Contents of README: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.1.30.10.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 a draft of the C99 standard as available from: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf Any downstream compiler accepting output from glcpp should be prepared to encounter and deal with the following preprocessor macros: #line #pragma #extension All other macros will be handled according to the GLSL specification and will not appear in the output. Known limitations ----------------- 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). |
