Check Last Commit Message in a Pull Request

This GitHub action returns { shouldRun: true } if last commit message in a pr contains skip ci or ci skip.

Usage

name: Last commit message in pr

on: pull_request

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: skip or not
        id: skipornot
        with:
          token: ${{ secrets.personalAccessToken }}
        uses: atlwendy/retrieve-commit-messages-from-pr@v3
      - name: get my action output
        run: echo ::set-env name=SHOULD_RUN::${{ steps.skipornot.outputs.shouldRun }}
      - name: build
        run: yarn run build
        if: env.SHOULD_RUN == 'true'

If the repo is a public accessible repo, you don't need to provide any input. However, if it's a private repo, you'd need to provide a personal access token as input. GITHUB_TOKEN is not the correct token. It returns an object with key shouldRun and value being a string of boolean.

If last commit messages in a pr contains skip ci or ci skip, it returns:

{ shouldRun: 'false' }

This return value can then be assigned to an environment variable and used as condition for following steps.
