Ragel State Machine Compiler
Ragel compiles finite state machines from regular languages into runnable C code. It allows you to embed function calls at any point in your regular language, and to control the non-determinism in the resulting machines. It function calls at any point in your regular language, and to control the non-determinism in the resulting
It understands concatenation, union (the "or" operator), kleene star, subtraction, and intersection, as well as some helpers like "!", "?" and "+". Ragel's finite state machines are closed under all of its operators. This property allows for arbitrary regular lanuages to be described. It can be used to create a parser for any language that is regular.
