Get arguments/options of sub-generator

[SamVerschueren]

Hi, I'm not sure if this is possible, so if not, just tell me and close the issue :).

So in a sub-generator, it's possible to define arguments and options as described in the section Arguments (and Options). Is it possible to retrieve those together with the generators metadata?

The reason I'm asking this is because I'm writing a VS Code plugin and I support sub-generators. But some sub-generators have arguments, which I'm not aware off. As you can see in this block off code, I'm running the sub-generator, if it throws an error with a specific message, I show an input box where the user can pass in it's argument. This feels very hacky and I was hoping for a better way.

The same goes for the options. If I could retrieve the options of a sub-generator, I can show a multi-select list where the user can pick the options he wants.

Any thoughts on this?

I don't think we have it explicitly exposed. You can call .help() to get the help message.

We should totally fix this.
