Template:Yesno

Template documentation[view] [edit] [history] [purge]

This template normalises an input to be a yes/no output.

Usage

The template discerns five possible logical outputs depending on the first parameter (input if you will).

In its simplest usage these will all be either "yes" or "" (blank — nothing no characters).

1. {{yesno|yes}} results in "yes" (also applies to "Yes", "YeS", etc, "Y", "y" and "1")
2. {{yesno|no}} results in "" (also applies to "No", "NO", "nO", "N", "n" and "0")
3. {{yesno}} results in ""
4. {{yesno|¬}} results in ""
5. {{yesno|purplemonkeydishwasher}} result "yes" (also applies to any other value not given above).

Each of these can be over-ridden.

1. {{yesno|yes|yes=bacon}} results in "bacon" (also applies to "Yes", "YeS", etc, "Y", "y" and "1")
2. {{yesno|no|no=ham}} results in "ham": (also applies to "No", "NO", "nO", "N", "n" and "0")
3. {{yesno||blank=eggs}} results in "eggs"
   1. but {{yesno||no=ham}} results in "ham"
   2. and {{yesno||blank=eggs|no=ham}} results in "eggs"
4. {{yesno|¬|¬=sausage}} results in "sausage"
5. {{yesno|purplemonkeydishwasher|def=cup-of-tea}} results in "cup-of-tea" (also applies to any other value not given above).
   1. but {{yesno|purplemonkeydishwasher|yes=bacon}} results in "bacon"
   2. and {{yesno|purplemonkeydishwasher|def=cup-of-tea|yes=bacon}} results in "cup-of-tea"

This may be used (apparently perversely) thus:

• {{yesno|yes|yes=no|no=yes}} results in "no"
• {{yesno|no|yes=no|no=yes}} results in "yes"

This creates a logical inversion.

Full parameter list

Unnamed parameter 1= the input value to be evaluated. The other parameters (all named, all optional), are the return values for their respective logical outcome. When set, each one overrules their default return value.

{{yesno

| yes  =
| no   =
| blank=
| ¬    =
| def  =
}}
