Cosmo is a portable scripting language loosely based off of Lua. Cosmo easily allows the user to extend the language through the use of Proto objects, which describe the behavior of Objects. For example the following is a simple Vector Proto which describes behavior for a Vector-like object.
proto Vector
func __init(self)
self.vector = []
self.x = 0
end
func __index(self, key)
return self.vector[key]
end
func push(self, val)
self.vector[self.x++] = val
end
func pop(self)
return self.vector[--self.x]
end
end
let vector = Vector()
for (let i = 0; i < 4; i++) do
vector:push(i)
end
for (let i = 0; i < 4; i++) do
print(vector:pop() .. " : " .. vector[i])
