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.
