metatables

[karlis]

hey there, i just tried to use metatables for the first time, and i failed.

it just doesn't call the __newindex function.

what i want to do is when settings table is changed also global variable is changed, but it doesn't work.

  
.. 
settings=getSettings() --that is valid table 
setmetatable(settings,{ 
  __newindex=function(_,key,value) 
    _G[key]=value 
  end 
}) 
.. 
  

PS:yes, i know it would be better just calling the tables, but as code already have some of the variables called 150times, and its a long mess already, i don't want to do that just to save KB or two.

Try __index instead.

__index is called when you get variable, __newindex, when you set it.

I don't see any point of using metatables here. Can you explain "why"?

[karlis]

i need to use tables to get current, backuped(in case of cancelation), default and probably server override options.

but now i think i figured to just use default value table as refference what to take from _G for current settings, therefore leaving no need for this.

still i'd like to know what i did wrong so next time i can do it.
