Lua ( LOO-ə, from Portuguese: lua [ˈlu.(w)ɐ] meaning moon) is a lightweight, multi-paradigm programming language designed primarily for embedded systems and clients. Lua is cross-platform, since the interpreter is written in ANSI C, and has a relatively simple C API. Lua was originally designed in 1993 as a language for extending software applications to meet the increasing demand for customization at the time. Read more on Wikipedia...

Example from Riju:
print("Hello, world!")
Example from hello-world:
print("Hello World")
# Hello World in Lua print "Hello world"
Example from Linguist:
-- A simple counting object that increments an internal counter whenever it receives a bang at its first inlet, or changes to whatever number it receives at its second inlet. local HelloCounter = pd.Class:new():register("h-counter") function HelloCounter:initialize(sel, atoms) self.inlets = 2 self.outlets = 1 self.num = 0 return true end function HelloCounter:in_1_bang() self:outlet(1, "float", {self.num}) self.num = self.num + 1 end function HelloCounter:in_2_float(f) self.num = f end
Example from Wikipedia:
$ cc -o example example.c -llua $ ./example Result: 8
and break do else elseif end false for function if in local nil not or repeat return then true until while
