Teal – A statically-typed dialect of Lua

Teal is a statically-typed dialect of Lua that adds type annotations—including arrays, maps, records, interfaces, union types, and generics—while maintaining Lua's minimalism and embeddability, similar to TypeScript's role in JavaScript. The language compiles .tl source files into .lua files via the tl compiler and offers IDE support, documentation, and a browser-based playground for experimentation. Teal is free and open-source software licensed under MIT.
