-- DESCRIPTION:
--    This module allows templates to use translations from the shared Datasets on Commons
--
--    For example, this will use dataset https://commons.wikimedia.org/wiki/Data:Original/Template:Graphs.tab
--    to translate message with ID "source-table" with an argument $1 = "tablename" to a wikitext
--
--      {{#invoke:TNT | msg | Original/Template:Graphs.tab | source-table | tablename}}
--   

local p = {}

function p.msg( frame )
	local dataset, id
	local params = {}
	for k, v in pairs( frame.args ) do
		if k == 1 then
			dataset = v
		elseif k == 2 then
			id = v
		elseif type(k) == 'number' then
			table.insert(params, v)
		end
	end

    for _, row in pairs(mw.ext.data.get(dataset).data) do
    	local id2, msg = unpack(row)
    	if id2 == id then
    		local result = mw.message.newRawMessage(msg, unpack(params))
    		return result:plain()
    	end
    end
end

-- Converts first parameter to a interwiki-ready link. For example, it converts
-- "Sandbox/Sample.tab" -> 'commons:Data:Sandbox/Sample.tab'
function p.link( frame )
	local dataset = 'Data:' .. (frame.args[1] or '')
	if mw.site.siteName == 'Wikimedia Commons' then
		return dataset
	else
		return 'commons:' .. dataset
	end
end
