A simple command-line tool for managing environment configurations.

Installation

Prerequisites

First, ensure you have Rust and Cargo installed:

# Check if Cargo is installed
cargo --version || {
  echo "Installing Rust and Cargo..."
  curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
  source "$HOME/.cargo/env"
}

Installing env-manager

Clone the repository and install locally:

# Clone the repository
git clone https://github.com/ncnthien/env-manager.git
cd env-manager

# Build and install
cargo install --path .

After installation, ensure that ~/.cargo/bin is in your PATH:

echo $PATH | grep -q "$HOME/.cargo/bin" && echo "Cargo bin is in PATH" || echo "Add ~/.cargo/bin to your PATH"

If needed, add to your PATH by adding this line to your shell profile (e.g., ~/.bashrc, ~/.zshrc):

export PATH="$HOME/.cargo/bin:$PATH"

Then reload your shell configuration:

source ~/.bashrc  # or ~/.zshrc

Usage

Switch Environment

Switch between different environment configurations:

env-manager switch <environment>

Supported environments:

• dev
• uat
• sit

This command copies the content of .env.<environment> to .env.

Token Management

Add or update the CODE_GEN_TOKEN in your current .env file:

env-manager token <token-value>

This command will:

• Read your current .env file
• Set or replace the CODE_GEN_TOKEN value with the provided token
• Save the changes back to the .env file Display token information:

Examples

# Switch to development environment
env-manager switch dev

# Switch to UAT environment
env-manager switch uat

# Add or update a token in the current .env file
env-manager token your-secret-token

Note

Make sure that you have the corresponding .env.<environment> files in your directory before switching environments.
