finding an implementation of SWANK interface
by 73budden . 06 Jan '18

06 Jan '18

Hi! Maybe I'm missing something, but I don't know how do I find defimplementation of some definterface. E.g. I want to go to swank/backend:activate-stepping, but EMACS only sends me to definterface, and I have to grep for defimplementation. I don't know how should I handle this, but I added a simple defparameter into defimplementation form. Now, when I'm asking for definition of swank/backend:activate-stepping, I see two suggested source locations: (defvar swank/backend:activate-stepping) (defun swank/backend:activate-stepping) defun is for definterface, defvar is for defimplementation. This works at least in SBCL, I guess it is handy. Patch is attached. This may seem a bit ugly, but SBCL does not suggest a way to extend its definition database with new classes, so I see no good way to go. WBR, Budden

Getting the source file pathname
by Chaitanya Gupta 09 Dec '17

09 Dec '17

Hi, I need the path of the source file from which a particular form is loaded (similar to __FILE__ in C). Currently I have the following macros in place: (defmacro source-pathname () (let ((compile-file-pathname *compile-file-pathname*)) `(or ,compile-file-pathname (load-time-value *load-pathname*)))) (defmacro source-truename () (let ((compile-file-truename *compile-file-truename*)) `(or ,compile-file-truename (load-time-value *load-truename*)))) (defmacro source-directory () `(make-pathname :defaults (source-truename) :name nil :type nil)) This works fine when I use (LOAD ...), (LOAD (COMPILE-FILE ...)), slime-load-file or slime-compile-and-load-file. However it fails when I use slime-compile-defun, slime-eval-defun or slime-eval-last-expression. Shouldn't slime bind *compile-file-pathname*, *load-pathname*, etc. when these functions are run? Thanks, Chaitanya

Trouble connecting to Swank running on android
by PR 04 Sep '17

04 Sep '17

Hi, I know that it's possible to run the Swank server on an android device, and connect to it from the PC (people did this successfully). Unfortunately it doesn't work for me... I enabled swank:*log-events*; attached you find 2 log files: - swank-events-log-1.txt: this one works (connecting locally) - swank-events-log-2.txt: this fails trying to connect to swank on android I tried many times, it always fails at the exact same point. I even tried using ssh, with the same result. Could anybody knowing the swank internals look into this, please? Thanks, Paul P.S. I'm trying this with the EQL5-Android REPL example, which can run (from same sources) both on the desktop and on android; so the logs mentioned above use the same application;

SLIME + Named readtables
by 73budden . 19 Aug '17

19 Aug '17

Hi! I have made a readtable-related pull request long time ago, it was not merged because it was breaking things that worked before. So I suggest to discuss another approach to SLIME + NAMED-READTABLES cooperation. Please see the essay here: https://bitbucket.org/budden/clcon/src/e3c40c555295336a3a13c506cce6a179f9dd…

how to copy a line from the back trace
by Jim Newton 03 Aug '17

03 Aug '17

Can someone tell me how I can grab a lisp expression from a stack trace, as in copy it in emacs so I can re-paste and potentially edit it in the repl? When I move the cursor to the line, the entire text displays in the echo area at the bottom of the emacs window, but when use use CNT-E to move to the end of the line, the line has been truncated and i see "..". I'd like to copy/paste the un-truncated line. I'm attaching images of what I see. Kind regards Jim

SWANK defines defstructs in the keyword package
by Martin Simmons 05 Jul '17

05 Jul '17

Hi, swank/backend.lisp defines some defstructs in the keyword package: (defstruct (:location (:type list) :named (:constructor make-location (buffer position &optional hints))) buffer position ;; Hints is a property list optionally containing: ;; :snippet SOURCE-TEXT ;; This is a snippet of the actual source text at the start of ;; the definition, which could be used in a text search. hints) (defstruct (:error (:type list) :named (:constructor)) message) ;;; Valid content for BUFFER slot (defstruct (:file (:type list) :named (:constructor)) name) (defstruct (:buffer (:type list) :named (:constructor)) name) (defstruct (:etags-file (:type list) :named (:constructor)) filename) ;;; Valid content for POSITION slot (defstruct (:position (:type list) :named (:constructor)) pos) (defstruct (:tag (:type list) :named (:constructor)) tag1 tag2) This is generally a bad idea because it can lead to clashes in the namespace of structure names (as used by the :include option). AFICS, except for "location", these definitions are never used because they are always constructed using backquote or list. Would you consider removing the defstructs and adding defuns for make-location and its readers? -- Martin Simmons LispWorks Ltd http://www.lispworks.com/

2nd repl for same inferior lisp
by Jim Newton 25 May '17

25 May '17

Hi, Can someone tell me how to (or if it is possible to) create a second repl buffer for the same inferior lisp process. Maybe this is not supported, because when I look in the slime manual, it seems to always refer to "THE REPL buffer for the current SLIME connection” Kind regards Jim

SLIME _may_ cause emacs to resize frame involuntarily
by Peter Keller 16 Apr '17

16 Apr '17

Hello, I discovered some odd behavior related to SLIME that I can't figure out. Hopefully, someone here can help me out. In short, starting SLIME with M-x slime or switching to a buffer containing the SLIME repl causes a resize of the emacs frame containing that buffer. The details are at this link (which is also a test config file that you can start emacs with that will hopefully demonstrate the problem): http://paste.lisp.org/display/344012 I'm using stock emacs 25.1, xubuntu 16.04 LTS, SBCL 1.3.12, and SLIME installed from Quicklisp and current as of 2017-04-10. If you store the linked data as a file like /tmp/init-resize.el you can run it as: emacs -q -l /tmp/init-resize.el (provided you have that font it is requesting, which is "DejaVu Sans Mono 9"). Then resize the window manually to 80x24, then M-x slime. If the bug presents itself, the frame will resize after slime is loaded to something other size. I think the resize is erroneous behavior. I provided what would have been the means that I thought would stop the involuntary resize in the init file, but it doesn't seem to work. Thank you! -pete
