Template:Year parameter usage check

Template documentation[view] [edit] [history] [purge]

This template is used on approximately 170,000 pages.
To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

A monitoring template, to track use of by-year templates where:

the year is supplied as one or more parameters, and
that parameter is different from the year used in the title, or
the title does not include a year

Purpose

This template is intended as a temporary monitoring and diagnostic tool.

Most of the category-by-year header templates are designed to be used on pages where the year is part of the page title. In such cases, the year does not need to be supplied as a parameter, because it can be grabbed from the title using {{Title year}}.

If all uses of a template are on pages which do have a year in the title which matches the year parameters, then the by-year parameters are redundant, and the template can be rewritten to remove them.

This template will track the exceptions, if any.

The template is currently used in {{Year by category}}. It was previously used in e.g. {{EstcatCountry}}, {{DisestcatUSstate}} and {{Eiei-year}} to check and clean up all parenting before those templates were rewritten with parameterless dating.
