Allowed Fields + +@cindex @code{%allowed} +@cindex restricting fields from records +@cindex field, allowed fields +@cindex allowed fields + +In some cases we know the set of fields that may appear in the records +of a given type, even if they are not mandatory. The @code{%allowed} +special field is used to specify this restriction. The usage is: + +@example +%allowed: @var{field1} @var{field2} @dots{} @var{fieldN} +@end example +@noindent The field names are separated by one or more blank +chracters. + +@noindent +If there are more or one @code{%allowed} fields in a record +descriptor, all fields of all the records in the record set must be in +the union of @code{%allowed}, @code{%mandatory} and @code{%key}. +Otherwise an integrity error is raised. + +@noindent +Several @code{%allowed} fields can appear in the same record +descriptor. The set of allowed fields is the union of all the +entries. + +@node Keys and Unique Fields +@section Keys and Unique Fields + +@cindex @code{%unique} +@cindex @code{%key} +The @code{%unique} and @code{%key} special fields are +used to avoid several instances of the +same field in a record, and to implement keys in record sets. +Their usage is: + +@example +%unique: @var{field1} @var{field2} @dots{} @var{fieldN} +%key: @var{field} +@end example + +@noindent +The field names are separated by one or more blank characters. + +@cindex unique fields +Normally it is permitted for a record to contain two or more fields of +the same name. +The @code{%unique} special field revokes this permissiveness. +A field declared ``unique'' cannot appear more than once in a single record. + +For example, an entry in an address book database could contain an +@code{Age} field. It does not make sense for a single person to be of +several ages. So, a field could be declared as ``unique'' in the +corresponding record descriptor as follows: + +@example +%rec: Contact +%mandatory: Name +%unique: Age +@end example + +@noindent +Several @code{%unique} fields can appear in the same record +descriptor. The set of unique fields is the union of all the entries. + +@cindex primary key +@code{%key} makes the referenced field the primary key of the record +set. +The primary key behaves as if both @code{%unique} and +@code{%mandatory} had been specified for that field. +Additionally, there is further restriction, @viz{} +a given value of a primary key field may appear no more than once within a +record set. + +Consider for example a database of items in stock. Each item is +identified by a numerical @code{Id} field. No item may have more than +one @code{Id}, and no items may exist without an associated +@code{Id}. Additionally, no two items may share the same @code{Id}. +This common situation can be implementing by declaring @code{Id} as +the key in the record descriptor: + +@example +%rec: Item +%key: Id +%mandatory: Title + +Id: 1 +Title: Box + +Id: 2 +Title: Sticker big +@end example + +@noindent +It would not make sense to have several primary keys in a record set. +Thus, it is not allowed to have several @code{%key} fields in the +same record descriptor. +It is also forbidden for two items to share the same `Id' value. +@cindex integrity problems +Both of these situations would be data integrity +violations, and will be reported by a checking tool. + +Elsewhere, we discuss how primary keys can be used to link one record set to +another using primary keys together with foreign keys. @xref{Queries which Join Records}. + +@node Singular Fields +@section Singular Fields + +Sometimes we require certain fields with a given name to not appear in +a record set featuring the same contents, but we don't want (or we +can't) declare such fields as the key of the record set. + +In these circumstances we can use @dfn{singular fields}, which are +declared as such in the record descriptor using the @code{%singular} +special field: + +@example +%singular: @var{field} +@end example + +@node Size Constraints +@section Size Constraints + +@cindex @code{%size} +@cindex size, record size +@cindex record size +Sometimes it is desirable to place constraints on entire records. +This can be done with the @code{%size} special field which is used to limit the +number of records in a record set. Its usage is: + +@example +%size: [@var{relational_operator}] @var{number} +@end example + +@noindent +If no operator is specified then @var{number} is interpreted as the +exact number of records of this type. The number can be any integer +literal, including hexadecimal and octal constants. For example: + +@example +%rec: Day +%size: 7 +%type: Name enum ++ Monday Tuesday Wednesday Thursday Friday ++ Saturday Sunday +%doc: There should be exactly 7 days. +@end example + +@cindex operators +The optional @var{relational_operator} shall be one of @code{<}, +@code{<=}, @code{>} and @code{>=}@. For example: + +@example +%rec: Item +%key: Id +%size: <= 100 +%doc: We have at most 100 different articles. +@end example + +It is valid to specify a size of @code{0}, meaning that no records of +this type shall exist in the file. + +Only one @code{%size} field shall appear in a record descriptor. + + +@node Arbitrary Constraints +@section Arbitrary Constraints +@cindex @code{%constraint} +@cindex restricting values of fields + +Occasionally, @code{%mandatory}, @code{%prohibit} and @code{%size} are just not flexible enough. +We might, for instance, want to ensure that @emph{if} a field is present, +then it must have a certain relationship to other fields. +Or we might want to stipulate that under certain conditions only, a record contains +a particular field. + +To this end, recutils provides a way for arbitrary field constraints to be defined. +These permit restrictions on the presence and/or value of fields, based upon the value or +presence of other fields within that record. +This is done using the @code{%constraint} special field. +Its usage is: + +@example +%constraint: @var{expr} +@end example + +@noindent +where @var{expr} is a selection expression (@pxref{Selection Expressions}). +When a constraint is +present in a record set it means that all the records of that type +must satisfy the selection expression, @ie{} the evaluation of the +expression with the record returns 1. Otherwise an integrity error is +raised. +@cindex integrity problems + + +Consider for example a record type @code{Task} featuring two fields of +type date called @code{Start} and @code{End}.

