Syntax

Squirrel uses a C-like syntax

Factorial in Squirrel:

function factorial(x)

else 
}

Random numbers using generators:

function gen_random(max) 
}

local randtor = gen_random(100);


for(local i = 0; i < 10; i += 1)
print(">"+resume randtor+"\n");

Classes and inheritance:

class BaseVector 
}


x = 0;
y = 0;
z = 0;
}


class Vector3 extends BaseVector 
function Print()

}


local v0 = Vector3(1,2,3)
local v1 = Vector3(11,12,13)
local v2 = v0 + v1;
v2.Print();

History

The language was made public in 2003 under the zlib/libpng license. It is developed and maintained by Alberto Demichelis.
