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. Ox handles the tedious and error-prone details of writing code...
A lexical analyzer generator that makes the class source code.
ULS is a class library for creating lexical analyzer from language specification file. It's provided as C/C++/C# and Java (class) libraries with a few of tools on Linux/Windows platform.
Generic Lexer which along with a language definition (.slx) file, constitutes Yacc/Bison compatible, custom lexical parser. It is ~1/3 the size of an equivalent Flex Lexer, resulting in a smaller compiler, and simpler yet more powerful lexical definition.
