This Lua module is used on approximately 20,700,000 pages, or roughly 876747% of all pages. 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. Consider discussing changes on the talk page before implementing them. |
This Lua module is used in MediaWiki:Abusefilter-warning-DS, and on approximately 20,700,000 pages, or roughly 876747% 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. |
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 module may be appended to a template to check for uses of unknown parameters.
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, template:infobox3cols uses
| regexp1 = header[%d][%d]* | regexp2 = label[%d][%d]* | regexp3 = data[%d][%d]*[abc]? | regexp4 = class[%d][%d]*[abc]? | regexp5 = rowclass[%d][%d]* | regexp6 = rowstyle[%d][%d]* | regexp7 = rowcellstyle[%d][%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 }}

- Module:Check for deprecated parameters – similar module that checks for deprecated parameters
- Module:Check for clobbered parameters – module that checks for conflicting parameters
- Module:TemplatePar – similar function (originally from dewiki)
- Template:Parameters and Module:Parameters – generates a list of parameter names for a given template
- Project:TemplateData based template parameter validation
- he:Module:ParamValidator – parameter validation system on hewiki, relies on TemplateData. module doc in English. checks the following:
- use of undeclared parameters
- use of parameters marked in templatedata "deprecated"
- mistyped (mainly, parameters declared in templatedata as "number" receiving non-numerical value)
- missing parameters marked in TemplateData as "required"
- understands aliases, and warns when more than one alias of a parameter is used
- cs:Module:CheckParameters – another parameter check system on cswiki that relies on TemplateData
- he:Module:ParamValidator – parameter validation system on hewiki, relies on TemplateData. module doc in English. checks the following:
