Ghostling
Ghostling is a demo project meant to highlight a minimum functional terminal built on the libghostty C API in a single C file. The example uses Raylib for windowing and rendering. It is single-threaded (although libghostty-vt supports threading) and uses a 2D graphics renderer instead of a direct GPU renderer like the primary Ghostty GUI. […]

We rewrote our Rust WASM Parser in TypeScript – and it got 3x Faster
We built the openui-lang parser in Rust and compiled it to WASM. The logic was sound: Rust is fast, WASM gives you near-native speed in the browser, and our parser is a reasonably complex multi-stage pipeline. Why wouldn’t you want that in Rust? Turns out we were optimising the wrong thing. The openui-lang parser converts […]
Discontinuation and reinitiation of dual-labeled GLP-1 receptor agonists
