Lua error in package.lua at line 80: module 'Module:Transclusion_count/data/C' not found.

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. 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
}}

Templates invoking this module

The following is a list of some of the templates which invoke this module, with the associated category for each.

For a more up-to-date list, search for the "check for unknown parameters" within the template namespace.

See also

  • Category:Unknown parameters (0) (category page can have {{Unknown parameters category}})
  • 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
