A bunch of useful click parameter types.

I often find myself wanting to use a click parameter able to handle list of strings, so I decide to put this in a library and I ended adding more parameter types that can be useful for various scripts including network, mathematics and so on.

pip install click-params

click-params starts working from python 3.8. It has a few dependencies:

• click >= 7.0
• validators
• deprecated

import click
from click_params import Ipv4AddressListParamType

@click.command()
@click.option('-a', '--addresses', help='list of ipv4 addresses', prompt='list of ipv4 addresses to reserve',
 type=Ipv4AddressListParamType())
def pool(addresses):
    click.echo('reserved ips:')
    for ip in addresses:
        click.echo(ip)

$ pool --addresses='192.168.1.1,192.168.1.14'
reserved ips:
192.168.1.1
192.168.1.14

You can change the default separator "," by passing it when initializing the parameter type.
