I tried to send a quick example that wouldn't rely on SLIME behavior and I didn't checked properly what I was doing. You're right sbcl behaves as it should in that case. It seems in fact to be a problem with SLIME. It seems someone has already sent an email about this problem: http://common-lisp.net/pipermail/slime-devel/2007-November/006761.html == little part of message == I start SBCL by M-m M-x slime SLIME does start up, I get a lisp prompt and it seems to behave normally. However, the connection between SBCL and SLIME is rather shaky. At some point during working with SBCL, I lose the function parameter info, I also can't break running code then. == end of part of message == If I load the test file (code above) within slime and I do: M-x slime M-x slime-compile-and-load-file When I enter in the debugger, the "v" command for any of my own stack frame, it prints: #<SB-DI::COMPILED-DEBUG-FUN TEST> has no debug-block information. or #<SB-DI::COMPILED-DEBUG-FUN TEST> has no debug-block information. However, if I compile back and load (slime-compile-and-load-file) the file, without having specified the action to take for the debugger (Debugger is still active), then I can see that the same messages are displayed for 1/10 of a second, but then "Evaluation aborted" is printed. I'm using slime-2.0, but slime-cvs (took around the 2007-12-10) does the same thing.

[slime-devel] Cygwin - Emacs 22 - SBCL - swank-loader.lisp does not exist

Ok, I slimmed my slime init things down to exactly what is in the SLIME README: ;;; SLIME (add-to-list 'load-path "~/mydocs/dl/slime/slime/") (setq inferior-lisp-program "sbcl") (require 'slime) (slime-setup) And I have the CVS version of SLIME.

[slime-devel] Filename translator example in manual
by Abhishek Reddy 11 Dec '07

11 Dec '07

Hi, In subsection 8.1.3 of the manual, the example code for slime-create-filename-translator contains a misleading error. It uses :machine-instance "remote.example.com" and :remote-host "remote", whereas the those values should be swapped. There's also a typo ("transaltions") in the relevant text before the example code.

[slime-devel] win32 SLIME : long time and huge buffer to generate 100, 000 data items
by Terrence Brannon 04 Dec '07

04 Dec '07

I'm wondering if there is some way to tell SLIME to not try to report all output from the inferior lisp? My emacs buffer-menu shows the slime-repl as huge and ever-growing: * *slime-repl sbc: 123816001 REPL I'm building a huge data structure and need some way of SLIME sending the command but turning off output from SBCL. Here is the code that is taking a long time to run: (defvar *datasize* 100000 "size of dataset") (defun gendata () (dotimes (i *datasize*) (let* ( (m (random (1+ i))) (n (random (1+ m))) (text (write (generate 'sentence))) ) (list :text text :m m :n n))) ) (setf *d* (gendata)) -- http://www.aliveandwell.org/ | http://www.SlowChess.com | http://mostholy.wholefoodfarmacy.com

[slime-devel] Swank restart-server Patch
by Alan Caulkins 02 Dec '07

02 Dec '07

I run a long-lived lisp image that I access remotely, and I'd like to be able to update slime dynamically without stopping and restarting the whole image. The catch is that after the re-load, I need to restart the Swank listener thread in case the code for its function has changed. Although the current CVS version of Slime can stop a running Swank server by using kill-nth-thread, it doesn't expose the socket that the thread was listening to. Subsequent threads can't bind to the port number because there is already a socket using it, and without a reference to the socket object, it can't be closed. The attached patch provides this access by defining a new package variable, *listener-sockets*. There are also two new functions: stop-server and restart-server. I'm using SBCL 2.6.18, and I have only tested this code with :spawn style servers, but even though I don't use :fd-handler or :sigio, I have provided code for them if anyone is interested in trying it out. With these changes, an online update to a remote lisp should be possible from the Slime REPL as follows: <cvs update slime> (load ".../swank.asd") (asdf:oos 'asdf:load-op 'swank) (swank:restart-server :port 4005 :style :spawn :dont-close t) <slime-disconnect and restart emacs> This code works well for me, but I'm not very familiar with Slime implementation details, so it would not surprise me if I've missed something important in my patch. I hope it proves useful to others. Thanks, -A -- Linux: The ultimate video game.
