Features

• Analyzes the diff changes of the current branch against the main branch.
• Provides an option to exclude certain file changes from PR generation (for instance, you can ignore a package.lock file with 5k lines changed).
• Incorporates commit messages into the process.

Prerequisites

Before getting started, make sure you have the following installed:

• Python 3.7 or higher
• Pipenv

Installation

You can install and use GPT-PR in one of two ways. Choose the option that best suits your needs.

Option 1: Using pip install (Recommended)

1. Install the package:

pip install -U gpt-pr

Note: Use this command to update gpt-pr package to the latest version.

2. Export API keys as environment variables (Authentication & API Keys).

3. Inside the Git repository you are working on, ensure you have pushed your branch to origin, then run:

gpt-pr --help

Option 2: Cloning the code

1. Clone the repository:

git clone https://github.com/alissonperez/gpt-pr.git

2. Navigate to the project directory and install dependencies:

cd gpt-pr
pipenv install

After exporting api keys as environment variables (Authentication & API Keys), you can use GPT-PR within any git project directory. Suppose you've cloned this project to ~/workplace/gpt-pr, here's how you can use it:

PYTHONPATH=~/workplace/gpt-pr/gpt-pr \
PIPENV_PIPFILE=~/workplace/gpt-pr/Pipfile \
pipenv run python ~/workplace/gpt-pr/gptpr/main.py --help

Usage

Generating Github Pull Requests

To create a Pull request from your current branch commits to merge with main branch, just run:

gpt-pr

If you would like to compare with other base branch that is not main, just use -b param:

gpt-pr -b my-other-branch

Usage help

To show help commands:

gpt-pr -h

Authentication & API Keys

Setting up GitHub Token (GH_TOKEN)

To authenticate with GitHub, generate and export a GitHub Personal Access Token:

1. Navigate to GitHub's Personal Access Token page.
2. Click "Generate new token."
3. Provide a description and select the required permissions repo for the token.
4. Click "Generate token" at the bottom of the page.
5. Copy the generated token.
6. Export it as an environment variable:

export GH_TOKEN=your_generated_token_here

Setting up OpenAI API Key (OPENAI_API_KEY)

This project needs to interact with the ChatGPT API to generate the pull request description. So, you need to generate and export an OpenAI API Key:

1. Navigate to OpenAI's API Key page.
2. If you don't have an account, sign up and log in.
3. Go to the API Keys section and click "Create new key."
4. Provide a description and click "Create."
5. Copy the generated API key.
6. Export it as an environment variable:

export OPENAI_API_KEY=your_generated_api_key_here

Roadmap

• Improve execution method, possibly through a shell script or at least an alias in bash rc files.
  • Change to use with pip installation and console_scripts entry point.
• Fetch GitHub PR templates from the current project.
• Add configuration to set which LLM and model should be used (OpenAI GPT, Mistral, etc...)
• Add unit tests.
