Template:Yesno/doc

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

Usage

The template has five possible outputs depending on the default parameter (input if you will).

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

{{Yesno|yes}} → "yes" (also applies to "Yes", "YeS", etc, "Y", "y" and "1")
{{Yesno|no}} → "" (also applies to "No", "NO", "nO", "N", "n" and "0")
{{Yesno}} → ""
{{Yesno|¬}} → ""
{{Yesno|purplemonkeydishwasher}} → "yes" (also applies to any other value not given above)

Each of these can be over-ridden.

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

This may be used (apparently perversely) thus:

This creates a logical inversion.
