CSSP - CSS preprocessor library Build Status

WARNING
this library is abandoned

What's this

This library is CSS preprocessor built on LALR(1) grammar. It uses Flex (The Fast Lexical Analyzer) and Bison (Yacc-compatible Parser Generator) to handle grammar. It is written in C++11.

CSS grammar has few traps, including significant white spaces and multiple rules with ":" character that cannot be easy handled on parser with single lookahead. For this reasons LALR(1) parser is not good choice to handle CSS grammar, Main goal of this library was achieve high parsing speed, this justify parser choice.
