Class CodeRay::CaseIgnoringWordList
In: lib/coderay/helpers/word_list.rb
Parent: WordList

A CaseIgnoringWordList is like a WordList, only that keys are compared case-insensitively.

Ignoring the text case is realized by sending the downcase message to all keys.

Caching usually makes a CaseIgnoringWordList faster, but it has to be activated explicitely.

Public Class methods
