how to set GitHub action to comment on new PR? - github

Question

I want to integrate github-action-comment-pull-request from the official GitHub marketplace.
This will be my yaml:
on: [pull_request]
jobs:
build:
name: Comment a pull_request
runs-on: ubuntu-latest
steps:
- name: Checkout
uses: actions/checkout#v2
- name: Comment a pull_request
uses: mb2dev/github-action-comment-pull-request#1.0.0
with:
message: "Hello, Thank you for this PR!"
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
My problem is that I want the message to be shown for all new PRs except PRs raised by specific users: userA, userB.
Preferably also to exclude users for a specific GitHub team.
Is this possible?

If you want this workflow to run the job for everyone except for specific users, an option could be to add an if condition to your job to run only if the github.actor from the Github context isn't among a list of users you set.
Example with your workflow:
on: [pull_request]
jobs:
build:
name: Comment a pull_request
runs-on: ubuntu-latest
if: ${{ github.actor != 'Slava' }}
steps:
- name: Checkout
uses: actions/checkout#v2
- name: Comment a pull_request
uses: mb2dev/github-action-comment-pull-request#1.0.0
with:
message: "Hello, Thank you for this PR!"
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
This also work for many users if you add && or || inside the condition.
For example, I use this workflow with some of my repositories to add PR comments:
name: PR Comment
on:
pull_request_target:
types:
- opened
jobs:
PR-Comment:
if: github.actor != 'user1' && github.actor != 'user2' && github.actor != 'user3' && github.actor != 'user4' && github.actor != 'user5'
runs-on: ubuntu-latest
steps:
- name: PR Comment
uses: actions/github-script#v2
with:
github-token: ${{secrets.GITHUB_TOKEN}}
script: |
github.issues.createComment({
issue_number: ${{ github.event.number }},
owner: context.repo.owner,
repo: context.repo.repo,
body: ':warning: Have you followed the [contributions guidance](<contribution_guidance_url>)? Content PRs should generally be made against the the [source repo](https://github.com/<owner>/<repo>).'
})

I don't think it's possible to use or inform the Github Team directly with a condition yet.
