tl is the compiler and type checker for Teal, a statically-typed dialect of Lua that adds type annotations, generics, and records while compiling back to plain Lua. It ships as a dependency-free tl.lua module, a CLI with run/check/gen subcommands, and a browser playground.

Use cases

  • add static types to a Lua codebase
  • type-check Lua projects
  • compile Teal to plain Lua
  • run typed Lua scripts
  • gradually migrate Lua to a typed dialect

When to choose

  • you write Lua and want TypeScript-like static typing
  • you need a zero-dependency type checker embeddable in Lua projects
  • you target Lua 5.1-5.4 or LuaJIT

When to avoid

  • you need a standalone typed language with its own runtime
  • you want runtime type enforcement rather than compile-time checking
  • you need full IDE support outside Lua tooling ecosystems
