މޮޑިއުލް:Unsubst/doc

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||$N=TEMPLATENAME |$B=

 [ ... existing template code ... ]

}}

The name of the template must be given as "$N", and the wikitext to display when not substed must be given as "$B".

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.

Example

Consider a template Template:Example containing the following code:

{{ {{{|safesubst:}}}#invoke:Unsubst||$N=Example |foo=bar |date=__DATE__ |$B=

 [ ... Template code goes here ... ]

}}

Original	Result
{{subst:example}}	{{Example|foo=bar|date=ނޮވެމްބަރު 2024}}
{{subst:example|foo=X}}	{{Example|foo=X|date=ނޮވެމްބަރު 2024}}
{{subst:example|baz=X}}	{{Example|foo=bar|baz=X|date=ނޮވެމްބަރު 2024}}
{{subst:example|date=January 2001}}	{{Example|foo=bar|date=January 2001}}
