Main entry point and command-line argument processing for the nodeenv tool. Provides comprehensive argument parsing, configuration loading, and orchestration of environment creation operations.

Capabilities

Main Entry Point

Primary entry point for the nodeenv command-line tool that handles argument parsing, configuration loading, and orchestrates the entire environment creation process.

def main():
    """
    Entry point for nodeenv command-line tool.
    
    Processes command-line arguments, loads configuration, and creates
    Node.js virtual environments based on provided options.
    
    Handles special cases like --dump-config-defaults and manages
    global settings for SSL certificates and mirror URLs.
    """

Usage examples:

import nodeenv
import sys

# Create environment with specific Node.js version
sys.argv = ['nodeenv', '--node=16.20.0', 'myenv']
nodeenv.main()

# Create environment with npm and custom jobs
sys.argv = ['nodeenv', '--with-npm', '--jobs=4', 'myenv']
nodeenv.main()

# List available Node.js versions
sys.argv = ['nodeenv', '--list']
nodeenv.main()
