[slime-devel] swank-ecl & compile-from-stream
by Tomi Neste 18 Feb '06

18 Feb '06

Compile-from-stream in swank-ecl.lisp seems to generate and compile empty files which can be a bit confusing, the attached patch should fix that. T. Neste

[slime-devel] OK to install this SBCL pretty printer patch into SLIME CVS?
by Matthias Koeppe 16 Feb '06

16 Feb '06

Hi, I would like to install a new file, "sbcl-pprint-patch.lisp", into SLIME CVS. It patches the SBCL pretty printer, so as to support printing SLIME presentations through a pretty printing stream. The file will only be loaded when a user loads the SLIME file "present.lisp". A set of equivalent changes to the pretty printer have been included in CMUCL 19c. I have also tried to get the patch into SBCL, but it seems the maintainers are not interested in merging it. Any objections to installing it into SLIME CVS?

[slime-devel] Running CL code from elisp, and vice versa
by Harald Hanche-Olsen 13 Feb '06

13 Feb '06

Is there a convenient function for running bits of CL code (in the backend common lisp of course) from elisp? I've been playing around with slime-eval-with-transcript and slime-eval-async, with rather mixed success. Most commonly, I just get a protocol error and lose my slime connection. Am I looking in the wrong place, perhaps? Why do I want this? Say I am editing some (non-lisp) file and then want to process it by feeding the filename to some function in the CL backend. I'd like to be able to just run something like (slime-eval-thing `(process-file ,(buffer-file-name)) ":cl-user") and have the backend lisp run (process-file "/foo/bar") or whatever. And, while we're at it, how about the backend lisp asking emacs to run some elisp code? Most importantly, I want to be able to have the backend ask emacs to open a file, and perhaps move to a specified point in the file. I notice that the debugger seems able to do this, so surely, the functionality exist. But how accessible is it to the user? - Harald

[slime-devel] Editor Slime/Configuration
by Robert McAlpine 13 Feb '06

13 Feb '06

Hi, I'm using Aquamacs 0.9.8 and still getting to grips with lisp/slime etc etc These are probably just dumb emacs questions: I'd like to stop the REPL from converting the text to bold on execution/completion of the entered form. (it makes it hard to read on the LCD with anti-aliasing). ... and if at all possible I'd like to turn on syntax colouring in the REPL. (I've played with the customizations.el file and changed a couple of slime-repl ... forms but not got the results I'd like). Any pointers would be appreciated, Robert

[slime-devel] prompting the user from Lisp
by Taylor Campbell 12 Feb '06

12 Feb '06

The SLIME protocol currently provides, I believe, two operations for reading input from the Emacs user: the READ-STRING mechanism and a simple Y-OR-N-P device. In order to prompt the user for specific input, one must send a string to Emacs and then parse a string read from Emacs, but this is all line-oriented and provides no fancy input mechanisms on the user's side, such as completion, so it's hard to offer a convenient prompt to the user from the Lisp side, such as in restart functions. Does it sound like a good idea to define a (:PROMPT <prompt string> <input type>) RPC to be called from Lisp? For instance, a USE-VALUE restart might send (:PROMPT "Value to use instead:" EXPRESSION) to request input from the user, rather than printing the prompt directly to standard output and reading from standard input, as is usually done now. This way, Emacs would be given more leeway in presenting the prompt -- e.g., it might use the typein window instead of cluttering the REPL buffer --, and it would allow for completion, editing not restricted to lines (like the usual REPL prompt), &c. It is probably pretty easy to implement; I'll experiment with it soon, but I wondered what others thought about the matter.

hello, slime words very well with my Emacs configuration. I would like to use it with dettachtty, but i can't. i use : SBCL 0.9.7.1 and i have juste make a cvs update (last changelog entry 02/06/2006) so, i try to launch slime like this : $> detachtty --dribble-file /tmp/.dribble --log-file /tmp/.detachtty --pid-file /tmp/.pid /tmp/.socket \ /usr/bin/sbcl \ --eval "(push \"/home/nicolas/src/slime/\" asdf:*central-registry*)" \ --eval "(asdf:operate 'asdf:load-op :swank)" \ --eval "(setq swank:*use-dedicated-output-stream* nil)" --eval "(swank:create-swank-server 4008)" but i have an error (file attached to this mail) someone know how can i do to use slime with detachtty ? thanks for any help -- Nicolas Lamirault
