Module:Check for unknown parameters/doc

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|...|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.

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
}}
