Module: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:

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. Such templates are automatically placed in.

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 but no matching at the end of the template. In such cases the missing must be added before the ending.

Example
Consider a template Template:Example containing the following code:
