Lightweight IDE

Hi /prog/!

I'm a GNU/Linux programmer with an insane love for command line interfaces, although I'd like to find out a beautiful IDE, possibly working under GTK.

What do you suggest?

plan 9 and inferno both have ed. solaris has ed. all bsd systems have ed. minix has ed.
there isnt' a single modern operating system that doesn't have ed.
the same cannot be said of sam, vi, or any substandard editor such as vim or emacs.
