![]() | This Lua module is used in system messages, and on approximately 21,000,000 pages, or roughly 34% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the module's /sandboxor/testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them. |

Module:Check for unknown parameters is used to check for uses of unknown parameters in a template or module. It may be appended to a template at the end or called directly from a module.
To sort entries into a tracking category by parameter, use:
{{#invoke:Check for unknown parameters|check|unknown=[[Category:Some tracking category|_VALUE_]]|arg1|arg2|arg3|argN}}
To sort the entries into a tracking category by parameter with a preview error message, use:
{{#invoke:Check for unknown parameters|check|unknown=[[Category:Some tracking category|_VALUE_]]|preview=unknown parameter "_VALUE_"|arg1|arg2|...|argN}}
For an explicit red error message, use:
{{#invoke:Check for unknown parameters|check|unknown=<span class="error">Sorry, I don't recognize _VALUE_</span>|arg1|arg2|...|argN}}
To use Lua patterns, use:
{{#invoke:Check for unknown parameters|check|unknown=[[Category:Some tracking category|_VALUE_]]|preview=unknown parameter "_VALUE_"|arg1|arg2|...|argN|regexp1=header[%d]+|regexp2=date[1-9]}}
To call from a module, use:
local checkForUnknownParameters = require("Module:Check for unknown parameters")
local result = checkForUnknownParameters._check(validArgs, args)
Where the first set of args are the module args below and the second set of args are the parameters that are checked.
arg1
, arg2
, ..., argN
, are the known parameters.|1|2|arg1|arg2|...
.|regexp1=header[%d]+
, |regexp2=date[1-9]
, |regexp3=data[%d]+[abc]?
). This is useful when there are many known parameters which use a systematic pattern.|unknown=
– what happens when an uknown parameter is used. Typically use either a tracking category to place pages that use unknown parameters, or an error.|preview=
– the text to be displayed when in preview mode and an unknown parameter is used._VALUE_
keyword, if used, will be changed to the name of the parameter. This is useful for either sorting the entries in a tracking category, or for provide more explicit information.|ignoreblank=1
– by default, the module makes no distinction between a defined-but-blank parameter and a non-blank parameter. That is, both unlisted |foo=x
and |foo=
are reported. To only track non-blank parameters use |ignoreblank=1
.|showblankpositional=1
– by default, the module ignores blank positional parameters. That is, an unlisted |2=
is ignored. To include blank positional parameters in the tracking use |showblankpositional=1
