PRacticle - the pr-activated-changelog-emitter

Installation

Install globally to get a binary executable in your system.

npm install -g @neo4j/practicle

Commands

generate-changelog

Generate a markdown formatted changelog from pull requests in a Github repository. The pull requests need to have a changelog label applied to them.

If the option --prev-version is omitted PRacticle finds all PR:s in the semver minor version and generates a complete changelog for all versions in that range.

I.e. if --next-version=3.2.5 is used, the output will include all changes from 3.2.0 to the upoming 3.2.5 release. They are grouped by version.

Versions are generated from git tags that has the format x.y.z.

When --prev-version is included, the same thing happens but it starts from the version of --prev-version rather than .0.

By default, the text for the changelog entry is taken from the pull request title. If the pull request body includes changelog: on a separate line, it will override the default text.

If release-tag-filter is included, which should be a regex string, it will be used to filter out releases by their tags. Default value complies with semantic versioning that can optionally start with a v, like 1.0.1 or v1.0.1
