Module:Warning

This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected.

This module simply unifies the formatting of all warning messages similar to Module:Error. Currently, it is plain text, but custom formatting may be applied after discussion in the talk page. Warnings are displayed above the preview when previewing an edit.

Usage

local warn = require('Module:Warning')
warn("Message")
warn(("TypeWarning: %s"):format(warning), level)

local libraryUtil = require('libraryUtil')

local wrapper = "%s" -- wikitext formatting
local msg_loc = "Lua warning in %s at line %d: %s."
local msg = "Lua warning: %s."

return function (message, level)
	libraryUtil.checkType('warn', 2, level, 'number', true)
	level = level or 1
	if level > 0 then
		local _, location = pcall(error, '', level+2)
		if location ~= '' then
			location = mw.text.split(location:sub(1,-3), ':%f[%d]')
			message = msg_loc:format(location[1], location[2], message)
		else
			message = msg:format(message)
		end
	else
		message = msg:format(message)
	end
	mw.addWarning(wrapper:format(message))
end
