ChatGPT PR Reviewer

ChatGPT PR Reviewer is a Go-based command-line tool that integrates with GitHub and OpenAI's ChatGPT to perform automated code reviews on pull requests (PRs). The tool fetches changes from a specified PR, sends the modified code blocks to ChatGPT for review, and posts the feedback as comments on the PR.

Features

• Fetches pull request changes from a GitHub repository.
• Sends modified code blocks to ChatGPT for review.
• Posts ChatGPT's feedback as comments on the pull request.

Prerequisites

• Go 1.22 or later
• A GitHub account with a personal access token.
• An OpenAI account with API access.

Installation

1. Install the CLI Tool

   Use the following command to install the review CLI tool:

   go install github.com/ozgen/go-chatgpt-pr-reviewer/cmd/review@v1.0.4

This will download and build the CLI tool, placing the review binary in your GOPATH/bin or GOBIN directory.

2. Set Environment Variables

   Before running the tool, you need to set the following environment variables:

   export OPENAI_API_KEY=<your_openai_api_key>
   export ORGANIZATION_ID=<your_organization_id>
   export PROJECT_ID=<your_project_id>
   export GITHUB_TOKEN=<your_github_token>

   • OPENAI_API_KEY: Your OpenAI API key.
   • ORGANIZATION_ID: Your OpenAI organization ID.
   • PROJECT_ID: Your OpenAI project ID.
   • GITHUB_TOKEN: Your GitHub personal access token with repo scope.

Usage

Once installed, you can use the review command to perform a code review on a pull request:

review --local "/path/to/local/repo" --pr 1 [--post-comments]

• --local specifies the path to your local Git repository.
• --pr specifies the pull request number you want to review.

Example

1. Set Environment Variables:

   export OPENAI_API_KEY=sk-...
   export ORGANIZATION_ID=org-...
   export PROJECT_ID=proj-...
   export GITHUB_TOKEN=ghp_...

2. Run the Review Command:

   To run the review without posting comments (default behavior):

   review --local "/Users/ozgen/Desktop/checkstyle-runner" --pr 1

To run the review and post comments to GitHub:

review --local "/Users/ozgen/Desktop/checkstyle-runner" --pr 1 --post-comments 

This command will fetch the changes from PR #1 in the specified local repository, send the changes to ChatGPT for review, and post the feedback as comments on the PR.
