Hi all

What's the fastest way to convert "ThisIsSomeString" to

p "ThisIsSomeString".scan(/[A-Z][a-z]+/).map{|w|w.downcase}.join('_')
p "this_is_some_string".split('_').map{|w|w.capitalize}.join

I believe this is the fastest way, though it may not catch all cases
(numbers and such)

def lowerize(str) # ??
str.gsub(/([a-z])([A-Z])/, '\1_\2').downcase
end


Cheers,
Daniel

If you have Rails installed:

require 'action_pack'
"ThisIsSomeString".underscore
=> "this_is_some_string"
