Alternative to click types

[Mitmischer]

In click, I could specify the type of an option, like this: 1 with the types specified here: 2 3 .

This is expecially useful for files with the click.File class.
cloup.File does not exist; Also it looks to me as if the whole typing functionality from click was not adopted. Are there alternatives to achieve similar functionality in cloup?

UPDATE(v0.10.0): Click types are now re-exported by Cloup, so you don't need to import Click.

Cloup is meant to be used in tandem with Click, it's not a replacement for Click. You can use Click types as you do with Click:

import click
import cloup

@cloup.command()
@cloup.option('-o', '--out', type=click.File(...))
def f(out):
    ...

More in general, what you can do with Click, you can do with Cloup too, because Cloup commands are Click commands (subclasses) and Cloup parameters are Click parameters.

Note that, even though Cloup has Click as a dependency, you should explicitly add Click to your requirements too because you are gonna use it directly in your code (usually only for types). I'll add this to the installation instructions.

Sounds good, thanks for the quick response!
Yeah, it was a bit unclear to me whether cloup wanted to be a drop-in-replacement for click or not. With the types re-exported, cloup looks like a proper drop-in-replacement (is this correct?)
Out of curiosity, have you considered merging cloup back into click?

[janluke]

There's still stuff from click that cloup doesn't export. See the "installation" section on the docs.

Cloup adds features that click maintainers don't want to add, except better type hints.

Hmm, quite sad that click maintainers don't want to see this added.
