This is the documentation page for ᱢᱳᱰᱩᱞ:Check for unknown parameters
This template is used on ᱘,᱒᱐᱐,᱐᱐᱐+ pages. To avoid large-scale disruption and unnecessary server load, any changes to it should first be tested in its /sandbox or /testcases subpages or in your own user subpage. The tested changes can then be added to this page in a single edit. Please consider discussing any 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 articles, 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 is protected from editing. |
This module may be appended to a template to check for uses of unknown parameters.
Usage
ᱥᱟᱯᱲᱟᱣBasic usage
ᱥᱟᱯᱲᱟᱣ{{#invoke:check for unknown parameters|check |unknown=[[Category:Some tracking category]] |arg1|arg2|...|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
ᱥᱟᱯᱲᱟᱣThis 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
ᱥᱟᱯᱲᱟᱣ{{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:TemplatePar - similar function (originally from dewiki)
- Template:Parameters and Module:Parameters – generates a list of parameter names for a given template
- 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
