Brailk — VWC naar LaTeX Converter

Convert VWC (Vlaamse Wiskundecode) to KaTeX-compatible LaTeX. Entirely client-side — runs in the browser via WebAssembly.

Stack

• WASM — Converter compiled from Rust via wasm32-unknown-unknown (68KB, zero imports)
• JS — Thin bridge (allocate WASM memory, call converter, parse JSON result)
• KaTeX — Client-side LaTeX rendering
• HTML/CSS — UI

No backend, no Python, no Pyodide. Open index.html directly from the filesystem.

Usage

Open index.html in a browser. Type VWC code in the left panel, click "Omzetten". LaTeX renders on the right.

VWC examples

VWC	LaTeX
x + y = 3	x + y \approx 3
$br x+1/x-1#	\frac{x+1}{x-1}
$wt x+1#	\sqrt{x+1}
μa	\alpha
sin(x)	\sin(x)
x^2#	x^{2}
$R	\mathbb{R}

Development

The converter is written in Rust in src/lib.rs. Build:

cargo build --target wasm32-unknown-unknown --release
cp target/wasm32-unknown-unknown/release/vwc_converter.wasm static/

Run tests:

cargo test
