GithubFastChangelog

Uses GitHub's v4 GraphQL API to generate a CHANGELOG from PRs matching a list of commits.

I used to use GitHub Changelog Generator (which is a better and way more complete project), but the project I worked on was too large (several thousand PRs) and always hit github's rate limit.

This project uses GitHub's v4 GraphQL API to query the PRs very efficiently and shouldn't ever hit the rate limit

$ gem install github_fast_changelog

This expects a list of commits (some of which should match the merge commit of a PR) on STDIN. Writes markdown to STDOUT.

$ export GITHUB_ACCESS_TOKEN=....
$ git rev-list v2.4...v2.5 | github_fast_changelog example/github_repo > CHANGELOG.md

Output is:

- Add usage instructions to README [#1](https://github.com/jhawthorn/github_fast_changelog/pull/1) ([jhawthorn](https://github.com/jhawthorn))

Rendered:

• Add usage instructions to README #1 (jhawthorn)
