Sorry for the late response. CCL's swank backend uses threads by default, and threads inherit values from the global environment. *RANDOM-STATE* probably becomes thread-local automatically in CCL, resulting in the behaviour you described. It should work when you type in the form at the Slime REPL which evaluates all forms in the same thread. -T.

[slime-devel] slime-inspector-copy-down
by Chaitanya Gupta 03 Apr '09

03 Apr '09

Hello, The function slime-inspector-copy-down (bound to M-RET in the inspector) in slime.el has been commented out in cvs for some time. Is it going to be "uncommented" and brought back to life? Or is there an alternative function to do the same thing? Chaitanya

[slime-devel] unhooking from slime before saving sbcl core?
by Michael Hannemann 02 Mar '09

02 Mar '09

Hi all, I'm new to SLIME, although a co-worker has been prodding me to look at it for a year. I'm also new to SBCL, although I used CMUCL a fair amount several years ago. I apologize if the following is a FAQ -- I scoured the manual and searched through the gmane archives of this list, but I could've missed something. When I write a core image out from SBCL which I'm talking to via SLIME, then try to load it from the command line without SLIME, I get a long stream of warning messages. This happens immediately on startup. I've deleted my .sbclrc file so user init is not to blame. (Also, when I start up SBCL from the shell, this doesn't happen.) The lisp is not dead, just injured; I can get out of the break loop. However, any time I get back into a break loop, I'm in trouble again. My co-worker suggested setting *debugger-hook* to nil, so I tried that, to no avail. I still get the errors (example below), and once I get back to a usable prompt in the lisp, I see that it's set to SWANK:SWANK-DEBUGGER-HOOK again. I've copied the first chunk of what I see on startup to the end of this message. This is MacOSX, SLIME from CVS a day or two ago, SBCL 1.0.23. Any advice? Thanks, Michael --- * Help! 11 nested errors.

[slime-devel] abcl special inspector support for java classes, methods, and other good stuff
by Russell McManus 01 Mar '09

01 Mar '09

I have written a couple of dozen lines of code to improve the way the inspector works in abcl for certain java objects. At this point, I can't work without these improvements, but I haven't been able to quite figure out how to produce a proper patch to slime for inclusion. Normally, what i do is execute the following forms after swank is already loaded. This seems to work fine. However when I put all the following forms into swank-abcl.lisp, this approach fails because the swank package is not loaded yet. Any ideas about how I can get organize the following code so that it works cleanly with slime? Thanks, -russ Here is the code: ;; this is the troublesome form. where should it go? (defmethod swank:emacs-inspect ((java-object java-object)) (swank-backend::emacs-inspect-java java-object)) (defun swank-backend::emacs-inspect-java-class (jclass) (flet ((jclass->name (jclass) (let* ((s (jclass-name jclass)) (prefix "java.lang.") (lang-pos (search prefix s))) (if lang-pos (subseq s (+ lang-pos (length prefix))) s)))) (append `("Java Class: " ,(princ-to-string jclass) (:newline)) `("Methods" (:newline)) (loop for method across (jclass-methods jclass) for i = 0 then (1+ i) append (let ((args (mapcar #'jclass->name (coerce (jmethod-params method) 'list)))) `(,(format nil "[~2D] ~A ~A(~{~A~^,~}): ~40T" i (jclass->name (jmethod-return-type method)) (jmethod-name method) args) (:value ,method) (:newline))))))) (defun swank-backend::emacs-inspect-java-object (jobject) (let* ((jclass (jobject-class jobject)) (fields (coerce (jclass-fields jclass) 'list))) (append `("Java Object" ":" ,(princ-to-string jobject) (:newline)) `("Java Class" ":" ,(jclass-name jclass) " " (:value ,jclass) (:newline)) `("Fields" (:newline)) (loop for field in fields for i = 0 then (1+ i) append `(,(format nil "[~2D] ~20A : " i (jfield-name field)) (:value ,(jcall (jmethod (jclass "java.lang.reflect.Field") "get" (jclass "java.lang.Object")) field jobject)) (:newline)))))) (defun swank-backend::emacs-inspect-java-method (jmethod) (let ((return-type (jcall (jmethod (jclass "java.lang.reflect.Method") "getReturnType") jmethod)) (args (coerce (jmethod-params jmethod) 'list))) (setf args (mapcar (lambda (arg) (jclass-name arg)) args)) (append `("Java Method: " ,(jmethod-name jmethod) (:newline)) `("Return Type: " ,(jclass-name return-type) ": " (:value ,return-type) (:newline)) (if args (append `("Arguments" (:newline)) (loop for arg in args for i = 0 then (1+ i) append `(,(format nil "[~2D] ~20A : " i arg) (:value ,arg) (:newline)))) `("Arguments: none" (:newline)))))) (defun swank-backend::emacs-inspect-java (java-object) (flet ((is-a (class-name) (jinstance-of-p java-object (jclass class-name)))) (cond ((is-a "java.lang.Class") (swank-backend::emacs-inspect-java-class java-object)) ((is-a "java.lang.reflect.Method") (swank-backend::emacs-inspect-java-method java-object)) (t (swank-backend::emacs-inspect-java-object java-object)))))

[slime-devel] [PATCH] a few small fixes
by Stelian Ionescu 27 Feb '09

27 Feb '09

The first patch replaces old-style backquoting with the new-style in contrib/bridge.el(when compiling the file I got a warning that old-style backquotes are deprecated since version 21 and will be removed soon). The other patches fix two typos. -- Stelian Ionescu a.k.a. fe[nl]ix Quidquid latine dictum sit, altum videtur.

[slime-devel] Patch to fix occasional "jerky" slime-eval-last-expression
by szergling 27 Feb '09

27 Feb '09

Suppose I have 2 windows, 1 for Lisp code, another showing the REPL. Every time I C-xC-e in the Lisp-code buffer, it jerks downwards so that the current line (at point) becomes the last visible line in the window. This is because slime is attempting a (recenter -1), but with the wrong window. I have an older Emacs 21.4.1 here which doesn't have with-selected-window (a macro). The current (the last time I checked) "emulation" of with-selected-window defines a function instead of a macro. This causes evaluation of its body form at the wrong time/places. See eg slime-repl-show-maximum-output (the original source of my investigations and hence the subject of this email). Perhaps a macro equivalent to slime-defun-if-undefined could be used instead? Something like... ;; here, fboundp substitutes for macro-boundp (defmacro slime-defmacro-if-undefined (name &rest rest) `(unless (fboundp ',name) (defmacro ,name ,@rest))) Cheers!
