সাঁচ:Ifnotempty

Documentation

With this template #if can be used in a way such that it does not strip spaces and newlines from the "then" and "else" part. For evaluating the condition spaces and newlines are stripped like with ParserFunctions.

Usage

{{ifnotempty|x| p | q }} gives " p "
{{ifnotempty|| p | q }} gives " q "

Compare:

{{#if:x| p | q }} gives "p"

Note that, unlike parser functions, templates require writing equals signs in values of unnamed parameters as {{=}}

For full substitution, simply use সাঁচ:Cnw or সাঁচ:Cnw. If the condition contains a parser function, template, or variable, that should be substituted too. Optionally the "then" or "else" part can also be substituted.

Internal technical details

For evaluating the condition the template uses the actual parser function; however, not directly with p and q, because this strips spaces and newlines from the result, but with index values 1 and 2. The result can be 1, 2. The template with the applicable name is called (Template:P1 or Template:P2), with as parameters p and q.

Conditions
