The project's aims are:

• validate CHANGELOG.md. Check that it conforms to Keep A Changelog and Common Changelog styles.
• ensure git tags are documented in CHANGELOG.md
• block pushing tags without changelog. See git pre-push section

The supported changelog style is Keep A Changelog style with these additions:

• allow changelog notes

  # Changelog
  Changelog notes
  
  ## [Unreleased]
  

• allow release notes (Common Changelog addition)

  ## [1.0.0] - 2023-05-05
  Release notes
  
  ### Added
   - add feature ...
  

• allow custom footer to separate tech stuff from changelog content. Useful for legal notes, text used by other scripts, HTML comments, etc

pre-commit hook

As a pre-commit hook. Add this section to your .pre-commit-config.yaml

- repo: https://github.com/aanatoly/check-changelog
  rev: '0.4.0'
  hooks:
    - id: check-changelog

git pre-push hook

As a git pre-push hook, check-changelog can block git from pushing tags without changelog. To install it that way, run the following commmands

# backup existing hook
mv .git/hooks/pre-push  .git/hooks/pre-push.bak
# install new hook
check-changelog --install=yes

and let's test it

git tag -a -m "abc.7.7" "abc.7.7"
git tag -a -m "abc.7.8" "abc.7.8"
git push --tags --dry-run

# check-changelog :: INFO  :: file CHANGELOG.md: starting
# check-changelog :: INFO  :: task check tags documentation: starting
# check-changelog :: INFO  :: scan 2 tags from 'hook' source
# check-changelog :: ERROR :: tag 'abc.7.7' not found
# check-changelog :: ERROR :: tag 'abc.7.8' not found
# check-changelog :: ERROR :: task check tags documentation: fail
# check-changelog :: ERROR :: file CHANGELOG.md: fail

git tag -d "abc.7.7"
git tag -d "abc.7.8"

Alternatives

check-changelog is a minimalistic tool by design. It checks the Changelog structure and does nothing else.

If you are looking for more, check python-kacl. It is a feature-rich tool capable of linting, fixing errors, and automating Changelog maintenance.
