If it's possible given the time constraints and cvs tagging activity, I'd be happy if the preferred-communication-style checked only :sb-thread, and if the slime release notes for 1.2 required an sbcl of 0.8.21 or later. Would that be OK with you guys? Sorry for the eleventh-hour (or even later) change request... Cheers, Christophe

[slime-devel] Slime and :sb-futex on recent CVS SBCLs
by Andreas Fuchs 18 Apr '05

18 Apr '05

Hi, current SLIME CVS's swank-sbcl.lisp, function preferred-communication-style contains an assumption that is no longer true about recent SBCLs. Since 0.8.21, usefully threaded SBCL builds don't include :sb-futex in their feature list any more. Still, Swank checks for the presence of :sb-futex on the *features* list before adding the :spawn communication-style. I'm not entirely sure which of SBCL or SLIME needs to be fixed. Either SBCL should start including :sb-futex on its *feature* list again (or some other feature saying that threads are non-broken on this lisp build), or SLIME should stop checking for :sb-futex (which will break on SBCLs older than 0.8.21). Here's the (proof of concept) patch to make slime choose the right communication-style for 0.8.21 or later (but not earlier. I know no practical way to find out if we're running in SBCL version >=X): --- swank-sbcl.lisp 9 Apr 2005 07:07:00 -0000 1.129 +++ swank-sbcl.lisp 18 Apr 2005 22:27:45 -0000 @@ -42,8 +42,7 @@ ;;; TCP Server (defimplementation preferred-communication-style () - (if (and (sb-int:featurep :sb-thread) - (sb-int:featurep :sb-futex)) + (if (and (sb-int:featurep :sb-thread)) :spawn :fd-handler)) Cheers, -- Andreas Fuchs, <asf(a)boinkor.net>, asf(a)jabber.at, antifuchs

[slime-devel] custom indentation of macros
by Chris Capel 18 Apr '05

18 Apr '05

I think there should be a way to specify, in a source file for a CL macro, how SLIME should indent the macro. There is already a robust and capable, if under-documented, way to specify the indentation for arbitrary forms in cl-indent.el, and so it would be nice to wrap this up in a nice way and give it some SLIME support. My idea is to have SWANK look for a property on the CL symbols, custom-indent-spec, that, if present, has a list (or perhaps a string that can be read as a list in Emacs) that can be assigned to the common-lisp-indent-function property on the Emacs symbol to modify the indentation. It'd be nice to have some documentation for the format of this list, too. Anyway, here's the sort of thing I think would work. (setf (get 'defclass-ext 'custom-indent-spec) '((6 4 defclass-slots-options-indent) (defun defclass-slots-options-indent (path state indent-point sexp-column normal-indent) (if (> (length path) 1) (1+ sexp-column) 2)))) The above form is Common Lisp and contained in the source file, either after the macro definition or somewhere else. The quoted list (caddr of the setf form) is written in Emacs lisp. (Symbol case issues? Should everything in the Emacs-destined form be downcased by SLIME or something?) The first form in that list is the value the common-lisp-indent-function property on the Emacs symbol gets set to. The subsequent forms are function definitions that can be used in the first. My example would allow the following indentation: (defclass-ext some-class () (slot-a :a :ia slot-b :a (:if 2))) There should be some attention to name collision across packages--Emacs lisp symbols don't have packages, so two different CL authors with a macro with the same name and custom indentation could potentially collide in unpleasant ways. I think what has to happen is that SLIME adds and removes the common-lisp-indent-function property on Emacs symbols every time a package is switched, based on what is set up for the inferior lisp's symbols in the new package. Is this last bit feasible? Perhaps SLIME could check to make sure the Emacs symbols have been set up with the correct plists before every indentation, resetting them all if the package has changed since then. Other ideas?

[slime-devel] Release?
by Helmut Eller 17 Apr '05

17 Apr '05

Is there anything left that we should fix before the release? If not, can we release the baby in the next few days? I used 1.2 as version number in the documentation, because there was already a 1.1 CVS tag (from November, before the Unicode changes). I hope that's ok with everybody. Helmut.

