Is there anyway to display help from within an action?

[pietschy]

Howdy,

I've got an app with a number of commands and I'd like to display the help if the global action is run. Is there an easy way to do that?

Thanks

Looking into a bit the method to invoke seems to be Trollop::Parser#educate but it looks like it might be tricky to invoke it. For a quick hack I'm just calling:

    app.action do |options, arguments|
      puts `#{__FILE__} --help`
    end

Hmm, there is no easy way right now, I like your hack though, very clever.

An old colleague would have described it as brute force and ignorance so I'm happy to go with clever (c:

@skorks I too would love to provide --help by default, please consider the is a feature request ;)
