I found a message in the *inferior-lisp* buffer ("event-history end") saying that iso-8859-1 was used. However, the buffer's mode line says "u". Same for the slime-repl and *slime-events* buffers. Same for many other buffers in Emacs (e.g. Dired), while Lisp source buffers mostly say "--", i.e. ASCII. .slime-history.eld says -*- utf-8-unix (but so far there's only ASCII therein). This is Emacs-21.4 on a Ubuntu Breezy i386 with the default clisp-2.35 (not self compiled) -- with #+UNICODE. How comes? Is that 1/3 a bug-report? >because the packet length field isn't interpreted >correctly and the payload of the packet will be truncated I wasn't aware slime is sending packets. I thought it's all Lisp data, readable with READ :) I think it's then ok to modify the patch to assert :iso-8859-1 on a non unicode clisp. And let the user figure out how to set this???

CLISP still breaks for me in the latest CVS. I have had a look at all of the DEFSLIMEFUN's that were modified since 4/18 (the previous CVS version that I had which was working ok with CLISP) and haven't found any obvious clues. Any suggestions on how I might debug this issue as it occurs at startup during the slime-connect processing in Emacs (after CLISP has started up successfully)? - Bill

Return from the frame can evaluate an expression which might or might not refer to user code. Actually it is very usefull to call the original function with different parameters for example. In which case the environment problem still exists. Of course if one is aware of that then the issue can be safely avoided. levy ________________________________________________________________ Elégedetlen helyzetével? Új kihívásokra vágyik?

If we now restart BAR, the dynamic binding for *A* that FOO > established will still be visibile, and it'll print 1 instead. On the other hand return from frame is already supported for SBCL in SLIME. And if I got it right the above statement also means that return from frame works the same "somewhat bad" way. I mean returning from the frame of bar (in the debugger) the value of *a* will return 1 instead of 0.

[slime-devel] clisp without unicode patch
by Hoehle, Joerg-Cyril 19 Jan '06

19 Jan '06

Hi, I thought about alternatives and rejected them. Probably this patch is just fine as is and it should not raise an error when Emacs uses UTF-8 or anything and clisp was only built with 8bit strings --without-unicode. 2006-01-14 Joerg Hoehle <hoehle(a)users.sourceforge.net> * swank-clisp (find-encoding): work in a 8bit clisp w/o #-UNICODE. --- swank-clisp.lisp.orig 2005-11-12 00:43:43.000000000 +0100 +++ swank-clisp.lisp 2006-01-14 13:17:08.000000000 +0100 @@ -122,7 +122,9 @@ (:iso-latin-1-unix "iso-8859-1") (:utf-8-unix "utf-8") (:euc-jp-unix "euc-jp")))) - (ext:make-encoding :charset charset :line-terminator :unix))) + (ext:make-encoding :charset (if (member :unicode *features*) + charset :default) + :line-terminator :unix))) (defimplementation accept-connection (socket &key (external-format :iso-latin-1-unix) The idea in the present patch is that (untested) the same set of slime.fas files might possibly work in both builds of clisp: with and without unicode. But you'd need to compile from the 8bit version. Regards, Jorg Hohle.

Re: [slime-devel] [patch] Make it possible to keep FASL files in source directory
by Nathan Bird 19 Jan '06

19 Jan '06

This makes swank no longer asdf loadable. E.g. http://paste.lisp.org/display/15792 The problem is that UCW depends upon swank, but just stating that dependency in the asd is no longer good enough. All the swank packages aren't there until the load-swank function is called, and since files in UCW reference the swank package we get a reader error. The name "SWANK-BACKEND" does not designate any package. Can we please make swank continue to be fully loaded by default? Maybe make several ASD files, one similar to the current swank.asd that just makes swank-loader available, and another that also loads a file that does (swank-loader:load-swank) ? Any thoughts?

[slime-devel] How to cleanly update from CVS
by Jonathon McKitrick 19 Jan '06

19 Jan '06

Hi all, I was bitten earlier this week when I updated and found that swank no longer started and required changed to .sbclrc to fix. Is there a recommended procedure to follow when I cvs up to make sure an update goes cleanly? -Jonathon -- "I am sure that Jesus would use a command prompt. Hello? Ten Commandments??"

