Subclipse - marking code changes like in NetBeans

If you are referring to the Viewing Changes in the Source Editor section of subversion in Netbeans:

Then it should be like activating the Quick diff Annotate in Subclipse:

Team -> Show Annotations option on a file

Subclipse automatically keeps track the changes that you do in Eclipse.

If you would like to see the changes, the convention in Eclipse is to go to Team -> Synchronize menu on the project.

In Window -> Preferences navigate to General -> Editors -> Text Editors -> Quick Diff and tick "Enable quick diff", "Show differences in overview ruler" and set "Use this reference source" to "Pristine SVN Copy".

You might also want to change the colors to match NetBeans (blue for Changes, green for Additions, red for Deletions).

Note that you'll probably need to restart Eclipse for this to take effect.

As you go on changing the code it will show your changes on the side ruler until you commit to SVN.
