I think it could make sense to make incf and < work with characters (and not convert them to int). Things get tricky with (+ ?a 1) ;; Return char (+ ?a ?z) ;; Signal error? Jan

Whatever happened to 21.1.8? 24 years, 6 months

Jake Colman

Was 21.1.8 ever released? I remember the maintainer mentioning that he was about to release it several weekends ago but I don't recall having seen it.

No idea, but that's what FSF does, and I copied it intentionally. I suppose we could ask RMS.

You check whether the bug is fixed in Ilya Zakharevich latest version (which it probably is) and then do the sync that is long overdue :-). If it is not fixed by Ilya., you do the sync anyway, Ilya is again the maintainer and you mail it him. Problem Solved :-) Jan P.S. The only really import XEmacs specific stuff in our versions is the support for delete-key-deletes-backwards. IIRC

I very often use isearch to just look something up below and then type C-g to get back where I was. Although I am trying to get used to using vcursor.el for that kind of stuff. Jan

Now that we have your attention. I have been wanting to look into this for some time, but still haven't come around to it. Are there any bottlenecks or imperfections with EIEIO that could be solved with a little help from the C core? For instance I am thinking of opaque-cons (car cdr) Internal function. Like cons, but the return value is an opaque type and will signal an error unless passed to opaque-* opaque-car (ocons) opaque-cdr (ocons) opaque-to-cons (ocons) opaque-cons-p (ocons) Then you would have in usertype.el (defun deftype (type operations) (put type 'type-operations operations) (define-function (make-symbol (cons "make-" (symbol-name type))) '(value) `(opaque-cons ,type value)) (define-function (make-symbol (cons (symbol-name type))) "-value" '(t) `((let ((c (opaque-to-cons t))) (if (eq (car c) ,type) (cdr c) (error 'type-error "...."))))) (define-function (make-symbol (cons (symbol-name type))) "-p" '(t) `(and (opaque-cons-p t) (eq (opaque-car t) ,type)))) etc Jan

A lot of the conversions are implicit, like in the loops you mentioned. (let ((myvar ?a)) (while (<= myvar ?z) (insert myvar) (setq myvar (1+ myvar)))) (For this case it would be sufficient to have int->char conversion work in ascii.)

Hi! I get the following error: console-msw.c ..\src\lisp.h(2138) : error C2143: syntax error : missing ')' before '*' ..\src\lisp.h(2138) : error C2143: syntax error : missing '{' before '*' ..\src\lisp.h(2138) : error C2059: syntax error : ')' ..\src\lisp.h(2138) : error C2059: syntax error : ';' NMAKE : fatal error U1077: 'cl' : return code '0x2' Stop. The culprit seems to be 'uid_t'. Where is it defined? Thanks, norbert.

The same as now -- ?¡. That's not perfect, but it's good enough for me. People who want other Latin charsets can use make-char. Additionally, the same code will work with and without Mule, now that non-Mule XEmacs has make-char.

cperl-mode bugs 24 years, 6 months

Hrvoje Niksic

Who do I report cperl-mode bugs to? Bob Olson and Ilya Zakharevich are listed as authors, and "XEmacs Development Team" as maintainer, but the bug I want to report is not XEmacs-specific.
