feat: Added support for hidden inputs

Hidden Input support

Hiding input in TUI when hide_input=True for an option

@click.option("--foo", hide_input=True)
def exec(foo):
     ...

Thanks for this!

Does it make sense to have hide_input on options that don't have prompt? My gut feeling is that hide_input is not something that Trogon should handle at all, since it's Click that will accept the input for it.

I think if the option has prompt=True or hidden=True, then we should just not render any widget for it in the form.

Makes sense how about having something that gives info on hide_input flag for a command even if it isn't rendered then?

I think hide_input doesn't make sense, since hide_input is something Click uses when prompt=True to hide the characters the user types. All of the prompt stuff is handled inside Click.

Based on @darrenburns remarks, it would make the most sense that Trogon presented textboxes for these arguments that redacted user input; a textbox for secrets. Does Textual provide such a widget?

[fresh2dev]

Based on click docs, the proper way to handle these options is self-evident, IMO.

https://click.palletsprojects.com/en/8.1.x/api/#click.Option

hide_input (bool) – If this is True then the input on the prompt will be hidden from the user. This is useful for password input.

hidden (bool) – hide this option from help outputs.

Will the hidden option also be tackled in this pr? My organisation can't wait to use trogon, but is blocked by #29

I have a (hopefully temporary) fork of Trogon to make click an optional dependency.

https://github.com/Textualize/trogon/pull/38

In this fork, I just implemented the ability for Trogon to:

• omit hidden parameters and subcommands (when hidden=True)
• show read-only input for required prompts (when prompt=True, prompt_required=True)
• redact sensitive values (when hide_input=True) <-- This was tricky!
