tl;dr: Rio is a terminal built to run everywhere, as a native desktop applications by Rust/WebGPU or even in the browser powered by WebAssembly/WebGPU.

Rio current development version is 0.0.4.

Basic features are under development for MacOs right now.

* Development and tests are targeting Wayland, probably is not stable on X11 yet.

* Nintendo Switch development is just for fun, the goal is to have the renderer working and the basic features of a terminal.

Note: Emojis are rendered with Noto Emoji.

Rio is built over a custom renderer called Sugarloaf, which is responsible for font and style rendering. Sugarloaf demo:
