Git Commit Guidelines

Introduction

These guidelines are based on Angular's commit convention and should be followed as closely as possible, or your pull-request is subject to rejection.

TL;DR:

Messages must be matched by the following regex:

Examples

Appears under "Features" header, crypto subheader:

Appears under "Bug Fixes" header, crypto subheader, with a link to issue #28:

Appears under "Performance Improvements" header, and under "Breaking Changes" with the breaking change explanation:

The following commit and commit 7d1bbd2 do not appear in the changelog if they are under the same release. If not, the revert commit appears under the "Reverts" header.

Full Message Format

A commit message consists of a header, body and footer. The header has a type, scope and subject:

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

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

If the prefix is feat, fix or perf, it will appear in the changelog. However, if there is any BREAKING CHANGE, the commit will always appear in the changelog.

Other prefixes are up to your discretion. Suggested prefixes are docs, chore, style, refactor, and test for non-changelog related tasks.

Scope

The scope could be anything specifying the place of the commit change. For example core, profile, crypto, database etc...

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.

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.
