{{#ifeq:{{ROOTPAGENAME}}|Yesno|{{high-use|10125977|all-pages = yes}}}}
{{tlx|Yesno}} (or {{tlx|YesNo}}) evaluates any input and produces a normalized <samp>yes</samp> or <samp>no</samp>, 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>, and <code>1</code>; e.g. {{tlx|Yesno|yEs}}
# '''No''': Case-insensitive forms of <code>No</code>, <code>n</code>, <code>false</code>, and <code>0</code>; e.g. {{tlx|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| }}
# '''Negation''': When the input is either <code>¬</code> or entirely missing; i.e. {{tlx|Yesno|¬}} or {{tlx|Yesno}}
# '''Anything else''': e.g. {{tlx|Yesno|Purple monkey dish washer}}
By default, the template returns "yes" in the first and last case but returns blank in the other cases.
Two short-hand templates for the most common uses that override the default behavior:
* {{tlx|yesno-yes}} or {{tlx|YesNo-Yes}} – 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 {{tlx|YesNo-No}} – 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".
===Customizing the output===
Template's default output can be customized with five named parameters, respectively: {{para|yes}}, {{para|no}}, {{para|blank}}, {{para|¬}} and {{para|def}}. If these parameters are specified, the template response is as follows:
# '''Yes''': Template returns the contents of {{para|yes}}, otherwise returns "yes". For example:
#* {{tlx|yesno|y|3=yes=Yeah}} results in "{{yesno|y|yes=Yeah}}"
#* {{tlx|yesno|y|3=yes=bacon}} results in "{{yesno|y|yes=bacon}}"
# '''No''': Template returns the contents of {{para|no}}, otherwise returns blank. For example:
#* {{tlx|yesno|n|3=no=Nay}} results in "{{yesno|n|no=Nay}}"
#* {{tlx|yesno|n|3=no=ham}} results in "{{yesno|n|no=ham}}"
# '''Nothing''': Template returns the contents of {{para|blank}}, or of {{para|no}} in absence of the former; otherwise, returns blank.
#* {{tlx|yesno||3=blank=eggs}} results in "{{yesno||blank=eggs}}"
#* {{tlx|yesno||3=no=ham}} results in "{{yesno||no=ham}}"
#* {{tlx|yesno||3=blank=eggs|4=no=ham}} results in "{{yesno||blank=eggs|no=ham}}"
# '''Negation''': Template returns the contents of {{para|¬}}, otherwise returns blank. For example:
#* {{tlx|yesno|¬|3=¬=sausage}} results in "{{yesno|¬|¬=sausage}}"
# '''Anything else''': Template returns the contents of {{para|def}}, or of {{para|yes}} in absence of the former; otherwise, returns "yes".
#* {{tlx|yesno|purple monkey dish washer|3=def=cup of tea}} results in "{{yesno|purple monkey dish washer|def=cup of tea}}"
#* {{tlx|yesno|purple monkey dish washer|3=yes=bacon}} results in "{{yesno|purple monkey dish washer|yes=bacon}}"
#* {{tlx|yesno|purple monkey dish washer|3=def=cup of tea|4=yes=bacon}} results in "{{yesno|purple monkey dish washer|def=cup of tea|yes=bacon}}"
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:
* {{tlx|yesno|purple monkey dish washer}} results in "{{yesno|purple monkey dish washer}}"
* {{tlx|yesno|purple monkey dish washer|3=def=}} results in "{{yesno|purple monkey dish washer|def=}}" {{var|[blank]}}

{{#ifeq:{{ROOTPAGENAME}}|Yesno|{{high-use|10125977|all-pages = yes}}}}
{{tlx|Yesno}} (or {{tlx|YesNo}}) evaluates any input and produces a normalized <samp>yes</samp> or <samp>no</samp>, 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>, and <code>1</code>; e.g. {{tlx|Yesno|yEs}}
# '''No''': Case-insensitive forms of <code>No</code>, <code>n</code>, <code>false</code>, and <code>0</code>; e.g. {{tlx|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| }}
# '''Negation''': When the input is either <code>¬</code> or entirely missing; i.e. {{tlx|Yesno|¬}} or {{tlx|Yesno}}
# '''Anything else''': e.g. {{tlx|Yesno|Purple monkey dish washer}}
By default, the template returns "yes" in the first and last case but returns blank in the other cases.
Two short-hand templates for the most common uses that override the default behavior:
* {{tlx|yesno-yes}} or {{tlx|YesNo-Yes}} – 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 {{tlx|YesNo-No}} – 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".
===Customizing the output===
Template's default output can be customized with five named parameters, respectively: {{para|yes}}, {{para|no}}, {{para|blank}}, {{para|¬}} and {{para|def}}. If these parameters are specified, the template response is as follows:
# '''Yes''': Template returns the contents of {{para|yes}}, otherwise returns "yes". For example:
#* {{tlx|yesno|y|3=yes=Yeah}} results in "{{yesno|y|yes=Yeah}}"
#* {{tlx|yesno|y|3=yes=bacon}} results in "{{yesno|y|yes=bacon}}"
# '''No''': Template returns the contents of {{para|no}}, otherwise returns blank. For example:
#* {{tlx|yesno|n|3=no=Nay}} results in "{{yesno|n|no=Nay}}"
#* {{tlx|yesno|n|3=no=ham}} results in "{{yesno|n|no=ham}}"
# '''Nothing''': Template returns the contents of {{para|blank}}, or of {{para|no}} in absence of the former; otherwise, returns blank.
#* {{tlx|yesno||3=blank=eggs}} results in "{{yesno||blank=eggs}}"
#* {{tlx|yesno||3=no=ham}} results in "{{yesno||no=ham}}"
#* {{tlx|yesno||3=blank=eggs|4=no=ham}} results in "{{yesno||blank=eggs|no=ham}}"
# '''Negation''': Template returns the contents of {{para|¬}}, otherwise returns blank. For example:
#* {{tlx|yesno|¬|3=¬=sausage}} results in "{{yesno|¬|¬=sausage}}"
# '''Anything else''': Template returns the contents of {{para|def}}, or of {{para|yes}} in absence of the former; otherwise, returns "yes".
#* {{tlx|yesno|purple monkey dish washer|3=def=cup of tea}} results in "{{yesno|purple monkey dish washer|def=cup of tea}}"
#* {{tlx|yesno|purple monkey dish washer|3=yes=bacon}} results in "{{yesno|purple monkey dish washer|yes=bacon}}"
#* {{tlx|yesno|purple monkey dish washer|3=def=cup of tea|4=yes=bacon}} results in "{{yesno|purple monkey dish washer|def=cup of tea|yes=bacon}}"
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:
* {{tlx|yesno|purple monkey dish washer}} results in "{{yesno|purple monkey dish washer}}"
* {{tlx|yesno|purple monkey dish washer|3=def=}} results in "{{yesno|purple monkey dish washer|def=}}" {{var|[blank]}}
