Module:Transclusion count

Fetches usage data for highly-transcluded templates. Uses bot-updated values from subpages of Module:Transclusion_count/data/ when available.

Usage

{{#invoke:Transclusion count|fetch|number of transclusions|use + notation|all-pages=|demo=}}

• number of transclusions: is a static number of times the template has been transcluded, to use when values cannot be read from the database. This value will be ignored if transclusion data is available for the current page.
• demo=Template_name: will use the transclusion count for the template at Template:Template_name instead of detecting what template it is being used on. Capitalization must exactly match the value used in Special:PrefixIndex/Module:Transclusion_count/data/.

{{#invoke:Transclusion count|tabulate}}

• Used to generate Wikipedia:Database reports/Templates transcluded on the most pages.

Notices

• The number of transclusion count is generated via subpages of Module:Transclusion count/data when is available and is automatically updated via a bot.
