Contributing

Found a Bug? Got a suggestion?

If you find a bug in the source code, or want to make a suggestion, you can help us by submitting an issue to our GitHub Repository. Even better, you could submit a Pull Request.

Considering making your first Pull Request? You can learn how from this free series How to Contribute to an Open Source Project on GitHub

Pull Requests

  1. Fork the project
  2. Implement feature/fix bug & add test cases
  3. Ensure test cases & static analysis run successfully
  4. Submit a pull request to master branch

Please include unit tests where necessary to cover any functionality that is introduced.

Coding Guidelines

  • All features or bug fixes must be tested by one or more unit tests/specs
  • All public API methods must be documented and potentially also described in the user guide.
  • All code should follow the style of the existing code.

Commit messages

Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, an optional scope and a subject:

<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

The header is mandatory and the scope part of the header is optional.

Any line of the commit message cannot be longer than 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.

Footer should contain a closing reference to an issue if any.

Revert

If the commit reverts a previous commit, it should begin with revert:, followed by the header of the reverted commit. In the body it should say: This reverts commit <hash>., where the hash is the SHA of the commit being reverted.

Type

Must be one of the following:

  • build: Changes that affect the build system or external dependencies (example scopes: gradle, fastlane, npm)
  • ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
  • docs: Documentation only changes
  • feat: A new feature
  • fix: A bug fix
  • perf: A code change that improves performance
  • refactor: A code change that neither fixes a bug nor adds a feature
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • test: Adding missing tests or correcting existing tests

Scope

The scope should be the name of the part of the module affected e.g. sender, manager etc.

Subject

The subject contains a succinct description of the change:

  • use the imperative, present tense: “change” not “changed” nor “changes”
  • don’t capitalize first letter
  • no dot (.) at the end

Body

Just as in the subject, use the imperative, present tense: “change” not “changed” nor “changes”. The body should include the motivation for the change and contrast this with previous behavior.

The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.

Breaking Changes should start with the word BREAKING CHANGE: with a space or two newlines. The rest of the commit message is then used for this.
