The function previously took a size_t* out-parameter for the string length. Since the JSON blob is now null-terminated, the len parameter is unnecessary. Remove it from the Zig implementation, C header, and the WASM example consumer which no longer needs to allocate and free a usize just to read the length.
WebAssembly VT Terminal Example
This example demonstrates how to use the Ghostty VT library from WebAssembly to initialize a terminal, write VT-encoded data to it, and format the terminal contents as plain text.
Building
First, build the WebAssembly module:
zig build -Demit-lib-vt -Dtarget=wasm32-freestanding -Doptimize=ReleaseSmall
This will create zig-out/bin/ghostty-vt.wasm.
Running
Important: You must serve this via HTTP, not open it as a file directly.
Browsers block loading WASM files from file:// URLs.
From the root of the ghostty repository, serve with a local HTTP server:
# Using Python (recommended)
python3 -m http.server 8000
# Or using Node.js
npx serve .
# Or using PHP
php -S localhost:8000
Then open your browser to:
http://localhost:8000/example/wasm-vt/
