Automatically Validate Commit Message Convention before Commit

To automatically validate commit messages, a git hook can be used in the commit-msg stage. The hook can be created either manually or using the pre-commit framework.

Setup with the pre-commit framework

• Create .pre-commit-config.yaml file in the root directory of your repository with following content.

  repos:
  - repo: https://github.com/qoomon/git-conventional-commits
    rev: <revision e.g. v2.1.0>
    hooks:
      - id: conventional-commits

• Install the pre-commit framework pip install pre-commit
• Install the commit-msg hook pre-commit install -t commit-msg

Setup manually

• Setup Commit Message Hook to
  • Navigate to your repository directory cd <repository-path>
  • Create git hook directory mkdir .git-hooks
  • Set update hooksPath git config core.hooksPath .git-hooks
  • Create commit message hook script and make it executable
    • touch .git-hooks/commit-msg && chmod +x .git-hooks/commit-msg
    • Open .git-hooks/commit-msg with your favorite editor and paste following script

      #!/bin/sh
      
      # fix for windows systems
      PATH="/c/Program Files/nodejs:$HOME/AppData/Roaming/npm/:$PATH"
      
      git-conventional-commits commit-msg-hook "$1"

  • Add and commit .git-hooks/commit-msg to repository
  • ⚠️ Whenever you clone your repository with git hooks you need to enable git hooks once again
    • git config core.hooksPath .git-hooks

Release Workflow with git-conventional-commits

• Determine version by git-conventional-commits version
• Update version in project files
  • Commit version bump git commit -am'build(release): bump project version to <version>'
• Generate change log by git-conventional-commits changelog --release <version> --file 'CHANGELOG.md'
  • Commit change log git commit -am'docs(release): create <version> change log entry'
• Tag commit with version git tag -a -m'build(release): <version>' '<version-prefix><version>'
• Push all changes git push
• Build and upload artifacts
