[slime-devel] encoding problem ?
I am just starting to use slime (2.0) and noticed the following problem (which may not be a problem but I can't seem to find a solution): I have a source file that includes Japanese, English and French, it is encoded in UTF-8 and when I load it I get:
invalid byte #xE7 in CHARSET:ASCII conversion [Condition of type SIMPLE-ERROR]
Restarts: 0: [ABORT-REQUEST] Abort handling SLIME request. 1: [ABORT] ABORT
Backtrace: <snip>
Is there any way out of this ? If I can't use Unicode to be able to work with multiple languages it really is a pity. Jean-Christophe Helary ps I use CLISP.
In your .emacs you do it like this, so you can not just set the needed coding-system but also have it different depending on the lisp implmenetation used: (require 'slime) (setf slime-lisp-implementations '((sbcl ("sbcl") :coding-system utf-8-unix) (clisp ("clisp") :coding-system utf-8-unix) (cmucl ("lisp") :coding-system iso-latin-1-unix))) (slime-setup) -- Ignas Mikalajūnas

Ignas, thank you for your suggestion. FYI, I am a total Slime/Emacs beginner so I am not sure I understand everything that is going on here... My .emacs for Slime is: ;; slime-mode (add-to-list 'load-path "/Users/bubu/Library/Application\ Support/ Emacs/slime-mode/") (setq inferior-lisp-program "/sw/bin/clisp") (require 'slime) (setf slime-lisp-implementations '((clisp ("clisp") :coding-system utf-8-unix))) (setq slime-net-coding-system 'utf-8-unix) (slime-setup) And I still have the following message when I want to load my file:
invalid byte #xE7 in CHARSET:ASCII conversion [Condition of type SIMPLE-ERROR]
Since I don't understand the error message itself I really have no idea where to look for information. I have set my "Multilingual Environment" to UTF-8 too. I can open the file for edit without any problem, and it shows the Japanese and the French. Even if I set the multilingual environment to Ascii the file is properly opened. Jean-Christophe Helary

Harald,

You don't tell us how you load the file, but my guess is that you are not doing (load filename :external-format :utf-8). Right?
You are absolutely right. I am trying to go through the Practical Common Lisp book so it is needless to say that I was not even aware that such an option existed. The way I try to load the file is simply: (load "~/path/to/file.txt") For practical purposes I would like to have Slime understand that my default is UTF-8, since I mostly deal with mulilingual files with not overlapping character sets. I think I managed to have Emacs (I use Aquamacs) understand that, since all the .lisp multilingual files I have are properly displayed, so the next step would be to have Slime get that too :) Besides, after I tried: (load "~/Documents/_travail/Programmes/lisp/salut_2.lisp" :external- format :utf-8) I got yet another error message:
OPEN: illegal :EXTERNAL-FORMAT argument :UTF-8 [Condition of type SIMPLE-TYPE-ERROR]
I just checked that the file was properly saved in utf-8. Regards, Jean-Christophe

I had somehow jumped to the totally unsupported conclusion that you were running a (not too old) SBCL. If you're running a different Lisp, you may need to check the documentation for that Lisp, or ask on a mailing list for that Lisp. - Harald
Well, at least I know where to look for info now :) Thanks. JC On 2006/04/25, at 18:47, Harald Hanche-Olsen wrote:

On clisp, the legal arguments for :EXTERNAL-FORMAT are in the package CHARSET.

Pascal, Thank you very much for the help. The only place where I could find any kind of reference about :EXTERNAL-FORMAT was the "implementation notes" on the CLISP page. I wonder if there is a more accessible page for people like me :) I don't mind reading docs but I need to have a few things clearly spelled out before I know where to check...

Well, the Hyperspec page about OPEN mentions it, but the only value that you can give to it portably is :DEFAULT http://www.lispworks.com/documentation/HyperSpec/Body/f_open.htm All the other values are implementation dependant, hence the need to look at the specific implementation notes. -- __Pascal_Bourguignon__ _ Software patents are endangering () ASCII ribbon against html email (o_ the computer industry all around /\ 1962:DO20I=1.100 //\ the world http://lpf.ai.mit.edu/ 2001:my($f)=`fortune`; V_/ http://petition.eurolinux.org/

How is it possible to give the :external-format argument when doing C- c C-l ? Or rather, is there a way to inform SLIME that the external format is UTF-8 by default ? Jean-Christophe Helary

This answer is getting long-ish, because I want to show you how you could discover the answer to these questions on your own ... In a lisp buffer, type C-h k C-c C-l. You get a help buffer saying C-c C-l runs the command slime-load-file which is an interactive Lisp function in `slime'. Click on the underlined word `slime'. This will take you to the definition of slime-load-file in slime.el: (defun slime-load-file (filename) "Load the Lisp file FILENAME." (interactive (list (read-file-name "Load file: " nil nil nil (if (buffer-file-name) (file-name-nondirectory (buffer-file-name)))))) (let ((lisp-filename (slime-to-lisp-filename (expand-file-name filename)))) (slime-eval-with-transcript `(swank:load-file ,lisp-filename)))) Evidently, there is no ready made way to do what you want: It eventually runs (swank:load-file lisp-filename) in the backend lisp. So you can look up that function: In the slime-repl buffer, run (describe #'swank:load-file). Not terribly helpful. But you can place the cursor over the function name and type M-. (meta-period) which will lead you to the function definition: (defslimefun load-file (filename) (to-string (load filename))) So if you were to say (in-package :swank) (defslimefun load-file (filename) (to-string (load filename :external-format charset:utf-8))) and arrange for this to be loaded after swank.lisp, you should have what you want. The alternative is to tell your lisp to use UTF-8 as the default charset for all load operations. You will have to study the Lisp's documentation for hints on how to do that. - Harald

In clisp, by :DEFAULT, CUSTOM:*DEFAULT-FILE-ENCODING* is used. -- __Pascal Bourguignon__ http://www.informatimago.com/ READ THIS BEFORE OPENING PACKAGE: According to certain suggested versions of the Grand Unified Theory, the primary particles constituting this product may decay to nothingness within the next four hundred million years.

Can I do that from Slime ? Or from Emacs ? Jean-Christophe Helary
