LUA Environment and Setup

LUA  Environment and Setup

1. Install the environment on MAC
>wget http://www.lua.org/ftp/lua-5.2.3.tar.gz
>tar zxf lua-5.2.3.tar.gz
>cd lua-5.2.3
>make macosx test

>sudo make macosx install

Lua 5.2.3  Copyright (C) 1994-2013 Lua.org, PUC-Rio

First Hello World
>vi hello.lua
print("hello")

>lua hello.lua
hello

Just use Intellij and install the plugin
[Preferences] ——> [Plugins] ———> [Browse Repositories] ———> Search for ‘lua for’ and I will get Lua language integration for IntelliJ

Then I can edit the Lua script in my intelliJ and run them using my command line.

If I want to run the script inside IntelliJ, I will click on the ‘edit configuration’ and  change the ‘Lua interperter’ and ‘Working directory’ there.

Lua interperter —> /usr/local/bin/lua
Working directory —> /Users/carl/work/easy/easylua/src/main/lua

Go over my old blog and tried some examples there. All the examples are in the project easylua.

function fact(n)
    if n== 0 then
        return 1
    else
        return n*fact(n-1)
    end
end

print("enter a number:")
a = io.read("*number")
print(fact(a))