The synopsis of the usage of the field is +the following: + +@example +%rec: @var{type} [@var{url_or_file}] +@end example + +@noindent +@var{type} is the name of the kind of records described by the +descriptor. It is mandatory to specify it, and it follows the same +lexical conventions used by field names. @xref{Fields}. +There is a non-enforced convention to use singular nouns, because the +name makes reference to the type of a single entity, even if it +applies to all the records contained in the record set. For example, +the following record set contains transactions, and the type specified +in the record descriptor is @code{Transaction}. + +@example +%rec: Transaction + +Id: 10 +Title: House rent + +Id: 11 +Title: Loan +@end example + +@noindent +Only one @code{%rec} field should be in a record descriptor. If +there are more it is an integrity violation. It is highly +recommended (but not enforced) to place this field in the first +position of the record descriptor. + +Sometimes it is convenient to store records of the same type in +different files. +@cindex integrity problems +The duplication of record descriptors in this case would surely lead to +consistency problems. +A possible solution would +be to keep the record descriptor in a separated file and then include +it in any operation by using pipes. For example: + +@example +$ cat descriptor.rec data.rec | recsel @dots{} +@end example + +@cindex external descriptor +@cindex descriptor, external descriptor +@noindent +For those cases it is more convenient to use a @dfn{external +descriptor}. External descriptors can be built appending a file path +to the @code{%rec} field value, like: + +@example +%rec: FSD_Entry /path/to/file.rec +@end example + +The previous example indicates that a record descriptor describing the +@code{FSD_Entry} records shall be read from the file +@file{/path/to/file.rec}. A record descriptor for @code{FSD_Entry} +may not exist in the external file. Both relative and absolute paths +can be specified there. + +@cindex URL +@cindex remote descriptors +URLs can be used as sources for external descriptors as well. In that +case we talk about @dfn{remote descriptors}.

