README

Generate pretty release changelogs using the commit log and Github API. Changelog entries are in the following format:

{short hash} {summary} (#{PR number}) by {author}, {co-author 1}, {co-author n}...

Some notes about the format:

Currently, this format is hard-coded and can't be customized
Merge commits are excluded
PR number is only added if not already in the summary (and a PR exists for the commit)
Author/Co-Author's are converted to GitHub username links if possible to take advantage of GitHub Release Avatar List

See an example of a release generated using this package.

Installation

To avoid dependency conflicts with this tool, it is recommended to install as an executable PHAR or install in your project (or globally) using the composer bin plugin.

PHAR

wget https://github.com/zenstruck/changelog/releases/latest/download/changelog.phar -O changelog && chmod +x changelog
mv changelog ~/bin # assumes ~/bin is in your PATH

Composer Bin Plugin

Requires the bamarni/composer-bin-plugin.

# locally in your project
composer bin changelog require zenstruck/changelog

# globally
composer global bin changelog require zenstruck/changelog

Configuration

The changelog binary should be executable either globally or via vendor/bin/changelog. For the remainder of this documentation, it is assumed this is available as changelog.

This tool requires a GitHub Personal Access Token to access the GitHub API. You can configure this in two ways:

GITHUB_API_TOKEN environment variable (ie prefix changelog commands with GITHUB_API_TOKEN=your-token)
Configure the token globally: changelog configure and follow the instructions to generate/save your token

Usage

Note: Commands that detect the repository from your current directory use the upstream origin if available.

Changelog Preview

Generate a changelog preview in your console:

# "interactive", detects repository from current directory, from=last release on GitHub, to=default branch
changelog generate

# equivalent to above, "generate" is the "default command"
changelog

# outputs changelog for "your/repository" from tag "v1.0.0" to branch "main"
changelog generate --repository=your/repository --from=v1.0.0 --to=main

Run changelog generate --help to see full command documentation.

Create Changelog File

Create a CHANGELOG.md file for the current repository based on existing releases. This file is created in the current working directory. It is up to you to add/commit to the repository.

# create a CHANGELOG.md
bin/changelog file:create

# customize the filename
bin/changelog file:create --filename=changes.md

# exclude releases marked as "pre-release"
bin/changelog file:create --exclude-pre-releases

Create Release

Create (and optionally push) a release changelog (exclude --push to preview what the release will look like):

# "interactive" - detects repository from current directory, suggests next version
changelog release

# generates changelog from v1.0.0 to main and creates v1.1.0 release on GitHub that has the changelog as the body
changelog release v1.1.0 --repository=your/repository --from=v1.0.0 --target=main --push

# detects repository from current directory, from=last release on GitHub, target=default branch
changelog release v1.1.0 --push

You can use semantic versioning keywords as the next version. The following example assumes your last release was v1.0.0.

changelog release bug --push # creates v1.0.1 release
changelog release feature --push # creates v1.1.0 release
changelog release major --push # creates v2.0.0 release

Run changelog release --help to see full command documentation.

Release Status Dashboard

Generate a simple dashboard for a GitHub organization showing package release statuses.

changelog dashboard my-org

# will ask for organization and give option to save as default.
# if saved, subsequent calls to the command will not require the organization argument
