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= |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|}}} }}{{#invoke:Check for unknown parameters|check | unknown = {{main other|[[Category:Some tracking category|_VALUE_]]}} | preview = unknown parameter "_VALUE_" | name | height | weight | website }}