These are so called +because they accept a record set and a field name as inputs and +generate a single result. Usually this result is numerical. + +The supported aggregate functions are the following: + +@table @code +@item Count(FIELD) +Counts the number of occurrences of a field. +@item Avg(FIELD) +Calculates the average (mean) of the numerical values of a field. +@item Sum(FIELD) +Calculates the sum of the numerical values of a field. +@item Min(FIELD) +Calculates the minimum numerical value of a field. +@item Max(FIELD) +Calculates the maximum numerical value of a field. +@end table + +The aggregate functions are to be invoked in the field expressions in +@command{recsel}. By default they are applied to the totality of the +records in a record set. For example, using the items database from +the previous section, we can do calculations as in the following examples. + +The SQL aggregate functions can be applied to the totality of the +tuples in the relation. For example, using the @code{Count} aggregate +function we can calculate the number of fields named @code{Category} +present in the record set as follows: + +@example +$ recsel -p "Count(Category)" items.rec +Count_Category: 5 +@end example + +@noindent +The result is a field whose name is derived from the function name and +the field passed as its parameter, separated by an underline. This +name scheme probably suffices for most purposes, but it is always +possible to use a rewrite rule to obtain something different: + +@example +$ recsel -p "Count(Category):NumCategories" items.rec +NumCategories: 5 +@end example + +@noindent +You can use different letter case in writing the name of the aggregate, and +this will be reflected in the field name: + +@example +$ recsel -p "CoUnT(Category)" items.rec +CoUnT_Category: 5 +@end example + +@noindent +It is possible to use more than one aggregate function in the field +expression. Suppose we are also interested in the average price of +the items we sell. We can use the @code{Avg} aggregate: + +@example +$ recsel -p "Count(Category),Avg(Price)" items.rec +Count_Category: 5 +Avg_Price: 4.240000 +@end example + +@noindent +Now let's add a field along with an aggregate function to the field +expression and see what we get: + +@example +$ recsel -p "Type,Avg(Price)" items.rec +Type: EC Car +Avg_Price: 12.200000 + +Type: Terria +Avg_Price: 0.600000 + +Type: Typex +Avg_Price: 1.200000 + +Type: Notebook +Avg_Price: 1 + +Type: Sexy Puzzle +Avg_Price: 6.200000 +@end example + +@noindent +We get five records! The reason is that when @emph{only} aggregate +functions are part of the field expression, they are applied to the single +record that would result from concatenating all the records in the record +set together. However, when a regular field appears in the field +expression the aggregate functions are applied to the individual +records. This is still useful in some cases, such as a database of +maintainers: + +@example +Name: Jose E. Marchesi +Email: jemarch@@gnu.org +Email: jemarch@@es.gnu.org + +Name: Luca Saiu +Email: positron@@gnu.org +@end example + +@noindent +Lets see how many emails each maintainer has: + +@example +$ recsel -p "Name,Count(Email)" maintainers.rec +Name: Jose E. Marchesi +Count_Email: 2 + +Name: Luca Saiu +Count_Email: 1 +@end example + +@noindent +Aggregate functions are most useful when we combine them with +grouping. This is when we are interested in some property of a subset +of the records in the database. For example, the average prices of +each item category stored in the database can be obtained by +executing: + +@example +$ recsel -p "Category,Avg(Price)" -G Category items.rec +Category: Food +Avg_Price: 0.600000 + +Category: Office +Avg_Price: 1.100000 + +Category: Toy +Avg_Price: 9.200000 +@end example + +@noindent +If we were interested in the actual prices that result in each average +we can do: + +@example +$ recsel -p "Category,Price,Avg(Price)" -G Category items.rec +Category: Food +Price: 0.60 +Avg_Price: 0.600000 + +Category: Office +Price: 1.20 +Price: 1.00 +Avg_Price: 1.100000 + +Category: Toy +Price: 12.2 +Price: 6.20 +Avg_Price: 9.200000 +@end example + +@node Queries which Join Records +@chapter Queries which Join Records + +Suppose you wanted to add the residential address of the people in +the @file{acquaintances.rec} file from +@ref{Simple Selections}. + + +One way to do this is as follows: +@example +%type: Dob date + +Name: Alfred Nebel +Dob: 20 April 2010 +Email: alf@@example.com +Address: 42 Abbeter Way, Inprooving, WORCS +Telephone: 01234 5676789 + +Name: Mandy Nebel +Dob: 21 February 1972 +Email: mandy@@example.com +Address: 42 Abbeter Way, Inprooving, WORCS +Telephone: 01234 5676789 + +Name: Bertram Nebel +Dob: 3 January 1966 +Email: bert@@example.com +Address: 42 Abbeter Way, Inprooving, WORCS +Telephone: 01234 5676789 + +Name: Charles Spencer +Dob: 4 July 1997 +Email: charlie@@example.com +Address: 2 Serpe Rise, Little Worning, SURREY +Telephone: 09876 5432109 + + Name: Dirk Spencer +Dob: 29 June 1945 +Email: dirk@@example.com +Address: 2 Serpe Rise, Little Worning, SURREY +Telephone: 09876 5432109 + +Name: Ernest Wright +Dob: 26 April 1978 +Email: ernie@@example.com +Address: 1 Wanter Rise, Greater Inncombe, BUCKS +@end example + + +This will work fine. +However you will notice that there are two addresses where more than one person +live (presumably they are members of the same family). +This has a number of disadvantages: +@itemize @minus +@item You have to type (or copy) the same information several times. +@item Should a family move house, then you would have to update the addresses (and telephone number) of all the family members. +@item A typing error in one of the addresses would lead an automatic query to erroneously suggest that the people lived at different addresses. +@item It unnecessarily increases the size of the recfile. +@end itemize + + +@menu +* Foreign Keys:: Referring to records from another records. +* Joining Records:: Performing cross-joins. +@end menu + + +@node Foreign Keys +@section Foreign Keys + +@cindex record sets +A better way would be to separate the addresses and people into different record sets. +@cindex duplication, avoiding +The first record set might look like this: + +@example +%rec: Person +%type: Dob date +%type: Abode rec Residence + + +Name: Alfred Nebel +Dob: 20 April 2010 +Email: alf@@example.com +Abode: 42AbbeterWay + +Name: Mandy Nebel +Dob: 21 February 1972 +Email: mandy@@example.com +Mobile: 0555 342123 +Abode: 42AbbeterWay + +Name: Bertram Nebel +Dob: 3 January 1966 +Email: bert@@example.com +Abode: 42AbbeterWay + +Name: Charles Spencer +Dob: 4 July 1997 +Email: charlie@@example.com +Abode: 2SerpeRise + +Name: Dirk Spencer +Dob: 29 June 1945 +Email: dirk@@example.com +Mobile: 0555 342123 +Abode: 2SerpeRise + +Name: Ernest Wright +Dob: 26 April 1978 +Abode: ChezGrampa + +@end example + +@noindent and the second (following in the same file), like this: + +@example + +%rec: Residence +%key: Id + +Address: 42 Abbeter Way, Inprooving, WORCS +Telephone: 01234 5676789 +Id: 42AbbeterWay + +Address: 2 Serpe Rise, Little Worning, SURREY +Telephone: 09876 5432109 +Id: 2SerpeRise + +Address: 1 Wanter Rise, Greater Inncombe, BUCKS +Id: ChezGrampa +@end example + +Here you can see that there are two record sets @viz{} @code{Person} +and @code{Residence}. +There are six people, but only three residences, because some residences +accommodate more than one person. +@cindex @code{%key} +Note also that the @code{Residence} descriptor has the entry @code{%key: Id} +whilst the @code{Person} descriptor has @code{%type: Abode rec Residence}. +@cindex foreign key +@cindex key, foreign key +@cindex @code{rec}, type description +This is because @code{Abode} is the foreign key which identifies the residence +where a person lives. + +@cindex readability +We could have declared the @code{Id} field as @code{%auto}.

In this way, it is self-evident by reading a @code{Person} +record where that person lives. +Yet since the @code{Id} field is declared using the @code{%key} special field +name, you can be sure that you don't accidentally reuse an existing key. + +@node Joining Records +@section Joining Records + +The above example has also added a new field to the @code{Person} record set +to contain that person's mobile phone number.

Was ``Helicopter'' in lower case or +upper case? + +@cindex primary key +@cindex key, primary key +@cindex @code{%key} +@cindex ID numbers +Thus it is quite common in databases to use some kind of numeric ``Id'' to +uniquely identify items like those ones, because numbers are +easy to increment and manipulate.

