Template:Year in Europe/doc

This is a navbox template intended for "Year in country" articles for European countries. Based on the input year, it contains all countries in Europe in that year, linked to the respective "Year in country" article, if that doesn't exist the "Decade in country" article, and if that doesn't exist either the "History of country" article.

This template is based on {{Europe topic}} and therefore uses mostly the same parameters. The template may not yet contain all former countries, though the goal is to make it accurate for all years after 1000.

Parameters

• {{{1}}} (first unnamed parameter): The year (required; if unspecified or not numeric an error message is given)
• {{{title}}}: A custom title (default: "<year> in Europe", linked if an article with that name exists)
• {{{state}}}: "expanded", "collapsed" or "autocollapse" (see {{collapsible option}})

Furthermore, the link to each country can be individually set using the following parameter names. If set to nothing it omits the country entirely. These parameters also work if a country is omitted by default because it didn't exist in the given year.

Current countries (ISO 3166-1 codes) AL – Albania AD – Andorra AM – Armenia AT – Austria AZ – Azerbaijan BY – Belarus BE – Belgium BA – Bosnia and Herzegovina BG – Bulgaria HR – Croatia CY – Cyprus CZ – Czech Republic DK – Denmark EE – Estonia FI – Finland FR – France GE – Georgia DE – Germany GR – Greece HU – Hungary IS – Iceland IE – Ireland IT – Italy KZ – Kazakhstan LV – Latvia LI – Liechtenstein LT – Lithuania LU – Luxembourg MK – Macedonia MT – Malta MD – Moldova MC – Monaco ME – Montenegro NL – Netherlands NO – Norway PL – Poland PT – Portugal RO – Romania RU – Russia SM – San Marino RS – Serbia SK – Slovakia SI – Slovenia ES – Spain SE – Sweden CH – Switzerland TR – Turkey UA – Ukraine GB – United Kingdom VA – Vatican City

It's technically possible to input non-integer years like 1976.5, but that wouldn't make much sense, and year articles are not likely to exist for such years.

Examples

Example with custom title and links:

{{Year in Europe|2000|title=Title|DK=Custom link for Denmark}} →

Note the (red) custom link for Denmark.

Code for adding countries

* {{Year in Europe/expr|{{{1}}}|{{{Code|♦}}}|Years|name=Country name}}

where "Code" is a unique country-specific parameter name, "Years" is a series of years identifying periods of existence of a country (see below), and "Country name" is the country name that should be used for links. If the short-form name that should be displayed is different (for example "Georgia (country)" vs. "Georgia"), the parameter |disp=display name should be added; for countries whose names require the article "the" the parameter |the=the is available. The sub-template {{Year in Europe/expr}} automatically compares the input year with the year criteria and creates the link.

"Years" is a series of up to six unnamed parameters where each pair of two identifies a time period in which the country existed. Omit either for an unbounded interval (since the first year or until the second year). Some examples:

Code	Interval	Country included in years
* {{Year in Europe/expr|{{{1}}}|{{{Code|♦}}}|1100|1300|name=Name}}	[1100, 1300)	1100–1300
* {{Year in Europe/expr|{{{1}}}|{{{Code|♦}}}|1100|1300|1500|1700|name=Name}}	[1100, 1300), [1500, 1700)	1100–1300 and 1500–1700
* {{Year in Europe/expr|{{{1}}}|{{{Code|♦}}}|1100|name=Name}}	[1100, +∞)	since 1100
* {{Year in Europe/expr|{{{1}}}|{{{Code|♦}}}| |1300|name=Name}}	(−∞, 1300)	until 1300
* {{Year in Europe/expr|{{{1}}}|{{{Code|♦}}}|1100|1300|1500|name=Name}}	[1100, 1300), [1500, +∞)	from 1100 until 1300 and after 1500
* {{Year in Europe/expr|{{{1}}}|{{{Code|♦}}}| |1100|1300|name=Name}}	(−∞, 1100), [1300, +∞)	before 1100 and after 1300
* {{Year in Europe/expr|{{{1}}}|{{{Code|♦}}}|name=Name}}	(−∞, +∞)	always

By design, each interval includes the left endpoint and excludes the right endpoint. A country with the coding from the first example would therefore be listed if the input year is 1100, but not if the input year is 1300.

Limits

This template uses two {{#ifexist}} parser functions for each included country. Because {{#ifexist}} is an expensive parser function, only 500 of these may be used on a given page (see Wikipedia:Template limits). Depending on the number of countries in the given year, this template can therefore be transcluded only a few times on the same page, and if a page already uses a lot of expensive parser functions, adding it may cause the page to be automatically added to Category:Pages with too many expensive parser function calls.
