The PTP External Tools Framework (formerly known as the Performance Tools Framework) aims to decrease the amount of "Eclipse plumbing" that must be done to integrate existing external tools (Performance Tools and other dynamic tools) in Eclipse, and provide pieces and parts to provide new tools within Eclipse.
The ETFw core provides easy integration of launching existing (e.g. command-line) tools from Eclipse. With just an XML file, an existing app can be launched, with Eclipse UI generated to solicit arguments from the user, launch the tool, and launch any analysis of the results.
For more information, see the External Tools Framework page on the PTP wiki.
The PTP External Tools Framework - Feedback view is a framework for providing an Eclipse view to expose information related to source code (or other files) and provide convenient display and mapping to lines in the source code (or other) files.
Feedback view overview and sample
The ETFw is part of the Parallel Tools Platform (PTP).
