Template:Navseasoncats/doc

Searching behavior
Multi-year seasons/office terms/numerical ranges are acceptable as long as the duration/range size remains constant, and no years/numbers are irregularly skipped. The length of each duration/range is automatically determined from the originating category name, up to and including 10 years. MOS:DATERANGE compliance is preferred, but some deviation is allowed and tracked. Category redirects are followed, and tracked for either MOS contravention (to be corrected) or for navigational aid (no error). The gap size between successive durations/ranges is also automatically determined, up to and including 5 years if a surrounding category is found, and defaults to 0 (e.g. 1995–96 → 1996–97).

Automatically condensed year display is supported for  categories only (but can be easily expanded as needed), for gaps up to and including 5 years, and defaults to 1. To skip gaps up to 10–15 years (position-dependent) in any year categories, use yes.

Limitations

 * Season/office term categories do not work for any years BC, which will be hidden, because no working examples were found.
 * Decade categories recognize BC, but not BCE, because no working examples were found.
 * Automatically condensed year display is supported for  categories only, due to their consistency. Use yes as desired elsewhere.
 * Automatically condensed Olympics display is not supported due to peculiarities; use Winter Olympics by year category navigation, etc., instead.
 * Ordinal words do not work above the ninety-ninth, because no higher working examples were found.
 * General: for large, permanent gaps between successive categories, or when the base category name changes, use Category pair in addition to Navseasoncats on both sides of the gap/name change. Even if Navseasoncats is isolated, it has the benefit of confirming the absence of nearby categories to the reader or maintainer.

Usage

 * Typical usage


 * Specify a minimum and/or maximum year to display


 * To skip gaps in year categories


 * To not automatically follow Category redirects


 * Exceptional cases
 * &mdash; to behave as if placed on cat; consider using Category pair instead of cat

Testing & debugging
To test the output of the template on a particular category name, use the testcase parameter, and testcasegap if necessary:






 * Which is technically an inappropriate category for Navseasoncats placement, but it best shows the yes behavior for all element variants (blue, red/grey, hidden, and redirect), and would otherwise display as:

Tracking categories


If the template encounters an issue, it displays an error message and/or places the category into one or more of the following tracking categories:
