Template:FindYDCportal
This template uses Lua: |
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.
It is a wrapper template around Module:FindYDCportal. For use within templates, it is most efficient to invoke the module directly. For one-off use, the template requires less typing and makes the code easier to read.
Contents
Parameters
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.
