#### Generators suitable for resource-constrained embedded systems (low-end microcontrollers with few Kb of RAM)

- [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.
