MediaWiki version: = 1.8

Returns revisions for a given page, or the latest revision for each of several pages. When using parameters marked as (enum), titles= must have only one title listed. The code for this query is located on the git repository at ApiQueryRevisions.php

Revisions: Parameters[edit | edit source]

  • rvprop: Which properties to get for each revision
    • ids: Get both of these IDs: revid, parentid (default) MW 1.11+
    • flags: Whether the revision was a minor edit (default)
    • timestamp: The date and time the revision was made (default)
    • user: The user who made the revision, as well as userhidden and anon flags (default)
    • userid: User id of revision creator, as well as userhidden and anon flags
    • sha1: SHA-1 (base 16) of the revision

    • parsedcomment: The edit/log comment in HTML format with wikilinks and section references expanded into hyperlinks (MW 1.16. Added in r61761)
    • size: The size of the revision text in bytes
    • content: The revision content. If set, the maximum limit will be 10 times as low
    • tags: any tags for this revision, such as those added by AbuseFilter. MW 1.16+
  • rvcontinue: When more results are available, use this to continue. This can be used, for example, for fetching the text of all revisions of a page (although an XML export might be more efficient).
  • rvlimit: The maximum number of revisions to return. Use the string "max" to return all revisions (subject to being broken up as usual, using continue). Limited by query limits defined in ApiBase, which equals 500 for users and 5000 for bots. (enum)
  • rvstartid: Revision ID to start listing from. (enum)
  • rvendid: Revision ID to stop listing at. (enum)
  • rvstart: Timestamp to start listing from. (enum)
  • rvend: Timestamp to end listing at. (enum)
  • rvdir: Direction to list in. (enum)
    • older: List newest revisions first (default) NOTE: rvstart/rvstartid has to be higher than rvend/rvendid
    • newer: List oldest revisions first NOTE: rvstart/rvstartid has to be lower than rvend/rvendid
  • rvuser: Only list revisions made by this user
  • rvexcludeuser: Do not list revisions made by this user
  • rvexpandtemplates: Expand templates in rvprop=content output
  • rvgeneratexml: Generate XML parse tree for revision content
  • rvparse: Parse revision content. For performance reasons if this option is used, rvlimit is enforced to 1.
  • rvsection: If rvprop=content is set, only retrieve the contents of this section. This is an integer, not a string title. MW 1.13+
  • rvtoken: Tokens to get for each revision
  • rvdiffto: Revision ID to diff each revision to. Use "prev", "next" and "cur" for the previous, next and current revision respectively.
  • rvdifftotext: Text to diff each revision to. Only diffs a limited number of revisions. Overrides diffto. If rvsection is set, only that section will be diffed against this text.
