Case-sensitve options

[mitsuhiko]

The options are case sensitive, the default name that is created for the keyword argument is lowercase. You can explicitly make it uppercase if you want.

Hi, @mitsuhiko
For example:

import click

@click.command()
@click.option("--Hello")
@click.option("--hello")
def hello(**kwargs):
    print(kwargs)

if __name__ == "__main__":
    hello()

I can only get one variable, 'hello'. Any idea for this special case?

Any updates? I really case-sensitive variables corresponding to option names.

[mitsuhiko]

You can do this:

import click

@click.command()
@click.option('hello_1', "--Hello")
@click.option('hello_2', "--hello")
def hello(**kwargs):
    print(kwargs)

if __name__ == "__main__":
    hello()

That said, if you have long options (not short ones) that change in nothing but the capitalization you should probably change the interface to not be confusing for users.
