Kakashi-CLI

A smart environment manager for switching between different .env configurations.

About

Kakashi is a lightweight CLI tool written in Rust that helps you manage multiple environment files (.env.*). Instead of manually editing .env files or juggling multiple configuration files, Kakashi lets you switch between pre-configured environments with a single command.

Perfect for managing different configurations for development, staging, and production environments, or for swapping between different sets of API keys and credentials.

Installation

Clone the repository and install using Cargo:

cargo install --path .

This will compile and install the kakashi binary to your system.

Usage

Initialize

Set up Kakashi in your project:

kakashi init <path>

This creates a .kakashi directory to store configuration and metadata.

List Environments

View all available environment files:

kakashi list

This displays all .env.* files in your current directory.

Switch Environment

Switch to a specific environment:

kakashi switch <env>

This replaces your current .env file with the contents of .env.<env>. For example:

kakashi switch dev     # Loads .env.dev into .env
kakashi switch prod    # Loads .env.prod into .env

Current Environment

Check which environment is currently active:

kakashi current

Example Workflow

# Initialize Kakashi in your project
kakashi init .

# Create your environment files
echo "DB_HOST=localhost" > .env.dev
echo "API_KEY=dev_key_123" >> .env.dev

echo "DB_HOST=prod.example.com" > .env.prod
echo "API_KEY=prod_key_abc" >> .env.prod

# List available environments
kakashi list
# Output:
# dev
# prod

# Switch to development
kakashi switch dev

# Switch to production
kakashi switch prod

# Check current environment
kakashi current
