Version 0.1.2 breaks in Ruby 1.8

[geoffgarside]

Version 1.8 doesn't support Symbol#empty? as 1.8 doesn't support :"" as a symbol name.

NoMethodError: undefined method `empty?' for :pending:Symbol
from ..snipped../bundle/ruby/1.8/gems/transitions-0.1.2/lib/transitions.rb:82:in `current_state'

I suppose the easiest fix would be including some code like

begin
  :symbol.empty?
rescue NoMethodError
  class Symbol
    def empty?
      to_s.empty?
    end
  end
end

alternatively if you were to only include the code for Ruby 1.8 then this would suffice as an empty symbol is not possible in 1.8

class Symbol
  def empty?
    false
  end
end

Thanks for this report, however I am highly reluctant to monkeypatch one of ruby's core classes..:)

As far as I can see this commit should fix it: 0be93ff

Let me know it this works for and if yes, I'm gonna release a new gem version.

Thats understandable, I don't usually, but as most gems are gearing towards 1.9 as the default its sometimes more desirable to have a file of backport fixes for the bits you need.

Yep, your commit tests fine for me in 1.8 and 1.9 thank you kindly :)

Alright, 1.0.3 is released..:)
