Usage
[edit]Normal usage
[edit]{{Terrorist incidents in countryname in YYYY category header}}
The normal usage requires no parameters, because the template looks up the other data.
e.g. on Category:Terrorist incidents in the United States in 1954, no parameters are needed
The other needed data is:
- the adjectival form of the country in which the country is located. This is looked up by Template:GetAdjectiveFromCountryName
- the continent(s) in which the country is located. This is looked up by Template:Country2continent
If either of those lookups fails, then an error is reported unless the required data is supplied by an optional parameter.
That may be due to this category being misnamed, or it may be due to an omission in the lookup table used by Template:GetAdjectiveFromCountryName or Template:Country2continent. (Some former countries may have been omitted. Also, when country has been renamed, the lookup uses only the current country name).
If a lookup fails, then the template creates no output other than an error message. If you are satisfied that the category is correctly named, use the one of the optional parameters below.
Optional parameters
[edit]|nationality=Fooishbypasses the lookup of the nationality, and uses "Fooish"|continent1=Atlantisbypasses the lookup of the continent, and uses "Atlantis".|continent2=Lemuriabypasses the lookup of the continent, and adds a second continent: "Lemuria"|parentcountry=AnotherCountryis available for use when a country is part of another country.
e.g. on Category:Terrorist incidents in England in 2011, use{{Terrorist incidents in countryname in YYYY category header|parentcountry=United Kingdom}}|diagnose=yesturns on diagnostics, which may help if the template doesn't work as expected
