Ragel compiles finite state machines from regular languages into C, C++, Objective-C, D, Ruby or Java code. Ragel allows the programmer to embed actions at any point in a regular language. Non-determinism can be controlled through the use of embedded priorities and guarded regular language operators. Ragel also supports the construction of scanners and the building of state machines using state-charts. Ragel can be used to create robust recognizers and parsers which run very fast. It can work with integer-sized alphabets and can compile large state machines. The generated code has no dependencies.
