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}}

Call from within Lua code

See the end of Module:Rugby box for a simple example or Module:Infobox3cols or Module:Flag for more complicated examples.
