[purge]
[↓ jump to module code ↓]

If the {{Tr}} cached data needs to be purged, purge Module:Tr/loaddata or invoke {{#invoke:Tr|purge|lang=<lang code>}} in the case if you need to purge data for the specific language.

-- Note: 
-- It seems that objects/lists stored via luacache have a limit on the number of entities,  which is about 8k.
-- Any object/list which has more then 8k entities or having such a large sub-object/sub-list will be truncated.
-- Therefore, we encode the data into a string to get around this problem.

local cache = mw.ext.LuaCache

return {
	
	load = function(lang)
		local status, result = pcall(function ()
			return mw.text.jsonDecode(cache.get('tr__database-'..lang))
		end)
		if status then
			return result
		else
			-- fallback
			local info = require('Module:Tr/db-'..lang) -- return table of mw.loadData() has a metatable, can not be used for cache.set and mw.loadData.
			
			-- add on wiki language list
			info.onWikiLangList = { ['ko'] = true }
			
			-- cache it. 
			-- This cache can be purged by:
			-- * purge Module:tr/db-<lang> or Module:tr/db-<lang>/doc page
			-- * lua code: require('Module:Tr/loaddata').purge(<lang>)
			-- * template code: {{#invoke:tr|purge|lang=<lang>}}
			cache.set( 'tr__database-'..lang, mw.text.jsonEncode(info))
			return info
		end
	end,
	
	purge = function(lang)
		cache.delete( 'tr__database-'..lang)
	end
