Setup & Configuration

To use DiffCraft, you need a Google Gemini API key.

Method 1: .env File (Recommended)

This method is easy and keeps your API key specific to your project.

1. Get your free API key from Google AI Studio.

2. In the root directory of your git project, create a new file named .env.

3. Add the following line to the .env file, pasting your own key:

GEMINI_API_KEY="YOUR_API_KEY_HERE"

🔒 Important Security Note Remember to add the .env file to your project's .gitignore to ensure your secret API key is never committed to your repository! If your .gitignore doesn't have it, add this line:

.env

Method 2: Environment Variable (Advanced)

This method is ideal for servers, CI/CD pipelines, Docker containers, or any user who prefers to manage API keys globally. DiffCraft will always prioritize a system-wide environment variable over a local .env file. Open your terminal and use the appropriate command for your operating system.

macOS / Linux

export GEMINI_API_KEY="YOUR_API_KEY_HERE"

To make this permanent, add the command to your ~/.zshrc or ~/.bashrc file.

Windows (PowerShell)

$env:GEMINI_API_KEY="YOUR_API_KEY_HERE"

Windows (CMD)

set GEMINI_API_KEY="YOUR_API_KEY_HERE"

For permanent setup on Windows, search for "Edit the system environment variables" in the Start Menu. You will need to close and reopen your terminal for the changes to take effect.

Usage

The workflow is designed to be seamless.

1. Stage your files as you normally would:

git add .

2. Run the craft command:

craft

This will generate a commit message and present you with the interactive prompt.

Or,

craft .

This will both stage the files and generate a commit message.
