wgsl

WGSL syntax highlighter. Pure (text) -> { Segment }. Mirrors the algorithm of the deleted Rust highlight_wgsl (renderer.rs): // line comments, /* ... */ block comments, "..." strings with \ escapes, @attribute tokens, numeric literals (digits + dots + alphanumerics for suffixes like 1u, 0xFF, 1.0_f32), and identifiers dispatched against the WGSL keyword and built-in type tables. Colors flow from ui.getToken("code.<role>") via the active theme; hardcoded fallbacks match the deleted Rust values when no theme is active.

Exports

• highlight(text: string) -> { Segment } — tokenize a WGSL string into colored segments for the zui code renderer. The module returns this function directly.

Types:

• Segment = { text: string, color: string, monospace: boolean }

Usage

local highlight = require("@builtin::modules.zui.highlight.wgsl")
local segments  = highlight("@vertex fn main() -> vec4<f32> {}")

Notes

• Pure function — no side effects, no state. Safe to call any time.
• Keyword and type tables match the deleted Rust constants verbatim (renderer.rs:6245-6263).
• Strings are escape-aware ("a\"b" is one segment); WGSL has no single-quoted strings.
