Can a verb have a child verb?

I'd like to allow the following scenarios:

$ app verb -t
$ app verb childverb -u
$ app verb otherchildverb -z

Where -u and -z are both specific to the respective child verbs. Is the documentation in the wiki for this still valid, or has it changed in 2.0+?

Hi @sgrassie, thank you again for being there.

Starting from easy things... 2.0+ documentation is condensed in this part of the wiki.

Command Line never supported nested verb (nor previous stable), but it's a very interesting.

We can introduce a property to set the parent verb:

[Verb("verb1")]
class VerbOptions1 { }

[Verb("verbchild1", Parent="verb1")]
class VerbChildOptions1 { }

Than all options classes will be normally passed to ParseArguments<T1 ... Tn> with properly modified InstanceChooser.Choose call.

Given the way verbs are defined now, out of band, this may be difficult to implement.

It may be possible to recursively call choose with the remaining arguments (after excluding the first matched verb) and incorporate @gsscoder's suggestion of a parent parameter.

Ok thanks, I understand. As of now, my alternative is to create more verb commands, instead of nested ones.

Crazy idea, what if the verb name contained a space? Would that be able to fake a hierarchy?

Isn't this the same as #13? maybe close as a duplicate?
