Comment

Comment a pull request.


The comment action allows Mergify to post a comment on your pull request when certain conditions are met.

The comment action is a powerful tool that can provide automated responses to various events in your pull request workflow. By customizing the conditions and the message, you can create a more interactive and responsive experience for your contributors.

Key nameValue type
bot_account

template

Mergify can impersonate a GitHub user to comment a pull request. If no bot_account is set, Mergify will comment the pull request itself.

message

template

The message to write as a comment.

In this example, Mergify will post the message “Thank you for your contribution! A reviewer will be assigned soon.” when a pull request is labeled with “needs review”.

pull_request_rules:
  - name: comment when a pull request is labeled "needs review"
    conditions:
      - label=needs review
    actions:
      comment:
        message: Thank you for your contribution! A reviewer will be assigned soon.

Warn of Conflicting Pull Requests

Section titled Warn of Conflicting Pull Requests

When a pull request is in conflict and cannot be merged, it’s nice to be notified automatically by Mergify. You can do this using this rule:

pull_request_rules:
  - name: comment when a pull request is merged
    conditions:
      - conflict
    actions:
      comment:
        message: @{{author}} Your PR is in conflict and cannot be merged.

In this example, Mergify will post the message “Thank you for your contribution! Your pull request has been merged.” when a pull request is merged.

pull_request_rules:
  - name: comment when a pull request is merged
    conditions:
      - merged
    actions:
      comment:
        message: Thank you for your contribution @{{author}}! Your pull request has been merged.
