AICommit2

A Reactive CLI that generates git commit messages with Ollama, ChatGPT, Gemini, Claude, Mistral and other AI

Introduction

aicommit2 is a reactive CLI tool that automatically generates Git commit messages using various AI models. It supports simultaneous requests to multiple AI providers, allowing users to select the most suitable commit message. The core functionalities and architecture of this project are inspired by AICommits.

Key Features

Multi-AI Support: Integrates with OpenAI, Anthropic Claude, Google Gemini, Mistral AI, Cohere, Groq, Huggingface, and Ollama for local models.
Local Model Support: Use local AI models via Ollama.
Reactive CLI: Enables simultaneous requests to multiple AIs and selection of the best commit message.
Git Hook Integration: Can be used as a prepare-commit-msg hook.
Custom Prompts: Supports user-defined prompt templates.

Supported Providers

Ollama

Setup

The minimum supported version of Node.js is the v18. Check your Node.js version with node --version.

Install aicommit2:

npm install -g aicommit2

Retrieve and set API keys or Cookie you intend to use:

It is not necessary to set all keys. But at least one key must be set up.

OpenAI

aicommit2 config set OPENAI_KEY=<your key>

Anthropic Claude

aicommit2 config set ANTHROPIC_KEY=<your key>

Gemini

aicommit2 config set GEMINI_KEY=<your key>

Mistral AI

aicommit2 config set MISTRAL_KEY=<your key>

Codestral

aicommit2 config set CODESTRAL_KEY=<your key>

Cohere

aicommit2 config set COHERE_KEY=<your key>

Groq

aicommit2 config set GROQ_KEY=<your key>

Huggingface (Unofficial)

# Please be cautious of Escape characters(\", \') in browser cookie string 
aicommit2 config set HUGGINGFACE_COOKIE="<your browser cookie>"

This will create a .aicommit2 file in your home directory.

You may need to create an account and set up billing.

Run aicommit2 with your staged files in git repository:

git add <files...>
aicommit2

Using Locally

You can also use your model for free with Ollama and it is available to use both Ollama and remote providers simultaneously.

Install Ollama from https://ollama.com
Start it with your model

ollama run llama3 # model you want use. ex) codellama, deepseek-coder

Set the model and host

aicommit2 config set OLLAMA_MODEL=<your model>

If you want to use ollama, you must set OLLAMA_MODEL.

Run aicommit2 with your staged in git repository

git add <files...>
aicommit2

👉 Tip: Ollama can run LLMs in parallel from v0.1.33. Please see this section.

How it works

This CLI tool runs git diff to grab all your latest code changes, sends them to configured AI, then returns the AI generated commit message.

If the diff becomes too large, AI will not function properly. If you encounter an error saying the message is too long or it's not a valid commit message, try reducing the commit unit.

Usage

CLI mode

You can call aicommit2 directly to generate a commit message for your staged changes:

git add <files...>
aicommit2

aicommit2 passes down unknown flags to git commit, so you can pass in commit flags.

For example, you can stage all changes in tracked files with as you commit:

aicommit2 --all # or -a

👉 Tip: Use the aic2 alias if aicommit2 is too long for you.

CLI Options

`--locale` or `-l`

Locale to use for the generated commit messages (default: en)

aicommit2 --locale <s> # or -l <s>

`--generate` or `-g`

Number of messages to generate (Warning: generating multiple costs more) (default: 1)
Sometimes the recommended commit message isn't the best so you want it to generate a few to pick from. You can generate multiple commit messages at once by passing in the --generate <i> flag, where 'i' is the number of generated messages:

aicommit2 --generate <i> # or -g <i>

Warning: this uses more tokens, meaning it costs more.

`--all` or `-a`

Automatically stage changes in tracked files for the commit (default: false)

aicommit2 --all # or -a

`--type` or `-t`

Automatically stage changes in tracked files for the commit (default: conventional)
it supports conventional and gitmoji

aicommit2 --type conventional # or -t conventional
aicommit2 --type gitmoji # or -t gitmoji

`--confirm` or `-y`

Skip confirmation when committing after message generation (default: false)

aicommit2 --confirm # or -y

`--clipboard` or `-c`

Copy the selected message to the clipboard (default: false)
This is a useful option when you don't want to commit through aicommit2.
If you give this option, aicommit2 will not commit.

aicommit2 --clipboard # or -c

`--promptPath` or `-p`

Allow users to specify a custom file path for their own prompt template
Enable users to define and use their own prompts instead of relying solely on the default prompt
Please see Custom Prompt Template

aicommit2 --promptPath <s> # or -p <s>

Git hook

You can also integrate aicommit2 with Git via the prepare-commit-msg hook. This lets you use Git like you normally would, and edit the commit message before committing.

