-- function to scan argument list for pattern-- Parameters:-- args = an argument dict that will be scanned for one or more patterns-- patterns = a list of Lua string patters to scan for-- other = a list of other argument specification lists-- each element o corresponds to a new argument to produce in the results-- o[1] = key in new argument list-- o[2] = prefix of old argument-- o[3] = suffix of old argument-- Returns:-- new argument list that matches patterns specified, with new key names---- This function makes the Lua module scalable, by specifying a list of string patterns that-- contain relevant arguments for a single graphical element, e.g., "period(%d+)". These-- patterns should have exactly one capture that returns a number.---- When such a pattern is detected, the number is extracted and then other arguments-- with the same number is searched for. Thus, if "period57" is detected, other relevant-- arguments like "period57-text" are searched for and, if non-empty, are copied to the-- output list with a new argument key. Thus, there is, and-- "period(%d+)" detects period57, the code will look for "period57-text" in the input-- and copy it's value to "text" on the output.---- This function thus pulls all relevant arguments for a single graphical item out, and-- makes an argument list to call a function to produce a single element (such as a bar or note)function p._scanArgs(args,patterns,other) local result = for _, p in pairs(patterns) do for k, v in pairs(args) do local m = tonumber(mw.ustring.match(k,p)) -- if there is a matching argument, and it's not blank -- and we haven't handled that match yet, then find other -- arguments and copy them into output arg list. -- We have to handle blank arguments for backward compatibility with the template -- we check for an existing output with item m to save time if m and v ~= "" and not result[m] then local singleResult = for _, o in ipairs(other) do local foundVal = args[(o[2] or "")..m..(o[3] or "")] if foundVal then singleResult[o[1]] = foundVal end end -- A hack: for any argument number m, there is a magic list of default -- colors. We copy that default color for m into the new argument list, in -- case it's useful. After this, m is discarded singleResult.defaultColor = defaultColor[m] result[m] = singleResult end end end -- Squeeze out all skipped values.