Other than its uniqueness, it is not important which number +is associated with which article. + +To ease the management of those Ids database systems use to provide a +facility called ``auto-counters''. Auto-counters can be implemented in +recfiles using the @code{%auto} directive in the record descriptor. +Its usage is: + +@example +%auto: @var{field1} @var{field2} @dots{} @var{fieldN} +@end example + +@noindent +The list of field names are separated by one or more blank characters. +There can be several @code{%auto} fields in the same record +descriptor, the effective list of auto-generated fields being the +union of all the entries. + +When @command{recins} inserts a new record in the recfile, it looks +for any declared auto field. If any of these fields are not provided +explicitly in the command line then @command{recins} generates them +along with the user-provided fields. Such auto fields are generated +at the beginning of the new records, in the same order they are found +in the @code{%auto} directives. + +For example, consider a @file{items.rec} database with an empty record +set: + +@example +%rec: Item +%key: Id +%auto: Id +%mandatory: Description +@end example + +@noindent +If we insert a new record and we do not specify an @code{Id} then it +will be generated automatically by @command{recins}: + +@example +$ recins -t Item -f Description -v 'recutils t-shirts' \ + -f Amount -v 200 \ + items.rec +$ cat items.rec +%rec: Item +%key: Id +%auto: Id +%mandatory: Description + +Id: 0 +Description: recutils t-shirts +Amount: 200 +@end example + +@noindent +The concrete effect of the @code{%auto} directive depends on the type +of the affected field.

We could +declare the @code{Id} field to be generated automatically: + +@example +%rec: Item +%key: Id +%type: Id int +%mandatory: Description +%auto: Id + +Id: 0 +Description: 2cm metal soldier WWII +Amount: 2111 +@end example + +@noindent +When the next new item is introduced in the database, @command{recins} +will note the @code{%auto}, and create a new @code{Id} field for the +new record with the next-biggest unused integer, since @code{Id} is +declared to be of type @code{int}. In this example, the new record +would have an Id of @code{1}. The database can still provide an +explicit Id for the new record. In that case the field is not +generated automatically. + +Note that if no explicit type is defined for an auto generated field +then it is assumed to be an integer. + +@node Unique Identifiers +@section Unique Identifiers +@cindex unique identifiers +@cindex uuid + +Universally Unique Identifiers, often abbreviated as UUIDs, can also +be auto-generated using recutils. Suppose you maintain a database +with events featuring the following record descriptor: + +@example +%rec: Event +%key: Id +%mandatory: Title Date +@end example + +@noindent +What would be appropriate to identify each event? We could use an +integer and declare it as auto-generated. After adding two events the +database would look like this: + +@example +%rec: Event +%key: Id +%mandatory: Title Date + +Id: 0 +Title: Team meeting +Date: 12-08-2013 + +Id: 1 +Title: Dave's birthday +Date: 20-12-2013 +@end example + +@noindent +However, suppose that we want to share our events with other people, +@ie{} to send them event records and to incorporate their records into +our own database. In this case the @code{Id}s would collide. A good +solution is to use @code{uuids} and declare them as @code{auto}: + +@example +%rec: Event +%key: Id +%type: Id uuid +%mandatory: Title Date + +Id: f81d4fae-7dec-11d0-a765-00a0c91e6bf6 +Title: Team meeting +Date: 12-08-2013 + +Id: f81d4fae-dc18-11d0-a765-a01328400a0c +Title: Dave's birthday +Date: 20-12-2013 +@end example + +@node Time-Stamps +@section Time-Stamps + +@cindex timestamps +Auto generated dates can be used to implement automatic timestamps. +Consider for example a ``Transfer'' record set registering bank +transfers.

When the information is retrieved from the database the +confidential fields are unencrypted if the correct password is +provided. Likewise, when information is inserted in the database the +confidential fields are encrypted with some given password. + +For example, consider a database of users of some service. For each +user we want to store a name, a login name, an email address and a +password. All this information is public with the obvious exception +of the password. Thus we declare the @code{Password} field as +confidential in the corresponding record descriptor: + +@example +%rec: Account +%type: Name line +%type: Login line +%type: Email email +%confidential: Password +@end example + +The rec format does not impose the usage of a specific encryption +algorithm, but requires that: + +@itemize @minus +@item The algorithm must be password-based. +@item The value of any encrypted field shall begin with the string +@samp{encrypted-} followed by the encrypted data. +@item The encrypted data must be encoded in some ASCII encoding such +as base64. +@end itemize + +The above rules assure that it is possible to determine whether a +given field is encrypted. For example, the following is an excerpt +from the account database described above. It contains an entry with +the password encrypted and another with the password unencrypted: + +@example +Name: Mr. Foo +Login: foo +Email: foo@@foo.com +Password: encrypted-AAABBBCCDDDEEEFFF + +Name: Mr. Bar +Login: bar +Email: bar@@bar.com +Password: secret +@end example + +Unencrypted confidential fields are a data integrity error, +and utilities like @code{recfix} will report it. +@cindex integrity problems +The same utility can +be used to ``fix'' the database by massively encrypting any +unencrypted field. + +Nothing prevents the usage of several passwords in the same database. +This allows the establishment of several level of securities or +security profiles. For example, we may want to store different +passwords for different online services: + +@example +%rec: Account +%confidential: WebPassword ShellPassword +@end example + +@noindent +We could then encrypt WebPassword entries using a password shared +among all the webmasters, and the ShellPassword entries with a more +restricted password available only to the administrator of the +machine. + +Note that since the utilities only accept to specify one password at a +time different passwords cannot be specified at decryption time. This +means that in the example above the administrator would need to run +@command{recsel} twice in order to decrypt all the encrypted data in +the recfile. + +The GNU recutils fully support encrypted fields. See the documentation +for @command{recsel}, @command{recins} and @command{recfix} for details on how +to operate on files containing confidential fields. + +@node Encrypting Files +@section Encrypting Files + +@command{recins} allows the insertion of encrypted fields in a +database. When the @option{-s} (@option{--password}) command line option is +specified in the command line any field declared as confidential in +the record descriptor will get encrypted using the given passphrase. +If the command is executed interactively and @option{-s} is not used +then the user is asked to provide a password using the terminal. For +example, the invocation: + +@example +$ recins -t Account -s mypassword -f Login -v foo -f Password \ + -v secret accounts.rec +@end example + +@noindent +will encrypt the value of the @code{Password} field with +@code{mypassword} as long as the field is declared as confidential. +(@pxref{Confidential Fields} for details on confidential fields). + +@command{recins} will issue a warning if a confidential field is +inserted in the database but no password was provided to encrypt it. +This is to avoid having unencrypted sensitive data in the recfiles. + +@node Decrypting Data +@section Decrypting Data + +The contents of confidential fields can be read using the +@option{-s} (@option{--password}) command line option to @command{recsel}. When +used, any selected record containing encrypted fields will try to +decrypt them with the given password. If the operation succeeds then +the output will include the unencrypted data. Otherwise the +ASCII-encoded encrypted data will be emitted. + +If @command{recsel} is invoked interactively and no password is +specified with @option{-s}, the user will be asked for a password in +case one is needed.

