Contributor Guidelines

Commit Message Convention

For all commit messages the Conventional Commits styleguide shall be followed. More information here

Editor Plugins

Enforcing commit message style via git hooks

Please copy the commit-msg git hook in .githooks into your local .git/hooks folder.
Before each commit the commit message gets checked and rejected if it does not meet the angular message style.

Summary (from the angular guidelines)

Motivation: More readable commit history and using the git commit messages to generate the automatic changelogs.

Commit Message Format

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

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

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

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

The footer should contain a closing reference to an issue if any.

Samples: (even more samples)

Types

Must be one of the following:

  • feat: A new feature
  • fix: A bug fix
  • refactor: A code change that neither fixes a bug nor adds a feature
  • chore: Other changes that don't modify src or test
  • docs: Documentation only changes
  • build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
  • ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
  • perf: A code change that improves performance
  • 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
  • revert: Reverts a previous commit

Subject

The subject contains a succinct description of the change:

  • use the imperative, present tense: "change" not "changed" nor "changes"
  • don't capitalize the 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.

Footer

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.

Code Style

Generally the Dart Codestyle shall be followed. This can most likely be automated via formatters in your IDE.
