Pull Request Comment Trigger

Look for a "trigger word" in a pull-request description or comment, so that later steps can know whether or not to run.

Example usage in a workflow

Your workflow needs to listen to the following events:

on:
  pull_request:
    types: [opened]
  issue_comment:
    types: [created]

And then you can use the action in your jobs like this:

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: khan/pull-request-comment-trigger@v1.1.0
        id: check
        with:
          trigger: '@deploy'
          reaction: rocket
        env:
          GITHUB_TOKEN: '${{ secrets.GITHUB_TOKEN }}'
      - run: 'echo Found it!'
        if: steps.check.outputs.triggered == 'true'

Reaction must be one of the reactions here: https://developer.github.com/v3/reactions/#reaction-types And if you specify a reaction, you have to provide the GITHUB_TOKEN env vbl.

Inputs
