Module:Random TAFI

释义

local p = {}

-- Named argument |list= used, like: {{#invoke:Random TAFI|choose|list=#item1 #item2 #item3}}

function p.choose(frame)

if mw.isSubsting() then

math.randomseed(mw.site.stats.edits + mw.site.stats.pages + os.time() + math.floor(os.clock() * 1000000000))

-- Generates a different number every time the module is called, even from the same page.

-- This is because of the variability of os.clock (the time in seconds that the Lua script has been running for).

local list = frame.args.list -- List of articles inputed via a single paramtere

local articles = mw.text.split(list, '#') -- Split list into an array of substrings (each containing an article).

local chosen = articles[math.random(2, #articles)] -- Note: First substring is empty as list begins with a #

return mw.text.trim(chosen) -- Trim whitespace before returning

else return "Error: Must be substituted – use {{subst:#invoke: ... }}"

end

return p
