Pull Request Labeler

Pull request labeler triages PRs based on the paths that are modified in the PR.

To use, create a .github/labeler.yml file with a list of labels and minimatch globs to match to apply the label.

Example:

label1:
- example1/**/*

label2: example2/*

label3:
- example3/*
- example3/**/*.yml

Where "label1" is the name of the label on your repository that you want to add (eg: "merge conflict", "needs-updating") and "example1/**/*" is the path of the changed files.

Then create a workflow (eg: .github/workflows/label.yml see Creating a Workflow file) utilizing the labeler action, granting access to the GITHUB_TOKEN so the action can make calls to GitHub's rest API:

name: "Pull Request Labeler"
on:
- pull_request

jobs:
  triage:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/labeler@v2
      with:
        repo-token: "${{ secrets.GITHUB_TOKEN }}"
