yum-slop/modular_slang

modular slang

the idea here is just to make something like slangc.exe, but which treats entrypoints like regular functions.

basics and gotchas

• all functions marked public are exported as entrypoints.
• we use a custom build of slang which lets entrypoints use regular arguments instead of cbuffers / structs.
• it is intended for use with simple math kernels
  • see example.slang for an example. you'd #include example.hlsl in the rest of some shader and call the public APIs.

usage

• import unitypackage
• right click .slang file, select 'Translate to HLSL'
  • it should also auto recompile whenever you tab back into unity
• import the generated .hlsl in your shader

build instructions

git clone https://github.com/yum-food/slang
cd slang
git submodule update --init --recursive -j 32
# wait, the previous command takes a while
mkdir build
cd build
cmake.exe ..
cmake.exe --build . -j 32 --config Release
# the previous command will take a long fucking time
cd ../..
# if in powershell, do this:
powershell.exe ./build.ps1 && ./dist/modular_slang.exe ./demo.slang
# if in bash, do this:
./build.sh && ./dist/modular_slang.exe ./demo.slang
