Template:Diff/doc

This is a documentation subpage for Template:Diff. It may contain usage information, categories and other content that is not part of the original template page.

This template is useful for creating links to "diffs"; that is, links to pages that show the differences between two versions of a wiki page.

Every historical version of a page has a revision ID, which you can find from the history of the page. Given a page name and one or two revision IDs, you can construct links to several types of diffs.

{{ diff | page | diff | oldid | label }}

• page – The title of the page.
• diff – The ID or keyword that is used against the base ID. Possible keywords are:

  cur – compare with the current version of a page.

  prev – compare with the previous version of a page.

  next – compare with the next version of a page.

• oldid – The base ID onto which the diff is generated.
• label – Text to display as link. No label will give a numbered link.

All parameters are optional. Omitted parameters must be empty (by using a double pipe). You can also use the named variables page=, diff=, oldid= and label=

• {{Oldid}} – simplifies the case for linking to a known old version
• {{Diff2}} – same as {{Diff}}, but assumes a diff between the given revision and the one immediately before
• {{Diff3}} – same as {{Diff2}}, but does not support section links
• {{Diff4}}
• {{URL to diff}} – takes a diff URL and makes a {{Diff}} template
• {{Diffsandbox}} – compares a given page with the sandbox version
• {{DiffPages}} – accepts two pagenames (no id's needed)
• {{Querylink}} – generic template to construct query strings
• diff utility – syntax highlight on wiki pages with mw:Extension:SyntaxHighlight GeSHi
• Special:Diff serves a similar purpose; see Help:Wiki markup#Linking to old revisions of pages, diffs, and specific history pages.
• {{TextDiff}}
• {{Url to title}}
