Template:Navseasoncats/doc

About
Navseasoncats is intended to be a minimal-input, near-universal template for navigating most sequential categories.

Searching behavior
Most multi-year seasons/office terms/numerical ranges are acceptable, as long as the season duration/term length/range size is <= 10, and the gap between seasons is <= 6. For series exceeding either of these criteria, see/use Irregular navseasoncats.

The length of each season 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 for regular series with seasons > 1 year long. Category redirects are followed, and tracked for either MOS contravention (to be corrected) or for navigational aid (no error). The gap size between successive seasons is also automatically determined, up to and including 5 years, and defaults to 0 (e.g. 1995–96 → 1996–97).

Automatically condensed years are 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 of up to 25 years in any year categories, use yes.

Limitations

 * Numerical limitations & AD/BC/E
 * 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.
 * Ordinal & numeral words do not work above the ninety-ninth & ninety-nine, because no working examples were found.
 * Condensation
 * Automatically condensed Olympics display is not supported due to peculiarities; use Winter Olympics by year category navigation, etc., instead.
 * Automatically condensed years are supported for  categories only, due to their consistency; use yes as desired elsewhere.
 * Work-arounds
 * Base-name changes: create at least 2 logically numbered R from category navigation (1 forward & 1 backward), to join both related series.
 * Unaccounted-for name+number conventions: where a fixed number is part of the prefix text, e.g. Chapter 11 bankruptcies, a non-breaking space may force the template to work. See this fix, where title year skipped over 11 as part of a word rather than a discrete number. (This has been accounted for and is no longer required in this example.)
 * General: for large, permanent gaps† between successive categories, use Succeeding category, Preceding category, Category pair, as needed, in addition to Navseasoncats on both sides, or in the middle, of the gap. Even if Navseasoncats is isolated, it has the benefit of confirming the absence of nearby categories to the reader or maintainer. †Permanent gaps, where there is confirmed to be an absence of data, and not just a current, yet to be filled, gap on Wikipedia.

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
