Where can I find an actively developed lint tool for Ruby?

Question

Most of the code I write is in Ruby, and every once in a while, I make some typo which only gets caught after a while. This is irritating when I have my scripts running long

nitpick might be what you're lookng for.

With this code:

class MyString < String
  def awesome
    self.gsub("e", "3").gsub("l", "1").uppercase
  end
end

puts MyString.new("leet").awesome

... it outputs:

$ nitpick misspelling.rb 
*** Nitpick had trouble loading "misspelling.rb":
    NoMethodError undefined method `uppercase' for "133t":MyString
Nothing to report boss! He's clean!
