"""URL utilities Fire CLI.

This module demonstrates using Fire to expose URL helper functions.
Fire() is invoked without a target component, so all functions are available
as CLI commands.

Example usage:
  url_tools encode "Hello world!"
  url_tools decode "Hello%20world%21"
  url_tools domain "https://google.com/search?q=fire"
"""

import fire
from urllib.parse import quote, unquote, urlparse


def encode(text=''):
  """URL-encode the given text."""
  return quote(text)


def decode(text=''):
  """URL-decode the given text."""
  return unquote(text)


def domain(url=''):
  """Return the domain name from the given URL."""
  return urlparse(url).netloc


def main():
  fire.Fire(name='url_tools')
