テンプレート:Ifnotempty1
Documentation
This is a version of Template:Ifnotempty with the condition-string equal to the then-part. In this case using this separate template is especially useful if the expansion of the condition-string/then-part gives a large preprocessor node count, as it avoids doubling this amount.
Spaces and newlines are ignored for the condition, but preserved in the result.
Usage
{{ifnotempty1| p | q }}
gives " p "{{ifnotempty1| | q }}
gives " q "