For example: + +@example +a: value +b: value +c: value + +a: value +b: value +c: value + +@dots{} +@end example + +In several respects records are more flexible than tables: + +@itemize @minus +@item Fields can appear in a different order in several records. +@item There can be several fields with the same name in a single record. +@item Records can differ in the number of fields. +@end itemize + +It is evident that records, such as those in recfiles, are a more +general structure than comma separated values. +This means that when converting from csv files to recfiles, certain +decisions need to be made. +The @code{rec2csv} utility (@pxref{Invoking rec2csv}) +implements an algorithm to deal with this problem +and generate a table that the user expects. + +The algorithm works as follows: + +@enumerate +@item +The utility first scans the specified +record set, building a list with the names that will become the table +header. + +@item +For each field, a header is added with the form: + +@example +FIELDNAME[_@var{n}] +@end example + +@noindent +where @var{n} is a number in the range @code{2..inf} and is the ``index'' of +the field in its containing record plus one. +For example, consider +the following record set: + +@example +a: a1 +b: b11 +b: b12 +c: c1 + +a: a2 +b: b2 +d: d2 +@end example + +The corresponding list of headers being: + +@example +a b b_2 c a b d +@end example + +@item +Then duplicates are removed: + +@example +a b b_2 c d +@end example + +@item +The resulting list of headers is then used to build the table in the +generated csv file. +@end enumerate + +In the above example the result would be + +@example +"a","b","b_2","c","d" +"a1","b11","b12","c1", +"a2","b2",,,"d2" +@end example + +As shown, missing fields are implemented as empty columns in the generated +csv. + +@node Importing MDB Files +@section Importing MDB Files + +Access files (@dfn{mdb files}) are collections of several relations, +also known as tables. Tables can be either @dfn{user tables} storing +user data, or @dfn{system tables} storing information such as forms, +queries or the relationships between the tables. + +It is possible to get a listing with the names of all tables stored in +a mdb file by calling @command{mdb2rec} in the following way: + +@example +$ mdb2rec -l sales.mdb +Customers +Products +Orders +@end example + +So @file{sales.mdb} stores user information in the tables Customers, +Products and Orders. If we want to include system tables in the +listing we can use the @samp{-s} command line option: + +@example +$ mdb2rec -s -l sales.mdb +MSysObjects +MSysACEs +MSysQueries +MSysRelationships +Customers +Products +Orders +@end example + +The tables with names starting with @command{MSys} are system tables. +The data stored in those tables is either not relevant to the recutils +user (used by the Access program to create forms and the like) or is +used in an indirect way by @command{mdb2rec} (such as the information +from MSysRelationships). + +Let's read some data from the @file{mdb} file.

As seen in the example, @command{mdb2rec} is +able to generate type information for the fields.

