ShadowDusk.Slang 0.21.0

ShadowDusk.Slang

Genuine Slang input for MonoGame/KNI: import, generics, interface conformances, everything the real Slang compiler accepts. This package bundles slangc and compiles .slang source with slangc -target hlsl, then hands that HLSL to ShadowDusk's existing, unchanged, faithful DXC pipeline (the same DXC every .fx uses).

using ShadowDusk.Core;
using ShadowDusk.Slang;

var result = await new SlangCompiler().CompileAsync(
    slangSource, new CompilerOptions { Target = PlatformTarget.OpenGL, SourceFileName = "Blur.slang" });
byte[] mgfx = result.Value.Data;

The same route also feeds ShadowDusk's source-text converters, for SkiaSharp and raylib (fragment-only, with the converters' own limits and SD06xx refusals):

var sksl = new SlangCompiler().ConvertToSksl(slangSource, new SkslConvertOptions { SourceName = "Fx.slang" });
var raylib = new SlangCompiler().ConvertToRaylib(slangSource, new RaylibConvertOptions { SourceName = "Fx.slang" });

Nothing to install: slangc rides inside this package for win-x64, linux-x64, osx-x64 and osx-arm64 and resolves from your app's own output, whether you dotnet run or publish self-contained. Two host floors come from the upstream binaries themselves:

• Linux needs a GCC 11+ libstdc++ (Ubuntu 22.04 or later).
• macOS needs macOS 26 or later: the upstream macOS build declares that minimum. ShadowDusk does not build its own slangc for older macOS; open an issue if you need one.

On any other host, SlangCompiler returns SD0620 naming the reason instead of crashing. That includes Windows on Arm (win-arm64): upstream publishes a slangc for it, but it is not bundled, to keep the package small for everyone else. Open an issue at https://github.com/kaltinril/ShadowDusk/issues if you need it. (An x64 process on Windows on Arm is a win-x64 host and works.)

Parameter names are the ones you wrote: cbuffer members, Texture2D/SamplerState globals, and a combined Sampler2D Comb;, whose texture reflects as Comb (effect.Parameters["Comb"].SetValue(texture)). A texture held in a struct global, in a cbuffer/ParameterBlock, or taken as an entry-point uniform parameter has no name you wrote that could identify it and is rejected with SD0640; declare it as a global of its own.

This is a separate, optional package. A consumer who does not add it pays zero size or dependency cost. ShadowDusk.Compiler's own .slang support (an HLSL-compatible subset, no extra package, every host including the browser) is untouched.
