Extension:RevisionSlider

The RevisionSlider extension adds a slider interface to the diff view, so that you can easily move between revisions.

Opt-out
If you are not using the RevisionSlider at all and also don't want to see the collapsed RevisionSlider bar at the top of the diff page, you can opt-out by checking Don't show the RevisionSlider in you preferences under Appearance -> Diffs.

JavaScript Hooks
The RevisionSlider uses AJAX to reload the diff page when new revisions are selected. Once the page has been reloaded both the wikipage.content and wikipage.diff hooks are fired. If user JavaScript or extension JavaScript acts on the diff page you may need to listen to these hooks.

API calls & fetching data
Unless expanded, the tool is not doing any API calls. Only when the user expands the slider, it fetches data about revisions (revision-id, timestamp, user, comment, size and flags). The tool only fetches data for revisions that are currently visible on the screen (maximum 500 revisions) and data about additional revisions is only loaded when the user navigates back or forth on the timeline using the arrows.

Background
The RevisionSlider is a feature to fulfill one of the top wishes of the German Community wishlist and is developed by WMDE's TCB team. It is inspired by DerHexer's revisionjumper gadget and based on a prototype by the WMF Community Tech team.
