I tried cells on clisp and it didn't work 'out of the box'. Firstly, the two .asd files are missing clisp in the list of supported platforms. Secondly, my clisp (compiled with all defaults) choked on the copywrite © symbol, maybe it should be changed to the more traditional (C) for the sake of portability. I'm using current-cells.zip dated 8th Nov. -- jan

[cells-devel] Cells-ref documentation
by Kenny Tilton 29 Nov '03

29 Nov '03

After a couple of days off I took a look at the cells-ref doc I just uploaded. Looks awful. Some humongous typos in there, my apologies. I will revise cells-ref in light of any feedback, otherwise I think a tutorial document is in order, probably in the form of heavily-commented Lisp source so it can be included in the build process so I'll be more likely to keep it current with changes to Cells. kt -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

[cells-devel] cells-ref (incredibly rough draft)
by Kenny Tilton 26 Nov '03

26 Nov '03

I just uploaded cells-ref.pdf and cells-ref.html (as generated by FrameMaker from the same .fm original) to the FTP site, in a new subdirectory dedicated to documentation: ftp://common-lisp.net/pub/project/cells/doc You'll see it is pretty much all over the map, and it needs an index and lots more examples, but I have been poking at it long enough and at this point would benefit from a round of requests for enhancment, so there it is. I'd rather be working on a port of Cello to an X environment, but will continue producing doc if anyone wants it. Ongoing doc effort could be to refine these, or document the vital Family class, or document by example by producing fun sample code illustrating typical Cells code or... talk to me, I'm all ears. kt -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

If perchance there is some quick way to confirm that is working (an included test C stub lib?), you can eliminate that variable moving forward. Then... ...repeat using UFFI as your FFI. Now UFFI is utterly devoid of callback support precisely because folks like CMU did not support callbacks, but do as I did with win32 CLs: get callbacks working by extending UFFI with stuff that works for CMU. Use FFI wherever possible. I will post tomorrow (when I am not exhausted) a zip of my stuff, so you can just add some #+cmu features to my callback extensions to UFFI. At this point FG works, CMU callbacks work, CMU+UFFI works with callbacks...time to CMU+UFFI+FG. What that will entail is building my UFFI bindings to opengl (hopefully not a problem) and then getting maybe a hundred lines of CL (Lesson 14 of Nehe) to work.

[cells-devel] Can someone help Rui? Re: lisp + glut
by Kenny Tilton 17 Nov '03

17 Nov '03

Rui, One of the gents on this list did one of the CMUCL hacks to permit callbacks into CMUCL from C. Perhaps he can steer you in the right direction. Also, he always tells me the CMUCL mailing list is the place to learn about new development. Do you follow that? I wish I could be more help, but I have flirted with CMUCL only briefly, and then with a standard release. All that said, I do want to port my Cello GUI (CL+Cells+Freeglut) to an X-based Freeglut fairly soon, and someone else here volunteered to assist. Maybe we should all hunker down and at least get CMUCL+Freeglut working. Then Cello just falls into place. Step one would be to do nothing but get Freeglut built on Linux, tested out with one of the "C" demos that comes with it. FG just had a major release and support there is very prompt. I built FG2 without a problem on win32, but got sidetracked before I could build the C demos. Step 2 is driving FG2 and OpenGL from CL. I have somewhere a Lisp implementation of exercise 14 from the NeHe OpenGL site. That does not involve my Cells library, so it could be a good test case. I'll make sure it still works on FG2 on win32 first. That would get Rui going, and then it would be easy for me to bring up Cello. Who's down for any of this? I want to get /something/ out in the way of a Cells reference before doing any coding, and I am also doing stuff (with Cello!) for a Lisp+music group here in NYC, so it will be a few days before I can get involved, but then I think I will fire up my Linux box and see what I can see. ps. If anyone is absolutely dying for the reference, I can send a horrific work in progress out at any time by email. kenny Rui Patrocínio wrote: >On Mon, 2003-11-17 at 18:38, Kenny Tilton wrote: > > >>Rui Patrocínio wrote: >> >> >> >>>hi there, >>> >>>I've seen some posts from you regarding lisp + glut in c.l.l.

[cells-devel] FG2 + CL + Win32 OK
by Kenny Tilton 17 Nov '03

17 Nov '03

1. Yes, FG2 has a couple of C demos. I built those under win32 and they ran ok, tho I had to move the fractals.dat file. The "one" demo is the classic teapot running in game mode (full-screen). That works, too. 2. I found and ran my Nehe lesson 14 against FG2. The idle and display callbacks work, but not the keyboard or wmClose. Anyway, that's enough to make me the rest should fall into place OK with a little hammering. I gotta break now to see if I can whip up something for the music+lisp guys for tomorrow night, then I'll hunker down on the Cells reference and Cello/win32 and then Cello/x. kt -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

[cells-devel] reference rising
by Kenny Tilton 14 Nov '03

14 Nov '03

Just so you know, a rough outline has been built. I am going to sashay thru the code this AM to see if I left anything out, then I will fill it in as fast and loose as I can and put it up on FTP. If anyone has looked at Cells and/or any of its doc and wants to throw requests/suggestions over the wall, now is the time. kenny -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

[cells-devel] A shocking proposal
by Kenny Tilton 13 Nov '03

13 Nov '03

First let me emphasize I have not even confirmed the feasibility of this proposal, and that step one will be to confirm said feasibility. That said, having done this three times atop different window manager models, I have great confidence it can be done. So: What if I base the Cells tutorials on the free LW downloads? If I can believe what I hear, it is portable across Mac OS X, Linux, and some other system called Window or something. :) That will be a lot more fun than text-based tutorials like 01-cell-basics.lisp. Oh, speaking of which, did you all also find Bill Clementson's Cells write-up?: http://home.comcast.net/~bc19191/2003_09_07_bill-clementson_archive.html Not that I mean to send you on a scavenger hunt for Cells documentation, but if you are left with questions those will help me figure out what to explain first and in better detail. kenny -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application