[slime-devel] Double newlines sent to clisp on user input
by Alex Farran 17 Apr '05

17 Apr '05

I'm running through Practical Common Lisp using SLIME + clisp on slackware, and I've run into a problem in chapter 3 with the prompt-for-cd function: (defun prompt-for-cd () (make-cd (prompt-read "Title") (prompt-read "Artist") (or (parse-integer (prompt-read "Rating") :junk-allowed t)) (y-or-n-p "Ripped [y/n]: "))) If I run clisp in a terminal it works as expected: [6]> (prompt-for-cd) Title: La Peste Artist: Alabama 3 Rating: 5 Ripped [y/n]: (y/n) y (:TITLE "La Peste" :ARTIST "Alabama 3" :RATING 5 :RIPPED T) But in SLIME this happens: CL-USER> (prompt-for-cd) Title: La Peste Artist: Rating: 5 Ripped [y/n]: (y/n) Please answer with y or n : y (:TITLE "La Peste" :ARTIST "" :RATING 5 :RIPPED T) It seems that for every one newline I enter two are sent. Is there something I can configure to fix it? I've tried running SLIME with my existing emacs and clisp and also with the versions compiled as part of the lisp-in-a-box package. I get the same problem either way. Alex

[slime-devel] selective macroexpansion patch
by Chris Capel 16 Apr '05

16 Apr '05

I have a patch and new file that implements a few functions that allow the selective expansion of subforms. I have the beginnings of a new mode, but my very limited familiarity with Emacs/SLIME programming ensures that it's almost useless. I'm hoping the improvements will be obvious and trivial to make this more usable. I'm kind of puzzled about why my returned forms are printing out with every symbol qualified by its package. Also, the new function slime-macroexpand-expand-subform should probably make the expansion be undoable with one undo, instead of two. I don't have the keybindings set up for the new mode, and slime-mode could probably use a key and menu entry to open the buffer. swank-loader.lisp will need to be modified appropriately. I wasn't sure what to do here, as swank-source-path-parser.lisp was only loaded for SBCL and CMUCL. Is it really that unportable? I guess this is a good first stab. I might look at it some more, see if I can clean it up some, if no one else does. Chris Capel New file: swank-expander.lisp ;;;; Selective macro expander ;;; These are some macros that will macroexpand a specific subform of a form ;;; once (destructively), respecting macros locally established by macrolets and ;;; symbol-macrolets. ;;; There are currently some limitations. swank-source-path-parser.lisp doesn't ;;; currently return the path of the specific atom the cursor is on--only the ;;; list. So it's not possible to expand symbol-macros until this situation is ;;; improved. Also, forms that expand into macrolets that are not expanded ;;; before expanding the subform will not respect the macrolet. ;;; For example, with ;;; ;;; (defmacro foo (&body body) ;;; `(macrolet ((bar (x) `(y ,x))) ;;; ,@body))) ;;; ;;; expanding the subform in ;;; ;;; (foo (bar xyz)) ;;; ;;; will not be effective unless FOO is added to ;;; *macroexpand-macro-binding-form* (in-package :swank-backend) (defparameter *macroexpand-macro-binding-form* '((macrolet 2) (symbol-macrolet 2)) "This is a specification for forms that are expected to expand into forms that bind symbols to macros.

[slime-devel] SLIME via ssh?
by Nicolas Neuss 14 Apr '05

14 Apr '05

Hello, I have SBCL running on an Opteron Cluster (at the moment only one process). This cluster has no Emacs installed. I can connect to it only with ssh. 1. Is it possible to control the remote SBCL job with SLIME running on my own computer (a Laptop)? Can SLIME work also with remote files via Tramp (e.g. by sending expressions to the remote SBCL)? How is the setup? 2. It would be nice if the SBCL job could be kept running (doing a lengthy calculation) while I disconnect and log out (e.g. when carrying my Laptop to another place). What is the right thing to do here? Maybe screen or detachtty? Both are not installed yet, but this would probably be easy... Thanks for any hints, Nicolas.
