Use thelive demoto play with Luaif you don't want to install anything on your computer.

To run Lua programs on your computer,you'll need a standalone Lua interpreterand perhaps some additional Lua libraries.Pre-compiled Lua libraries and executables are available atLuaBinaries.Use your favorite text editor to write your Lua programs.Make sure to save your programs as plain text.If you want an IDE, tryZeroBrane Studio.

If you use Windows,tryLuaDist,a multi-platform distribution of the Lua that includes batteries.

If you use Linux or Mac OS X,Lua is either already installed on your system or there is a Lua package for it.Make sure you get the latest release of Lua(currently 5.4.3).

Lua is also quite easy to build from source,as explained below.

Building from source

Lua is very easy to build and install.Just download it andfollow theinstructionsin the package.

Here is a simple terminal session thatdownloads the current release of Lua and builds it in a Linux system:If you don't have curl, try wget.

If you use Windows and want to build Lua from source,there aredetailed instructionsin thewiki.

Embedding

To embed Lua into your C or C++ program,you'll need the Lua headers to compile your program anda Lua library to link with it.If you're getting a ready-made Lua package for your platform,you'll probably need the development package as well.Otherwise, justdownload Lua andadd its source directory to your project.
