Ragel is a finite-state machine compiler and a parser generator. Initially Ragel supported output for C, C++ and Assembly source code,[4] later expanded to support several other languages including Objective-C, D, Go, Ruby, and Java.[5] Additional language support is also in development.[6] It supports the generation of table or control flow driven state machines from regular expressions[7] and/or state charts and can also build lexical analysers via the longest-match method. Ragel specifically targets text parsing and input validation.[8]
