Get the name of the currently executing method in Ruby

Question

So $0 is the env variable for the top level Ruby program ... but is there one for the current method?

Answer 1

From http://snippets.dzone.com/posts/show/2785:

module Kernel
private
    def this_method_name
      caller[0] =~ /`([^']*)'/ and $1
    end
end

class Foo
  def test_method
    this_method_name
  end
end

puts Foo.new.test_method    # => test_method

Answer 2

Even better than my first answer you can use __method__:

class Foo
  def test_method
    __method__
  end
end

This includes a : before the name which you can easily remove.

Note: This requires Ruby 1.8.7.
