"""String tools example Fire CLI.

This module demonstrates the use of Fire without specifying a target component.
By calling Fire() without arguments in main(), all functions defined in this
module become available as CLI commands.

Example usage:
  string_tools reverse "Hello World"
  string_tools uppercase "hello"
  string_tools count-words "Hello world from Fire"
"""

import fire


def reverse(text=''):
  """Return the reversed string."""
  return text[::-1]


def uppercase(text=''):
  """Return the text in uppercase."""
  return text.upper()


def count_words(text=''):
  """Return the number of words in the text."""
  return len(text.split())


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


if __name__ == '__main__':
