Lua (/ ˈ l uː ə / LOO-ə; from Portuguese: lua meaning moon) is a lightweight, high-level, multi-paradigm programming language designed primarily for embedded use in applications. Lua is cross-platform , since the interpreter of compiled bytecode is written in ANSI C , [4] and Lua has a relatively simple C API to embed it into applications. Luvit and Diaverum has worked in partnership for several years to develop a learning environment that supports learners to effectively complete the Competence in Practice progamme.

In most cases, you just want to install lit as quickly as possible, possibly in a Makefile or make.bat in your own library or app. We maintain several binary releases of luvi to ease bootstrapping of lit and Get Lit and Luvit. If you’re on Linux, FreeBSD, or OSX, run the following script to download luvi and build lit and luvit for your platform: curl -L https: / /github .com /luvit /lit /raw /master /get-lit .sh | sh. If you’re on windows, run the sister command in your cmd.exe command prompt (requires Powershell >= 3.0).
