A PHP CLI to update a changelog with the latest release notes.

Want to automate the process of updating your changelog with GitHub Actions? Checkout thestefanzweifel/changelog-updater-action which does exactly that.

If your changelog follows the"Keep a Changelog" format and has a "Unreleased" heading in it, the CLI will update the link in and place the release notes below heading.

You can install the changelog-updater CLI as a composer dependency in your project or globally. It requires PHP 8.2 or higher.

composer global require wnx/changelog-updater

You can usechangelog-updater by running theupdate command with the following options.

php changelog-updater update \--release-notes="### Added-NewFeature A-NewFeature B### Changed- Update Feature C### Removes- Remove Feature D" \--latest-version="v1.0.0" \--release-date="2021-08-07" \--path-to-changelog="CHANGELOG.md" \--compare-url-target-revision="1.x" \--write

--release-date,--path-to-changelog,--compare-url-target-revision and--write are optional. Learn more about the options by runningphp changelog-updater update --help.

If a given version already exists in the CHANGELOG, the CLI will display a warning and not update the CHANGELOG.

The CLI does its best to place the given release notes in the right place.The CLI looks for the first second level heading in your currentCHANGELOG.md file. It assumes that this heading represents the previous version. Here is an example of aCHANGELOG.md that the CLI can understand.

# Changelog## v1.0.0 - 2021-11-01### Added- Initial Release

The CLI will then place the new version and its release notesabove the existing versions.

# Changelog+ ## v1.1.0 - 2021-11-10++ ### Added++ * New Feature+## v1.0.0 - 2021-11-01### Added* Initial Release

If the changelog does not contain a second level heading, it considers the changelog to be "empty". It will then place the release notes at the bottom of the document.

# ChangelogAll notable changes to this project will be documented in this file.+## v1.0.0 - 2021-11-01++### Added++* Initial Release

If your changelog follows the"Keep a Changelog" format and contains an "Unreleased"-heading with a link to the repository compare view, the CLI will automatically update the link in the Unreleased heading.

Here is an example of a changelog, before it is updated with the CLI.

# Changelog## [Unreleased](https://github.com/org/repo/compare/v1.0.0...HEAD)Please do not update the unreleased notes.<!-- Content should be placed here -->## v1.0.0 - 2021-01-01### Added- Initial Release

Below you find a diff-view of how the CLI will update the changelog.

# Changelog+## [Unreleased](https://github.com/org/repo/compare/v1.1.0...HEAD)-## [Unreleased](https://github.com/org/repo/compare/v1.0.0...HEAD)Please do not update the unreleased notes.<!-- Content should be placed here -->+## [v1.1.0](https://github.com/org/repo/compare/v1.0.0...v1.1.0) - 2021-02-01++### Added++* New Feature A+* New Feature B+## v1.0.0 - 2021-01-01### Added* Initial Release

The content between the "Unreleased"-heading and the latest version will remain untouched by the CLI.

If you don't have a "Unreleased"-heading in your changelog, but the headings of your previous releases contain a link to the repository compare view, the CLI will add links to the compare view to the added release heading.

# Changelog+## [v1.1.0](https://github.com/org/repo/compare/v1.0.0...v1.1.0) - 2021-02-01++### Added++* New Feature A+* New Feature B+## [v1.0.0](https://github.com/org/repo/compare/v0.1.0...v1.0.0) - 2021-01-01### Added* Initial Release
