Template:Yesno/doc


 * Description
 * Yesno evaluates any input and produces a normalized yes or no, based on the content of the input and several configurable options. It is not used in article prose, but in coding complex templates.


 * Usage
 * The template distinguishes five different types of input, supplied on the first unnamed parameter:
 * Yes: Case-insensitive forms of,  ,  ,  , and  ; e.g. "yEs"
 * No: Case-insensitive forms of,  ,  ,  , and  ; e.g. "nO"
 * Nothing: When the input is defined but either contains no value or consists of whitespace character only; i.e. "" or " "
 * Negation: When the input is either  or entirely missing; i.e. "¬" or Yesno
 * Anything else: e.g. "Purple monkey dish washer"


 * By default, the template returns "yes" in the first and last case but returns blank in the other cases.


 * Customizing the output
 * Template's default output can be customized with five named parameters, respectively:,  ,  ,   and  . If these parameters are specified, the template response is as follows:
 * Yes: Template returns the contents of, otherwise returns "yes". For example:
 * "y" results in ""
 * "y" results in ""
 * No: Template returns the contents of, otherwise returns blank. For example:
 * "n" results in ""
 * "n" results in ""
 * Nothing: Template returns the contents of, or of   in absence of the former; otherwise, returns blank.
 * "" results in ""
 * "" results in ""
 * "" results in ""
 * Negation: Template returns the contents of, otherwise returns blank. For example:
 * "¬" results in ""
 * Anything else: Template returns the contents of, or of   in absence of the former; otherwise, returns "yes".
 * "purple monkey dish washer" results in ""
 * "purple monkey dish washer" results in ""
 * "purple monkey dish washer" results in ""


 * For the named parameters, use of a blank value is not the same as omitting the parameter. A blank named parameter tells the template that the customized return value is blank. For example:
 * "purple monkey dish washer" results in ""
 * "purple monkey dish washer" results in "" [blank]
