The [https://bambots.brucemyers.com/TemplateParam.php Template Parameters tool] is available for viewing template parameter usage in articles. It works with [[Wikipedia:TemplateData|TemplateData]] to show the frequency of parameter name usage in a template's mainspace transclusions, along with whether or not each parameter is listed in that template's TemplateData code as a supported parameter. For a required parameter, it can display a list of pages where the template is missing that parameter. The tool also shows commonly used values for each parameter. Each report is updated monthly and does not reflect changes made to articles or to the TemplateData code after the report's generation.

== Usage ==
Example: 
<div style="background:#ddd">
* {{tl|Infobox lighthouse}}/documentation: {{Slink|Template:Infobox_lighthouse|TemplateData}} &rarr; "''[https://bambots.brucemyers.com/TemplateParam.php?wiki=enwiki&template=Infobox+lighthouse Click here] to see a monthly parameter usage report ...''" &rarr; [https://bambots.brucemyers.com/TemplateParam.php?wiki=enwiki&template=Infobox+lighthouse].
</div>
===Parameters===
<pre>
{{Template parameter usage
| 1    = <!-- template:name, default=pagename -->
| lc   = <!-- yes/no -->
| label= <!-- keywords like "for", or free labeltext -->
}}
</pre>
:All parameters are optional, and have a default

By default, the template links for the template page: 
:<nowiki>{{Template parameter usage}}</nowiki> &rarr; {{Template parameter usage}} [for this page]
One can enter a template name:
:<nowiki>{{Template parameter usage|Infobox film}}</nowiki> &rarr; {{Template parameter usage|Infobox film}} 

Optional:
* {{para|lc|yes}} for lowercase "see":  {{Template parameter usage|lc=yes|Infobox film}} 
* Entering {{para|1|Template:Infobox film}} is accepted (namespace is removed). Editor friendly, using a positional parameter.
: When {{para|1}} is used, "this template" text changes: &rarr; {{Template parameter usage|1=Infobox film}}
* {{para|label}} sets the visible text; it does not change the target link:
::{{para|label}} default &rarr; {{Template parameter usage|1=Infobox film}}
::{{para|label|none}} &rarr; {{Template parameter usage|1=Infobox film|label=none}}
::{{para|label|for}} &rarr; {{Template parameter usage|1=Infobox film|label=for}}
::{{para|label|FooBar}} &rarr; {{Template parameter usage|1=Infobox film|label=FooBar}}
* {{para|based|yes}} adds the text "based on this TemplateData" to the end of the template (or "based on its TemplateData" if {{para|1}} is also used).

The template is included in transclusions of {{Tl|TemplateData header}}.

== Error reports ==

{{tl|Template parameter usage}}

By default, it links a report for the template-page being viewed. To link a report for a different template-page, pass it as the first parameter:

:{{tlx|Template parameter usage|Example}} makes a link to the error report for [[Template:Example]]:

:&rarr; {{Template parameter usage|Example}}

The first character can be made lowercase to follow on at the end of a sentence:
:<code>Blah, {{tlp|Template parameter usage|2=lc=yes}}</code> → Blah, {{Template parameter usage|lc=yes}}

== TemplateData ==
{{TemplateData header}}
