No UI eh?
http://lispm.dyndns.org/symbolics-ui-examples/symbolics-ui-examples.html there's also dozens of others examples floating around the Internet, and there's some modern UI toolkits for CL, but besides CLIM and the commercial ones, they're not used too often, as most Lisp applications nowadays are either written for oneself as
>>11 said, or for one's customers or company(in-house). It's rare for Lisp programmers to write commercial applications that you shrink-wrap and sell, but I've seen one just the other month, it was done using Qt for GUI and everything else was done in CL and build with ECL, it was a fairly tiny and snappy app, but it did not interest me, as I already had something similar made for personal use.
Would I make a fancy GUIs for my Lisp tools? I've considered doing a CLIM-like GUI, or just my own custom interface for one project, but before I even begin to consider that, I have much more complex problems to solve(such as writing compilers) than to have time to write a GUI/IDE for it. Maybe someday when everything is solved, I could spend some time for easier user interaction, but for now, Emacs/SLIME is just enough interaction for me, and if I want, I can easily build a standalone version. Since the tools I make are mostly for myself, and other experienced people like myself, GUIs are just a curious thought for the future, but nowhere near a priority.
