Ask YC: What is your favorite IDE?

I use NetBeans for RoR. Its pretty good, though I switch intermittently to emacs (I am still trying to learn emacs).

I would not say its my favorite IDE. I would prefer to work in emacs all the time (soon, fingers crossed).

I have a feeling this has been asked before, but I'll bite: vim

emacs, but it isn't really an IDE

I've used IntelliJ a few times as well. There is a lot that that it does that could be implemented on top of emacs. Had there been an attempt to build a 3G/4G ide on top of emacs (Intelligent completion, "quick fix", generating Makefile/Makefile.PL/build.xml)?

As I do Java, Groovy and Ruby, I find IntelliJ perfect for all three.

TextMate for Ruby, NetBeans for Java.

I like Wing IDE for python.

emacs.

vim+bash=I win!

vim.
