About

Commitizen is a tool designed for teams.

Its main purpose is to define a standard way of committing rules and communicating it (using the cli provided by commitizen).

The reasoning behind it is that it is easier to read, and enforces writing descriptive commits.

Besides that, having a convention on your commits makes it possible to parse them and use them for something else, like generating automatically the version or a changelog.

Commitizen features

• Command-line utility to create commits with your rules. Defaults: Conventional commits
• Display information about your commit rules (commands: schema, example, info)
• Bump version automatically using semantic versioning based on the commits. Read More
• Generate a changelog using Keep a changelog

Requirements

Python 3.6+

Git 1.8.5.2+

Integrating with Pre-commit

Commitizen can lint your commit message for you with cz check. You can integrate this in your pre-commit config with:

---
repos:
  - repo: https://github.com/commitizen-tools/commitizen
    rev: master
    hooks:
      - id: commitizen
        stages: [commit-msg]

After the configuration is added, you'll need to run

pre-commit install --hook-type commit-msg

FAQ

Why are revert and chore valid types in the check pattern of cz conventional_commits but not types we can select?

revert and chore are added to the "pattern" in cz check in order to prevent backward errors, but officially they are not part of conventional commits, we are using the latest types from Angular (they used to but were removed). However, you can create a customized cz with those extra types. (See Customization