Marchesi + +@dots{} +@end example + +If no table is specified in the invocation to @command{mdb2rec} all +the tables in the file are processed, with the exception of the system +tables, which requires @samp{-s} to be used: + +@example +$ mdb2rec sales.mdb +%rec: Products +@dots{} + +%rec: Customers +@dots{} + +%rec: Orders +@dots{} +@end example + +@node Bash Builtins +@chapter Bash Builtins + +@cindex bash +@cindex interactive use +@cindex shell +The command-line utilities described in @ref{Invoking the Utilities} are +designed to be used interactively in the shell. +Together, and often +combined with the standard shell utilities, they provide a quite +complete user interface. +However, the user's experience can be greatly +improved by a closer integration between the recutils and the shell. +The following sections describe several extensions for @command{bash}, +the GNU shell (@pxref{Top,,, bash, The GNU Bourne-Again SHell}). +These extensions make the shell ``aware'' of the recutils. + +As with any bash built-in, help is available in the command line using +the @command{help} command. For example: + +@example +$ help readrec +@end example + +If you installed recutils using a binary package in a GNU/Linux +distribution, odds are that the built-in commands described in this +chapter are already available to you. Otherwise (you get a ``command +not found'' or similar error) you may have to register the built-in +commands with your bash. This is very easy using the @command{enable} +bash command. The registering command for readrec would be: + +@example +$ enable -f readrec.so readrec +@end example + +Note however that some systems require the full path to +@file{readrec.so} in order for this command to work. + + +@menu +* readrec:: Exporting the contents of records to the shell. +@end menu + +@node readrec +@section readrec + +The bash built-in @command{read}, when invoked with no options, +consumes one line from standard input and makes it available in +the predefined @code{REPLY} environment variable, or any other +variable whose name is passed as an argument. This allows processing +data structured in lines in a quite natural way. For example, the +following program prints the third field of each line, with fields +separated by commas, until standard input is exhausted: + +@example +# Process one line at a time. +while read +do + echo "The third field is " `echo $REPLY | cut -d, -f 2` +done +@end example + +However, @command{read} is not very useful when it comes to +processing recutils records in the shell. Even though it is +possible to customize the character used by @command{read} to split +the input into records, we would need to ignore the empty records in +the likely case of more than one empty line separating records. +Also, we would need to use @command{recsel} to access to the record +fields. Too complicated! + +Thus, the @command{readrec} bash built-in is similar to @command{read} with +the difference that it reads records instead of lines. It also +``exports'' the contents of the record to the user as the values of +several environment variables: + +@itemize @minus +@item @code{REPLY_REC} is set to the record read from standard input. +@item A set of variables @code{FIELD} named after each field found in +the record are set to the (decoded) value of the fields found in the +input record. When several fields with the same name are found in the +input record then a bash array is created. +@end itemize + +Consider for example the following simple database containing +contacts information: + +@example +Name: Mr. Foo +Email: foo@@bar.com +Email: bar@@baz.net +Checked: no + +Name: Mr. Bar +Email: bar@@foo.com +Telephone: 999666000 +Checked: yes +@end example + +@noindent +We would like to write some shell code to send an email to all the +contacts, but only if the contact has not been checked before, +@ie{} the @code{Checked} field contains @code{no}. The following code +snippet would do the job nicely using @command{readrec}: + +@example +recsel contacts.rec | while readrec +do + if [ $Checked = "no" ] + then + mail -s "You are being checked." $@{Email[0]@} < email.txt + recset -e "Email = '$Email'" -f Checked -S yes contacts.rec + sleep 1 + fi +done +@end example + +@noindent +Note the usage of the bash array when accessing the primary email +address of each contact. Note also that we update each contact to +figure as ``checked'', using @command{recset}, so she won't get +pestered again the next time the +script is run. + +@node Invoking the Utilities +@chapter Invoking the Utilities + +Certain options are available in all of these programs.

To port to older + small platforms where allocations larger than PTRDIFF_MAX could + in theory be a problem, you can use Gnulib's ialloc module, or + functions like ximalloc in Gnulib's xalloc module. + + Why not use 'ptrdiff_t' directly? + + * Maintainability: When reading and modifying code, it helps to know that + a certain variable cannot have negative values.

The idea + is that you would use these pre-tested macros to solve a + very specific set of problems, and they would run fast. + Caution: no side-effects in arguments please!! They may be + evaluated MANY times!! + + These macros operate a stack of objects. Each object starts life + small, and may grow to maturity. (Consider building a word syllable + by syllable.) An object can move while it is growing. Once it has + been "finished" it never changes address again. So the "top of the + stack" is typically an immature growing object, while the rest of the + stack is of mature, fixed size and fixed address objects. + + These routines grab large chunks of memory, using a function you + supply, called 'obstack_chunk_alloc'. On occasion, they free chunks, + by calling 'obstack_chunk_free'. You must define them and declare + them before using any obstack macros. + + Each independent stack is represented by a 'struct obstack'. + Each of the obstack macros expects a pointer to such a structure + as the first argument. + + One motivation for this package is the problem of growing char strings + in symbol tables. Unless you are "fascist pig with a read-only mind" + --Gosper's immortal quote from HAKMEM item 154, out of context--you + would not like to put any arbitrary upper limit on the length of your + symbols. + + In practice this often means you will build many short symbols and a + few long symbols. At the time you are reading a symbol you don't know + how long it is. One traditional method is to read a symbol into a + buffer, realloc()ating the buffer every time you try to read a symbol + that is longer than the buffer. This is beaut, but you still will + want to copy the symbol from the buffer to a more permanent + symbol-table entry say about half the time. + + With obstacks, you can work differently. Use one obstack for all symbol + names. As you read a symbol, grow the name in the obstack gradually. + When the name is complete, finalize it. Then, if the symbol exists already, + free the newly read name. + + The way we do this is to take a large chunk, allocating memory from + low addresses. When you want to build a symbol in the chunk you just + add chars above the current "high water mark" in the chunk. When you + have finished adding chars, because you got to the end of the symbol, + you know how long the chars are, and you can create a new object. + Mostly the chars will not burst over the highest address of the chunk, + because you would typically expect a chunk to be (say) 100 times as + long as an average object. + + In case that isn't clear, when we have enough chars to make up + the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed) + so we just point to it where it lies. No moving of chars is + needed and this is the second win: potentially long strings need + never be explicitly shuffled. Once an object is formed, it does not + change its address during its lifetime. + + When the chars burst over a chunk boundary, we allocate a larger + chunk, and then copy the partly formed object from the end of the old + chunk to the beginning of the new larger chunk. We then carry on + accreting characters to the end of the object as we normally would. + + A special macro is provided to add a single char at a time to a + growing object. This allows the use of register variables, which + break the ordinary 'growth' macro. + + Summary: + We allocate large chunks. + We carve out one object at a time from the current chunk. + Once carved, an object never moves. + We are free to append data of any size to the currently + growing object. + Exactly one object is growing in an obstack at any one time. + You can run one obstack per control block. + You may have as many control blocks as you dare. + Because of the way we do it, you can "unwind" an obstack + back to a previous state.

