CodeMention is a GitHub Action that mentions users and teams who subscribe to certain file changes on pull requests. See in pull requests in the codemention-test repo for examples of how this looks like.

This is similar to Codenotify, but this retrieves the diff via GitHub's REST API instead of using actions/checkout to clone the repo.

To use this GitHub Action, add a .github/codemention.yml file to your repo that contains mentions/notifications rules. An example looks like:

rules: - patterns: ['config/**'] mentions: ['sysadmin'] - patterns: ['db/migrate/**'] mentions: ['cto', 'dba'] - patterns: ['.github/**', 'spec/*.rb'] mentions: ['ci']

Add a .github/workflows/codemention.yml file to your repo with the following:

name: codemention on: pull_request_target: types: [opened, synchronize, ready_for_review] jobs: codemention: runs-on: ubuntu-latest permissions: contents: read pull-requests: write steps: - uses: tobyhs/codemention@v1 with: githubToken: ${{ secrets.GITHUB_TOKEN }}
