+-   [ragel](http://www.colm.net/open-source/ragel/) (embedded C, C++, Java, Go, Ruby, C#):
+    Ragel compiles executable finite state machines from regular languages. 
+    Ragel state machines can not only recognize byte sequences as regular 
+    expression machines do, but can also *execute code at arbitrary points
+    while the recognition process goes*. The key feature is a very compact
+    and human-readable *embedded C* code does not consume any buffers
+    and don't use external libraries. Has *FSM plotting for code documentation*.
+-   [re2c](http://re2c.org) (embedded C):
+    re2c is a free and open-source lexer generator for C and C++.
+    Its main goal is generating fast and compact embeddable lexers.
+    Instead of using traditional table-driven approach, re2c encodes the
+    generated finite state automata directly in the form of conditional
+    jumps and comparisons. Generated code does not use OS/libc buffering and I/O.
