Module:URL

Module documentation[view] [edit] [history] [purge]

This module implements {{URL}} and {{URL2}}. Please see the template page for documentation.

Lua interface

The p._url(url, text, msg) function may be used by other Lua modules. It returns a formatted Wikitext for the given URL, made suitable for line wrapping using . It takes the following parameters:

url

REQUIRED. The URL to format.

text

OPTIONAL. Display text to put in the Wikitext link. Defaults to a pretty version of the URL.

msg

OPTIONAL. String. If content is false, n or N, do not emit a help message (using {{tlx}}) when URL is not given.

Example

The following module emits a prettified link to log the user out. It will wrap correctly to most widths.

local url = require('Module:URL')._url
local p = {}

p.main = function(frame)
    return url("https://en.wikipedia.org/wiki/Special:UserLogout")
end

return p
