This action tries to figure out the current PR.

If the event is a pull_request, it's very easy to get the current PR number from the context via ${{ github.event.number }}, but unfortunately this information does not seem to be readily available for a push event. This action sends a request to GitHub to find the PR associated with the current SHA, and returns its number in the number output. number will be an empty string if there is no PR.

Additionally, title and body outputs are available as well to get the respective title and body of the PR.

By default, gh-find-current-pr will only return open PRs. You can pass in a state parameter to pick "open", "closed", or "all" PRs.

steps:
  - uses: actions/checkout@v4
  # Find the PR associated with this push, if there is one.
  - uses: jwalton/gh-find-current-pr@master
    id: findPr
    with:
      # Can be "open", "closed", or "all".  Defaults to "open".
      state: open
  # This will echo "Your PR is 7", or be skipped if there is no current PR.
  - run: echo "Your PR is ${PR}"
    if: success() && steps.findPr.outputs.number
    env:
      PR: ${{ steps.findPr.outputs.pr }}
