Luerl is an implementation of standard Lua 5.3 written in Erlang/OTP. Lua is a powerful, efficient, lightweight, embeddable scripting language common in games, IoT devices, machine learning and scientific computing research.

The Luerl VM is a mixture of interpreting Lua VM instructions and using Erlang directly to implement function calls.

Through the use of Erlang functions, Luerl can be augmented to cope with a wide range of different domains, creating a customized language sharing a syntactical framework.
