Modifying Default Diff Settings

Default settings for the behavior of the Diff engine and the appearance of diffed documents and folders are on the Engine and Presentation pages, respectively, of the Options dialog box. The Engine page, shown here, has settings that determine the conditions under which Stylus Studio runs the diff automatically, which items in a document (comments and text, for example) you want the diff engine to ignore, and settings that allow you to choose diffing algorithm tunings optimized for change description or time, for example.

Settings on the Engine page are reflected in the Diff editor tool bar, and in the XML Diff menu, shown here.
