Another useful OpenGL macro, at least for me, is this one: #define GLSL(str) (char*)"#version 330\n" #str It basically enables you to embed quick snippets of GLSL inside your C code, instead of using concatenated strings. Example: char* fragShader = GLSL( in vec3 uv; out vec4 color; uniform sampler2DArray tex; void main() { // Comments work too color = texture(tex, uv); } ); In Sublime Text you even get code completion and color highlighting, since GLSL and C look so alike. I believe it might work for OpenCL Kernels too. The only downside is that it doesn't add line breaks by itself (hence the "#version 330\n", which requires a line break), so GLSL Compilation errors aren't as useful.
