How to parse rake arguments with OptionParser

Question

Reffering that answer I was trying to use OptionParser to parse rake arguments. I simplified example from there and I had to add two ARGV.shi

Answer 1

I know this does not strictly answer your question, but did you consider using task arguments?

That would free you having to fiddle with OptionParser and ARGV:

namespace :user do |args|
  desc 'Creates user account with given credentials: rake user:create'
  task :create, [:username] => :environment do |t, args|
    # when called with rake user:create[foo],
    # args is now {username: 'foo'} and you can access it with args[:username]
  end
end
