Uiua (pronounced "wee-wuh") is a stack-based array programming language.
Documentation, examples, and an online interpreter can be found at uiua.org.
You can also check out the Discord server.
You can support Uiua's development via GitHub Sponsors.
You can try the language without installing anything on the website.
If you want to install the interpreter locally there are 2 options:
-
If your OS is supported, you can simply download the latest release.
-
If not, you will need to install via Cargo. This requires Rust (>=1.75) to be installed.
You can install with one of the following commands:
cargo install uiua -F full # Installs all features cargo install uiua # No audio, webcam, or window features
On Linux, you may need to install some dependencies first:
apt install libx11-dev libffi-dev
The following optional features are available but not enabled by default (enabled by passing
--features <feature>
):full
: Enables all optional features belowaudio
: Enables audio system functions (may requirelibasound2-dev libudev-dev pkg-config
on Linux)webcam
: Enables webcam system functions (may requirelibjpeg-dev
on Linux)window
: Enables output in a window

If you use Nix or NixOS, you can clone this repo and do following:
nix develop # to drop into a shell prompt with all the dependencies cargo check # to make sure you can compile/build latest version cargo build # to build latest debug version of uiua cargo run repl # to get uiua repl
nix develop
is not necessary if you have direnv active, in that casedirenv allow
will activate the flake devshell.Note: If you encounter errors such as rustc or any other package version mismatch, it is most likely that flake.lock file needs to be updated to pull in updated dependencies for nix shell.
The Uiua native interpreter has a built-in language server that can be used by editor extensions.
You can find a list of editor extensions here.
You can find a list of fonts that support Uiua's characters here.
