If you discover issues, have ideas for improvements or new features, please report them to the issue tracker of the repository or submit a pull request. Please, try to follow these guidelines when you do so.

Issue reporting

  • Check that the issue has not already been reported.
  • Check that the issue has not already been fixed in the latest code (a.k.a. master).
  • Be clear, concise and precise in your description of the problem.
  • Open an issue with a descriptive title and a summary in grammatically correct, complete sentences.
  • Include any relevant code to the issue summary.
  • If you're reporting performance issues it'd be nice if you added some profiling data (Emacs has a built-in profiler).

Pull requests

  • Read how to properly contribute to open source projects on Github.
  • Use a topic branch to easily amend a pull request later, if necessary.
  • Write good commit messages.
  • Mention related tickets in the commit messages (e.g. [Fix #N] Add missing autoload cookies)
  • Update the changelog.
  • Use the same coding conventions as the rest of the project.
  • Verify your Emacs Lisp code with checkdoc (C-c ? d).
  • Open a pull request that relates to only one subject with a clear title and description in grammatically correct, complete sentences.
