🎀 Changelog

This is the changelog for the Hilbish shell made in Go and Lua.

0.7.1 - 2021-11-22

Fixed

  • Tab complete absolute paths to binaries properly
  • Allow execution of absolute paths to binaries (06272778f8 regression)

0.7.0 - 2021-11-22

Added

  • hilbish.interactive and hilbish.login properties to figure out if Hilbish is interactive or a login shell, respectively.
  • hilbish.read function to take input more elegantly than Lua's io.read
  • Tab Completion Enhancements
    • A new tab complete API has been added. It is the single complete function which takes a "scope" (example: command.<cmdname>) and a callback which is expected to return a table. Users can now add custom completions for specific commands. An example is:
    complete('command.git', function()
      return {
      	'add',
      	'version',
      	commit = {
      		'--message',
      		'--verbose',
      		'<file>'
      	}
      }
    end)
    
    For git, Hilbish will complete commands add, version and commit. For the commit subcommand, it will complete the flags and/or files which <file> is used to represent.
    • Hilbish will now complete binaries in $PATH, or any executable to a path (like ./ or ../)
    • Files with spaces will be automatically put in quotes and completions will work for them now.
  • prependPath function (#81)
  • Signal hooks (#80)
    • This allows scripts to add their own way of handling terminal resizes (if you'd need that) or Ctrl-C
  • Module properties (like hilbish.ver) are documented with the doc command.
  • Document bait hooks

Fixed

  • The prompt won't come up on terminal resize anymore.
  • appendPath should work properly on Windows.
  • A panic when a commander has an error has been fixed.

0.6.1 - 2021-10-21

Fixed

  • Require paths now use the dataDir variable so there is no need to change it anymore unless you want to add more paths
  • Remove double slash in XDG data require paths
  • Ctrl+C is handled properly when not interactive and won't result in a panic anymore
  • Commanders are handled by the sh interpreter library only now, so they work with sh syntax

Changed

  • Error messages from fs functions now include the path provided

0.6.0 - 2021-10-17

Added

  • Hilbish will expand ~ in the preloadPath and samplePathConf variables. These are for compile time.
  • On Windows, the hostname in %u has been removed.
  • Made it easier to compile on Windows by adding Windows-tailored vars and paths.
  • Add require paths ./libs/?/?.lua
  • Hilbish will now respect $XDG_CONFIG_HOME and will load its config and history there first and use Lua libraries in there and $XDG_DATA_HOME if they are set. (#71)
    • If not, Hilbish will still default to ~
  • Added some new hooks
    • command.precmd is thrown right before Hilbish prompts for input
    • command.preexec is thrown right before Hilbish executes a command. It passes 2 arguments: the command as the user typed, and what Hilbish will actually execute (resolved alias)
  • hilbish.dataDir is now available to know the directory of Hilbish data files (default config, docs, preload, etc)
  • A docgen program has been added to cmd/docgen in the GitHub repository, As the name suggests, it will output docs in a docs folder for functions implemented in Go
  • All hilbish modules/libraries now have a __doc metatable entry which is simply a short description of the module.
  • fs.readdir(dir) has been added. It will return a table of files in dir
  • Errors in the fs.mkdir function are now handled.
  • Breaking Change: fs.cd no longer returns a numeric code to indicate error. Instead, it returns an error message.
  • The doc command has been added to document functions of Hilbish libraries. Run the command for more details.
  • link(url, text) has been added to ansikit. It returns a string which can be printed to produce a hyperlink in a terminal. Note that not all terminals support this feature.
  • The Succulent library has been added. This includes more utility functions and expansions to the Lua standard library itself.
  • The command string is now passed to the command.exit hook

Changed

  • Hilbish won't print an extra newline at exit with ctrl + d
  • command.exit with 0 exit code will now be thrown if input is nothing
  • Breaking Change: fs.stat has been made better. It returns a proper table instead of userdata, and has fields instead of functions
    • It includes name, mode as a octal representation in a string, isDir, and size

Fixed

  • timeout() is now blocking
  • Directories with spaces in them can now be cd'd to
  • An alias with the same name as the command will now not cause a freeze (#73)
  • Userdata is no longer returned in the following cases:
    • Commander arguments
    • fs functions

0.5.1 - 2021-06-16

Added

  • Add ~/.config/hilbish as a require path

Changed

  • cd hook is only thrown after directory has actually changed

Fixed

  • Handle error in commander properly, preventing a panic from Lua

0.5.0 - 2021-06-12

An absolutely massive release. Probably the biggest yet, includes a bunch of fixes and new features and convenient additions to the Lua API.

Added

  • -n flag, which checks Lua for syntax errors without running it
  • exec(command) function, acts like the exec builtin in sh
    • Example: exec 'awesome' in an .xinitrc file with Hilbish as shebang
  • Commands from commander can now return an exit code
commander.register('false', function()
return 1
end)

When false is run, it will have the exit code of 1, this is shorter/easier than throwing the command.exit hook and can work if the functionality of that changes

  • Added -c description
  • args variable, set when Hilbish runs a Lua script. It is an array that includes the execute path as the first argument
  • Lua code can be aliased
  • Recursive aliases
    • At the moment this only works for the first argument
  • Hilbish can now be used with Hilbiline if compiled to do so (currently only for testing purposes)
  • goro(func) runs a function in a goroutine. With channels that gopher-lua also provides, one can do parallelism and concurrency in Lua (but go style).
    • coroutine no those dont exist they dont matter goro is easier
  • cd - will change to the previous directory
  • hilbish.cwd() gets the current working directory
  • timeout(func, time) works exactly like the setTimeout function in JavaScript. It will run func after a period of time in milliseconds.
  • interval(func, time) works exactly like the setInterval function in JavaScripit. It will run func every time milliseconds
  • hilbish.home is a crossplatform Lua alternative to get the home directory easily.
  • commander.deregister(cmdName) de-registers any command defined with commander.

