About

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

It supports procedural, object-oriented, functional, data-driven, reactive, organizational programming and data description.

Being an extension language, Lua has no notion of a "main" program: it works as a library embedded in a host. The host program can invoke functions to execute a piece of Lua code, can write and read Lua variables, and call Erlang functions by Lua code.

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.

Luerl is a library, written in clean Erlang/OTP. For more information, click on the get started tutorial. You may also browse the examples and learn from the source code.

Luerl goal

A proper implementation of the Lua language

• It SHOULD look and behave the same as Lua
• It SHOULD include the Lua standard libraries
• It MUST interface well with Erlang/OTP

The result

Luerl is a native Erlang implementation of standard Lua 5.3 written for the BEAM ecosystem.

• Easy for Erlang to call
• Easy for Lua to call Erlang
• Erlang concurrency model and error handling

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