Module:Carousel

p = {}-- carousel returns one of a list of image filenames---- the index of the one chosen increments every 'switchsecs'-- which is a parameter giving the number of seconds between switches-- 3600 would switch every hour-- 43200 would be every 12 hours-- 86400 would be daily (the default)---- The list of filenames is in a named submodule, so everyone can have their own list.-- For Komodobish (the default), the module is [[Module:Carousel/Komodobish]].-- For Serial Number 54129, the module is [[Module:Carousel/54129]].-- See https://www.how.com.vn/wiki/en/Special:PrefixIndex/Module:Carousel/---- {{#invoke:carousel | main | name = name-of-datamodule | switchsecs = number-of-seconds }}-- {{#invoke:carousel | main | name = 54129 | switchsecs = 10 }} for 10 sec switches using [[Module:Carousel/54129]]-- {{#invoke:carousel | main }} for 24 hours between switches using the default data module--p.main = function(frame)-- get parameter switchsecs; if NaN or less than 1, set defaultlocal switchtime = tonumber(frame.args.switchsecs) or 86400if switchtime < 1 then switchtime = 86400 end-- get parameter dataname; if missing, use defaultlocal dataname = frame.args.name or mw.text.trim(frame.args[1]) or ""if dataname == "" then dataname = "Komodobish" end-- there should be a named data module as a submodulelocal imgs = require("Module:Carousel/" .. dataname)local numimgs = #imgs-- 'now' increments by 1 every switchtime secondslocal now = math.floor( os.time() / switchtime )-- set an index between 1 and number of imageslocal idx = now % numimgs + 1return imgs[idx]endreturn p
