gen-commit 1.0.0

Auto-generate git commit messages

Gen Commit

Gen Commit uses LLMs to automatically generate git commit messages. I'm lazy and don't like to write commit messages. Inspired by scommit.

---

Usage

gencommit works exactly like git commit, but it generates the commit message and description for you.

gencommit

is the same as

git commit -m "..." -m "..."

but with a generated commit message.

You can also pass in the same arguments as git commit.

gencommit -a

is the same as

git commit -a -m "..." -m "..."

I recommend aliasing it, personally I alias it to gc. You can do this by adding the following to your shell configuration file (.zshrc, .bashrc, etc.)

alias gc="gencommit"

Installation

Recommended: Homebrew (macOS and Linux)

brew tap raghavpillai/gen-commit
brew install gen-commit

Python

Prerequisites:

• Python 3.11+

Install the gen-commit package using pip:

pip install gen-commit

If you get

error: externally-managed-environment

This means Python now doesn't want you to install this as a system-wide package. You can install it using pipx or venv, or be lazy and install it via:

pip3 install gen-commit --break-system-packages

Initialization

Once you have it installed, initialize gencommit

gencommit --init

Go to ~/.gen-commit and add your OpenAI, Anthropic, or Google API key.
