[slime-devel] slime-apropos-package now sorts correctly
by Hoehle, Joerg-Cyril 20 Apr '07

20 Apr '07

Hi, slime-apropos-package now conforms to its specification and also sorts symbols printed with package prefix. I supply the patches as attachments in the hope that MS-Windows nor MS-Outlook will break the TAB and LF characters of the original diff. I hope this is fine. Regards, Jörg Höhle.

for those of you who don't follow c.l.l (which is probaly a good idea) i commited William Bland's patch[1]. see the ChangeLog for details. 1 - http://groups.google.com/group/comp.lang.lisp/browse_thread/thread/e1d0b7bf… -- -Marco Ring the bells that still can ring.

[slime-devel] [patch] closing connections with :fd-handler style
by Stephen Compall 15 Mar '06

15 Mar '06

As far as I can tell, the only way a Swank connection object with style :fd-handler will ever be closed due to EOF (with close-connection) is if either the fd-handler implementation detects the EOF state and knows how to destroy Swank connections, or a condition is raised in the dynamic context of with-reader-error-handler. Looking at the topmost form in that context, however, it can only happen if (listen socket) answers T, so that the attempt to read can proceed and raise an eof-error, which gets wrapped up, etc. I modified process-available-input to test (listen socket) only after calling FN at least once; after all, it always returns T when the handler is called for a normal input state. Without this patch, my fd-handler backend gets into an endless loop calling the handler in install-fd-handler (with the :eof state); with this patch, the socket is closed, removed from *connections*, and from the fd-handler backend properly. Attached is the patch. -- Stephen Compall http://scompall.nocandysoftware.com/blog

[slime-devel] comma shortcut doesn't work always
by Edi Weitz 31 Jan '06

31 Jan '06

Another minor glitch that I encountered is that the comma shortcut in the REPL doesn't always work. I can consistently reproduce it (GNU Emacs 21.3.50 and also 21.3 release) like this: 1. Make sure point is at the beginning of a REPL input line. 2. Split Emacs frame into two windows, one of them being the REPL the other one containing something else. 3. Hide REPL window with C-x 0. 4. Now type M-x slime. 5. Type the comma. At this point I'm not asked for a shortcut command in the minibuffer but the comma is simply entered into the REPL instead. Anybody else seeing this? Cheers, Edi.

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

[slime-devel] Installing slime for clisp 2.35 - Error
by Surendra Singhi 10 Jan '06

10 Jan '06

Hello, I recently upgraded to clisp 2.35 and now when I try to start slime on a lisp file, slime gets stuck. The *inferior-lisp* buffer shows me the following restart. ** - Continuable Error INTERN("*DOCUMENTATION*"): #<PACKAGE SYSTEM> is locked If you continue (by typing 'continue'): Ignore the lock and proceed The following restarts are also available: SKIP :R1 skip (COMPILE-FILES-IF-NEEDED-SERIALLY #) STOP :R2 stop loading file C:\Program Files\XEmacs\xemacs-packages\lisp\slime-1.2.1\swank-loader.lisp ABORT :R3 ABORT Doing 'continue', doesn't starts the slime repl, nor does selecting any of the restarts help. But, the inferior lisp buffer shows a lisp prompt, which can be used. What should I do to get over this problem? The slime related contents of my init file are: (load-library "inf-lisp") (setq inferior-lisp-program "C:\\clisp-2.35\\clisp.exe -I -m 256mb") (add-hook 'inferior-lisp-mode-hook (lambda () (inferior-slime-mode t))) (require 'timer) (require 'slime) (slime-setup) Thanks. -- Surendra Singhi http://www.public.asu.edu/~sksinghi/index.html "All animals are equal, but some animals are more equal than others." - Orwell, Animal Farm, 1945

[slime-devel] Connection broken (sbcl 0.9.7 & slime-cvs)

Hi, I'm new to lis[t,p] :) I'm looking for help with slime/sbcl. Slime says: Lisp connection closed unexpectedly; * ;; Connection to Emacs lost. ;; [ debugger invoked on a SIMPLE-ERROR in thread #<THREAD "control-thread" {9B9D269}>: #<SB-SYS:FD-STREAM for "a constant string" {9A593C9}> is closed. debugger invoked on a SIMPLE-ERROR in thread #<THREAD "auto-flush-thread" {9B92CA1}>: #<SB-SYS:FD-STREAM for "a constant string" {9A593C9}> is closed. when i try to compile and load my lisp examples file (see attachments).

[slime-devel] Coding systems: suggested change to slime-open-stream-to-lisp
by Harald Hanche-Olsen 31 Dec '05

31 Dec '05

May I suggest the following patch to slime-open-stream-to-lisp: --- slime.el 30 Dec 2005 19:26:22 +0100 1.574 +++ slime.el 30 Dec 2005 22:58:49 +0100 @@ -2775,9 +2775,8 @@ (list* '("<" . slime-mark-presentation-start-handler) '(">" . slime-mark-presentation-end-handler) bridge-handlers))) - (set-process-coding-system stream - slime-net-coding-system - slime-net-coding-system) + (let ((pcs (process-coding-system (slime-current-connection)))) + (set-process-coding-system stream (car pcs) (cdr pcs))) (when-let (secret (slime-secret)) (slime-net-send secret stream)) stream)) It appears to solve the following problem. I have not changed slime-net-coding-system from its default value, but I have (setf slime-lisp-implementations '((sbcl ("sbcl") :coding-system utf-8-unix) (cmucl ("cmucl") :coding-system iso-latin-1-unix))) So when I run sbcl, coding systems on the emacs and sbcl sides match for input and printing of values, but there is a mismatch on printing from lisp code: The sbcl side uses utf-8, while the emacs side assumes latin-1. Quick demo (first good, second bad): cl-user> #\å #\å cl-user> (format t "~C" #\å) Ã¥ nil - Harald

[slime-devel] Re: Putting REPL prompt on the mode line?

My gut feeling is that putting more distance between the expression and the package it was run in is not a win for me. Plus you'd have to put point on it to determine it that way which is quite inconvenient. > Do you want to see that kind of prompt in an editor buffer or let the > editor take care of it? In a normal Lisp buffer I agree - its primary purpose is editing the file, and interaction with the Lisp is secondary. Having a buffer-package shown on the mode-line works well in that case. However, I think the REPL buffer is a different story - interaction is primary there, so I think the prompt works well (for me). > I'm going a step further and changing the way the package and evaluation > state are shown. It's purely for appearance. Would a REPL buffer be nicer > if the left margins of all lines of input and output were aligned? IMHO, no. I like having the input indented by the prompt because it helps delimit what exactly is input without relying on font faces. Please experiment, though. Just make the end product be a customize option and everyone will be happy. :-) -bcd
