[slime-devel] Why is slime breaking READ-SEQUENCE in cmucl ?
by Håkon Alstadheim 09 Mar '04

09 Mar '04

swank-cmucl.lisp contains code which makes cmucl break w.r.t. the ansi cl standard; in that it makes READ-SEQUENCE insist on filling its target buffer. The hyperspec says, in 21.2 under READ-SEQUENCE: If the end of file for stream is reached before copying all elements of the subsequence, then the extra elements near the end of sequence are not updated. swank-cmucl installs its own READ-INTO-SIMPLE-STRING which calls SYSTEM:READ-N-BYTES with the EOF-ERRORP argument true. In addition to being wrong, it does not solve the problem I believe it is trying to solve. At the end of this mail is a patch to remove the buggy version of READ-INTO-SIMPLE-STRING. If this is trying to protect against truncated reads, I believe the solution is to run a loop (possibly with a timeout) until the needed bytes have been read from the socket. If I am mistaken, then the assertion that is already there should suffice, making SYSTEM:READ-N-BYTES throw an error gives us nothing extra.

[slime-devel] Native Win32 XEmacs w/ cygwin CLisp
by 49gu4n502＠sneakemail.com 08 Mar '04

08 Mar '04

Background: I'm just starting out with SLIME, and it's been just a little bit rough because of my environment, but more promising than ILisp. The complications are: I'm running on WinXP, I've generally used a native version of XEmacs (21.4.13 as of today), I use some Cygwin tools, and since I'm just getting reacquainted with Lisp, I've been trying out various implementations. I tried out Cygwin XEmacs over the last week, but found it less stable overall than the native version, so I've reverted. I did get SLIME going with Cygwin XEmacs and Cygwin CLisp (latest version), no problem. When I switched back to native XEmacs, I had problems with SLIME initialization. XEmacs is sending native file namestrings to CLisp, and the latter chokes on the backslashes. After only a little searching, I found slime-translate-to-lisp-filename-function, and now I define it as follows during XEmacs initialization: (defvar slime-translate-to-lisp-filename-function (function (lambda (s) (replace-in-string s "\\\\" "/")))) However, I have found and fixed two places in slime.el that weren't calling this function. These two changes allow me to get to REPL. The functions that I changed are slime-maybe-start-lisp and slime-start-swank-server. Here's output from cvs diff: diff -r1.228 slime.el 968c968 < (concat slime-path slime-backend))) --- > (slime-to-lisp-filename (concat slime-path sli me-backend)))) 980c980 < (slime-swank-port-file)))) --- > (slime-to-lisp-filename (slime-swank-port-file)) ))) (If there's a better format I can use for showing changes, please tell me how to get it.) Nice code, by the way, it only took a little guesswork to find the hook for translating file names. Very different from my ILisp experience.

[slime-devel] [PATCH] Help for sldb
by Jouni K Seppanen 07 Mar '04

07 Mar '04

Hi, While I was learning how to use sldb I found myself thinking that it could use some help features. Here are some rudimentary docstrings so that C-h m and C-h k work, and a function (bound to ?) that displays some possible keystrokes, similar to the corresponding function in dired. -- Jouni K Seppänen

[slime-devel] swank:frame-locals
by Marco Baringer 06 Mar '04

06 Mar '04

i would like to make a change to slime which isn't directly related to slime as an emacs lisp IDE but related to slime's (unexpected) use as a generic debugger interface. The function frame-locals currently returns the name and the value of a frame-local as strings, while this is great for emacs it makes it impossible for me[1] to usefully inspect those values in my debugging interface (built on slime but doesn't use emacs). The change i would like to propose is the make swank:frame-locals return, along with :value-string and :name, a :value and :name-value property. is this ok or is it important that slime remain concentrated on being an emacs interface and not a general common lisp implementation abstraction layer? This particular change would be rather trivial but I can see this being the start of a road slime may not want to take. [1] - i'm pretty sure i'm not the only person using slime without emacs, but i can't remeber who it was who said they were also doing this. -- Marco Ring the bells that still can ring. Forget the perfect offering. There is a crack in everything. That's how the light gets in. -Leonard Cohen

[slime-devel] Re: Using SLIME with LispWorks on Win2000
by Bill_Clementson＠peoplesoft.com 05 Mar '04

05 Mar '04

Below is a patch that will allow you to use SLIME with the LispWorks WIN32 Windows application on the LispWorks Personal Edition for Windows. You won't be able to start LW via an inferior lisp with "M-x slime"; however, you can use a similar approach to what I described in my earlier post regarding ACL for Windows.

[slime-devel] SLIME adding its own layer of confusion to error messages
by Peter Seibel 05 Mar '04

05 Mar '04

Here's an error message I got in my *sdb* buffer: #<CONSTANT-POOL-IDX @ #x75b9f21a> cannot be converted to a pathname. [Condition of type TYPE-ERROR] Restarts: 0: [ABORT] Return to SLIME toplevel. 1: [ABORT] Abort entirely from this process. If we look at the backtrace around lines 5 and 6 we see that the real problem was a NO-APPLICABLE-METHOD which is somehow causing SWANK to pass my object to SWANK:PATHNAME-AS-DIRECTORY.
