|
|
* UTF-8 in, UTF-8 out. No exceptions.
|
|
|
|
* SHA256 for auth_hash. Server will do a basic check to make sure of this.
|
|
|
|
* Security is not a #1 concern. Basic authorization will be implemented
|
|
to **help prevent** users from impersonating each other, but this isn't
|
|
intended to be bulletproof and you shouldn't trust the system with a
|
|
password you use elsewhere. All clients should inform the user of this.
|
|
|
|
* Command-line, on-tilde comes first. Local clients should be possible using
|
|
SSH port binding, however features like inline images, graphical elements
|
|
and the like will never be implemented as part of the protocol. Local clients
|
|
can definitely do things like URL image previews though. Hyperlinks with a
|
|
different text then the link itself will never be implemented.

Text Entities
|
|
-------------
|
|
|
|
The `entities` attribute is an array of objects that represent blocks
|
|
of text within a post that have special properties. Clients may safely
|
|
ignore these things without losing too much meaning, but in a rich
|
|
implementation like an Emacs or GUI, they can provide
|
|
some highlighting and navigation perks. The array object may be
|
|
empty. If its not, its populated with arrays representing the
|
|
modifications to be made.
|
|
|
|
Objects **always** have a minimum of 3 attributes:
|
|
```
|
|
["quote", 5, 7]
|
|
```
|
|
object[0] is a string representing the attribute type. They are
|
|
documented below. The next two items are the indices of the
|
|
property in the body string. The way clients are to access these
|
|
indices is beyond the scope of this document; accessing a subsequence
|
|
varies a lot between programming languages.
|
|
|
|
Some objects will provide further arguments beyond those 3. They will
|
|
always be at the end of the array.
|
|
|
|
| Name | Description |
|
|
|-------------+----------------------------------------------------------|
|
|
| `quote` | This is a string that refers to a previous post number. |
|
|
| | These are formatted like >>5, which means it is a |
|
|
| | reference to `post_id` 5. These are not processed in |
|
|
| | thread OPs. >>0 may be used to refer to the OP. In |
|
|
| | addition to the indices at i[1] and i[2], a fourth value |
|
|
| | is provided, which is an integer of the `post_id` being |
|
|
| | quoted. Note that the string indices include the >>'s. |
|
|
|-------------+----------------------------------------------------------|
|
|
| `linequote` | This is a line of text, denoted by a newline during |
|
|
| | composure, representing text that is assumed to be |
|
|
| | a quote of someone else. The indices span from the > |
|
|
| | until (not including) the newline. |
|
|
|-------------+----------------------------------------------------------|
|
|
| `color` | This is a block of text, denoted by [[color: body]] |
|
|
| | during composure. The body may span across newlines. |
|
|
| | A fourth item is provided in the array: it is one of the |
|
|
| | following strings representing the color. |
|
|
| | `red`, `green`, `yellow`, `blue`, `magenta`, or `cyan`. |
|
|
|-------------+----------------------------------------------------------|
|
|
| `bold` | Like color, except that no additional attribute is |
|
|
| `italic` | provided. it is denoted as [[directive: body]] during |
|
|
| `underline` | composure. |
|
|
|
|
|
|
Threads & Replies
|
|
-----------------
|
|
|
|
Threads are represented the same when using `thread_index` and
|
|
`thread_load`, except that the `replies` attribute is only
|
|
present with `thread_load`. The following attributes are
|
|
available on the parent object:
|
|
|
|
| Name | Description |
|
|
|---------------|------------------------------------------------------|
|
|
| `author` | The ID string of the author. |
|
|
|---------------|------------------------------------------------------|
|
|
| `thread_id` | The ID string of the thread. |
|
|
|---------------|------------------------------------------------------|
|
|
| `title` | The title string of the thread. |
|
|
|---------------|------------------------------------------------------|
|
|
| `body` | The body string of the post's text. |
|
|
|---------------|------------------------------------------------------|
|
|
| `entities` | A (possibly empty) array of entity objects for |
|
|
| | the post `body`. |
|
|
|---------------|------------------------------------------------------|
|
|
| `tags` | An array of strings representing tags the |
|
|
| | author gave to the thread at creation. |
|
|
| | When empty, it is an array with no elements. |
|
|
|---------------|------------------------------------------------------|
|
|
| `replies` | An array containing full reply objects in |
|
|
| | the order they were posted. Your clients |
|
|
| | do not need to sort these. Array can be empty. |
|
|
|---------------|------------------------------------------------------|
|
|
| `reply_count` | An integer representing the number of replies |
|
|
| | that have been posted in this thread. |
|
|
|---------------|------------------------------------------------------|
|
|
| `lastmod` | Unix timestamp of when the thread was last |
|
|
| | posted in, or a message was edited. |
|
|
|---------------|------------------------------------------------------|
|
|
| `edited` | Boolean of whether the post has been edited. |
|
|
|---------------|------------------------------------------------------|
|
|
| `created` | Unix timestamp of when the post was originally made. |
|
|
|
|
The following attributes are available on each reply object in `replies`:
|
|
|
|
|
|
| Name | Description |
|
|
|------------|---------------------------------------------------------|
|
|
| `post_id` | An integer of the posts ID; unlike thread and user ids, |
|
|
| | this is not a uuid but instead is incremental, starting |
|
|
| | from 1 as the first reply and going up by one for each |
|
|
| | post. These may be referenced by `quote` entities. |
|
|
|------------|---------------------------------------------------------|
|
|
| `author` | Author ID string |
|
|
|------------|---------------------------------------------------------|
|
|
| `body` | The body string the reply's text. |
|
|
|------------|---------------------------------------------------------|
|
|
| `entities` | A (possibly empty) array of entity objects for |
|
|
| | the reply `body`. |
|
|
|------------|---------------------------------------------------------|
|
|
| `lastmod` | Unix timestamp of when the post was last edited, or |
|
|
| | the same as `created` if it never was. |
|
|
|------------|---------------------------------------------------------|
|
|
| `edited` | A boolean of whether the post was edited. |
|
|
|------------|---------------------------------------------------------|

Errors
|
|
------
|
|
|
|
Errors are represented in the `error` field of the response. The error
|
|
field is always present, but is usually false. If its not false, it is
|
|
an object with the fields `code` and `description`. `code` is an integer
|
|
representing the type of failure, and `description` is a string describing
|
|
the problem. `description` is intended for human consumption; in your client
|
|
code, use the error codes to handle conditions. The `presentable` column
|
|
indicates whether the `description` should be shown to users verbatim.
|
|
|
|
| Code | Presentable | Documentation |
|
|
|------|--------------|---------------------------------------------------|
|
|
| 0 | Never, fix | Malformed json input. `description` is the error |
|
|
| | your client | string thrown by the server-side json decoder. |
|
|
|------|--------------|---------------------------------------------------|
|
|
| 1 | Not a good | Internal server error. Unaltered exception text |
|
|
| | idea, the | is returned as `description`. This shouldn't |
|
|
| | exceptions | happen, and if it does, make a bug report. |
|
|
| | are not | clients should not attempt to intelligently |
|
|
| | helpful | recover from any errors of this class. |
|
|

|
|
| 4 | Only during | Invalid or unprovided `user`. |
|
|
| | registration | |
|
|
| | | During registration, this code is returned with a |
|
|
| | | `description` that should be shown to the user. |
|
|
| | | It could indicate an invalid name input, an |
|
|
| | | occupied username, invalid/missing `auth_hash`, |
|
|
| | | etc. |
|
