local function toTableEnd(t, pos) -- Sends the value at position pos to the end of array t, and shifts the -- other items down accordingly. return tinsert(t, tremove(t, pos)) end

local p = {}

function p.getCategoryName(cats, protType, protLevel, namespace, reason, expiry) --	-- Gets a category name from the category table, given a combination of	-- the protection type, the protection level, the namespace number, the	-- reason for protection, and the expiry date.	-- cats = cats or categories

--	-- Define the initial order to test properties in. The subtable position	-- is the order the properties will be tested in, and the pos value in	-- each subtable is the position of the value in the category key.	-- local properties = { {pos = 5, val = expiry}, {pos = 3, val = p.matchNamespace(namespace)}, {pos = 4, val = reason}, {pos = 2, val = protLevel}, {pos = 1, val = protType} }

--	-- Validate reason, and if it is specified as a "namespaceFirst" reason,	-- move the namespace subtable to the end of the properties table.	-- This is necessary to accommodate reasons like "vandalism", as the old	-- template used namespace categories rather than	-- vandalism categories if they were available.	-- local behavior if not reason then behavior = 'reasonFirst' else behavior = behaviors[reason] end if behavior == 'namespaceFirst' then toTableEnd(properties, 2) -- move namespace to end elseif behavior == 'reasonFirst' then toTableEnd(properties, 3) -- move reason to end else error(reason .. ' is not a valid reason') end

--	-- Define the attempt order. Properties with no value defined are moved	-- to the end, where they will later be given the value "all". This is	-- to cut down on the number of table lookups in the cats table, which	-- grows exponentially with the number of properties with valid values.	-- We keep track of the number of active properties with the noActive	-- parameter.	-- local active, inactive = {}, {} for i, t in ipairs(properties) do		if t.val then active[#active + 1] = t		else inactive[#inactive + 1] = t		end end local noActive = #active local attemptOrder = active for i, t in ipairs(inactive) do		attemptOrder[#attemptOrder + 1] = t	end

--	-- Check increasingly generic key combinations until we find a match.	-- If a specific category exists for the combination of properties	-- we are given, that match will be found first. If not, we keep	-- trying different key combinations until we match using the key	-- "all-all-all-all-all".	--	-- To generate the keys, we index the property subtables using a	-- binary matrix with indexes i and j. j is only calculated up to	-- the number of active properties. For example, if there were three	-- active properties, the matrix would look like this, with 0	-- corresponding to the string "all", and 1 corresponding to the	-- val field in the property table:	-- 	--  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 properties are set	-- to the string "all".	--	-- A key for the category table is constructed for each value of i.	-- The correct position of the value in the key is determined by the	-- pos field in the property table.	-- for i = 1, 2^noActive do		local key = {} for j, t in ipairs(attemptOrder) do			local pos = t.pos local val = t.val if j > noActive then key[pos] = 'all' else local quotient = i / 2 ^ (j - 1) quotient = ceil(quotient) if quotient % 2 == 1 then key[pos] = val else key[pos] = 'all' end end end key = tconcat(key, '-') mw.log(key) -- for debugging local attempt = cats[key] if attempt then return attempt end end error('No category match found; please define the category for key "all-all-all-all-all"') end
