This post details how to add a Subversion (SVN) plugin to Aptana to allow you to compare OpenLayers code with previous versions.
A straw poll was taken on the OpenLayers mailing list in April 2010, and OpenLayers v3 development is taking place in git, with the central repository stored on GitHub. This means working with SVN and OpenLayers may become redundant. However as many OSGEO projects are stored in SVN with no current plans to move the same plugin and knowledge of working with SVN will still be useful.
For further details on working with SVN there is a free e-book “Version Control with Subversion” available at http://svnbook.red-bean.com/
Installing the Plugin
1. Open the Plugin Manager, by clicking on the green jigsaw piece in the toolbar below.
