ਮੌਡਿਊਲ:Check for deprecated parameters

This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.

This Lua module is used on many pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own module sandbox. Consider discussing changes on the talk page before implementing them.

Module:If preview

Module:Check for deprecated parameters may be appended to a template to check for uses of deprecated parameters. It will place the page in a specific category, and display a preview message, when it finds deprecated parameter uses.

Note: due to the nature of deprecations, this module will often have no templates implementing it.

Usage

{{#invoke:check for deprecated parameters|check
|category=[[Category:<category_name>|_VALUE_]]
| old_param1 = new_param1 
| old_param2 = new_param2
| ....
| old_paramN = new_paramN
}}

-- This module may be used to compare the arguments passed to the parent
-- with a list of arguments, returning a specified result if an argument is
-- on the list
local p = {}

	return s:match('^%s*(.-)%s*$')
end

local function isnotempty(s)
	return s and trim(s) ~= ''

	-- create the table of deprecated values and their matching new value
	local args = frame.args

	-- loop over the parent args and see if any are deprecated
	local values = {}
	local ignoreblank = isnotempty(frame.args['ignoreblank'])

			end	
		end
	end
	
	-- add results to the output tables
	local res = {}
	if #values > 0 then

		if isnotempty(preview) then
			preview = require('Module:If preview')._warning({
				preview
			})
		end
		-- Kind of dangerous to trust that this is never nil, but I guess it's
		-- preferable to display that the use of the module is broken rather than
		-- have some sort of tracking category for pages which have an unknown
		-- parent tracking template.
		local category = frame.args['category']
		for k, v in pairs(values) do
			local c = category:gsub('_VALUE_', v)
			table.insert(res, c)
			if v == '' then
				-- Fix odd bug for | = which gets stripped to the empty string
				-- and breaks category links
				v = ' '
			end
			local p = preview:gsub(
				'_VALUE_',
				'"'..v..'". Replace with "'..dep_values[v]..'".'
