Troy,

You might want to check SimpLex at:


http://sourceforge.net/projects/simplex


It is an ANSI C, open source, bison compatible, generic lexer. It is not a
generator, rather, it is data driven by an #included .slx language
definition file. It has very strong context capabilities by utilizing YACC
like rules for context analysis.


The resulting lexer is typically 1/2 to 1/4 of an equivalent Flex generated
lexer, and is just as fast (or faster).
