Create Comment

A GitHub Action that post comment on a GitHub Issue or Pull Request. If the same content is posted before, this action will delete the existing one and post a new one.

This action extract the number from an issue or a pull request which has triggered this by default. You don't need to specify the issue number by ${{ github.event.issue.number }} or ${{ github.event.pull_request.number }} if you want to post to its issue or pull request.

Usage

      - name: Create Comment
        uses: KeisukeYamashita/create-comment@v1
        with:
          number: 1
          comment: Comment for Issue or GitHub Pull Request

Post a comment and close the previous same comment

This is just an example to show one way in which this action can be used.

    runs-on: ubuntu-latest
    steps:
      - name: Post comment

        with:
          comment: |
            Issue title must start with 'ABC-'.
            Auto-closing this issue.
