Previously '=' was not included in our PUNCTUATION regeular expression, but it *was* excldued from our OTHER regular expression, so we were getting the default (and hamful) lex action of just printing it. The test we add here is named "punctuator" with the idea that we can extend it as needed for other punctuator testing.
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 Known limitations ----------------- Macro invocations cannot include embedded newlines. The __LINE__, __FILE__, and __VERSION__ macros are not yet supported. The argument of the 'defined' operator cannot yet include enclosing parentheses. The #error, #pragma, #extension, #version, and #line macros are not yet supported. A file that ends with a function-like macro name as the last non-whitespace token will result in a parse error, (where it should be passed through as is).
