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, you will need to install it via Cargo. This requires Rust to be installed.
You can install with:
cargo install uiua
To enable audio output, enable the audio feature:
cargo install uiua --features audio
If you want audio on Linux, you may need to install some dependencies first:
apt install libasound2-dev libudev-dev pkg-config
The interpreter has a built-in language server that implements the Language Server Protocol.
A language client extension is available for VSCode here.
The language client requires that the interpreter is installed locally and available on your PATH.
You can configure Uiua's formatter by creating a file called .fmt.ua in the directory from which you run the interpreter. This configuration file is also a Uiua program.
Configuration options are specified by binding values to specific names.
Example with default values:
TrailingNewline ← 1
CommentSpaceAfterHash ← 1
MultilineIndent ← 2
CompactMultilineMode ← "auto"
The following configuration options are available:
Type: boolean
Default: 1

Type: natural number
Default: 2
The number of spaces to indent each line of a multiline expression.
Type: one of "always", "never", or "auto"
Default: "auto"
How to format multiline expressions.
"always": Always format multiline expressions in compact mode."never": Never format multiline expressions in compact mode."auto": Format multiline expressions in compact mode if they do not exceedMultilineCompactThreshold.
Type: natural number
Default: 10
The maximum number of lines a multiline expression can have before it is formatted in compact mode.
Only used if CompactMultilineMode is not "never".
