Pythonic Shader Metaprogramming with Metashade
summary
Metashade is a Python-based EDSL that generates HLSL source code from Python (Apache-2.0 on GitHub) and targets pragmatic needs: managing hundreds of shader permutations, enforcing C-like scoping via with-statements and operator overloading, and emitting plain source rather than an IR. A companion glTF demo uses AMD Cauldron and a Python glTF loader to reimplement AMD shaders as a working proof of concept, arguing it avoids C preprocessor limits and differs from Warp/Triton-style transpilers.
