Replacing AceOO with metatables

[LaoTseu]

Someone mentioned to use two metatables to replace the AceOO stuff. Is there an article or example that we can point to to explain how to do this? I'm thinking of ppl that do normally do lua OO but would like to undertake the conversion of an addon that is no longer maintain.

To prevent the thread to go further off-topic, you should ask this in a brand new thread.

I moved your posts to a new thread.

On the topic:
I don't 100% remember how AceOO worked, never liked it, never extensively used it.
But the basic OO principles are really easy to "fake" in Lua.

I'll look for an article when i get home, maybe i can find a good one again. I'm sure others will have them around as well, or will just explain here.

A part of AceOO were used in AceAddon-2.0 and AceModule-2.0 (or whatever allowed to create modules). This part is taken care of by AceAddon-3.0.

If the addon called AceOO directly, there might be more things to do.

Here a basic OOP stub:

The idea is to use the "__index" operation of lua metable that is used to look up for missing keys in other tables (or to be handled by a function, but we are not interested in that feature).

For an introduction that is not specific to WoW (but applies in all cases to WoW addons), here are links into a book written by one of the Lua architects:
