GPTComet is an AI-powered developer tool that streamlines your Git workflow and enhances code quality through automated commit message generation and intelligent code review.

This project leverages the power of large language models to automate repetitive tasks and improve the overall development process. The core features include:

• Automatic Commit Message Generation: GPTComet can generate commit messages based on the changes made in the code.
• Support for Multiple Languages: GPTComet supports multiple languages, including English, Chinese and so on.
• Customizable Configuration: GPTComet allows users to customize the configuration to suit their needs, such llm model and prompt.
• Support for Rich Commit Messages: GPTComet supports rich commit messages, which include a title, summary, and detailed description.
• Support for Multiple Providers: GPTComet supports multiple providers, including OpenAI, Gemini, Claude/Anthropic, Vertex, Azure, Ollama, and others.
• Support SVN and Git: GPTComet supports both SVN and Git repositories.

To use GPTComet, you can download from Github release, or by install scripts:

curl -sSL https://cdn.jsdelivr.net/gh/belingud/gptcomet@master/install.sh | bash

Windows:

irm https://cdn.jsdelivr.net/gh/belingud/gptcomet@master/install.ps1 | iex

If you want to install specific version, you can use the following script:

curl -sSL https://cdn.jsdelivr.net/gh/belingud/gptcomet@master/install.sh | bash -s -- -v 0.4.2

irm https://cdn.jsdelivr.net/gh/belingud/gptcomet@master/install.ps1 | iex -CommandArgs @("-v", "0.4.2")

If you prefer to run in python, you can install by pip directly, it packaged the binary files corresponding to the platform already.

pip install gptcomet

# Using pipx
pipx install gptcomet

# Using uv
uv tool install gptcomet
Resolved 1 package in 1.33s
Installed 1 package in 8ms
 + gptcomet==0.1.6
Installed 2 executables: gmsg, gptcomet

To use gptcomet, follow these steps:

1. Install GPTComet: Install GPTComet through pypi.
2. Configure GPTComet: See Setup. Configure GPTComet with your api_key and other required keys like:

• provider: The provider of the language model (default openai).
• api_base: The base URL of the API (default https://api.openai.com/v1).
• api_key: The API key for the provider.
• model: The model used for generating commit messages (default gpt-4o).

3. Run GPTComet: Run GPTComet using the following command: gmsg commit.

If you are using openai provider, and finished set api_key, you can run gmsg commit directly.

1. Direct Configuration

   • Configure directly in ~/.config/gptcomet/gptcomet.yaml.

2. Interactive Setup

   • Use the gmsg newprovider command for guided setup.

Here's a summary of the main configuration keys:

Note: <provider> should be replaced with the actual provider name (e.g., openai, gemini, claude).

Some providers require specific keys, such as Vertex needing project ID, location, etc.

The configuration file for GPTComet is gptcomet.yaml. The file should contain the following keys:

output.translate_title is used to determine whether to translate the title of the commit message.

For example in output.lang: zh-cn, the title of the commit message is feat: Add new feature

If output.translate_title is set to true, the commit message will be translated to 功能：新增功能. Otherwise, the commit message will be translated to feat: 新增功能.

In some case you can set complation_path to empty string, like <provider>.completion_path: "", to use api_base endpoint directly.

The file to ignore when generating a commit. The default value is

- bun.lockb
- Cargo.lock
- composer.lock
- Gemfile.lock
- package-lock.json
- pnpm-lock.yaml
- poetry.lock
- yarn.lock
- pdm.lock
- Pipfile.lock
- "*.py[cod]"
- go.sum
- uv.lock

You can add more file_ignore by using the gmsg config append file_ignore <xxx> command. <xxx> is same syntax as gitignore, like *.so to ignore all .so suffix files.

The provider configuration of the language model.

The default provider is openai.

Provider config just like:

provider: openai
openai:
    api_base: https://api.openai.com/v1
    api_key: YOUR_API_KEY
    model: gpt-4o
    retries: 2
    max_tokens: 1024
    temperature: 0.7
    top_p: 0.7
    frequency_penalty: 0
    extra_headers: {}
    answer_path: choices.0.message.content
    completion_path: /chat/completions

If you are using openai, just leave the api_base as default. Set your api_key in the config section.

If you are using an openai class provider, or a provider compatible interface, you can set the provider to openai. And set your custom api_base, api_key and model.

For example:

Openrouter providers api interface compatible with openai, you can set provider to openai and set api_base to https://openrouter.ai/api/v1, api_key to your api key from keys page and model to meta-llama/llama-3.1-8b-instruct:free or some other you prefer.

gmsg config set openai.api_base https://openrouter.ai/api/v1
gmsg config set openai.api_key YOUR_API_KEY
gmsg config set openai.model meta-llama/llama-3.1-8b-instruct:free
gmsg config set openai.max_tokens 1024

Silicon providers the similar interface with openrouter, so you can set provider to openai and set api_base to https://api.siliconflow.cn/v1.

Note that max tokens may vary, and will return an error if it is too large.

The output configuration of the commit message.

The default output is

output:
    lang: en
    rich_template: "<title>:<summary>\n\n<detail>"
    translate_title: false
    review_lang: "en"
    markdown_theme: "auto"

You can set rich_template to change the template of the rich commit message, and set lang to change the language of the commit message.

Supported markdown theme:

• auto: Auto detect markdown theme (default).
• ascii: ASCII style.
• dark: Dark theme.
• dracula: Dracula theme.
• light: Light theme.
• tokyo-night: Tokyo Night theme.
• notty: Notty style, no render.
• pink: Pink theme.

If you not set markdown_theme, the markdown theme will be auto detected. If you are using light terminal, the markdown theme will be dark, if you are using dark terminal, the markdown theme will be light.

GPTComet is using glamour to render markdown, you can preview the markdown theme in glamour preview.

output.lang and output.review_lang support the following languages:

• en: English
• zh-cn: Simplified Chinese
• zh-tw: Traditional Chinese
• fr: French
• vi: Vietnamese
• ja: Japanese
• ko: Korean
• ru: Russian

The console output config.

The default console is

console:
    verbose: true

When verbose is true, more information will be printed in the console.

You can use gmsg config keys to check supported keys.

Here is an example of how to use GPTComet:

1. When you first set your OpenAI KEY by gmsg config set openai.api_key YOUR_API_KEY, it will generate config file at ~/.local/gptcomet/gptcomet.yaml, includes:

provider: "openai"
openai:
  api_base: "https://api.openai.com/v1"
  api_key: "YOUR_API_KEY"
  model: "gpt-4o"
  retries: 2
output:
  lang: "en"

2. Run the following command to generate a commit message: gmsg commit
3. GPTComet will generate a commit message based on the changes made in the code and display it in the console.

Note: Replace YOUR_API_KEY with your actual API key for the provider.
