Comment Pull Request - GitHub Actions

What is it ?

A GitHub action that comments with a given message the pull request linked to the pushed branch.
You can even put dynamic data thanks to Contexts and expression syntax.

Usage

Classic usage

on: pull_request

jobs:
  example_comment_pr:
    runs-on: ubuntu-latest
    name: An example job to comment a PR
    steps:
      - name: Checkout
        uses: actions/checkout@v3

      - name: Comment PR
        uses: thollander/actions-comment-pull-request@v2
        with:
          message: |
            Hello world ! :wave:

Comment a file content

Thanks to the filePath input, a file content can be commented.
You can either pass an absolute filePath or a relative one that will be by default retrieved from GITHUB_WORKSPACE.
(Note that if both a message and filePath are provided, message will take precedence.)

- name: PR comment with file
  uses: thollander/actions-comment-pull-request@v2
  with:
    filePath: /path/to/file.txt

Setting reactions

You can also set some reactions on your comments through the reactions input.
It takes only valid reactions and adds it to the comment you've just created. (See https://docs.github.com/en/rest/reactions#reaction-types)

- name: PR comment with reactions
  uses: thollander/actions-comment-pull-request@v2
  with:
    message: |
      Hello world ! :wave:
    reactions: eyes, rocket

Specifying which pull request to comment on

You can explicitly input which pull request should be commented on by passing the pr_number input.
That is particularly useful for manual workflow for instance (workflow_run).

...
- name: Comment PR
  uses: thollander/actions-comment-pull-request@v2
  with:
    message: |
      Hello world ! :wave:
    pr_number: 123 # This will comment on pull request #123

Update a comment

Editing an existing comment is also possible thanks to the comment_tag input.

Thanks to this parameter, it will be possible to identify your comment and then to upsert on it.
If the comment is not found at first, it will create a new comment.

That is particularly interesting while committing multiple times in a PR and that you just want to have the last execution report printed. It avoids flooding the PR.

...
- name: Comment PR with execution number
  uses: thollander/actions-comment-pull-request@v2
  with:
    message: |
      _(execution **${{ github.run_id }}** / attempt **${{ github.run_attempt }}**)_
    comment_tag: execution

Note: the input mode can be used to either upsert (by default) or recreate the comment (= delete and create)

Delete a comment

Deleting an existing comment is also possible thanks to the comment_tag input combined with mode: delete.

This will delete the comment at the end of the job.

...
- name: Write a comment that will be deleted at the end of the job
  uses: thollander/actions-comment-pull-request@v2
  with:
    message: |
      The PR is being built...
    comment_tag: to_delete
    mode: delete

Inputs

Action inputs

Name	Description	Required	Default
GITHUB_TOKEN	Token that is used to create comments. Defaults to ${{ github.token }}	✅
message	Comment body
filePath	Path of the file that should be commented
reactions	List of reactions for the comment (comma separated). See https://docs.github.com/en/rest/reactions#reaction-types
pr_number	The number of the pull request where to create the comment		current pull-request/issue number (deduced from context)
comment_tag	A tag on your comment that will be used to identify a comment in case of replacement
mode	Mode that will be used to update comment (upsert/recreate/delete)		upsert
create_if_not_exists	Whether a comment should be created even if comment_tag is not found		true

Permissions

Depending on the permissions granted to your token, you may lack some rights.
To run successfully, this actions needs at least :

permissions: 
   pull-requests: write 

Add this in case you get Resource not accessible by integration error.
See jobs.<job_id>.permissions for more information.

Note that, if the PR comes from a fork, it will have only read permission despite the permissions given in the action for the pull_request event.
In this case, you may use the pull_request_target event. With this event, permissions can be given without issue (the difference is that it will execute the action from the target branch and not from the origin PR).
