Usage[edit]
Meta template that returns "yes" if evaluated during substitution, and the empty string if evaluated during transclusion.
Note that this template must be used in safesubst mode to work properly:
{{ {{{|safesubst:}}}issubst}}
Examples[edit]
- "
{{issubst}}
" → "" - "
{{subst:issubst}}
" → "yes"
