spnda / shader_processor

C++20/CMake library that automatically compiles & packages shaders at compile-time

shader_processor

A CMake library that automatically compiles and packages your shaders into binary files. Using JSON, you can define how your shaders will be packaged and optionally compiled using glslang, slangc, spirv-cross, and Metal.

The library is written in C++20 and currently depends on magic_enum and simdjson.

Usage

In your CMakeLists.txt, you need to call some functions of the library.

add_executable(my_game "game.cpp")

# This will now search for JSONs in the "shaders" directory, generate targets for them, and add them
# as a dependency of the "my_game" target.
create_shader_targets(shaders my_game)

Everytime you modify one of the JSONs or the shaders they will automatically be rebuilt and packaged when building the project.

Supported compilers

• glslang
• slangc

Support for HLSL, Metal, and SPIRV-Cross will be added in the future.

TODOs

• Configurable output directory
• Shader compression (LZMA?)
• Support for multiple output directories and targets
• Better stage resolution. (Input GLSL and target MSL should create a chain of GLSL -> SPIR-V -> MSL)
