Re: [slime-devel] Emacs command for loading Slime and application

Yes, this is bit more difficult because most of the commands work asynchronously. I changed slime-start-and-load a bit so that it should be usable for your needs. In general If you need commands of this sort, it's usually the easiest to write a small CL function for the job, so that Emacs can make a single RPC and doesn't need so much synchronization. > PS: Another problem is that executing (slime) apparently sets back some > variables, e.g. *READ-DEFAULT-FLOAT-FORMAT* which I have set to > DOUBLE-FLOAT when loading Femlisp. Why is that? Can't help you here without more details. Which Lisp are you using? Which communication style? Are threads involved? We don't set *READ-DEFAULT-FLOAT-FORMAT* explicit, but there's always the possibility for bug and that we used WITH-STANDARD-IO-SYNTAX in a wrong place. Helmut.

[slime-devel] Eval defun and compile defun failing on long functions
by Dan Pierson 28 Sep '04

28 Sep '04

Using a version of cmucl similar to 19a slime dies with the following in the *inferior lisp* buffer: ;; Connection to Emacs lost. ;; [Error in function LISP::ASSERT-ERROR: Short read: length=5467 pos=4093] Which looks rather like a packet lenth error of some sort -- 4093 seems suspicious to me. Does anyone have any ideas on how to look into this further? Dan Pierson

[slime-devel] (no subject)
by Pascal J.Bourguignon 28 Sep '04

28 Sep '04

In a Macintosh Programmer Workshop window: echo Hello Command-RETURN inserts: Hello in the window at the current position. In a Smalltalk Workspace window: 1 + 2 . A-d inserts 3 in the Workspace window at the current position. In an emacs lisp source buffer: (insert "\nHello\n") C-u C-x C-e inserts: Hello nil in the current buffer at the point. In a Common-Lisp source buffer with ilisp: (format t "~&Hello") C-z C-e inserts: Hello NIL in the current buffer at the point. In a Common-Lisp source buffer with slime: (format t "~&Hello") C-x C-e inserts nothing. Hides the result as soon as I type or move the mouse (like for example try to copy-and-paste it from the mini buffer, and I have to manipulate buffers, to reduce the size of my source, to hide it entirely to show the whole output that has been sent in some other buffer. Why so much hatred? I want both the output and the result of the function to be inserted at the point! How can that be done with slime? -- __Pascal Bourguignon__ http://www.informatimago.com/ Our enemies are innovative and resourceful, and so are we.

[slime-devel] Error: Attempting to change the lambda list of swank-compile-string
by John M. Adams 27 Sep '04

Dear Friends, Using fresh 1.0 cvs with ACL 7.0 beta I observe: ; Fast loading ; /home/jmadams/.slime/fasl/allegro-7.0.beta/swank-backend.fasl ; ... Error: Attempting to change the lambda list of #<STANDARD-GENERIC-FUNCTION SWANK-COMPILE-STRING> to (STRING &KEY BUFFER POSITION DIRECTORY) results in a confict with method #<STANDARD-METHOD SWANK-COMPILE-STRING (T)> Restart actions (select using :continue): 0: Remove this method 1: retry the load of /home/jmadams/.slime/fasl/allegro-7.0.beta/swank-backend.fasl 2: skip loading /home/jmadams/.slime/fasl/allegro-7.0.beta/swank-backend.fasl 3: retry the load of /home/jmadams/w/slime/swank-loader.lisp 4: skip loading /home/jmadams/w/slime/swank-loader.lisp 5: recompile /home/jmadams/w/slime/swank-loader.lisp 6: Return to Top Level (an "abort" restart). 7: Abort entirely from this (lisp) process. I see that others have reported similar problems, but I have seen no confirmed explanation. Has anyone actually got around this problem? I saw a suggestion that this might be caused by inadvertantly mixing different versions of swank.lisp and slime.el but I don't think that is the problem. I also saw that Helmut couldn't reproduce the problem, but I don't know what ACL version was being referred to. Thanks a lot,

I used to use something like these and rather miss them. The problem is that I find ,restart-inferior-lisp too useful to give up and it ignores all of this. Any suggestions for how to fix that?

[slime-devel] Common Lisp Browser
by Rui Patrocínio 27 Sep '04

27 Sep '04

Hello, I've attached an extensible browser that I hope is useful and simple enough. It uses a lazy mechanism to expand the information required, so that it can be used to explore large systems. Currently it permits to explore class hierarchies and some xref information. I've a big hack that permits to see trace output in a tree-like fashion, but it's very ugly and implementation dependent and so it hasn't been included. A small interface in swank.lisp is needed, using the new API to MOP in the swank-backend: (defun class-direct-classes (class-name fn) (let ((class (find-class class-name nil))) (when class (mapcar #'(lambda (x) (symbol-name (class-name x))) (funcall fn class))))) (defslimefun mop (type symbol-name) "Return info about classes using mop. When type is: :subclasses - return the list of subclasses of class. :superclasses - return the list of superclasses of class." (let ((symbol (parse-symbol-or-lose symbol-name *buffer-package*))) (ecase type (:subclasses (class-direct-classes symbol #'swank-mop:class-direct-subclasses)) (:superclasses (class-direct-classes symbol #'swank-mop:class-direct-superclasses))))) Rui Patrocínio

[slime-devel] save SLIME session (and more)
by slime＠pelissero.de 27 Sep '04

27 Sep '04

In SLIME I've been missing the possibility to save my hacking sessions. I turn off my PC every night (my PC's ACPI doesn't work reliably) and the next day I have to spend half an hour to reload everything and figure out what package/system dependency I've screwed up the day before. Educative exercise, but admittedly annoying. The following patch adds this feature. It implements the "save" (or "freeze") shortcut and can interact nicely with Emacs desktop.el. User can type ",save" or click "REPL->Save session" and get a lisp image saved in the ~/.slime directory. To recover a previously saved session just do "M-x slime-recover-session" instead of "M-x slime". If the customisable variable slime-part-of-desktop is true, the saving and recovering is done automatically upon exit/start of Emacs (provided you use desktop.el). It has been tested on SBCL and CMUCL. In CLISP there seem to be some communications problems during the recovery, that I haven't been able to track down. Those are probably due to the fact that CLISP uses a different communication style than CMUCL and SBCL; just a guess. Unfortunately the following patch contains an unrelated modification I wanted to propose to the mailing list some days ago. The message got bounced by the mailing list server (I wasn't subscribed). Just to clarify what is what, my message went more or less like this: > I personally find a bit annoying the fact that the "compiler notes" > window opens up always at half the frame height, even if the list > to display is very short. I'd really appreciate if the window > popped up to a more modest size and expand as necessary (toggling > the tree branches). > > Something like the following patch would keep the window at most half > the frame's height, although starting at much smaller size. > > Index: slime.el > =================================================================== > RCS file: /project/slime/cvsroot/slime/slime.el,v > retrieving revision 1.390 > diff -c -r1.390 slime.el > *** slime.el 13 Aug 2004 21:23:53 -0000 1.390 > --- slime.el 27 Aug 2004 22:59:40 -0000 > *************** > *** 3322,3328 **** > (slime-tree-insert tree "") > (insert "\n"))) > (setq buffer-read-only t) > !

I believe that's referring to the changes Dan made to the SBCL end of things (the sb-introspect module of SBCL, for instance). Martin Simmons and I both have moderately substantial portions of code in SLIME proper: Martin improvements to the Lispworks backend, and me support for jumping to documentation from conditions in the debugger and from the compiler, enhancements to the hyperspec lookup, and so on.
