Highlighting modified lines in Eclipse
With Subversive, you can do Team > Show Annotations, and it will annotate the lines with the author and date of the last modification of that line.
- Open the Preferences window
- Search for "diff"
- Select Quick Diff
- Change the "Use this reference source" to a SCM provider (like CVS, SVN or Git)
By default, it compares to the latest version on disk, which, if you've saved the file, is no diff at all. You have to activate the comparison against a SCM repo. I'm not sure what happens if you more than one type of SCM since this is only a single selection.
Right-click on the file > Team > Show annotation.
A brown tape will appear on the left-side of the code (it represents commited lines), and the modified lines will be shown in white.
