I’ve tryed it…Aptana Studio is a great IDE for web development, I used it a lot with PHP…but had a great problem wich lead me to use TextMate instead. Aptana Studio can become very very slow during its startup. It is because it tries to index all your file of all your open projects. I always have more than 10 projects in my Eclipse IDE (on whom Aptana Studio is designed) and the time to wait for Aptana Studio to let me work was awful. I returned to PHPEclipe plugin for Eclipse,Netbeans or TextMate, swiching them just in case of my programming needs. But now I need something for Ruby On Rails. Ok i can use TextMate, but I also want to use RadRails installed above my Eclipse Galileo…but RadRails is now integrated in Aptana Studio! And there seems not to be a link to install it as Eclipse plugin…

So I sayid to myself: “someone should have done this before!” and Google told me : check Satish’s Blog.
He gave me the answer for older Eclipse. Now I want to Integrate his tutorials with the new features for Eclipse Galileo and new urls.

First start your Eclipse IDE. From the Help menu select ‘Install new software…’. It will open a new window for installing remote and local packages. Click on the ‘Add…’ button on the right to add 2 new update sites.

First you should install RDT (Ruby Development Tools). So add the this update site:
Name: RDT
Location: http://update1.aptana.org/rdt/3.2

Uncheck ‘Group items by category’ and Eclipse will show a new package to install (Ruby Development Tools). Select it and then click ‘Next’ to continue the installation and follow the normal installation instruction that will appear on the screen.
Once installed you’ll be asked to restart Eclipse.

Once restarted you should go another time in Help->Install new software… and add a new update site:

Name: RadRails
Location: http://radrails.sourceforge.net/update

Check the ‘RadRails’ package and click ‘Next’. Wait for download and installation to complete…and voilà RadRails is now installed without installing AptanaStudio.
