Python Virtual Environments

Snippet to automatically activate an existing virtual environment or initialize and activate a new one.

Usage: add to your .zshrc, source it, then just run pyvenv.

pyvenv() {
    # Check if .venv directory already exists
    if [ -d ".venv" ]; then
        echo "Found existing environment. Activating..."
    else
        echo "Creating new virtual environment..."
        python3 -m venv .venv
        
        # Automatically add .venv to .gitignore if it's not already there
        if [ -f ".gitignore" ]; then
            if ! grep -qs "^.venv/" .gitignore; then
                echo ".venv/" >> .gitignore
                echo "Added .venv/ to .gitignore."
            fi
        fi
    fi

    # Activate and confirm
    source .venv/bin/activate && \
    echo "Virtual environment at $(pwd)/.venv activated!"
}
