Re: Is this possible? (garbage collect and weak tables)

[Mark Hamburg <mark@...>]

You can also set the translators table to auto-populate by giving it  
an appropriate __index metamethod.

module("translators", package.seeall)

local translators = {}
setmetatable(translators, {__mode = "v", __index = function( t, k )  
local v = { }; t[ k ] = v; return v; end })
local mt = {}

-- If there is not a suitable translator (for the given key and  
language),
-- create a new one and store it in a weak-valued table so it does not
-- linger there for ever.
mt.__index = function(tab, key)
  local user = inconcert.authUser or {languageId=14346,  
codepage="UTF-8"}
  local translator = translators[key][user.languageId]
  if not translator then
      translator = i18nlib.Translator{domain=key, language =  
user.languageId, codepage = user.codepage, transliterate=false}
      translators[key][user.languageId] = translator
  end
  return translator
end

setmetatable(_M, mt)