In addition to the standard + rand()/srand() like interface, this package also has a special state info + interface. The initstate() routine is called with a seed, an array of + bytes, and a count of how many bytes are being passed in; this array is + then initialized to contain information for random number generation with + that much state information. Good sizes for the amount of state + information are 32, 64, 128, and 256 bytes. The state can be switched by + calling the setstate() function with the same array as was initialized + with initstate(). By default, the package runs with 128 bytes of state + information and generates far better random numbers than a linear + congruential generator. If the amount of state information is less than + 32 bytes, a simple linear congruential R.N.G. is used. Internally, the + state information is treated as an array of longs; the zeroth element of + the array is the type of R.N.G. being used (small integer); the remainder + of the array is the state information for the R.N.G. Thus, 32 bytes of + state information will give 7 longs worth of state information, which will + allow a degree seven polynomial. (Note: The zeroth word of state + information also has some other information stored in it; see setstate + for details). The random number generation technique is a linear feedback + shift register approach, employing trinomials (since there are fewer terms + to sum up that way). In this approach, the least significant bit of all + the numbers in the state table will act as a linear feedback shift register, + and will have period 2^deg - 1 (where deg is the degree of the polynomial + being used, assuming that the polynomial is irreducible and primitive). + The higher order bits will have longer periods, since their values are + also influenced by pseudo-random carries out of the lower bits. The + total period of the generator is approximately deg*(2**deg - 1); thus + doubling the amount of state information has a vast influence on the + period of the generator. Note: The deg*(2**deg - 1) is an approximation + only good for large deg, when the period of the shift register is the + dominant factor. With deg equal to seven, the period is actually much + longer than the 7*(2**7 - 1) predicted by this formula. */ + + + +/* For each of the currently supported random number generators, we have a + break value on the amount of state information (you need at least this many + bytes of state info to support this random number generator), a degree for + the polynomial (actually a trinomial) that the R.N.G. is based on, and + separation between the two lower order coefficients of the trinomial. */ + +/* Linear congruential. */ +#define TYPE_0 0 +#define BREAK_0 8 +#define DEG_0 0 +#define SEP_0 0 + +/* x**7 + x**3 + 1. */ +#define TYPE_1 1 +#define BREAK_1 32 +#define DEG_1 7 +#define SEP_1 3 + +/* x**15 + x + 1. */ +#define TYPE_2 2 +#define BREAK_2 64 +#define DEG_2 15 +#define SEP_2 1 + +/* x**31 + x**3 + 1. */ +#define TYPE_3 3 +#define BREAK_3 128 +#define DEG_3 31 +#define SEP_3 3 + +/* x**63 + x + 1. */ +#define TYPE_4 4 +#define BREAK_4 256 +#define DEG_4 63 +#define SEP_4 1 + + +/* Array versions of the above information to make code run faster. + Relies on fact that TYPE_i == i. */ + +#define MAX_TYPES 5 /* Max number of types above. */ + +struct random_poly_info +{ + int seps[MAX_TYPES]; + int degrees[MAX_TYPES]; +}; + +static const struct random_poly_info random_poly_info = +{ + { SEP_0, SEP_1, SEP_2, SEP_3, SEP_4 }, + { DEG_0, DEG_1, DEG_2, DEG_3, DEG_4 } +}; + +static int32_t +get_int32 (void *p) +{ + int32_t v; + memcpy (&v, p, sizeof v); + return v; +} + +static void +set_int32 (void *p, int32_t v) +{ + memcpy (p, &v, sizeof v); +} + + +/* Initialize the random number generator based on the given seed.

Then the result has a zero at positions 0, ..., + j-1 and a 0x80 at position j.

A workaround is to + attach the current line number to the entity name: + + #define _GL_CONCAT0(x, y) x##y + #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y) + extern struct {...} * _GL_CONCAT (dummy, __LINE__); + + But this has the problem that two invocations of verify from + within the same macro would collide, since the __LINE__ value + would be the same for both invocations. (The GCC __COUNTER__ + macro solves this problem, but is not portable.) + + A solution is to use the sizeof operator. It yields a number, + getting rid of the identity of the type. Declarations like + + extern int dummy [sizeof (struct {...})]; + extern void dummy (int [sizeof (struct {...})]); + extern int (*dummy (void)) [sizeof (struct {...})]; + + can be repeated. + + * Should the implementation use a named struct or an unnamed struct? + Which of the following alternatives can be used? + + extern int dummy [sizeof (struct {...})]; + extern int dummy [sizeof (struct _gl_verify_type {...})]; + extern void dummy (int [sizeof (struct {...})]); + extern void dummy (int [sizeof (struct _gl_verify_type {...})]); + extern int (*dummy (void)) [sizeof (struct {...})]; + extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})]; + + In the second and sixth case, the struct type is exported to the + outer scope; two such declarations therefore collide. GCC warns + about the first, third, and fourth cases. So the only remaining + possibility is the fifth case: + + extern int (*dummy (void)) [sizeof (struct {...})]; + + * GCC warns about duplicate declarations of the dummy function if + -Wredundant-decls is used. GCC 4.3 and later have a builtin + __COUNTER__ macro that can let us generate unique identifiers for + each dummy function, to suppress this warning. + + * This implementation exploits the fact that older versions of GCC, + which do not support _Static_assert, also do not warn about the + last declaration mentioned above. + + * GCC warns if -Wnested-externs is enabled and 'verify' is used + within a function body; but inside a function, you can always + arrange to use verify_expr instead. + + * In C++, any struct definition inside sizeof is invalid. + Use a template type to work around the problem. */ + +/* Concatenate two preprocessor tokens. */ +#define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y) +#define _GL_CONCAT0(x, y) x##y + +/* _GL_COUNTER is an integer, preferably one that changes each time we + use it.

