Use HighLine menu system about commander

[ggilder]

There are a couple of workarounds you could use here.

Call the method directly from the class:

HighLine.method(:choose).call do |menu|
  menu.prompt = "Select an option:"
  menu.choice("Do this one") { puts "I did the first one." }
  menu.choice("Do the other one") { puts "I did the second one." }
end

Or alias it:

require 'highline/import'
alias :highline_choose :choose
require 'commander/import'

command :foo do |c|
  c.action do |args, options|
    highline_choose do |menu|
      menu.prompt = "Select an option:  "
      menu.choice("Do this one") { puts "I did the first one." }
      menu.choice("Do the other one") { puts "I did the second one." }
    end
  end
end

It's an unfortunate naming conflict... the only thing I can think of as an acceptable workaround would be for Commander to provide an alias to the original HighLine method, like highline_choose. Otherwise we could break existing code. What do you think?

Actually, I see that our version of choose delegates to HighLine's version, so we can probably improve this. I'll take a stab at it.

Cool. Otherwise I think the alias is reasonable. I'm an experienced programmer, but new to Ruby and all its idioms.

I've released the fix in 4.2.1. Thanks for reporting the problem!
