[slime-devel] Different lisps, different coding systems
by Harald Hanche-Olsen 22 Nov '05

22 Nov '05

I have this in my .emacs: (setf slime-lisp-implementations '((sbcl ("sbcl") :coding-system utf-8-unix) (cmucl ("cmucl") :coding-system iso-latin-1-unix))) (setf slime-default-lisp 'sbcl) This works mostly, but not if I first run a slime with sbcl and then run another with cmucl in the same emacs. (It doesn't matter if I quit the slime one or not.) Before I tell you what happens, let me lay the blame at the feet of the global variable slime-net-coding-system. It is set iso-latin-1-unix after I start a cmucl slime. It becomes utf-8-unix after I run an sbcl slime, and is not reset to iso-latin-1-unix when I run a cmucl slime. But if I reset it manually, the problem does not occur. So what IS the problem, then? What I see in the *inferior-lisp* buffer is as follows: ;; Swank started at port: 54163. nil ;;; COMMON-LISP-USER: Error in function lisp::assert-error: The assertion (eq swank-backend::ef ':iso-latin-1-unix) failed. [Condition of type simple-error] Restarts: 0: [continue] Retry assertion. 1: [abort ] Return to Top-Level. Debug (type H for help) (lisp::assert-error (eq swank-backend::ef ':iso-latin-1-unix) nil nil) Source: Error finding source: File-error in function lisp::fd-open: Error opening #P"target:code/macros.lisp", Permission denied. 0] Error in function lisp::assert-error: The assertion (eq swank-backend::ef ':iso-latin-1-unix) failed. Error flushed ... 0] Error in function lisp::assert-error: The assertion (eq swank-backend::ef ':iso-latin-1-unix) failed. Error flushed ... and this repeats forever until I kill the Lisp. - Harald

[slime-devel] CVS version fails in xemacs21-nomule
by Liam M. Healy 22 Nov '05

22 Nov '05

The new CVS slime.el has a function (defcustom slime-repl-history-file-coding-system (cond ((featurep 'xemacs) (cond ((find-coding-system 'utf-8-unix) 'utf-8-unix) (t (coding-system-name default-buffer-file-coding-system)))) ((coding-system-p 'utf-8-unix) 'utf-8-unix) (t 'emacs-mule-unix)) "*The coding system for the history file." :type 'symbol :group 'slime-repl) but find-coding-system and coding-system-name are nonexistent in xemacs21-nomule and thus slime fails to load. There are conditionalizations elsewhere in the file on coding system functions, but not here. Liam

[slime-devel] Coding systems and .slime-history.eld
by Harald Hanche-Olsen 21 Nov '05

21 Nov '05

Of course I had to start playing with utf-8-unix as the coding system for communications between emacs/slime and the sbcl backend, and of course I had to test it by trying some commands with non-latin-1 characters in them. Everything went fine until I quit slime, when it wanted to save the history to .slime-history.eld with the latin-1 charset (I have not yet converted to utf-8 for everything I do). This failed of course, which makes me wonder whether slime-repl-save-history ought to have anticipated this problem, and specified the coding system, perhaps to be the same as communicating with the lisp? Of course, slime-repl-read-history-internal runs into the same snag. I could fix this for my own part by adding ("\\.eld$" . utf-8) to file-coding-system-alist or some other trick like that, or even moving to utf-8 as the default coding for all operations, by setting coding-system-for-write and coding-system-for-read both to utf-8. But slime users should not be forced to such measures just because they use utf-8 to talk to their lisp. - Harald

[slime-devel] Slime fails to load

Slime suddenly stopped working, cause unknown. Using either the Gentoo version or using the latest CVS downloaded today, when attempting to start Slime in emacs I end up with the following output. The REPL prompt never appears. Please advise how I may restore a functioning slime.

[slime-devel] Error on startup: Servname not supported
by Peter Gijsels 16 Nov '05

16 Nov '05

> ..., when I went to start slime, I ran > into some problems. > Specifically, the command buffer in emacs states: > itimer "run-with-timer" signaled: (error "127.0.0.1/(^W1^H& Servname > not supported for ai_socktype") > I'm running XEmacs 21.4.17, and my clisp --version reports Software: > GNU C 4.0.2. I'm running on the "breezy" version of Kubuntu Linux > (Ubuntu). I'm seeing the same problem with the same XEmacs, also on Kubuntu (5.10). It seems that open-network-stream won't work with a number as a port argument. As a work-around you can add the following function to your slime.el and replace the 2 calls to open-network-stream with my-open-network-stream: (defun my-open-network-stream (name buffer host port) (open-network-stream name buffer host (if (numberp port) (number-to-string port) port) 'tcp)) When you google around a bit it seems that there was indeed a problem with open-network-stream in that XEmacs version.

[slime-devel] BUG in macroexpand
by Marco Monteiro 15 Nov '05

15 Nov '05

There is a bug in macroexpand functionality: it fails to macroexpand (using C-c <ret>, for example) a form when the point is at the end of the last line of the buffer. Add a newline, or even a space, and it works. To reproduce: In a lisp source buffer, go to the last line in the buffer, type '(+ 1 1)' and now, without adding anything and with the point after the close parentheses, macroexpand it. If there is a line after the line with (+ 1 1) form, it works. Marco

[slime-devel] New error loading slime

I've been using my current combination of slime/cmucl for weeks without any trace of trouble, but when I tried to invoke a new session this evening, it gave me this error message: Any idea what would cause this?
