What is ocaml-lua

OCaml-lua provides bindings to the Lua programming language. Lua is a scripting language particularly useful when you need to embed a language in your application.

This project provides the bindings required to embed Lua.

More information about Lua

Introduction

Lua is a powerful, light-weight programming language designed for extending applications. It provides a good general purpose programming language to replace DSL that don't really need to be specific.

This library provides bindings to Lua API which allows the application to exchange data with Lua programs and also to extend Lua with OCaml functions.

This is the OCaml complete binding of the Lua Application Program Interface as described in the official documentation.

In this moment only the version 5.1.x is supported.

Intended audience

This library is intended to be useful to OCaml developers needing a dynamic language to be included in their projects, for configuration or customization purposes. Instead of reinventing yet another DSL, one should consider using an existing programming language and Lua is in my opinion the perfect companion of a statically typed language like OCaml.

In a few lines of code you can create a Lua interpreter and run a Lua program inside it. You can provide the Lua state with library functions written in OCaml and available to the Lua program.

More informations about Lua can be found on the documentation page.

My advice is to read the book "Programming in Lua", written by the author of the language, Roberto Ierusalimschy.

To compile:

1. cd src/lua_c ; tar xf lua-5.1.5.tar.gz
2. cd lua-5.1.5 ; patch -p1 -i ../lua.patch
3. cd .. ; mv lua-5.1.5 lua515
4. cd ../.. ; dune build @install
5. dune build @doc
