pr-compliance-action

This action is meant to help in managing inbound PRs that may need adjustment other than code.

Functionality

It looks for the following:

  • PR Title formatted according to conventional commits.
  • PR Body refers to an issue, as detected by a regular expression
  • PR originates from a protected branch e.g. "main", (based on head ref)
  • PR includes modifications to specific files that should be reviewed carefully (e.g. package.json)

Sample Workflow File

Below is a sample yaml file to place in .github/workflows/:

name: PR Compliance

on:
  pull_request_target:
    types: [opened, edited, reopened]

# Action should have write permission to make updates to PR
permissions:
  pull-requests: write

jobs:
  pr-compliance:
    runs-on: ubuntu-latest
    steps:
      - uses: mtfoley/pr-compliance-action@main
        with:
          # all inputs are optional
          watch-files: |
            package.json
            npm-shrinkwrap.json

Behavior

This action drives the following outcomes with all inputs at default:

Check Outcome on Flagging
PR Title Lint Fails Action shows as failed check. Action leaves review comment.
PR Does Not Refer to Issue Action closes issue. Action leaves review comment.
PR Originates from Protected Branch Action closes issue. Action leaves review comment.
PR Modifies Watched Files Action leaves review comment.

If a PR is initially deemed non-compliant by the action and a review comment is left, the action will update this same review comment each time it runs again (e.g. if the PR title or description changes). If the PR is found to be compliant after changes, the review comment will be updated to reflect this.

Inputs

All inputs are optional and have default values.

ignore-team-members true Whether to ignore in the case that the PR author is a) the owner of repository, or b) has a public membership1 in the org that owns the repository.

watch-files-check Result of check for watched files having been modified. True if no modifications found to watched files.

Footnotes

  1. In a case where a contributor has a private membership to the org, the ignore-authors may be used to skip checks - however, this workflow file configuration could effectively make membership public. ↩

  2. Default regular expression is based on linking to an issue using a keyword. To keep PRs related to issues within the same same repo, we use the KEYWORD #ISSUE-NUMBER syntax. However, one could also use a regular expression like (fix\|resolv\|clos)(e)*(s|d)* (my-org)\/([a-z0-9\-_]*)#\d+ ↩
