Changelog generator

Groups commit subjects by type so release notes can be written in minutes.

When to use

  • The user is cutting a release and needs notes.
  • The user asks what changed since the last tag.
  • A pull request needs a summary of its commits.

How to run

Pipe git log with the %h|%s format into the script:

git log v1.0.0..HEAD --pretty=format:"%h|%s" | python scripts/make_changelog.py --title "v1.1.0"

Without a title, the heading is Changelog.

Output

Markdown on standard output. Sections appear in a fixed order: Breaking changes, Features, Fixes, Performance, Documentation, Refactoring, Tests, Build and CI, Other. Empty sections are left out. A ! after the type (feat!:) or a BREAKING CHANGE marker puts the commit under Breaking changes. Each line shows the scope in bold, the subject and the short hash.

After running

Read the draft once, merge duplicate lines, and rewrite subjects that only make sense to the author. Add a short summary paragraph on top for releases with user visible changes.

Errors

Empty input prints a heading and the line No commits found.. Lines without a | separator are ignored.

Reviews
