Jarvis-sh

An AI-powered command-line assistant for your terminal, compatible with both local AI models via Ollama and OpenAI. It not only supports executing commands but also intelligently suggests and finds commands from its own knowledge base or a predefined list, taking your productivity as a developer or DevOps engineer to the next level.

Prerequisites

Before installing Jarvis-sh, ensure you have the following:

Node.js: Version 19 or higher is recommended. This is required for running Jarvis-sh.
Ollama (Optional): If you want to use local open-source AI models, you'll need to install Ollama, a runtime for large language models. You can install it from here.
AI Model (Optional): A local AI model compatible with Ollama. We recommend using llama3.2. Make sure the model is downloaded and available for use.

Installing Ollama

Follow the instructions on the Ollama website to install Ollama on your system.

Installing the AI Model

After installing Ollama, install the llama3.2 model by running:

ollama pull llama3.1:8b

Installation jarvis-sh

Install Jarvis-sh globally using npm:

npm install -g jarvis-sh

This will make the jarvis command available globally on your system.

Configuration

AI Service and Model

You can set up both the AI service and the model using the interactive setup command:

jarvis --setup

This command will guide you through selecting the AI service and model. Currently, we support the following services:

OpenAI
Anthropic
Ollama

For OpenAI and Anthropic, you will need to provide an API key, which you can obtain from the respective provider. For Ollama, the models available are those installed locally, and you can list them using ollama list.

API Key (For OpenAI and Anthropic)

If you choose OpenAI or Anthropic as your AI service, you will be prompted to enter your API key during the setup process. Be sure to have it ready beforehand.

This is all handled automatically when using the --setup command, so no need for additional configuration commands.

Usage

Once installed, you can use Jarvis-sh by typing jarvis followed by your question or command in the terminal.

Ask a Question

To ask a question:

jarvis Hello

Jarvis-sh will provide an answer directly in the terminal.

If you want to use the ? symbol at the end of your questions to Jarvis, you need to apply the following configuration in your terminal.

Commands

With Jarvis, you can use some commands like /c to get the list of commands or /ct to create unit tests.

1. Command List

To do this, use the /cmd command followed by a description of the command you're looking for.

jarvis /cmd to create a project with vue named AndyDevBlog

If you want to edit the list of custom commands, use jarvis --commands to open the file with the custom command list where Jarvis will look for your command.

2. Create Unit Tests

To do this, use the /ct command followed by the relative path of the file for which you want to create a unit test. You should also include the relative path of the folder where you want the unit tests to be created. You can also add the relative path of example files or general context to help Jarvis generate more accurate unit tests.

jarvis /ct for the file ./src/components/HelloWorld.vue in the folder ./tests/unit/components, using as examples the files ./src/components/Header.vue, ./src/components/HeroSection.vue

3. Create Commit Title and Description

Currently, we offer a command called /commit, which generates the title and description of your staged changes in your Git repository using the Conventional Commits format. To use it, simply run the following command:

jarvis /commit

Example response:

Title: feat: update README with new configuration options and services
Description: Enhanced the README.md by adding new sections for AI service configuration, model configuration, and API key setup for OpenAI. Updated prerequisites to clarify the installation requirements for Node.js and Ollama. Improved descriptions for features and included instructions for service options, enhancing overall clarity and usability.
