| # This workflow checks for any changes in .qhelp files in pull requests. | |
| # For any changed files, it renders them to markdown in a file called `comment_body.txt`. | |
| # It then checks if there's an existing comment on the pull request generated by | |
| # this workflow, and writes the comment ID to `comment_id.txt`. | |
| # It also writes the PR number to `pr_number.txt`. | |
| # These three files are uploaded as an artifact. | |
| # When this workflow completes, the workflow "Post PR comment" runs. | |
| # It downloads the artifact and adds a comment to the PR with the rendered | |
| # QHelp. | |
| # The task is split like this because creating PR comments requires extra | |
| # permissions that we don't want to expose to PRs from external forks. | |
