{{tlx|Yesno}} (or {{tlg|YesNo|nolink=on|code=on}}) evaluates any input and produces a normalized <samp>yes</samp> 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:
# '''Yes''': Case-insensitive forms of <code>Yes</code>, <code>y</code>, <code>true</code>, <code>on</code>, and <code>1</code>; e.g. {{tlx|Yesno|yEs}} &rarr;  {{Yesno|yEs}}
# '''No''': Case-insensitive forms of <code>No</code>, <code>n</code>, <code>false</code>, <code>off</code>, and <code>0</code>; e.g. {{tlx|Yesno|nO}} &rarr; {{Yesno|nO}}
# '''Nothing''': When the input is defined but either contains no value or consists of [[whitespace character]] only; i.e. <code><nowiki>{{Yesno|}}</nowiki></code> or {{tlx|Yesno|&nbsp;}} &rarr; {{Yesno|}}
# '''Negation''': When the input is either <code>¬</code> ([[alt code]] [https://www.rapidtables.com/code/text/alt-codes.html 170]) or entirely missing; i.e. {{tlx|Yesno|¬}} or {{tlx|Yesno}} &rarr; {{Yesno|¬}} 
# '''Anything else''': e.g. {{tlx|Yesno|Purple monkey dish washer}} &rarr; {{Yesno|Purple monkey dish washer}}

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:
* {{tlx|yesno-yes}} or {{tlg|YesNo-Yes|nolink=on|code=on}} – always returns "yes" (or the specified replacement result in {{para|yes}}) unless an explicit negative value is given; i.e., it evaluates to "yes" even when the value is empty or missing.
* {{tlx|yesno-no}} or {{tlg|YesNo-No|nolink=on|code=on}} – always returns "no" (or the specified replacement result in {{para|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".
