Urn Travis Build Status Build status

Urn is a new language developed by SquidDev, and demhydraz. Urn is a Lisp dialect with a focus on minimalism which compiles to Lua.

What?

  • A minimal Lisp implementation, with full support for compile time code execution and macros.
  • Support for Lua 5.1, 5.2 and 5.3. Should also work with LuaJIT.
  • Lisp-1 scoping rules (functions and data share the same namespace).
  • Influenced by a whole range of Lisp implementations, including Common Lisp and Clojure.
  • Produces standalone, optimised Lua files: no dependencies on a standard library.

Features

Various looping constructs

Powerful assertion and testing framework

First-class support for Lua tables
