Validations Go Report Card GitHub release GitHub go.mod Go version Slack Invite

A fast changelog generator that sources changes from GitHub PRs and issues, organized by labels.

Create a changelog from the last GitHib release until the current git HEAD tag/commit for the git repo in the current directory:

chronicle 

Create a changelog with all changes from v0.16.0 until current git HEAD tag/commit for the git repo in the current directory:

chronicle --since-tag v0.16.0

Create a changelog between two specific tags for a repo at the given path

chronicle --since-tag v0.16.0 --until-tag v0.18.0 ./path/to/git/repo

Create a changelog and guess the release version from the set of changes in the changelog

chronicle -n

Just guess the next release version based on the set of changes (don't create a changelog)

chronicle next-version

Default GitHub change definitions

The github.changes configurable is a list of mappings, each that take the following fields:

  • name: [string] singular, lowercase, hyphen-separated (no spaces) name that best represents the change (e.g. "breaking-change", "security", "added-feature", "enhancement", "new-feature", etc).
  • title: [string] title of the section in the changelog listing all entries.
  • semver-field: [string] change entries will bump the respective semver field when guessing the next release version. Allowable values: major, minor, or patch.
  • labels: [list of strings] all issue or PR labels that should match this change section.

The default value for github.changes is:

- name: security-fixes
