  "FooBar::Baz" .underscore  #=> "foo_bar/baz"
"::FooBar::Baz" .underscore  #=> "foo_bar/baz"
  "HTTPRequest" .underscore  #=> "http_request"

Parameters:

• klassname (String) —

  Class name (may include module name).

Returns:

• (String) —

  Underscored name.

	s.gsub!( /::/, '/' )  # replace namespace separator by "/"
	s.gsub!( /([A-Z0-9]+)([A-Z][a-z])/x ,'\\1_\\2' )  # un-camel-case
	s.gsub!( /([a-z0-9] )([A-Z]     )/x ,'\\1_\\2' )  # "
	s.tr!( '-', '_' )  # replace hyphens by underscores
	s.downcase!  # lowercase. who would have thought?
