Ox is an attribute grammar compiling system that augments Lex and Yacc specifications with definitions of synthesized and inherited attributes written in a combination of Ox and C/C++ syntax. From these augmented specifications, Ox generates ordinary Lex and Yacc specifications that build and decorate attributed parse trees.
The user can specify parse-tree traversals for easy ordering of side effects such as code generation.
jsBison is a parser generator which can read bison style grammar definitions and generates according parsers written solely in javascript. Therefore, using jsBison it is easily possible to perform "real" parsing on websites on the client side.
