Template:Yesno/doc

{{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

The template distinguishes five different types of input, supplied on the first unnamed parameter:

1. Yes: Case-insensitive forms of Yes, y, true, on, and 1; e.g. {{Yesno|yEs}} → yes
2. No: Case-insensitive forms of No, n, false, off, and 0; e.g. {{Yesno|nO}} →
3. Nothing: When the input is defined but either contains no value or consists of whitespace character only; i.e. {{Yesno|}} or {{Yesno| }} →
4. Negation: When the input is either ¬ (alt code 170) or entirely missing; i.e. {{Yesno|¬}} or {{Yesno}} →
5. Anything else: e.g. {{Yesno|Purple monkey dish washer}} → yes

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".

Customizing the output

Template's default output can be customized with five named parameters, respectively: |yes=, |no=, |blank=, |¬= and |def=. If these parameters are specified, the template response is as follows:

1. Yes: Template returns the contents of |yes=, otherwise returns "yes". For example:
   • {{yesno|y|yes=Yeah}} results in "Yeah"
   • {{yesno|y|yes=bacon}} results in "bacon"
2. No: Template returns the contents of |no=, otherwise returns blank. For example:
   • {{yesno|n|no=Nay}} results in "Nay"
   • {{yesno|n|no=ham}} results in "ham"
3. Nothing: Template returns the contents of |blank=, or of |no= in absence of the former; otherwise, returns blank.
   • {{yesno|blank=eggs}} results in "eggs"
   • {{yesno|no=ham}} results in "ham"
   • {{yesno|blank=eggs|no=ham}} results in "eggs"
4. Negation: Template returns the contents of |¬=, otherwise returns blank. For example:
   • {{yesno|¬|¬=sausage}} results in "sausage"
5. Anything else: Template returns the contents of |def=, or of |yes= in absence of the former; otherwise, returns "yes".
   • {{yesno|purple monkey dish washer|def=cup of tea}} results in "cup of tea"
   • {{yesno|purple monkey dish washer|yes=bacon}} results in "bacon"
   • {{yesno|purple monkey dish washer|def=cup of tea|yes=bacon}} results in "cup of tea"

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:

• {{yesno|purple monkey dish washer}} results in "yes"
• {{yesno|purple monkey dish washer|def=}} results in "" [blank]

Logical distinctions

Input parameter 1 ( Usage Wraps a short span of text in <syntaxhighlight> tags (see mw:Extension:SyntaxHighlight). This template should be used for short samples; longer content should use <pre>...</pre> or <syntaxhighlight>...</syntaxhighlight>. See Help:Wiki markup for an explanation of what the various tags do. If the content includes an equals sign (=), you must specify the parameter explicitly: {{code|1=date=30 Feb 2010}}. The template uses the <syntaxhighlight> tag with the attribute inline=1. This works like the combination of the <code> and <nowiki> tags, applied to the expanded wikitext. For example, {{code|some '''wiki''' text}} will not render the word "wiki" in bold, and will render the tripled-single-quotes: However, {{code|a {{template}} call}} will still invoke the template: Use <nowiki>...</nowiki> around the template name to avoid this problem: When used inline with regular text, {{code}} generally looks best and is easiest to read when it is explicitly spaced apart from the regular text: is well spaced: foo    quux. versus: which is going to be visually confusing for many: foo quux. because "foo" and "" will seem more closely associated than "" and ""; the width of the space character in a monospaced font is almost always larger than in a proportional font. Use parameter {{{2}}} (unnamed, as |2=, or more explicitly as |lang=) to specify a language for mw:Extension:SyntaxHighlight. This option defaults to plain-text, i.e. no highlighting. There is no highlighting option for wikitext as a markup language, though and are valid values, as are , , , , and many others. Attempting to use an invalid one causes a list of valid ones to be displayed in place of the template output, when the page is previewed or saved. This template does not need to be substituted. Examples Markup Renders as Included templates Embedded templates do not function as expected inside {{code}}; for longer, free-form blocks of code, which can contain templates such as {{var}} and {{samp}}, use <code>...</code> as a wrapper instead of this template.
