[slime-devel] Comment indentation in newer Emacsen
by Edi Weitz 03 Jul '05

03 Jul '05

Dumb question number two for today: I've recently switched to a CVS build (circa end of January) of GNU Emacs on Windows. Now, if I have a function like this in a lisp mode buffer (defun foo () "This is a very very very very very very very very very very very very long comment line." (bar x)) and press M-q within the comment string the result looks like so: (defun foo () "This is a very very very very very very very very very very very very long comment line." (bar x)) However, in 21.3 the result looked like this (defun foo () "This is a very very very very very very very very very very very very long comment line." (bar x)) which is what I prefer. Is this a bug or can the behaviour be changed with some setting that I'm missing? Thanks, Edi.

[slime-devel] sbcl threads
by Gábor Melis 01 Jul '05

01 Jul '05

Recently sbcl switched to using pthreads if it is built with thread support. Sbcl cvs head has a thread-os-thread-slot instead of thread-pid-slot. Its value is a pid in non-threaded builds, and a pthread_t otherwise. Now, pthread_t is an unsigned long on linux/nptl and the high bits are really used so communication with emacs breaks down: the id of the startup thread on my system does not fit into an elisp integer: 1098623904 => 24882080 The patch below adds a mising a thread state and works with os-thread instead of pid. However, the (unsigned-byte 32) communication problem is still there.

[slime-devel] Maxima+Slime?
by C Y 01 Jul '05

01 Jul '05

Has anybody here tried working with Maxima in Slime? I have managed to figure out how to load it (start slime with sbcl, load maxima-build.lisp, then do (maxima-load) to load the fasl files) and typing (run) will start Maxima OK, but then when I tried to do load("./file.mac"); I got some kind of error (don't have exact error on this machine, but can be provided.) Has anybody tried working with Maxima inside SLIME? I am definitely interested in this based on limited experience working without it, but I don't know how much of an ordeal it might be. Any help or experience appreciated, and thanks much for SLIME. CY __________________________________ Yahoo! Mail Stay connected, organized, and protected.

[slime-devel] which version of slime with which version of sbcl?
by frederic.gobry＠epfl.ch 30 Jun '05

30 Jun '05

Hi, I'm a new lisper, and I'm trying to use sbcl and slime together, on Debian (sbcl-0.9.1.41-1 from unstable). I tried slime-1.2.1 which gave strange errors (I don't have them at hand but can reproduce them if you wish), and switched to the CVS version. Now I can connect to the sbcl process, evaluate a few expressions from the REPL, but as soon as I do C-c C-c from a lisp file, I get this error: Unable to display error condition: The value #S(SB-C::DEBUG-SOURCE :FROM :FILE :NAME "/tmp/fileCdgZoa" :CREATED 3329044824 :COMPILED 3329044824 :SOURCE-ROOT 0 :START-POSITIONS #(0) :FUNCTION NIL :PLIST NIL) is not of type SEQUENCE.

Do you have an idea of what's going on? Thanks in advance, Frédéric

[slime-devel] Summer of Code, mentorship, technical adviser
by Heow Eide-Goodman 29 Jun '05

29 Jun '05

Guys, Google has decided to fund the development of a Slime stepper! Woohoo! We have a capable student but our mentors aren't experienced with slime-internals. If anyone is willing to step forward for either a mentorship or technical advisor role, we'd be happy to work with you on this exciting project. Thanks, - Heow

[slime-devel] Slime hanging on foreign function calls with Lispworks
by Shawn Nicholson 29 Jun '05

29 Jun '05

Hello, I am a new user to slime and have run into something I can't seem to figure out. I am running Lispworks 4.4.5 Professional and Slime 2005-4-27 (LispWorks Port 1525 PID 220). I am attempting to run some code which calls some foreign functions however any attempt to do so causes Slime to hang. The windows click does not happen at all. Any ideas on what I'm missing (or what settings I have incorrect) that would prevent me from making FLI calls? Thanks, Shawn (in-package :cl-user) (defparameter *segman-dll* "C:\\Projects\\SegMan\\hemets\\src\\segman.dll") (fli:register-module *segman-dll*) (fli:define-foreign-function (c_single_click "c_single_click" :source) ((pause :int)) :result-type :void) (defun single-click (&optional (pause 0)) (format t "Executing single click.~%") (c_single_click pause)) (defun test-click () (single-click))

[slime-devel] swank-sbcl fails on FreeBSD
by Julian Stecklina 29 Jun '05

29 Jun '05

Hello, swank-sbcl.lisp refers to the alien "linux_no_threads_p" which does not exist on my SBCL 0.8.17 (yeah, someone should probably update the ports :-/) on FreeBSD. The following patch fixes avoids this: Regards, -- Julian Stecklina "We were not out to win over the Lisp programmers; we were after the C++ programmers. We managed to drag a lot of them about halfway to Lisp." - Guy Steele, Java spec co-author

[slime-devel] C-c C-c of a function referencing a large constant takes a long time to compile
by David Steuber 29 Jun '05

29 Jun '05

Hello slime-devel, This evening I discovered a nasty annoyance with Slime and OpenMCL when doing C-c C-c to compile a function. The function makes reference to a 46x46x46x46 constant array of integers (defined with DEFCONSTANT). Any such function that refers to the array takes over a minute to compile with C-c C-c. If I have openmcl running in a terminal, the same function will recompile instantly. Here are a few bits of relevant code and *slime-events*: (DEFCONSTANT +LETTER-FREQUENCY-HYPERCUBE+ #4A((((6384784 ... (defun start-decoder (cipher-text pos) (let (m1 (pf 0)) (dotimes (a +modulo+) (dotimes (b +modulo+) (dotimes (c +modulo+) (dotimes (d +modulo+) (let ((sp (aref +letter-frequency-hypercube+ a b c d))) (when (< 0 sp) (let* ((w (modadd a (aref cipher-text pos))) (x (modadd b (aref cipher-text (+ 1 pos)))) (y (modadd c (aref cipher-text (+ 2 pos)))) (z (modadd d (aref cipher-text (+ 3 pos)))) (pfp (* sp (aref +letter-frequency-hypercube+ w x y z)))) (when (< pf pfp) (setf m1 (list a b c d) pf pfp))))))))) m1)) (:emacs-rex (swank:compile-string-for-emacs "(defun start-decoder (cipher-text pos)\n (let (m1 (pf 0))\n (dotimes (a +modulo+)\n (dotimes (b +modulo+)\n (dotimes (c +modulo+)\n (dotimes (d +modulo+)\n (let ((sp (aref +letter-frequency-hypercube+ a b c d)))\n (when (< 0 sp)\n (let* ((w (modadd a (aref cipher-text pos)))\n (x (modadd b (aref cipher-text (+ 1 pos))))\n (y (modadd c (aref cipher-text (+ 2 pos))))\n (z (modadd d (aref cipher-text (+ 3 pos))))\n (pfp (* sp (aref +letter-frequency-hypercube+ w x y z))))\n (when (< pf pfp)\n (setf m1 (list a b c d)\n pf pfp)))))))))\n m1))\n" "two-time-pad.lisp" 5674 "/Users/david/usr/src/ITA Software Puzzles/Two-Time Pad/") nil t 540) (:return (:ok ("T" "65.65")) 540) I'm running SLIME 2005-06-21, OpenMCL 0.14.3-050610a, and Carbon Emacs from CVS on 2005-06-12, OS X 10.3.9, GCC 3.3 from Xcode 1.5.
