Yeah; I need to ask the Gnus people to apply it too. But for the moment I’m
worried about XEmacs-specific compatibility.

Yes. The XEmacs char tables are opaque objects, not vectors.
Okay, and now I check, I realise my “portable” code fails on GNU
Emacs. Here’s a version that works there, where char-tables are sequences
and really close to being vectors, though not quite:
(defun-when-void put-display-table (range value display-table)
"Set the value for char RANGE to VALUE in DISPLAY-TABLE. "
(if (sequencep display-table)
(aset display-table range value)
(put-char-table range value display-table)))
(defun-when-void get-display-table (character display-table)
"Find value for CHARACTER in DISPLAY-TABLE. "
(if (sequencep display-table)
(aref display-table character)
(get-char-table character display-table)))

disp-table.el, which provides the display table code--make-display-table,
frob-display-table, describe-display-table, and in
http://mid.gmane.org/18288.1954.87217.762309＠parhasard.net ,
put-display-table and get-display-table--is in core. Yeah, there’s a decent
argument that it might be better in packages, but it isn’t there for the
moment. There isn’t any other obvious place to put these two functions, IMO,
and moving them away from #'make-display-table and #'describe-display-table
will make for less clear code.
The defun-when-void means any existing definition won’t be overridden.

Workaround for browse-url and friends on Windows
16 years, 3 months
Pete Forman
[retry]
I've just updated from 21.5.17 to 21.5.28 on XP native using the
pre-built binary kit. I found that clicking on links no longer opened
them in my external browser. A simple illustration in *scratch* is:
(mswindows-shell-execute "open" "http://www.xemacs.org/")
21.5.17 successfully opens the page in my external browser. 21.5.28
gives the following error:
Process error: Running ShellExecute, "The system cannot find the file
specified. ", "open", "http://www.xemacs.org/"
Ben Wing put his hand up for this in a message of 2005-10-20:
http://article.gmane.org/gmane.emacs.xemacs.beta/20772
So a workaround is to set mswindows-shortcuts-are-symlinks to nil.
Links now work.
Another example that needs the workaround is:
(mswindows-shell-execute "explore" "c:")

quail: TeX input method: change UTF8 to tex and back: solution & problems
16 years, 3 months
Uwe Brauer
Hello
Some days ago I asked for an equivalent to iso-unaccentuate for quail
input methods. Since as I learnt xemacs does not use the GNU Emacs
idea of multi-byte chars, iso-unaccentuate should work without
problems for ó and the like.
Now I asked for a similar feature for the TeX input methods:
TeX-2-utf8(TeXtuate)
\int ---------------> ∫
utf8-2-TeX(TeXuntuate)
∫ ---------------> \int
Now I looked into a attic package (1994)
iso-sgml, (written by Frederic Lepied <lepied(a)cenaath.cena.dgac.fr>),
whose logic I could understand,
which changed iso-8859-1 chars to the SGML entities.
A main point was the variable sgml2iso-trans-tab, which looks
basically like:
(defvar sgml2iso-trans-tab
'(
("Æ\;" "Æ")
))
Which changed Æ to Æ and back.
So I boldly modified the variable to the following
(defvar tex2utf8symb-trans-tab
'(
("\int" "∫")
))
I am not sure whether I could treat ∫ as a string, for example in the
file latin-ltx.el I see
("\\int" ?∫)
Anyhow the code worked, but there is a problem:
(defvar tex2utf8symb-trans-tab
'(
("\\in" "∈")
("\\infty" "∞")
("\\int" "∫")
))
While
\in and \int are transformed correctly
\infty is changed to ∈fty,
which is wrong (on the other hand I don't understand why
\int is not transformed to ∈t but anyhow).
So the question is how shall I define the tex commands uniquely?
thanks

C99 and inline
16 years, 3 months
Jerry James
I can't seem to reproduce the C99 + inline problem on my machine. If
I'm not mistaken, all of the reports of this problem so far have come
from Mac OS X users. Would one of you please try applying this patch
and building with -std=c99 or -std=gnu99 and see if it works?

