Contribution

I welcome everyone to contribute to this repo. Let us build awesome software - together. In order to streamline contribution to this repo, some guidelines are described below.

Tests

In order to maintain a maximum of software quality, tests are needed. Whenever you contribute, please make sure that appropriate tests are in place. Also contributing tests only is highly valuable for the project.

Git Commit Guidelines

These rules are adopted from the AngularJS commit conventions.

Commit Message Format

Each commit message starts with a type, a scope, and a subject.

Below that, the commit message has a body.

  • type: what type of change this commit contains.
  • scope: what item of code this commit is changing.
  • subject: a short description of the changes.
  • body (optional): a more in-depth description of the changes
<type>(<scope>): <subject>
<BLANK LINE>
<body>

Examples:

feat(ruler): add inches as well as centimeters
fix(protractor): fix 90 degrees counting as 91 degrees
refactor(pencil): use graphite instead of lead

Closes #640.

Graphite is a much more available resource than lead, so we use it to lower the price.
fix(pen): use blue ink instead of red ink

BREAKING CHANGE: Pen now uses blue ink instead of red.

To migrate, change your code from the following:

`pen.draw('blue')`

To:

`pen.draw('red')`

Any line of the commit message should not be longer 100 characters. This allows the message to be easier to read on github as well as in various git tools.

Type

Is recommended to be one of the below items. Only feat and fix show up in the changelog, in addition to breaking changes (see breaking changes section at bottom).

  • feat: A new feature
  • fix: A bug fix
  • docs: Documentation only changes
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • refactor: A code change that neither fixes a bug or adds a feature
  • test: Adding missing tests
  • chore: Changes to the build process or auxiliary tools and libraries such as documentation generation

Scope

The scope could be anything specifying place of the commit change. Usually, the affected resource is named here.

Subject

The subject contains 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

Breaking Changes

Put any breaking changes with migration instructions in the commit body.

If there is a breaking change, put BREAKING CHANGE: in your commit body, and it will show up in the changelog.
