I am happy to announce the addition of a very nice web editor to shellx called Aptana Studio 3. It requires a visual connection of some sort, NX, OpenNX, x2go, or VNC, or alternately, if you have X-windows on your machine and are connected via ssh, you can launch from the command line.
If you have a visual desktop up, you can go to Applications->Programming->Aptana Studio 3, or alternately from the shell launch as “aptana”.
Either way, this is a graphical application so either you need to launch from a graphical desktop or redirect the DISPLAY to an X-server on your machine via ssh X tunneling.
It colorizes matching elements and makes editing very easy.