Re: Do we need gnus-yes-or-no-p and gnus-y-or-n-p?
16 years, 3 months
Katsumi Yamaoka
Hi,
In the Gnus mailing list, now it is being discussed whether the
behavior of `y-or-n-p' that it does not clear the echo area is
intentional. While `yes-or-no-p' clears the question and the
answer in the echo area after entering `y e s' or `n o' and RET,
`y-or-n-p' does not do so after entering `y' or `n'. E.g.:
(defun foo ()
"Switch to buffer named foo."
(interactive)
(when (y-or-n-p "Switch to buffer foo? ")
(switch-to-buffer "foo")))
(Please try it with `yes-or-no-p' as well.)
The behavior of `y-or-n-p' that it doesn't clear the question
and the answer is not serious of course, but I feel it is not
cool. Lars seems to have felt it like me and introduced the
function `gnus-y-or-n-p' in February, 1995:
(defun gnus-y-or-n-p (prompt)
(prog1
(y-or-n-p prompt)
(message "")))
Currently, it is commented out in the trunk by Reiner Steib. He
also wrote the benefit of leaving the question and the answer in
the echo area as follows:
(http://article.gmane.org/gmane.emacs.gnus.general/66061)
> In contrast to yes-or-no-p it is much easier to type y, n,
> SPC, DEL, etc accidentally, so it might be useful for the user
> to see what he has typed.
(You can read the whole thread in:
http://news.gmane.org/group/gmane.emacs.gnus.general/thread=65099/force_l...)
But I like the behavior that it clears the echo area like
`yes-or-no-p', even if it is a side effect of the RET key.
Could someone draw the conclusion? And if it is regarded as a
bug, I hope it is fixed in the future (in that case, we need to
uncomment `gnus-y-or-n-p' for old Emacsen).
Regards,

[Bug: 21.5-b28] Bug in #'loop
16 years, 3 months
Aidan Kehoe
================================================================
Dear Bug Team!
Sebastian Freundt just pointed this out:
(loop for i in t always nil)
=> t
Common Lisp errors because t isn’t a list, as is consistent with the
behaviour when you hand our #'loop a sequence, say. Here’s a tentative fix
that I have yet to test in detail; the SXEmacs folk and Sebastian in
particular have a pretty comprehensive test suite available, though, and I
intend to get to testing it soon.

pre-built binary kit. I found that clicking on links no longer opened
them in my external browser. A simple illustration in *scratch* is:
(mswindows-shell-execute "open" "http://www.xemacs.org/")
21.5.17 successfully opens the page in my external browser. 21.5.28
gives the following error:
Process error: Running ShellExecute, "The system cannot find the file
specified. ", "open", "http://www.xemacs.org/"
Ben Wing put his hand up for this is a message of 2005-10-20:
http://article.gmane.org/gmane.emacs.xemacs.beta/20772
So a workaround is to set mswindows-shortcuts-are-symlinks to nil.
Links now work.
Another example that needs the workaround is:
(mswindows-shell-execute "explore" "c:")

recursive edebug-eval-defun till a certain level?????
16 years, 3 months
Uwe Brauer
Hello
May be this is a lisp programmers (wet) dream (or nightmare):
according to the documentation
edebug-eval-defun only debugs the top-level of a given function.
However I think it might be very useful that the debugging includes
several levels more.
Does anybody know about a package doing this?
Thanks and regards
Uwe Brauer

I found the line (110) in XEmacs src/esd.c that was the root of the problem:
sock = esd_play_stream(flags, speed, NULL, ESD_NAME);
The function in esdlib is prototyped as int esd_play_stream( esd_format_t
format, int rate, const char *host, const char *name );
Passing the value NULL for the host worked until I recompiled XEmacs for
Leopard. esd expects a host name or an octet string (with optional
port/socketname appended). But the code in esdlib is supposed to accept !host
as a signal to use localhost.
However, it doesnot to work because of the new scheme for setting DISPLAY in OS
X.
If I change the call from XEmacs so that the NULL is replaced by "localhost",
the sound plays. If I change the code in esdlib.c so that esd_play_stream
checks for host==NULL and calls esd_open_sound("localhost") instead of
esd_open_sound(NULL), then the sounds will also work. Either "fix" gets the
sounds back.
I have not tried the third alternative of setting the environment variable
ESPEAKER to "localhost". It might also work; however, on the previous OS
(10.4), setting ESPEAKER caused hangups in XEmacs. On 10.3, it was the only
way to get esd to play.
I just wanted to followup in case anyone else using OS X 10.5 found a similar
problem with sounds.
BTW: Is anyone working on a way to use CoreAudio from within XEmacs--similar to
the way Windows sound is treated?

How to suppress environment variable expansion by find-file?
16 years, 3 months
Skip Montanaro
I have a file with a leading dollar sign in its name. When I try to visit
it in XEmacs I get an error with this message "substituting nonexistent
environment variable ...". I've tried doubling up the dollar sign, escaping
it with a backslash, quoting it with apostrophes and giving a prefix
argument. I didn't see any variable which would obviously suppress the
expansion. Nothing seems to work. Is there any relief for this problem?
Thanks,
Skip Montanaro
