##language:en == Actions == Actions are tools that work on a page or the whole wiki, but unlike macros do not add ''to'' the page content when viewing a page, but work ''on'' that page content. They either produce some output based on page contents (navigational actions like searching) or implement functions that are not related to viewing a page (like deleting or renaming a page). There is a set of system-defined actions, which includes page editing; you can extend the set of known actions by your own ones. See HelpForDevelopers for more on that. The following actions are added to the list of user-defined extension actions at the bottom of each page. This happens to any mixed-case extension, for other actions (all lower-case) see the list further down this page. Some of these action might not be available for your wiki site. * `AttachFile`: attach files to a page, see /AttachFile for more details. * `DeletePage`: Delete a page, after you confirmed it; deletion means a final backup copy is created and only then the page is deleted, i.e. you can ''revive'' the page later on (as long as the backups are not physically deleted). * `RenamePage`: Rename a page, after you confirmed it. * `LikePages`: list pages whose title starts or ends with the same MeatBall:WikiWord as the current page title. * `LocalSiteMap`: show nearby links of the current page, i.e. list all referred-to pages, and in turn their references, to a certain limited depth. * `SpellCheck`: call the spell checker for the current page; see HelpOnSpellCheck for more. The following is a list of ''internal'' actions that are used to implement the various icons and links at the top and bottom of pages, or supplement certain macros. * titleindex: Implements the listing of all page names as text or (Self:?action=titleindex) or XML (Self:?action=titleindex&mimetype=text/xml); the main use of this action is to enable MeatBall:MetaWiki. * fullsearch: this action is triggered by clicking on the "Go" button of the `FullSearch` macro (Self:?action=fullsearch&value=HelpOnActions). * titlesearch: this action is triggered by clicking on the "Go" button of the `TitleSearch` macro (Self:?action=titlesearch&value=HelpOnActions). * inlinesearch: this implements the inline search for the form fields at the bottom of each page (note that this uses POST requests, so you won't normally see this action in URLs). * highlight: highlight the search word when you click on a link in a search result list. * diff: display differences between page revisions. * info: show meta-data on a page. * recall: display an older revision of a page. * show: display a page (the default action). * refresh: refresh the cached version of a page (currently only used on XSLT-formatted pages). * print: show the print-view of a page, which omits the navigational items from the display view. * edit: edit this page. * savepage: save this page (do not ever use this manually). * subscribe: subscribe to a page. * userform: save user preferences. * bookmark: set bookmark for RecentChanges. * raw: send the raw wiki markup as text/plain (e.g. for backup purposes via wget); Self:SystemInfo?action=raw shows the markup of SystemInfo. * format: emit specially formatted views of a page. * rss_rc: generate a RSS feed of RecentChanges. * chart: display charts. * export: export the wiki content. ''[experimental]'' * content: for transclusion into static web pages, this action emits the pure page content, without any , , or tags. * links: generates a list of all pages and the links on them, just like MeatBall:LinkDatabase. * xmlrpc: Wiki XML-RPC interface, see MeatBall:XmlRpcToWiki. * revert: revert to an older version of the page. * macro: execute a helper action in an external macro.
