Automatically assigns GitHub issues to the creator or a commenter based on specific keywords.

About This Workflow

This workflow automates the process of assigning GitHub issues. It listens for new issues and comments on issues. If an issue is opened and has no assignee, it assigns the issue creator. If a comment is made on an issue and contains the phrase 'assign me', it checks if the issue is already assigned. If not, it assigns the commenter.

Key Features

Triggers on GitHub issue and issue_comment events.
Routes workflows based on issue action (opened, created).
Checks if an issue has assignees.
Detects 'assign me' keywords in issue body and comments.
Assigns the issue creator to newly opened, unassigned issues.
Assigns a commenter to an issue if they request it and the issue is unassigned.
Adds a 'assigned' label to issues upon assignment.
Adds a comment to an issue if a user requests assignment but the issue is already assigned to someone else.

How To Use

Trigger: The workflow starts with a Github Trigger1 node, configured to listen for issue_comment and issues events in a specific repository.
Action Switch: A Switch node determines the action based on the GitHub event's action field. It routes to different paths for 'opened' or 'created' issue events, and for comment-related events.
**Issue Opened/Created Logic:
- IF no assignee? This IF node checks two conditions:
  - If the assignees array of the issue is empty (.length equals 0).
  - If the body of the issue contains the regex /^[a,A]ssign[\w*\s*]*me/gm (a case-insensitive check for 'assign me' or similar phrases).
- If both conditions are met, the Assign Issue Creator node is triggered. This node uses the GitHub API to edit the issue, adding the issue's creator as an assignee and applying the 'assigned' label.
- If the conditions are not met, a NoOp node is used to do nothing.
**Comment Logic:
- IF wants to work? This IF node checks if the body of the comment contains the regex /^[a,A]ssign[\w*\s*]*me/gm.
- If the comment indicates a desire to work on the issue, it then proceeds to the IF not assigned? node.
- IF not assigned? This IF node checks if the assignees array of the issue is empty.
  - If the issue has no assignees, the Assign Commenter node is triggered. This node assigns the commenter to the issue and adds the 'assigned' label.
  - If the issue already has assignees, the Add Comment node is triggered. This node posts a message to the issue informing the commenter that the issue is already assigned.
- If the comment does not indicate a desire to work on the issue, a NoOp1 node is used to do nothing.
