It kind of bothered me that there was no IDE functionality for emacs, so I wrote a rather crude ASDF system browser for Emacs. Here's the code: http://tehran.lain.pl/stuff/asdf-browser.el
To use it, simply bind #'asdf-browser to a key.
If you find it useful, please post some feature requests or send diffs. Have fun!
Hi! Thanks for system browser. I also wrote simple patch for slime to facilitate working with asdf. Now you can type M-. and see (ASDF:DEFSYSTEM SOMESYSTEM) among other stuff. You can select it and go to the definition of the system in somesystem.asd. Just download swank.lisp.patch from http://pastebin.com/f7c24c808, copy it to your slime directory and $ patch -i swank.lisp.patch I hope this will be usefull.
