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.
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
If no portal is found, it returns an empty string.
Usage
- Year parameter
((FindYDCportal|YYYY)) ... where YYYY is a 3- or 4-digit year
- Decade parameter
((FindYDCportal|YYY0s)) ... where YYY0s is a 3- or 4-digit decade
Examples
- Years
((FindYDCportal|2018))→ 2010s((FindYDCportal|1982))→ 1980s((FindYDCportal|1946))→((FindYDCportal|1857))→((FindYDCportal|736))→((FindYDCportal|1800))→
- Decades
((FindYDCportal|2000s))→((FindYDCportal|1940s))→((FindYDCportal|560s))→
- Missing parameter
((FindYDCportal))→
- Empty parameter
((FindYDCportal|))→
- Invalid parameter
((FindYDCportal|1927-related))→((FindYDCportal|Swedish chef))→
Logic
If the parameter is a year:
- If the year portal exists, return its name.
Otherwise try the decade. - If the decade portal exists, return its name.
Otherwise try the century - If the century portal exists, return its name.
Otherwise return an empty string
If the parameter is a decade:
- If the decade portal exists, return its name.
Otherwise try the century - If the century portal exists, return its name.
Otherwise return an empty string
