Is anybody currently maintaining a definitive list of IDE's that work with the Raspberry Pi? If not, can anyone supply a list of general-purpose IDE's (such as Aptana Studio 3), and language specific IDE's (think of IDLE) for the Pi?
While Vim by itself is a standalone text-editor(powerful one at that), it can support the features of an IDE. If I needed an IDE-like environment, this is the route that I would go simply because Vim is my favorite editor(for good reasons).
Xojo does not run on the Pi, but it can create apps for Raspberry Pi (and Windows, OS X, Linux, web and iOS).
I haven't tested it yet, but there's also Code::Blocks IDE on the Pi Store.
In addition to Lazarus you may also install and run Free Pascal on its own on Raspbian. It has a nice text-mode IDE. See http://www.elinux.org/Free_Pascal_on_RPi for details.
