I'm not sure why. I also use the REPL all the time and wouldn't like to see it removed. In fact, my normal modus operandi is to jump between source window and REPL, sometimes evaluating sexp's in the source window, sometimes evaluating them in the REPL. Generally, the one-off testing stuff is in the REPL; however, there are often times when I want to step through chunks of code from a source buffer in the REPL and "tweak" the code before it is executed. for that, I use the following function: (defun slime-present () (interactive) (setq *presentation-buffer* (current-buffer)) (global-set-key [f9] (lambda () (interactive) (set-buffer *presentation-buffer*) (forward-sexp) (let ((end (point)) (beg (save-excursion (backward-list 1) (point)))) (copy-region-as-kill-nomark beg end) (set-buffer (slime-output-buffer)) (unless (eq (current-buffer) (window-buffer)) (pop-to-buffer (current-buffer) t)) (goto-char (point-max)) (yank) (slime-reindent-defun) (delete-other-windows))))) This is also useful when I want to give a "slide show" type of presentation of some lisp code or when I want a "clean" REPL session (e.g. -- if I want to post it later to my weblog). So, to reiterate, I LIKE THE REPL. :-) > > Any outstanding keybinding wars? A while ago we talked about grouping > > documentation commands under C-c C-d; I like that idea. > > Agree.

While on the subject of the "grouping" commands, one personal little nitpick that I have is that I don't like the "C-c C-w m" type "grouped" commands. I find that it is easier (and less error prone) for me to type "C-c C-w C-m" instead of "C-c C-w m" because I don't have to lift my finger off the control key to press the m. This was something that we had a number of discussions about among the ILISP developers a while back and the general consensus was in support of the 3-control key sequence. What do others think about this? - Bill

[slime-devel] Broken readtables
by Alain.Picard＠memetrics.com 17 Jun '04

17 Jun '04

I have a file which defines a readtable so I can type things like #v(1 2). (Don't ask. :-) When I hit M-. to find any definition in this file, emacs croaks and asks if I want to enter recursive edit. Saying yes yields a SLDB buffer like this: Subcharacter #\v not defined for dispatch char #\#. [Condition of type CONDITIONS:SIMPLE-READER-ERROR] Restarts: 0: [ABORT] Abort handling SLIME request. 1: [ABORT] Quit process. Now, I grovelled a bit in the sources and found: (defvar *readtable-alist* '() "An alist mapping package names to readtables.") I tried to use this thusly: Try to add what I think is reasonable to this alist CL-USER> (push (cons "GRAPHICS" *readtable*) swank::*readtable-alist*) (("GRAPHICS" . #<READTABLE 202E1B84>)) Verify that it finds the right package CL-USER> (swank::guess-buffer-readtable "graphics") #<READTABLE 202E1B84> Make sure the correct table is in place: CL-USER> (get-dispatch-macro-character #\# #\v (swank::guess-buffer-readtable "graphics")) #<function GRAPHICS::VECTOR-READER 237CF9D2> (looks good). However, the next M-. failed in exactly the same way. Tracing GUESS-BUFFER-READTABLE, I found it was in fact calling it with argument ":graphics", which I thought sub-optimal, but, no matter: CL-USER> (push (cons ":graphics" *readtable*) swank::*readtable-alist*) ((":graphics" . #<READTABLE 202E1B84>) ("GRAPHICS" . #<READTABLE 202E1B84>)) Now, surely it will work, right? Nope. Any clues? Cheers, --ap

There's no reason to make a special exception for Win32 - I would prefer to have the directory name be the same for both Win32 and non-Win32 installs. Another advantage is that, in Emacs, you can elect to not have your dot directories displayed in dired buffers. This is my preference for the fasl directories as I don't normally want to drill down into them. - Bill

Historical Windows/Emacs reasons (older versions of NTEmacs required that the .emacs file be named "_emacs"; however, current versions allow you to use either "_emacs" or ".emacs" as the default initialization file name.) 2, Because some brain-dead Win32 programs won't let you create a file that starts with dot (Windows Explorer is a prime example). However, Emacs on Win32 will let you do this and if you're using slime, you're using Emacs, right? :-) In fact, now even notepad on Win32 will allow you to create files with a dot at the beginning of their name. > Bill, is there some code we can snarf from your blog to make > installation on Win32 easier?

[slime-devel] repl shortcut commands feature request
by Brian Downing 17 Jun '04

17 Jun '04

Continuing my attempts to spam slime-devel: I find the slime-repl comma shortcuts to be quite useful. However, it would be nice if when a comma shortcut was run, if a re-runable version of the command with its arguments could be put in the repl buffer and on the repl command history. That would seem make interacting with the repl a little bit nicer, as it would remove some of the discontinuity between lisp forms (you can see them in the repl buffer, and they can be called up with M-p) and repl commands (you can sometimes see their results in the repl buffer, and they cannot be called up with M-p.) I looked into doing this, but it wasn't immediately obvious to me how I'd accomplish it. (I was going to put the emacs form executed for the shortcut into the buffer prepended by a comma, much like you see the raw emacs forms when you use repeat-complex-command.) -bcd -- *** Brian Downing <bdowning at lavos dot net>

[slime-devel] SLIME, OpenMCL and aborting a process

Suppose I type (loop repeat 10000 do (sleep 0.5) (princ ".")) by "accident" in the listener. I'd like to stop this from running so that I can get back to work but don't see how? Also, no periods are printing. Where are they going? Are they filling up my computer like those little holes from a three hold punch? What if it runs out of space?