Changed

  • Breaking Change: Move _user and _ver to a global hilbish table
    • Accessing username and Hilbish version is now done with hilbish.user and hilbish.ver
  • hilbish.run(cmd) runs cmd with Hilbish's sh interpreter. Using this function instead of os.execute ensures that sh syntax works everywhere Hilbish does.
  • hilbish.flag(flag) checks if flag has been passed to Hilbish.
  • Aliases now work with every command and not only the first one
    • Therefore alias1; alias2 works now
  • command.not-found hook
  • $SHLVL is now incremented in Hilbish. If not a valid number, it will be changed to 1
  • fs.mkdir can now make directories recursively if the 2nd argument is set to true
    • fs.mkdir('path/to/dir', true)
  • Hilbish runs a preload.lua file in the current directory first, then falls back to the global preload. Before the order was reversed.
  • Check if aliased command is defined in Lua, so registered commanders can be aliased
  • Add input to history before alias expansion. Basically, this adds the actual alias to history instead of the aliased command.
  • Global preload path, require paths, default config directory and sample config directory can now be changed at compile time to help support other systems.

Fixed

  • cd now exits with code 1 instead of the error code if it occurs
  • Don't append directory to $PATH with appendPath if its already there
  • Continued input is no longer joined with a space unless explicitly wanted
  • Hilbish won't try to go interactive if it isn't launched in a TTY (terminal)
  • Ctrl+D on a continue prompt with no input no longer causes a panic
  • Actually handle the -h/--help option

0.4.0 - 2021-05-01

Added

  • Ctrl C in the prompt now cancels/clear input (I've needed this for so long also)
  • Made Hilbish act like a login shell on login
    • If Hilbish is the login shell, or the -l/--login flags are used, Hilbish will use an additional ~/.hprofile.lua file, you can use this to set environment variables once on login
  • -c has been added to run a single command (this works exactly like being in the prompt would, so Lua works as well)
  • -i (also --interactive) has been added to force Hilbish to be an interactive shell in cases where it usually wont be (like with -c)
  • Use readline in continue prompt
  • Added a mulitline hook that's thrown when in the continue/multiline prompt
  • Added appendPath function to append a directory to $PATH
    • ~ will be expanded to $HOME as well
  • A utility string.split function is now added
    • string.split(str, delimiter)
  • Added a _user variable to easily get current user's name

Changed

  • BREAKING Change: Lunacolors has replaced ansikit for formatting colors, which means the format function has been removed from ansikit and moved to Lunacolors.
    • Users must replace ansikit with lunacolors in their config files
  • A getopt-like library is now used for command line flag parsing
  • cd builtin now supports using environment variables
    • This means you can now cd $NVM_DIR as an example
  • Function arguments are now more strictly typed (prompt(nil) wouldnt work now)
  • Other general code/style changes

Fixed

  • Fix makefile adding Hilbish to /etc/shells on every make install

Since Lunacolors is a submodule, you may just want to completely reclone Hilbish recursively and then update (rerun make install) Or instead of recloning, run git submodule update --init --recursive in Hilbish's git directory

0.3.2 - 2021-04-10

Added

  • Add more functions to ansikit module
  • Add functions stat and mkdir to fs module
  • -C flag to define path to config
  • Add require path ~/.local/share/hilbish/libs

Changed

  • Continue to new line if output doesnt end with it

Observed:

Observed

0.3.1 - 2021-04-06

Fixed

  • Fix %u in prompt format being full name and instead make it actually username

0.3.0 - 2021-04-05

Added

  • Added a multiprompt function to change the prompt of the multiline/continuation/newline prompt
  • _ver variable to get Hilbish's version from Lua

Changed

  • BREAKING Change: Removed Bait hooks command.success and command.fail, there is now the single hook command.exit, with a single argument passed which the exit code of the command. Use this to determine if a command has failed or not (failure is code != 0)
  • BREAKING Change: The Ansikit function text has been renamed to format.
  • fs.cd now throws an exception instead of silently failing, which you should handle with pcall
  • Enhancements to the cd command:
    • With no arguments will move to $HOME
    • Now throws a cd hook, with a single hook arg being the arguments to the command
    • Now works for directories with spaces
  • Lua input now throws a success hook if it succeeded
  • Command history is now saved to ~/.hilbish-history
  • Globals defined in Lua that are strings will be defined as an env variable (#16)
  • Input ending with \ will now go to a newline
  • exit command is now written in Lua

Fixed

  • Input is now trimmed
  • Internals are slightly cleaned up and codebase split up
  • Hilbish will now fall back to a builtin minimal config if the user's config has syntax errors on loading
  • Commands defined in Lua now report the error to the user cleanly instead of panicking if it has occured

0.2.0 - 2021-03-31

Added

  • Hooks (events) are the new and main thing in v0.2, you can now listen for hooks or cast out (emit) custom ones, via the bait package
  • ^^ to refer to the previous command. It's for the lazy hands like me, so I can do something like ENV=VAR ^^
  • Way more (more like any) comments in the core code.

Changed

  • Prompt has been changed to have printf-like verbs to format. This makes it easier on the user's side to configure, and doesn't require hooks to change it for things like current directory.
  • Default prompt's changed and the triangle changes color based on if command failed or not.

0.1.2 - 2021-03-24

Added

  • Add Lua input to history

0.1.1 - 2021-03-24

Added

  • Go to new line if sh input is incomplete
> for i in {1..5}

This input for example will prompt for more input to complete:

input

Added

  • Tab complete files
  • Makefile installation
  • sh support
