Returns the test value prefixed and suffixed with appropriate values dependant upon whether test value matches.

Usage

{{ If is | Test | Value | Then prefix | Then suffix | Else prefix | Else suffix }}

where (unnamed parameters, in sequence) represent

	Test		→		something to be compared to Value (parameter # 2).
	Value		→		something to compare Test (parameter # 1) to.
	Then prefix		→		[optional], if Test = Value, returned added to the beginning of Test.
	Then suffix		→		[optional], if Test = Value, returned added to the end of Test.
	Else prefix		→		[optional] returned added to the beginning of Test if Test does not match Value.
	Else suffix		→		[optional] returned added to the end of Test if Test does not match Value.

Example

{{ If is | 1 | 0 | Then Prefix← | →Then Suffix | Else Prefix← | →Else Suffix }}

yields
  Else Prefix←1→Else Suffix

{{ If is | 1 | 1 | Then Prefix← | →Then Suffix | Else Prefix← | →Else Suffix }}

yields
  Then Prefix←1→Then Suffix

{{ If is | 1 | 0 |  |  | Else Prefix← | →Else Suffix }}

yields
  Else Prefix←1→Else Suffix

{{ If is | 1 | 1 |  |  | Else Prefix← | →Else Suffix }}

yields
  1

{{ If is | 1 | 0 | Then Prefix← | →Then Suffix |  |  }}

yields
  1

{{ If is | 1 | 1 | Then Prefix← | →Then Suffix |  |  }}

yields
  Then Prefix←1→Then Suffix

{{ If is | City, Prov | , |  |  | {{Open squares}} | {{Close squares}} }}

yields

  City, Prov

{{ If is | City, Prov | , |  |  | <nowiki>[[</nowiki> | <nowiki>]]</nowiki> }}

yields

  [[City, Prov]]

{{ If is | 1 | 0 | Then Prefix← | →Then Suffix }}

yields
  1

{{ If is | 1 | 1 | Then Prefix← | →Then Suffix }}

yields
  Then Prefix←1→Then Suffix

• {{If is}} returns prefixed/suffixed test value; prefix/suffix depend of whether test value matches.
  
• {{If found}} returns prefixed/suffixed test value if test exists; alternately uses different prefixing/suffixing or returns a different value if test does not exist.
