/codex how does the logic of generating replies from comments work?

how does the logic of generating replies from comments work?

@jjranalli When a comment is created on a pull request with the text /ask-codex, the replyIssueComment function is triggered. It first extracts the relevant information from the payload, such as the repository, issue, sender, and comment. Then it gets the diff content using the getCodeDiff function, which retrieves the diff of the pull request using the GitHub API.

If there are changes in the diff, generateChatGpt is called with a system prompt and the code diff as messages. generateChatGpt uses OpenAI's GPT-3 API to generate a response to the question asked in the comment.

Finally, the response is formatted as a comment and posted back to the pull request as a reply to the original comment. In addition, if there are skipped files or if the code diff exceeds the maximum character limit, this information is appended to the response.

   • Corresponding changes in function calls to use the new payload.

   • Added logic to respond to comments created on pull requests, specifically if they contain the command /ask-codex.

6. New Functionality in utils/getCodeDiff.ts:

   • A new function getCodeDiff has been added to fetch and parse the diff content from GitHub pull requests.

7. New File utils/github/testPayloadSyncPr.ts:

   • This file includes a new payload structure for handling synchronized pull requests.

   • A function to reply to issue comments based on the content of the comments and the associated pull request.

9. Changes in lib/summarizePullRequest.ts:
