tur-glsl

Lisp-syntax DSL that compiles to GLSL shader source. Author vertex and fragment shaders in Turmeric and emit GLSL strings ready to feed to tur-opengl (or any other GL backend).

Overview

tur-glsl is a Tier 1 spice (pure Turmeric, no C deps). It mirrors the shape of tur-c-dsl but targets GLSL: shader stages, uniforms, inputs, outputs, and the standard GLSL built-ins are modeled as Turmeric values and rendered by compile-glsl.

Pair it with tur-opengl for an end-to-end "shader in Turmeric" workflow, or use it stand-alone to bake GLSL strings at build time.
