aiautocommit 0.10.4

AI generated commit messages

aiautocommit

Generate intelligent commit messages using AI. aiautocommit analyzes your staged changes and creates conventional commit messages, handling both small tweaks and large changesets effectively.

Yes, there are a lot of these. Main ways this is different:

• Simple codebase. < 400 LOC and most of it is prompts and comments.
• Ability to easily customize prompts on a per-repo basis

Installation

pip install aiautocommit

Features

• Generates conventional commit messages
• Customizable prompts and exclusions
• Pre-commit hook integration
• Supports custom config directories
• Does not generate a commit during a merge or reversion (when an existing autogen'd msg exists)

Getting Started

Set your OpenAI API key:

export OPENAI_API_KEY=<YOUR API KEY>

Stage your changes and run aiautocommit:

git add .

# this will generate a commit message and commit the changes
aiautocommit commit

# or, just to see what it will do
aiautocommit commit --print-message

Using the CLI directly is the best way to debug and tinker with the project as well.

Customization

Logging

First, you'll want to enable logging so you can extract the diff and prompt and iterate on it in ChatGPT:

export AIAUTOCOMMIT_LOG_LEVEL=DEBUG
export AIAUTOCOMMIT_LOG_FILE=aiautocommit.log

Now, you'll have a nice log you can tail and fiddle with from there.

Using Config Directory

aiautocommit looks for configuration files in these locations (in priority order):

• .aiautocommit/ in current directory
• $XDG_CONFIG_HOME/aiautocommit/ (defaults to ~/.config/aiautocommit/)
• Custom path via aiautocommit_CONFIG environment variable

To get started with customization:

aiautocommit dump-prompts

This creates a .aiautocommit/ directory with:

• diff_prompt.txt: Template for generating diff summaries
• commit_prompt.txt: Template for generating commit messages
• exclusions.txt: List of files to exclude from processing
• commit_suffix.txt: Static suffix to append to commit messages. Useful for trailers.

Installing Pre-commit Hook

To automatically generate commit messages during git commits:

aiautocommit install-pre-commit

Lefthook Configuration

Lefthook is an excellent tool for managing git hooks. To use aiautocommit with lefthook, add the following to your .lefthook.yml:

prepare-commit-msg:
  commands:
    aiautocommit:
      run: aiautocommit commit --output-file "{1}"
      interactive: true
      env:
        # without this, lefthook will run in an infinite loop
        LEFTHOOK: 0
        # ensures that LOG_LEVEL config of the current project does not interfere with aiautocommit
        LOG_LEVEL: info
        OPENAI_LOG: warn
      skip:
        merge:
        rebase:
        # only run this if the tool exists
        run: ! which aiautocommit > /dev/null

Environment Variables

• OPENAI_API_KEY: Your OpenAI API key
• AIAUTOCOMMIT_OPENAI_API_KEY: Unique API key for OpenAI, overrides OPENAI_API_KEY (useful for tracking or costing purposes)
• AIAUTOCOMMIT_MODEL: AI model to use (default: gpt-4-mini)
• AIAUTOCOMMIT_CONFIG: Custom config directory path
• LOG_LEVEL: Logging verbosity
• AIAUTOCOMMIT_LOG_PATH: Custom log file path

Privacy Disclaimer

gpt-commit uses the OpenAI API to generate commit messages. Both file names and contents from files that contain staged changes will be shared with OpenAI when using gpt-commit. OpenAI will process this data according to their terms of use and API data usage policies. On March 1st 2023 OpenAI pledged that by default, they would not use data submitted by customers via their API to train or improve their models, and that this data will be retained for a maximum of 30 days, after which it will be deleted.

Special Thanks

This project inspired this project. It had a very simple codebase. I've taken the idea and expanded it to include a lot more features, specifically per-project prompt customization.
