This isn't ideal for two reasons: 1. There's a bunch of stateful redundancy in the lexer that should be cleaned up. 2. The hash table does not provide a mechanism to delete an entry, so we waste memory to add a new NULL entry in front of the existing entry with the same key. But this does at least work, (it passes the recently added undef test case).
glcpp -- GLSL "C" preprocessor This is a simple preprocessor designed to provide the preprocessing needs of the GLSL language. The requirements for this preprocessor are specified in the GLSL 1.30 specification availble from: http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.30.08.pdf This specification is not precise on some semantics, (for example, #define and #if), defining these merely "as is standard for C++ preprocessors". To fill in these details, I've been using the C99 standard (for which I had a convenient copy) as available from: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1124.pdf
