Module:Links

-- --| Creates links and changes wikitext when it detects external links --| Syntax --| --| --| Example: --| local p = {} --% This function generates a wiki link --@ url (string) The url to convert to wikitext --@ desc (string) The caption or description of the url --@ typ (string) The type of link, (local or ext) --: (string) A formated wikilink function p.link(url, desc, typ) local url = url or "" local lenUrl = mw.ustring.len(url) local uMatch = mw.ustring.match if typ == "ext" and (not uMatch(url, "%.") or lenUrl < 3) or lenUrl < 1 then return end local prefix = ""   local suffix = "" local separator = "|" if url:match("^[Cc]ategory:") and typ ~= "ext" then prefix = "[[:"   end    -- Adapt if url is external    if typ ~= "local" and (uMatch(url, "www%.") or uMatch(url, "^http"))            or typ == "ext" then        prefix = "[//"        if uMatch(url, "^http") then            prefix = "["        end        suffix = "]"        separator = " "    end    local desc = desc or ""    if mw.ustring.len(desc) < 1 then        separator = ""    end    return prefix .. url .. separator .. desc .. suffix end --% Entry point for function that generates a wiki link --@ frame (table) Contains frame from invoked module --: (string) A formated wikilink function p.main(frame)    local args = require("Dev:Arguments").getArgs(frame)    return p.link(args[1] or args.page, args[2] or args.desc, args.type) end --% Entry point for function that generates several wiki links --@ frame (table) Contains frame from invoked module --: (string) A formated string containing one or more wikilinks function p.batch(frame)    local args = require("Dev:Arguments").getArgs(frame)    local separator = args.separator    local delimiter = args.delimiter    return p.createLinkBatch(args, separator, delimiter) end --% This creates and formats many links --@ links (table) a table containing links, e.g. {'Lua label1 type', 'www.google.com google ext'} --@ separator (string) a separator between each link --@ delimiter (string) an optional delimiter that will separate the label, link & type --: (string) A formated string containing one or more wikilinks function p.createLinkBatch(links, separator, delimiter)    local linkTable = {}    local linkBatch = ""    local linkUrl = ""    local linkLabel = ""    local linkType = ""    local delimiter = delimiter or "%s"    local separator = separator or " • "    local linkLen = 0    for _, linkData in ipairs(links) do        linkLen = linkData:len        linkType = linkData:sub(linkLen - 2)        if linkType ~= "ext" and linkType ~= "int" then            linkType = ""        else            linkData = linkData:sub(1, linkLen - 4)        end        linkTable = mw.text.split(linkData, delimiter)        linkUrl = linkTable[1]        linkLabel = linkTable[2]        linkBatch = linkBatch .. p.link(linkUrl, linkLabel, linkType) .. separator    end    return linkBatch end return p
