1 1.1 mrg glcpp -- GLSL "C" preprocessor 2 1.1 mrg 3 1.1 mrg This is a simple preprocessor designed to provide the preprocessing 4 1.1 mrg needs of the GLSL language. The requirements for this preprocessor are 5 1.1 mrg specified in the GLSL 1.30 specification availble from: 6 1.1 mrg 7 1.1 mrg http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.30.10.pdf 8 1.1 mrg 9 1.1 mrg This specification is not precise on some semantics, (for example, 10 1.1 mrg #define and #if), defining these merely "as is standard for C++ 11 1.1 mrg preprocessors". To fill in these details, I've been using a draft of 12 1.1 mrg the C99 standard as available from: 13 1.1 mrg 14 1.1 mrg http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf 15 1.1 mrg 16 1.1 mrg Any downstream compiler accepting output from glcpp should be prepared 17 1.1 mrg to encounter and deal with the following preprocessor macros: 18 1.1 mrg 19 1.1 mrg #line 20 1.1 mrg #pragma 21 1.1 mrg #extension 22 1.1 mrg 23 1.1 mrg All other macros will be handled according to the GLSL specification 24 1.1 mrg and will not appear in the output. 25 1.1 mrg 26 1.1 mrg Known limitations 27 1.1 mrg ----------------- 28 1.1 mrg A file that ends with a function-like macro name as the last 29 1.1 mrg non-whitespace token will result in a parse error, (where it should be 30 1.1 mrg passed through as is).
