Module:FindYDCportal/doc

A helper template to find the most specific chronology portal which actually exists for a given year or decade. Used to simplify linking to a chronology portal.

Takes one parameter, which must be either a year (e.g. "1879", "1123") or a decade (e.g. "1940s", "730s").

If the parameter is missing, empty, or does not fit the required format, an empty string is returned.

Output

If a portal is found, returns its name without the namespace prefix, e.g.

• for "Portal:1980s" return 1980s
• for "Portal:19th century" return 19th century

If no portal is found, it returns an empty string.

Usage

{{#invoke: FindYDCportal | main |YYYY}}
