I'm almost certainly reinventing_the_wheel, and probably doing it
badly, but I don't mind having this hanging around on my system, so
here it is:

  #!/usr/bin/ruby -wp

  BEGIN {
    class String
      def decamel
	gsub!(/\b[^\WA-Z]+[A-Z].*?\b/) do |x|
	  x.gsub!(/[A-Z][^\WA-Z]+/) {|s| "_" + s.downcase }
	  x.gsub!(/[A-Z][A-Z]+/)    {|s| "_" + s }
	  x
	end
      end
    end
  }

  $_.decamel


I'm assuming that class names like this should not be changed:

   class SomeClass

and that in cases like this:

   someDBMMethod

"DBM" should be kept uppercase.

Comments, changes, dismissal, etc. welcome :-)