Install

In the Git repository you want to install the hook in:

aicommit2 hook install

Uninstall

In the Git repository you want to uninstall the hook from:

aicommit2 hook uninstall

Usage

Stage your files and commit:

git add <files...>
git commit # Only generates a message when it's not passed in

If you ever want to write your own message instead of generating one, you can simply pass one in: git commit -m "My message"

aicommit2 will generate the commit message for you and pass it back to Git. Git will open it with the configured editor for you to review/edit it.
Save and close the editor to commit!

Configuration

Reading a configuration value

To retrieve a configuration option, use the command:

aicommit2 config get <key>

For example, to retrieve the API key, you can use:

aicommit2 config get OPENAI_KEY

You can also retrieve multiple configuration options at once by separating them with spaces:

aicommit2 config get OPENAI_KEY OPENAI_MODEL GEMINI_KEY

Setting a configuration value

To set a configuration option, use the command:

aicommit2 config set <key>=<value>

For example, to set the API key, you can use:

aicommit2 config set OPENAI_KEY=<your-api-key>

You can also set multiple configuration options at once by separating them with spaces, like

aicommit2 config set OPENAI_KEY=<your-api-key> generate=3 locale=en

Upgrading

Check the installed version with:

aicommit2 --version

If it's not the latest version, run:

npm update -g aicommit2

Custom Prompt Template

aicommit2 supports custom prompt templates through the promptPath option. This feature allows you to define your own prompt structure, giving you more control over the commit message generation process.

Using the promptPath Option

To use a custom prompt template, specify the path to your template file when running the tool:

aicommit2 config set promptPath="/path/to/user/prompt.txt"

Template Format

Your custom template can include placeholders for various commit options. Use curly braces {} to denote these placeholders for options. The following placeholders are supported:

{locale}: The language for the commit message (string)
{maxLength}: The maximum length for the commit message (number)
{type}: The type of the commit (conventional or gitmoji)
{generate}: The number of commit messages to generate (number)

Example Template

Here's an example of how your custom template might look:

Generate a {type} commit message in {locale}.
The message should not exceed {maxLength} characters.
Please provide {generate} messages.

Remember to follow these guidelines:
1. Use the imperative mood
2. Be concise and clear
3. Explain the 'why' behind the change

Appended Text

Please note that the following text will always be appended to the end of your custom prompt:

Provide your response as a JSON array where each element is an object with "subject", "body", and "footer" keys.
The "subject" should include the type, optional scope, and description . If there's no body or footer, use an empty string for those fields.
Example response format:
[
  {
    "subject": "string",
    "body": "string",
    "footer": "string"
  },
]

This ensures that the output is consistently formatted as a JSON array, regardless of the custom template used.

Notes

If the specified file cannot be read or parsed, aicommit2 will fall back to using the default prompt generation logic. Ensure your template includes all necessary instructions for generating appropriate commit messages. You can still use all other command-line options in conjunction with promptPath.

By using custom templates, you can tailor the commit message generation to your team's specific needs or coding standards.

NOTE: For the promptPath option, set the template path, not the template content

Loading Multiple Ollama Models

You can load and make simultaneous requests to multiple models using Ollama's experimental feature, the OLLAMA_MAX_LOADED_MODELS option.

OLLAMA_MAX_LOADED_MODELS: Load multiple models simultaneously

Setup Guide

Follow these steps to set up and utilize multiple models simultaneously:

1. Running Ollama Server

First, launch the Ollama server with the OLLAMA_MAX_LOADED_MODELS environment variable set. This variable specifies the maximum number of models to be loaded simultaneously. For example, to load up to 3 models, use the following command:

OLLAMA_MAX_LOADED_MODELS=3 ollama serve

Refer to configuration for detailed instructions.

2. Configuring aicommit2

Next, set up aicommit2 to specify multiple models. You can assign a list of models, separated by commas(,), to the OLLAMA_MODEL environment variable. Here's how you do it:

aicommit2 config set OLLAMA_MODEL="mistral,dolphin-llama3"

With this command, aicommit2 is instructed to utilize both the "mistral" and "dolphin-llama3" models when making requests to the Ollama server.

3. Run aicommit2

aicommit2

Note that this feature is available starting from Ollama version 0.1.33 and aicommit2 version 1.9.5.
