Module:Check for unknown parameters/doc
This is the documentation page for Module:Check for unknown parameters
File:Ambox important.svg | This Lua module is used in MediaWiki:Abusefilter-warning-DS, and on approximately 18,200,000 pages, or roughly 1117250% 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 /sandbox or /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. |
File:Lua-Logo.svg | This module depends on the following other modules: |
This module may be appended to a template to check for uses of unknown parameters. Unlike many other modules, this module is not implemented by a template.
Usage
Basic usage
{{#invoke:Check for unknown parameters|check
|unknown=[[Category:Some tracking category]]
|arg1|arg2|arg3|argN}}
or to sort the entries in the tracking category by parameter with a preview error message
{{#invoke:Check for unknown parameters|check
|unknown=[[Category:Some tracking category|_VALUE_]]
|preview=unknown parameter "_VALUE_"
|arg1|arg2|...|argN}}
or for an explicit red error message
{{#invoke:Check for unknown parameters|check
|unknown=<span class="error">Sorry, I don't recognize _VALUE_</span>
|arg1|arg2|...|argN}}
Here, arg1
, arg2
, ..., argN
, are the known parameters. Unnamed (positional) parameters can be added too: |1|2|argname1|argname2|...
. Any parameter which is used, but not on this list, will cause the module to return whatever is passed with the unknown
parameter. The _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.
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
.
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
.
Lua patterns
This module supports Lua patterns (similar to regular expressions), which are useful when there are many known parameters which use a systematic pattern. For example, Infobox3cols
uses
regexp1 = "header[%d]+",
regexp2 = "label[%d]+",
regexp3 = "data[%d]+[abc]?",
regexp4 = "class[%d]+[abc]?",
regexp5 = "rowclass[%d]+",
regexp6 = "rowstyle[%d]+",
regexp7 = "rowcellstyle[%d]+",
to match all parameters of the form headerNUM
, labelNUM
, dataNUM
, dataNUMa
, dataNUMb
, dataNUMc
, ..., rowcellstyleNUM
, where NUM is a string of digits.
Example
{{Infobox
| above = {{{name|}}}
| label1 = Height
| data1 = {{{height|}}}
| label2 = Weight
| data2 = {{{weight|}}}
| label3 = Website
| data3 = {{{website|}}}
}}<!--
end infobox, start tracking
-->{{#invoke:Check for unknown parameters|check
| unknown = {{Main other|[[Category:Some tracking category|_VALUE_]]}}
| preview = unknown parameter "_VALUE_"
| name
| height | weight
| website
}}
