# Blinker
Blinker provides a fast dispatching system that allows any number of
interested parties to subscribe to events, or "signals".

## Example
Signal receivers can subscribe to specific senders or receive signals
sent by any sender.
```pycon
>>> from blinker import signal
>>> started = signal('round-started')
>>> def each(round):
... print(f"Round {round}")
...
>>> started.connect(each)
>>> def round_two(round):
... print("This is round two.")
...
>>> started.connect(round_two, sender=2)
>>> for round in range(1, 4):
... started.send(round)
...
Round 1!
Round 2!
This is round two.
Round 3!
```

==========
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
Installing
----------
Install and update using `pip`_:
.. code-block:: text
$ pip install -U click
.. _pip: https://pip.pypa.io/en/stable/getting-started/
A Simple Example
----------------
.. code-block:: python
import click
@click.command()
@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(f"Hello, {name}!")
if __name__ == '__main__':
hello()
.. code-block:: text
$ python hello.py --count=3
Your name: Click
Hello, Click!
Hello, Click!
Hello, Click!
