Add New Code in New File to Existing Addon

[eoblaed]

I have several addons that still use the old GetMapNameByID() API call. This is now a 'nil'.

I wrote a thin wrapper function that looks up the old worldID, converts it to the new style UiMapID, and returns C_Map.GetMapInfo(newid).name. The code works when I embed it directly into the various .lua files of the addon (but, that's not a great solution).

What I'm trying to do is create a new file, MapCompat.lua, in such a way that will allow the other pre-existing lua files in the addon to see the GetMapNameByID() call in that new .lua file.

Not having authored an addon before, there's a seemingly labyrinthine combination of .xml, .toc, etc, and I haven't quite hit on the right combination of things to do what I want to do.

Any pointers?

Thanks!
