![]() | This Lua module is used on 1,200+ pages, so changes to it will be widely noticed. Please test any changes in the module's /sandbox or /testcases subpages. Please consider discussing changes on the talk page before implementing them. |
This module creates an html message with class "error". It is a replacement for {{error}} - please see the documentation page there for usage instructions.
-- This module implements {{error}}. local p = {} local function _error(args) local tag = mw.ustring.lower(tostring(args.tag)) -- Work out what html tag we should use. if not (tag == 'p' or tag == 'span' or tag == 'div') then tag = 'strong' end -- Generate the html. return tostring(mw.html.create(tag) :addClass('error') :wikitext(tostring(args.message or args[1] or error('no message specified', 2))) ) end function p.error(frame) local args if type(frame.args) == 'table' then -- We're being called via #invoke. The args are passed through to the module -- from the template page, so use the args that were passed into the template. args = frame.args else -- We're being called from another module or from the debug console, so assume -- the args are passed in directly. args = frame end -- if the message parameter is present but blank, change it to nil so that Lua will -- consider it false. if args.message == "" then args.message = nil end return _error(args) end return p
