[slime-devel] How to determine the top caller in Slime's REPL
by Philippe-André Lorin 09 Jun '06

09 Jun '06

Hello everybody. I'm a Slime newbie, trying to develop an application that is intended to be run in Emacs + Slime to allow for interactive modifications. I posted this to comp.lang.lisp, but got few replies; it is probably more appropriate here. In Slime, I need to be able to determine dynamically whether the "top caller" of the currently executing code is some specifically marked expression, or just one of all the other expressions typed at the REPL which might be running in parallel. An example should make the idea clearer. (defun f () ; This function is just here to show that the (in-marked-expression)) ; test is not necessarily lexically enclosed ; in the marked expression. (mark-and-eval (do () (nil) ; Just an infinite loop, to make sure the ; expression will be running forever in parallel. (assert (f)))) ; Here, IN-MARKED-EXPRESSION must always return T. (f) ; Note that the preceding (DO ...) is still running. => NIL ; Here, IN-MARKED-EXPRESSION must always return NIL. I can write the marked expression with complete freedom (for instance, I can add wrappers around it or preprocess it), but all the other expressions typed after it at the REPL are not under my control. Among the ideas I've tested, the following one sounded the most promising, but it doesn't work. I don't understand why. (defun in-marked-expression () (not (null (find-restart 'restart-in-restart-case)))) ; Are we in the ; restart-case? (defun f () (in-marked-expression)) (restart-case (do () (nil) (assert (f))) (restart-in-restart-case () nil)) (f) => T ; :( I also tried using a special variable or processes, with no luck. Any ideas? PS: I'm using CMUL on Ubuntu.

[slime-devel] Slime/CMU hangs on GC
by Florian Ebeling 05 Jun '06

05 Jun '06

My emacs in slime mode hangs quite oft imidiatly after announcing a GC run, usually from a Slime mode buffer, not from REPL. I use CMUCL and Slime from CVS. Is this a known behaviour? Florian -- Florian Ebeling florian.ebeling(a)gmail.com

[slime-devel] slime-apropos problem
by jcb 05 Jun '06

05 Jun '06

slime-apropos is behaving strangely on my system: PowerBook G4 Mac OS X 10.4.6 sbcl 0.9.13 Aquamacs 0.9.9c Here is what happens: 1. Start SLIME M-x slime 2. Try slime-apropos on "*package*" C-c C-d a SLIME Apropos: *package* 3. Check % CPU activity in Activity Monitor.app: the sbcl process hovers constantly at around 85%. It makes the fans come on :-). slime-apropos seems to work ok with e.g. "defun". Try it with "*default-pathname-defaults*", and it'll peg the sbcl process. This behavior happens with both SLIME from CVS and SLIME 2.0. Clues? Known issue? Anymore info needed...? Thanks..

[slime-devel] Better .asd
by Greg Pfeil 04 Jun '06

04 Jun '06

After being confused as to why (asdf:oos 'asdf:load-op :swank) wasn't working, I decided to look at the source to figure it out. The problem was that I was using ASDF-Binary-Locations to store my fasls elsewhere on the disk, and once swank-loader.fasl was put in the alternate location, it couldn't find any of the other swank .lisp files. I created a new swank.asd that contains (I think) the full functionality of swank-loader.lisp. This allows the fasls to be relocated. I know, this means that changes have to happen in two places. I think there's a solution to this, too. Rather than have the .asd call swank-loader, reverse it. Write a new swank-loader that just loads the .asd (untested): (defvar *source-directory* (make-pathname :name nil :type nil :defaults (or *load-pathname* *default-pathname- defaults*)) "The directory where to look for the source.") (handler-case (require :asdf) (condition () (load (make-pathname "asdf" :defaults *source-directory*)) (pushnew *source-directory* asdf:*central-registry* :test #'equal))) (asdf:oos 'asdf:load-op :swank) This tries to use an ASDF outside of the swank directory first, but falls back to an included one if need be. Then it loads the system. This means that for the time being, slim.e-el (and anyone setting the slime-backend custom variable) doesn't have to change anything. I know, it adds a dependency, but asdf is pretty ubiquitous anymore, and the inclusion of a fallback version in the source should catch a lot of the other cases. Cons: - requires ASDF Pros: - can eliminate a bunch of code used to manage file locations - gain flexibility of ASDF and its extensions (like ASDF-Binary- Locations) It also seems like SWANK maybe should be made into its own ASDF- Installable package, with SLIME having only the emacs code and SWINE having the Climacs code. Does anyone think any of this might be a good idea?

[slime-devel] Duplicate definitions in slime-edit-definition
by Chris Dean 01 Jun '06

01 Jun '06

I'm not sure if this happens in other Lisps, but in LispWorks I start to get duplicate definitions listed when I used SLIME-EDIT-DEFINITION to jump to a function. These are all the "same" function definition, just with a slightly different line numbers as I make changes to whatever .lisp file I'm editing and recompile the function. (This sure is tricky to explain!) I made a change to slime-edit-definition to remove the duplicates. Patch below. If this only happens in LispWorks I can modify swank-lispworks.lisp instead.