[slime-devel] How should I test multithreaded SBCL code using SLIME?
by Glenn Ehrlich 18 Jan '06

18 Jan '06

All, I'm experimenting moving over a body of code from LispWorks to SBCL and I've got some multithreaded code. When using LW, I'd just start up a LW core image on a command line, manually start up swank, then do slime-connect a couple of times, and use the 2 repls to experiment / debug the multithreaded code. Specifically, I've got a shared queue that waits when empty; I'd call the dequeue in repl 1, see that it properly waits, then enqueue in repl 2 and ideally see the enqueue return in repl 1; crude, but simple. I try doing the same thing in SBCL. I start up SBCL in a shell, start up swank, and I can start up the 1st repl with slime-connect. When I attempt a 2nd slime-connect, emacs loses the connection to SBCL and I get this in the shell running SBCL: WRITE: (:return (:ok (:pid 6102 :style :spawn :lisp-implementation (:type "SBCL" :name "sbcl" :version "0.9.8") :machine (:instance "localhost.localdomain" :type "X86" :version "Intel(R) Pentium(R) 4 CPU 2.80GHz") :features (:acl-compat :cl-ppcre it.bese.arnesi.mopp::have-mop :split-sequence :asdf :sb-thread :ansi-cl :common-lisp :sbcl :unix :sb-doc :sb-test :sb-package-locks :sb-unicode :sb-source-locations :ieee-floating-point :x86 :elf :linux :gencgc :stack-grows-downward-not-upward :c-stack-is-control-stack :stack-allocatable-closures :linkage-table :os-provides-dlopen :os-provides-dladdr :os-provides-putwc) :package (:name "COMMON-LISP-USER" :prompt "CL-USER"))) 1) WRITE: (:open-dedicated-output-stream 32783) READ: "(:emacs-rex (swank:connection-info) \"COMMON-LISP-USER\" :repl-thread 1) " DISPATCHING: (:EMACS-REX (SWANK:CONNECTION-INFO) "COMMON-LISP-USER" :REPL-THREAD 1) ;; Event history end. ;; Connection to Emacs lost.

I've got a function for starting up swank: (defun start-swank (&key (port swank::default-server-port) (style swank:*communication-style*) (dont-close t)) "Start the SLIME swank server, listening on PORT. Multiple connections are allowed." (swank:create-server :port port :style style :dont-close dont-close)) and I call it with default arguments, (start-swank). Is it possible to drive SBCL like I mentioned at the top with LispWorks and if so, how do I do it? Thanks! Glenn Ehrlich

[slime-devel] [patch] Make it possible to keep FASL files in source directory
by Maciek Pasternacki 18 Jan '06

18 Jan '06

Hello. I use SLIME with SBCL; I have two instances of SBCL in my system (sometimes more); one is system-wide installation, second is project-local, both are of the same version, but with possibly different features. Both use SLIME (project-local version loads swank by hand). Problem is that system-wide SBCL is threaded, and project-local one is not; thus, .fasl files generated by one are unreadable to other. I don't want project-local SBCL and SLIME to mess with my system-wide settings and I'd prefer to have it leave any files outside project dir alone. I made a small patch against current CVS to swank to make it possible to keep FASL files in source directory; now it is turned on by pushing :SWANK-FASL-IN-PLACE to *FEATURES*; I couldn't think of better way of signalling swank-loader.lisp that we want to have FASL with sources before loading it (i.e. before (DEFPACKAGE)s and (DEFVAR)s). If this way is ok, please apply this patch; I don't insist on this particular way of communicationg with loader (it seems kludgy), if there is better one, please treat this post as yet another feature request. -- __ Maciek Pasternacki <maciekp(a)japhy.fnord.org> [ http://japhy.fnord.org/ ] `| _ |_\ / { ...I choose to live and to grow, take and give and to ,|{-}|}| }\/ move, learn and love and to be paranoid and to lie, hate and fear \/ |____/ and to do what it takes to move through.. } ( M.

[slime-devel] Beginning of defun should work for compile defun?
by Liam M. Healy 17 Jan '06

17 Jan '06

If I do C-M-a to go to beginning of defun, then do C-c C-c to compile the defun, it compiles the previous defun. Shouldn't the "beginning of defun" be the current defun? See also discussion: http://meme.b9.com/cview.html?channel=lisp&start=3346261896 Liam
