GPT-PR is an open-source command-line tool designed to streamline your GitHub workflow for opening PRs. Leveraging OpenAI's ChatGPT API, it automatically opens a GitHub Pull Request with a predefined description and title directly from your current project directory.

For a more detailed explanation, see Installation and Configuration.

pip install -U gpt-pr

If you don't have the pip command available, follow these instructions to install it on different platforms.

1. Go to OpenAI API Keys and generate a new key.
2. Run the following command to fill your key in GPT-PR (it will be stored in ~/.gpt-pr.ini):

gpt-pr-config set openai_api_key MY-API-KEY-VALUE

1. Go to GitHub Settings, choose Generate new token (classic), and select all permissions under repo (full control of private repositories).
2. Run the following command to fill your GH token (it will also be stored in ~/.gpt-pr.ini):

gpt-pr-config set gh_token MY-GH-TOKEN-VALUE

1. Make your changes, commit them, and push to origin (important!).
2. Run the following command in your project directory:

gpt-pr

3. Answer the questions. At the end, you'll receive the URL of a freshly opened PR.

• 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.

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

• Python 3.7 or higher
• Pipenv

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

1. Install OR Update the package:

pip install -U gpt-pr

2. Setup API keys for GitHub and OpenAI, take a look at Configuration.

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

gpt-pr --help

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 setting up API keys (Configuration), 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

To print all default configs and what is being used, just run:

gpt-pr-config print

GPT-PR tool will look for a GH_TOKEN in current shell env var OR in gpt-pr config file (at ~/.gpt-pr.ini).

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. Set gh_token config running (supposing your gh token is ghp_4Mb1QEr9gY5e8Lk3tN1KjPzX7W9z2V4HtJ2b):

gpt-pr-config set gh_token ghp_4Mb1QEr9gY5e8Lk3tN1KjPzX7W9z2V4HtJ2b

Or just export it as an environment variable in your shell initializer:

export GH_TOKEN=your_generated_token_here

GPT-PR tool will look for a OPENAI_API_KEY env var in current shell OR in gpt-pr config file (at ~/.gpt-pr.ini).

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. Set openai_api_key config running (supposing your openai_api_key is QEr9gY5e8Lk3tN1KjPzX7W9z2V4Ht):

gpt-pr-config set openai_api_key QEr9gY5e8Lk3tN1KjPzX7W9z2V4Ht

Or just export it as an environment variable in your shell initializer:

export OPENAI_API_KEY=your_generated_api_key_here

You can adjust the maximum number of input tokens allowed when calling the LLM model by modifying the corresponding setting.

For example, to change the maximum to 20,000 tokens, use the following command:

gpt-pr-config set input_max_tokens 20000

To change OpenAI model, just run:

gpt-pr-config set openai_model gpt-4o-mini

Obs.: gpt-4o-mini already is the default model of the project

To see a full list of available models, access OpenAI Models Documentation

To help other developers recognize and understand the use of the GPT-PR library in generating pull requests, we have included an optional signature feature. By default, this feature is enabled and appends the text "Generated by GPT-PR" at the end of each pull request. This transparency fosters better collaboration and awareness among team members about the tools being utilized in the development process.

If you prefer to disable this feature, simply run the following command:

gpt-pr-config set add_tool_signature false

To reset any config to default value, just run:

gpt-pr-config reset config_name

Example:

gpt-pr-config reset openai_model

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

To show help commands:

gpt-pr -h

Output:

• 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.
