Loz is a command-line interface tool based on OpenAI API that allows Unix pipes to be used with other Unix tools.

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

Next, configure your OpenAPI credentials. You will need to 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

$ 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.

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 all characters in the following text to their 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 "please proofread the following text and list up any spelling errors: "

Spelling errors:
- technlogy  (technology)
- sophistcated (sophisticated)

$ cd src
$ ls -l | loz "convert the ls output to JSON format: "

  }
]

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.

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.
