Contributing

Contributions are very welcome. The following will provide some helpful guidelines.

How to contribute

If you want to tackle an existing issue please add a comment to make sure the issue is sufficiently discussed and that no two contributors collide by working on the same issue. To submit a contribution, please follow the following workflow:

  • Fork the project
  • Create a feature branch
  • Add your contribution
  • Create a Pull Request

Commits

Commit messages should be clear and fully elaborate the context and the reason of a change. Each commit message should follow the following conventions:

  • it may use markdown to improve readability on GitHub
  • it should start with a title
    • less than 70 characters
    • starting lowercase
  • if the commit is not trivial the title should be followed by a body
    • separated from the title by a blank line
    • explaining all necessary context and reasons for the change
  • if your commit refers to an issue, please post-fix it with the issue number, e.g. #123 or Resolves #123

A full example:

Fix calculation of menu state

Due to operator precedence, `$(( $menu_state ± 1 % 3 ))`
was basically equivalent to `$(( $menu_state ± 1 ))`.

Also change 1-based `menu_state` to 0-based `selected_option_index`
to be able to directly use modulo arithmetics.

Resolves #7

Furthermore, commits must be signed off according to the DCO.
