A library for parsing Unity shaders. Consists of a few distinct components:
- A parser for ShaderLab, Unity's own Shader DSL.
- A parser for HLSL, the shading language embedded in ShaderLab.
- A preprocessor for dealing with macros before parsing.
- A framework for analyzing syntax trees using the visitor pattern, and for making edits to the corresponding source code.
Example usages:
- Used in Slang shading language plugin for Unity, here.
- Used in Orels' Unity shaders, in a few places (example 1, example 2).
- Another small example in this issue.
- The tests contain many small examples.
