LanguageDefinition class final

A language described as a set of named lexer states.

Every state is an ordered list of LexRules; the first rule that matches at the current position wins. The state named root is the initial state. Multi-line constructs (block comments, triple-quoted strings) are modelled by rules that switch to another state and back.
