Feather is a universal UI library that applies user inputs to application state, and maps application state to an interactive visualization using a custom graphics rendering language capable of compiling to arbitrary GPU code or vectorized CPU code.
This project is currently in a prototyping stage, it is not yet suitable for production, and not all planned features are implemented.
Feather is a standard rust project, simply run cargo build on your platform of choice. A NixOS flake is included that provides a develop environment for nix developers who do not have rust installed system-wide.
Two working examples are available: basic-rs and paragraph-rs. To run either, navigate into the folder and run cargo run.
If you are on NixOS, use nix run github:Fundament-Software/feathergui#basic-rs or nix run github:Fundament-Software/feathergui#paragraph-rs
If you are not on nixos but have nix, use nix run --impure github:nix-community/nixGL -- nix run github:fundament-software/feathergui#basic-rs
If you do not have nix, you must navigate into the relevant example folder and run cargo run
The examples have currently only been tested on NixOS and Windows 11, but should work on most systems.
