create_from_glsl()

bool MayaFlux::Core::VKShaderModule::create_from_glsl	(	vk::Device	device,
		const std::string &	glsl_source,
		vk::ShaderStageFlagBits	stage,
		const std::string &	entry_point = "main",
		bool	enable_reflection = true,
		const std::vector< std::string > &	include_directories = {},
		const std::unordered_map< std::string, std::string > &	defines = {}
	)

Create shader module from GLSL source string.

Parameters

device	Logical device
glsl_source	GLSL source code
stage	Shader stage (determines compiler mode)
entry_point	Entry point function name
enable_reflection	Extract metadata
include_directories	Paths for #include resolution
defines	Preprocessor definitions (e.g., {"DEBUG", "MAX_LIGHTS=4"})

Returns

true if creation succeeded

Compiles GLSL → SPIR-V using shaderc, then calls create_from_spirv(). Requires shaderc library to be available.
