Tired of editing Vulkan/OpenGL shaders in string form?
Me too! Make an .hlsl or .glsl file and use whatever text editor you like instead.
(Bonus: VS will do syntax highlighting on .hlsl files)

Once you move your shaders to their own files you can use this to convert them to strings:

// Load a shader file as a string of characters.
std::string ShaderAsString(const char* shaderFilePath) {
	std::string output;
	unsigned int stringLength = 0;
	GW::SYSTEM::GFile file; file.Create();
	file.GetFileSize(shaderFilePath, stringLength);
	if (stringLength && +file.OpenBinaryRead(shaderFilePath)) {
		output.resize(stringLength);
		file.Read(&output[0], stringLength);
	}
	return output;
}

Then just nab the string and send it to the relevant shader compiler in your code.
Unless you are using something like "shaderEd" You will still need to check them for compile errors at run-time.
However, this should make editing them between compiles way less annoying.
