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

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
