A good OO lib

[rokit boy]

Can someone suggest me a very good OO lib with the syntax as close to this:

Code: Select all

class Class1 {

hi = 1
hi2 = 2 -- general fields

function Class1(as) -- constructor
hi2 = as
end

function getHi() -- methods
return hi
end

Then in another script:

Code: Select all

Class1 class1 = new Class1(12)

trol = class1.getHi()
print(trol)

Can someone suggest me one as close to that as possible? Or any class lib if what I just show is nowhere near possible in lua or any other thing similar to my examples.

I think Slither is your best bet. Here're some examples.

Obviuosly the syntax is not exactly like the one you proposed, but it's near enough.

Ok so I think it looks good but when is the __init__ and the __add__ called?
I'm pretty sure __init__ is the initialization but what is __add__?

__add__ is run when you try to add two instances.

Code: Select all

derpherp = derp + herp

You can look at the examples.

Thanks!

are there any other functions apart from __init__ and __add__ ?

[nevon]

Yes. __call__, __len__, __add__, __sub__, __mul__, __div__, __mod__, __pow__, and __neg__

They're all just aliases of the Lua standard metamethods.

[rokit boy]

Sow ill init be the constructor, __add,div,sub,mul,mod,pow,neg__ are mathematical and the rest I don't know.

Looking forward to making stuff with this.

What is __len__?

Btw. I smell python. Is it python inspired?

What is __len__?

The # operator. It is not overridable for tables in Lua 5.1 (though it will be for Lua 5.2).

Yes.
