About

Diff module integrates visual diff UI into NetBeans IDE, here is a list of its main features:

• ability to view differences between files in a nice, graphical way
• highlighting of new, deleted and changed lines
• highlighting of changed words if a single line of text has changed - improves readibility
• ability to edit diffed file in-place; if possible, the right diff pane contains a full-featured editor
• easy, one-click merging of changes from left to right document (if editable)

It's part of Versioning support modules.

Extensible Diff API

Since NetBeans 3.4 Diff defines APIs. Various diff providers and visualizers can implement this API. The module implementation defines several providers and visualizers by default.

The list of ongoing API changes is available as a part of API documentation.
