Module:If preview/configuration: Difference between revisions

Module documentation[view] [edit] [history] [purge]

This module does the actual work for determining if the page is in preview mode. It is a separate module so mw.loadData can only run it once per page, rather than once per use.

The above documentation is transcluded from Module:If preview/configuration/doc. (edit | history)
Editors can experiment in this module's sandbox (create | mirror) and testcases (create) pages.

	-- I don't know why we're checking for nil but hey, maybe someday things
	-- would have broken
	return revision_id == nil or revision_id == ''
