Bugs

Please look at Github Issues.

Style

If you intend to patch and contribute to awesome, please respect the following guidelines.

Imitate the existing code style. For concrete rules:

  • Use 4 spaces indentation, do not use tabulator characters;

  • Place braces alone on new lines, and do not place braces for single line statement where it is not needed, i.e. no:

    if(bla) { x = 1; }

  • Do not put a space after if, for, while or function call statements;

  • The preferred line length is 80 characters;

  • Use /* */ for comments;

  • Use the API: there's a list of a_*() functions you should use instead of the standard libc ones. There is also a common API for linked lists, tabulars, etc.;

  • Be clear in what you do;

  • Prefix your function name with the module they are enhancing, i.e. if you add a function to manipulate a tag prefix it with tag_;

  • Write documentation for any new functions, options, whatever.

A vim modeline is set in each file to respect this.

Documentation of Lua files

For documentation purposes LDoc---see here for its documentation---is used. Comments that shall be parsed by LDoc have the following format:

--- summary.
-- Description; this can extend over
-- several lines

-----------------
-- This will also do.

--[[--
 Summary. A description
 ...;
]]

You can use the full power of Markdown with the extensions of Discount for markup in the comments.

Every module and class should have a short description at its beginning which should include @author author, @copyright year author, @release @AWESOME_VERSION@ and @module module-name or @classmod class-name.

Parameters of functions should be documented using @tparam <type> <parmname> <description>, and return values via @treturn <type> <description>.

For a more comprehensive description of the available tags see the LDoc documentation.

In addition to the regular tags provided by LDoc there are also some aliases for typed parameters defined in docs/config.ld, e.g. @client for @tparam client.client, @tag for @tparam tag and @tab for @tparam table).

Patches

If you plan to submit patches, you should follow the following guidelines.

Commits

  • make commits of logical units;
  • do not modify piece of code not related to your commit;
  • do not try to fix style of code you are not writing, it's just adding noise for no gain;
  • check for unnecessary whitespace with git diff --check before committing;
  • do not check in commented out code or unneeded files;
  • provide a meaningful commit message;
  • the first line of the commit message should be a short; description and should skip the full stop;
  • if you want your work included, add a Signed-off-by: Your Name <you@example.com> line to the commit message (or just use the option -s when committing);
  • make sure that you have tests for the bug you are fixing;
  • if possible, add a unit test to the test suite under spec/.

Patches

Submitting patches via pull requests on the Github project is the preferred method.

Pull request

git-send-email

  • use git format-patch -M to create the patch;
  • do not PGP sign your patch;
  • be careful doing cut & paste into your mailer, not to corrupt whitespaces;
  • if you change, add or remove the user API, the associated documentation should be updated as well;
  • send the patch to the list (awesome-devel@naquadah.org) if (and only if) the patch is ready for inclusion. If you use git-send-email(1), please test it first by sending email to yourself.
