Class Library Differences - 30log vs Middleclass

[3CordGuy]

Hey Guys

I was searching the forums for an answer to this one today but couldn't find much on the topic.

I've selected 30log when I first started my initial "test project" with which to learn LÖVE and dive deeper into Lua. I really like it so far, but I'll admit I'm just now starting to dive into OOP.

When reading the forums, I've noticed a lot of users tend to suggest Middleclass as their goto class library. I can't help but be curious if I'm missing out on some functionality that makes it more prominent here on the forums???

What's the big difference or draw?

When I was looking at the docs on github for Middleclass, I didn't really see how you declare specific class variables before the object instance is initialized... If that makes sense.

Thanks for any illumination!

middleclass is the general recommendation as it has about the right level of functionality that most people need from a class-inheritance system. Mixins in particular are one of the stronger features.

30log also has a lot of good functionality, and there's no reason to bash on it.

30log is actually kind of crap in that Inheritance is broken. I highly recommend either using middleclass or hump.class.

Enlighten me, please.
I'd love examples.

You might be thinking of the similarly named 32log, which I've skewered like something that gets skewered a lot, three and a half years ago.

Not that 30log is free of faults. It uses a deep_copy implementation that is in some ways a deep copy implementation, some of the time. It handles non-tree datastructures much the same way SLib does. Keys are never copied. If you pass in a third argument, it becomes a shallow copy that only brings in values of a specific type, used to make sure mixins only mix in functions. Yep, deep_copy is one crazy function.

I didn't really want to take a close look, you can probably find much more wrong with it if you were willing to look at the code for more than five minutes

I didn't really want to start a war here, I just wanted to know why people preferred one over the other... but if it gets super technical, then it may be over my head anyway.

[Karai17]

Nah, there is no war here. the 30/32log libs annoy me because their main goal is to use the least amount of lines to prove a point, instead of provide the most amount of function to provide a service. Middleclass and hump.class are both top notch libraries (hump also has lots of other terrific libs) and I recommend using either.

I like Moonscript's class implementation.

Which is described here, by the way.

Thanks for the link. That looks a bit too complex for my skill level. I'm still wrapping my brain around the basics.
