Abstract
Commit comments written by developers when they submit their changes to a versioning system are useful for a number of tasks: Developers write commit comments to document changes and as a means to communicate with the rest of the development team; Researchers mine commit-related data contained in software repositories to support software evolution and reverse engineering activities. However, the support provided by IDEs is restricted in this respect, as they limit the users to use only text to document their changes.
We present Commit 2.0, an IDE enhancement to enrich commit comments using software visualization. Commit 2.0 generates visualizations of the performed changes at different granularity levels, and lets the user annotate them.
