{{Yesno}} (or {{YesNo}}) evaluates any input and produces a normalized yes or nil output, based on the content of the input and several configurable options. It is not used in article prose, but in coding complex templates.
Usage
аредакциазураThe template distinguishes five different types of input, supplied on the first unnamed parameter:
- Yes: Case-insensitive forms of
Yes,y,true,on, and1; e.g.{{Yesno|yEs}}→ ааи - No: Case-insensitive forms of
No,n,false,off, and0; e.g.{{Yesno|nO}}→ - Nothing: When the input is defined but either contains no value or consists of whitespace character only; i.e.
{{Yesno|}}or{{Yesno| }}→ - Negation: When the input is either
¬(alt code 170) or entirely missing; i.e.{{Yesno|¬}}or{{Yesno}}→ - Anything else: e.g.
{{Yesno|Purple monkey dish washer}}→ ааи
By default, the template returns "yes" in the first and last case but returns nil (blank, empty string) in the other cases.
Two short-hand templates for the most common uses that override the default behavior:
{{yesno-yes}}or{{YesNo-Yes}}– always returns "yes" (or the specified replacement result in|yes=) unless an explicit negative value is given; i.e., it evaluates to "yes" even when the value is empty or missing.{{yesno-no}}or{{YesNo-No}}– always returns "no" (or the specified replacement result in|no=) unless an explicit positive value is given; i.e., it evaluates to "no" even when the value is present, as long as it does not contain anything that resolves to "yes".
