DESCRIPTION ----------- re2c is a free and open-source lexer generator for C, C++ and Go. 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. DOWNLOAD -------- Release tarballs: https://github.com/skvadrik/re2c/releases Source code: ``` $ git clone https://github.com/skvadrik/re2c.git $ git clone https://git.code.sf.net/p/re2c/code-git ``` Github is the main repo, sourceforge is a mirror and can be slightly outdated. CONTRIBUTING ------------ re2c is an Open Source, community-driven project.
