DESCRIPTION

-----------

re2c is a free and open-source lexer generator for C/C++, Go and Rust.

Its main goal is generating fast lexers: at least as fast as their reasonably

optimized hand-coded counterparts. Instead of using traditional table-driven

approach, re2c encodes the generated finite state automata directly in the form

of conditional jumps and comparisons. The resulting programs are faster and

often smaller than their table-driven analogues, and they are much easier to

debug and understand. re2c applies quite a few optimizations in order to speed

up and compress the generated code.

Another distinctive feature is its flexible interface: instead of assuming a

fixed program template, re2c lets the programmer write most of the interface

code and adapt the generated lexer to any particular environment.

DOCUMENTATION

-------------

Official re2c website is [re2c.org](http://re2c.org). It has a lot of examples.
