==========
|
|
|
|
Click is a Python package for creating beautiful command line interfaces
|
|
in a composable way with as little code as necessary. It's the "Command
|
|
Line Interface Creation Kit". It's highly configurable but comes with
|
|
sensible defaults out of the box.
|
|
|
|
It aims to make the process of writing command line tools quick and fun
|
|
while also preventing any frustration caused by the inability to
|
|
implement an intended CLI API.
|
|
|
|
Click in three points:
|
|
|
|
- Arbitrary nesting of commands
|
|
- Automatic help page generation
|
|
- Supports lazy loading of subcommands at runtime
|
|
|

|
@click.option("--count", default=1, help="Number of greetings.")

|
@click.option("--name", prompt="Your name",
|
|
help="The person to greet.")
|
|
def hello(count, name):
|
|
"""Simple program that greets NAME for a total of COUNT times."""
|
|
for _ in range(count):
|
|
click.echo("Hello, %s!" % name)
|
|
|
|
if __name__ == '__main__':
