Allow showing options of a command before typed

[cool-RR]

Hi,

I opened this issue: click-contrib/click-repl#11 for a separate project (click-repl) that uses python-prompt-toolkit. Here's my issue there:

My motivation for using `click-repl` is to make my script more discovereable for users. So it'll be nice if, when they're starting to type a command, the options for that command would show on the screen so they could choose from them, even without typing `-`.

As you can see from @untitaker 's response, he doesn't know how to make python-prompt-toolkit provide that.

Can python-prompt-toolkit provide that? Is this a feature request?

I have not done much research, I don't think opening issues for support is appropriate.

That should be possible. And it is also fine to create an issue, even for questions. (We don't have a mailing list.)
But I will try to have a look at the click-repl code later this week. I guess it can be done by changing the Completer class that click-repl passes to prompt_toolkit, but I'm not yet sure right now.

Thanks Jonathan!
