Greetings. I'm writing a Common Windows (a more advanced version of the Intellicorp standard) implementation for Allegro Common Lisp here at Franz. What I need is a relatively low level interface from Common Lisp to X11. The problem is that I need it soon, within a couple months from now. I don't want the toolkit functionality from Lisp, and I don't need many of the more esoteric X11 Xlib features. I also don't care if the interface is through C foreign code or directly to the X11 server. I would greatly appreciate hearing from people who are working on an interface and have something working or expect to have something working soon. Otherwise I guess I'll have to hack something up myself, which seems like a huge duplication of effort. And now for something completely different. Are bitmapped displays really going to be useful in the future? Imagine a bitmapped display with, oh, say 4000 by 3000 pixels in color. That comes out to something like 12Meg of memory, assuming each pixel has an 8-bit color value. Is this reasonable? More importantly is there any hardware that is capable of passing this much bandwith 60 or even 30 times per second? How about a 10000x8000 display? (Assuming some non-crt technology becomes cheap enough to make such a thing possible) (Then again, I guess you also get to assume you have superconductive busses, eh? :-) -- John Irwin (jdi@ucbvax.berkeley.edu) JOhn jdi@ingres.Berkeley.EDU

Bob Scheifler &co have built just such an interface.
It will be in the XV11R1 distribution.