If the compiler does not support this + feature, the macro expands to an unused extern declaration. + + _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the + attribute used in _GL_WARN_ON_USE. If the compiler does not support + this feature, it expands to empty. + + These macros are useful for marking a function as a potential + portability trap, with the intent that "literal string" include + instructions on the replacement function that should be used + instead. + _GL_WARN_ON_USE is for functions with 'extern' linkage. + _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline' + linkage. + + However, one of the reasons that a function is a portability trap is + if it has the wrong signature. Declaring FUNCTION with a different + signature in C is a compilation error, so this macro must use the + same type as any existing declaration so that programs that avoid + the problematic FUNCTION do not fail to compile merely because they + included a header that poisoned the function.

Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in +dnl config.h. +dnl +dnl This canonical name can be used to select a particular assembly language +dnl source file that will interoperate with C code on the given host. +dnl +dnl For example: +dnl * 'i386' and 'sparc' are different canonical names, because code for i386 +dnl will not run on SPARC CPUs and vice versa. They have different +dnl instruction sets. +dnl * 'sparc' and 'sparc64' are different canonical names, because code for +dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code +dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit +dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit +dnl mode, but not both. +dnl * 'mips' and 'mipsn32' are different canonical names, because they use +dnl different argument passing and return conventions for C functions, and +dnl although the instruction set of 'mips' is a large subset of the +dnl instruction set of 'mipsn32'. +dnl * 'mipsn32' and 'mips64' are different canonical names, because they use +dnl different sizes for the C types like 'int' and 'void *', and although +dnl the instruction sets of 'mipsn32' and 'mips64' are the same. +dnl * The same canonical name is used for different endiannesses. You can +dnl determine the endianness through preprocessor symbols: +dnl - 'arm': test __ARMEL__. +dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL. +dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN. +dnl * The same name 'i386' is used for CPUs of type i386, i486, i586 +dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because +dnl - Instructions that do not exist on all of these CPUs (cmpxchg, +dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your +dnl assembly language source files use such instructions, you will +dnl need to make the distinction. +dnl - Speed of execution of the common instruction set is reasonable across +dnl the entire family of CPUs. If you have assembly language source files +dnl that are optimized for particular CPU types (like GNU gmp has), you +dnl will need to make the distinction. +dnl See <https://en.wikipedia.org/wiki/X86_instruction_listings>. +AC_DEFUN([gl_HOST_CPU_C_ABI], +[ + AC_REQUIRE([AC_CANONICAL_HOST]) + AC_REQUIRE([gl_C_ASM]) + AC_CACHE_CHECK([host CPU and C ABI], [gl_cv_host_cpu_c_abi], + [case "$host_cpu" in + +changequote(,)dnl + i[34567]86 ) +changequote([,])dnl + gl_cv_host_cpu_c_abi=i386 + ;; + + x86_64 ) + # On x86_64 systems, the C compiler may be generating code in one of + # these ABIs: + # - 64-bit instruction set, 64-bit pointers, 64-bit 'long': x86_64. + # - 64-bit instruction set, 64-bit pointers, 32-bit 'long': x86_64 + # with native Windows (mingw, MSVC). + # - 64-bit instruction set, 32-bit pointers, 32-bit 'long': x86_64-x32. + # - 32-bit instruction set, 32-bit pointers, 32-bit 'long': i386. + AC_COMPILE_IFELSE( + [AC_LANG_SOURCE( + [[#if (defined __x86_64__ || defined __amd64__ \ + || defined _M_X64 || defined _M_AMD64) + int ok; + #else + error fail + #endif + ]])], + [AC_COMPILE_IFELSE( + [AC_LANG_SOURCE( + [[#if defined __ILP32__ || defined _ILP32 + int ok; + #else + error fail + #endif + ]])], + [gl_cv_host_cpu_c_abi=x86_64-x32], + [gl_cv_host_cpu_c_abi=x86_64])], + [gl_cv_host_cpu_c_abi=i386]) + ;; + +changequote(,)dnl + alphaev[4-8] | alphaev56 | alphapca5[67] | alphaev6[78] ) +changequote([,])dnl + gl_cv_host_cpu_c_abi=alpha + ;; + + arm* | aarch64 ) + # Assume arm with EABI. + # On arm64 systems, the C compiler may be generating code in one of + # these ABIs: + # - aarch64 instruction set, 64-bit pointers, 64-bit 'long': arm64. + # - aarch64 instruction set, 32-bit pointers, 32-bit 'long': arm64-ilp32. + # - 32-bit instruction set, 32-bit pointers, 32-bit 'long': arm or armhf. + AC_COMPILE_IFELSE( + [AC_LANG_SOURCE( + [[#ifdef __aarch64__ + int ok; + #else + error fail + #endif + ]])], + [AC_COMPILE_IFELSE( + [AC_LANG_SOURCE( + [[#if defined __ILP32__ || defined _ILP32 + int ok; + #else + error fail + #endif + ]])], + [gl_cv_host_cpu_c_abi=arm64-ilp32], + [gl_cv_host_cpu_c_abi=arm64])], + [# Don't distinguish little-endian and big-endian arm, since they + # don't require different machine code for simple operations and + # since the user can distinguish them through the preprocessor + # defines __ARMEL__ vs. __ARMEB__. + # But distinguish arm which passes floating-point arguments and + # return values in integer registers (r0, r1, ...) - this is + # gcc -mfloat-abi=soft or gcc -mfloat-abi=softfp - from arm which + # passes them in float registers (s0, s1, ...) and double registers + # (d0, d1, ...) - this is gcc -mfloat-abi=hard.
