Helper module to facilitate a substituted template transform into a template transclusion.

Maintenance templates, such as {{Citation needed}} or {{Refimprove}}, should never be substituted. A trick to avoid that is to make a template substitute to its transcluded form.

Usage

To turn a template into a self-substituting template, wrap the existing template code with:

{{ {{{|safesubst:}}}#invoke:Unsubst||$B=
}}

The wikitext to display when not substed must be given as "$B". A parameter "$N" may also be seen in some templates; this was required in an older version of the module, but is no longer necessary and may be removed.

All other parameters passed to the #invoke will be copied to the generated template invocation as default values. If the value of any of these default parameters is "__DATE__", that value in the generated template invocation will be the current month and year.

Some templates have a <noinclude> but no matching </noinclude> at the end of the template. In such cases the missing </noinclude> must be added before the ending }}.

Example

Consider a template Template:Example containing the following code:

{{ {{{|safesubst:}}}#invoke:Unsubst||foo=bar |date=__DATE__ |$B=
}}
Original Result
{{subst:example}} {{Example|foo=bar|date=January 2025}}
{{subst:example|foo=X}} {{Example|foo=X|date=January 2025}}
{{subst:example|baz=X}} {{Example|foo=bar|baz=X|date=January 2025}}
{{subst:example|date=January 2001}} {{Example|foo=bar|date=January 2001}}
