I use Emacs and Make as my IDE (yes, it does call xcode to do the actual compile). There is at least one Ruby and one Javascript compiler you can use.
all:
xcodebuild -activeconfiguration -activetarget -sdk iphonesimulator3.0 -project MyProject.xcodeproj
I may have to back out of the Ruby. I thought I remembered reading about a Ruby project for iPhone apps, but I think I was smoking something that day.Other Links:
