Uiua is a tacit, stack-based array programming language implemented in Rust, inspired by APL. It ships as a local interpreter/REPL with a built-in language server for editor integration, plus an online interpreter at uiua.org.

Use cases

• write tacit array programs
• learn array programming like APL
• run a REPL for an array language
• experiment with stack-based point-free code
• integrate an array language into an editor via LSP
• do concise data/array manipulation

When to choose

• you want a modern APL-like array language with active development
• you prefer tacit/point-free programming style
• you need a cross-platform interpreter with editor tooling

When to avoid

• you need a mainstream production language with large ecosystems
• you dislike stack-based or symbol-heavy syntax
• you need long-term stability guarantees for critical systems
