What is Teal (programming language)?

This project comes from the desire of a practical Lua dialect for programming-in-the-large. This is inspired by the experiences working on two large Lua applications.

The goal of the language is to be a dialect of Lua as much as TypeScript is a dialect of JavaScript. So yes, it is on the one hand a different language (there are new keywords such as global for example) but on the other hand it is pretty much recognizable as “Lua + typing”.

It aims to integrate to pretty much any Lua environment, since it’s a “transpiler” that generates plain Lua and has no dependencies. The goal is to support at least both the latest PUC-Rio Lua and the latest LuaJIT as output targets.

Minimalism (for some vague definition of minimalism!) is a design goal for both conceptual and practical reasons: conceptually to match the nature of Lua.
