    Message : Use C++11 raw string literals instead of SHADER_SOURCE macro This is better in many ways: 1. It doesn't confuse clang format 2. \n doesn't need to be included after preprocessor directives like the version directive. 3. It's using built-in functionality instead of something custom. Raw string literals should be the preferred way to include shader source in C++ files going forward.
