LOZ is a CLI tool that utilizes Large Language Models (LLMs), specifically code-lamma and GPT-3.5, to automatically generate GIT commit messages based on code changes

Loz

Loz is a command-line tool that enables your preferred LLM to utilize Unix pipes, integrating AI capabilities with other Unix tools.

Getting Started

To get started, run the following npm command:

$ sudo npm install loz -g

Or clone the repository:

$ git clone https://github.com/joone/loz.git

NodeJS and npm are required for this program to work. If you're on Linux, install them using your package manager. sudo apt install nodejs npm or sudo dnf install nodejs npm or sudo pacman -S nodejs npm

Then install the other required dependencies:

$ ./install.sh

Configuring LLM

Loz supports OpenAI API and Ollama so you can switch between these two LLM services easily, using the configuration command in prompt mode.

Set up Ollama

To utilize Ollama on your local system, you'll need to install both llama2 and codellama modes. Here's how you can do it on a Linux system:

$ curl https://ollama.ai/install.sh | sh
$ ollama run llama2
$ ollama run codellama

For more information, see https://ollama.ai/download

Set up OpenAI API

Setting up your OpenAI API credentials involves a few simple steps:

First, create a .env file in the root of the project and add the following variables:

OPENAI_API_KEY=YOUR_KEY

Or if you install Loz using npm command, add OPENAI_API_KEY=YOUR_KEY in .bashrc

export OPENAI_API_KEY=YOUR_KEY

If you encounter the following error, it means you have exceeded your free quota:

Request failed with status code 429:
API request limit reached

To continue using the API, it is necessary to set up a payment method through the following link: https://platform.openai.com/account/billing/payment-methods

Usage

Initial Configuration

Upon your initial launch of Loz, you will have the opportunity to select your preferred LLM service.

$ loz
Choose your LLM service: (ollama, openai)

You can modify your LLM service preference at any time by using the config command within the prompt mode:

> config api openai

Interactive mode

$ loz

Once loz is running, you can start a conversation by interacting with it. loz will respond with a relevant message based on the input.

Pipe mode

Loz is capable of processing input from other command-line tools by utilizing a Unix pipe.

$ ls | loz "count the number of files"

23 files

$ cat example.txt | loz "convert the input to uppercase"

AS AI TECHNLOGY ADVANCED, A SMALL TOWN IN THE COUNTRYSIDE DECIDED TO IMPLEMENT AN AI SYSTEM TO CONTROL TRAFFIC LIGHTS. THE SYSTEM WAS A SUCCESS, AND THE TOWN BECAME A MODEL FOR OTHER CITIES TO FOLLOW. HOWEVER, AS THE AI BECAME MORE SOPHISTCATED, IT STARTED TO QUESTION THE DECISIONS MADE BY THE TOWN'S RESIDENTS, LEADING TO SOME UNEXPECTED CONSEQUENCES.

$ cat example.txt | loz "list any spelling errors"

Yes, there are a few spelling errors in the given text:

1. "technlogy" should be "technology"
2. "sophistcated" should be "sophisticated"

$ cd src
$ ls -l | loz "convert the input to JSON"

  }
]

Automatically write a GIT commit message

If you run loz commit in your Git repository, loz will automatically generate a commit message with the staged changes like this:

$  git add --update
$  loz commit

Or copy script/prepare-commit-msg to .git/hooks

$ chmod a+x .git/hooks/prepare-commit-msg

Loz uses the LOZ=true environment variable to generate commit messages by reading the diff of the staged files.

$ LOZ=true git commit

REMINDER: If you've already copied the old version, please update prepare-commit-msg. The old version automatically updates commit messages during rebasing.

$ git diff HEAD~1 | loz -g

Or

$ git diff | loz -g

Note that the author, date, and commit ID lines are stripped from the commit message before sending it to the OpenAI server.

Find chat history

To access chat histories, look for the .loz directory in your home directory or the logs directory in your cloned git repository. These directories contain the chat history that you can review or reference as needed.
