---- The old protection templates used an ad-hoc protection category system, -- with some templates prioritising namespaces in their categories, and -- others prioritising the protection reason. To emulate this in this module -- we use the config table cfg.reasonsWithNamespacePriority to set the -- reasons for which namespaces have priority over protection reason. -- If we are dealing with one of those reasons, move the namespace table to -- the end of the order table, i.e. give it highest priority. If not, the -- reason should have highest priority, so move that to the end of the table -- instead. -- table.insert(order, table.remove(order, self.reason and cfg.reasonsWithNamespacePriority[self.reason] and 2 or 3)) ---- Define the attempt order. Inactive subtables (subtables with nil "value" -- fields) are moved to the end, where they will later be given the key -- "all". This is to cut down on the number of table lookups in -- cfg.protectionCategories, which grows exponentially with the number of -- non-nil keys. We keep track of the number of active subtables with the -- noActive parameter. -- local noActive, attemptOrder do local active, inactive =, for i, t in ipairs(order) do if t.val then active[#active + 1] = t else inactive[#inactive + 1] = t end end noActive = #active attemptOrder = active for i, t in ipairs(inactive) do attemptOrder[#attemptOrder + 1] = t end end ---- Check increasingly generic key combinations until we find a match. If a -- specific category exists for the combination of key fragments we are -- given, that match will be found first. If not, we keep trying different -- key fragment combinations until we match using the key -- "all-all-all-all-all". -- -- To generate the keys, we index the key subtables using a binary matrix -- with indexes i and j. j is only calculated up to the number of active -- subtables. For example, if there were three active subtables, the matrix -- would look like this, with 0 corresponding to the key fragment "all", and -- 1 corresponding to other key fragments. -- -- j 1 2 3 -- i -- 1 1 1 1 -- 2 0 1 1 -- 3 1 0 1 -- 4 0 0 1 -- 5 1 1 0 -- 6 0 1 0 -- 7 1 0 0 -- 8 0 0 0 -- -- Values of j higher than the number of active subtables are set -- to the string "all". -- -- A key for cfg.protectionCategories is constructed for each value of i. -- The position of the value in the key is determined by the keypos field in -- each subtable. -- local cats = cfg.protectionCategories for i = 1, 2^noActive do local key = for j, t in ipairs(attemptOrder) do if j > noActive then key[t.keypos] = 'all' else local quotient = i / 2 ^ (j - 1) quotient = math.ceil(quotient) if quotient % 2
