All codebases follow a style guide according to best practices in their respective languages. We enforces the following style guides by language:
Table of Contents
This project uses the conventional commit for your commit messages. This format is used to generate changelogs and ensures consistency and better filtering.
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.
The footer can contain a closing reference to an issue.
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:
Type | Description |
---|---|
build |
Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm). |
chore |
Used when changes are about organization, not about logic. |
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. |
revert |
Reverts a previous commit. |
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. |
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
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.
Examples
fix(pencil): stop graphite breaking when too much pressure applied
feat(pencil): add 'graphiteWidth' option
Fix #42
perf(pencil): remove graphiteWidth option
BREAKING CHANGE: The graphiteWidth option has been removed.
The default graphite width of 10mm is always used for performance reasons.
