-- In this model, we register labels as we need them.
-- This has the downside that we cannot have multiple labels with the same English text.

local MyLangLib

	static function trans(text)
		local key = lang.find_registered(text)
		if key == 0 then
			key = lang.register(text)
		end
		return key

		return lang.get_localised(MyLangLib.trans(text))
	end
end

MyLangLib.trans("Hello, world!") -- We want to use this inside of the callback, but we need to register it now.
menu.my_root():action(MyLangLib.trans("Say Hello"), {}, "", function()
	util.toast(MyLangLib.str_trans("Hello, world!"))
end)

-- Then after they're all registered, we can do translations via find_registered.

lang.translate(lang.find_registered("Say Hello"), "Sag Hallo")
lang.translate(lang.find_registered("Hello, world!"), "Hallo, Welt!")
