autoinsert emacs lisp header

autoinsert emacs lisp header

[Ye Wenbin]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing  
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


The minibuffer-help-form for emacs lisp header in auto-insert-alist
seem format with wrong format-string. The format-string is:

(format "%10.0s:  %s" (car x) (cdr x))

which gives only whitespace.

By the way, if you use autoinsert for emacs lisp file, update
skeleton to newest version, there is a bug for "-N" skeleton element.

Indeed.  Does

(format "%12s:  %s" (car x) (cdr x))

give the desired format?

Could you please be a bit more specific?

I mean, the skeleton.el I used has bug for -N element.
skeleton-internal-1 use char-or-string-p to capture element string, char,  
and integer.
But negative number is not a char, so char-or-string-p return nil.
When use auto-insert for emacs lisp header, a error "Lisp nesting exceeds  
max-lisp-eval-depth"
will raise.

I checked the cvs version of skeleton, the bug is fixed now.

(char-or-string-p -2) returns t, hence the first branch of that
conditional should be taken.  Could you check why it doesn't for you?

Could you try to debug skeleton-internal-1?

Sorry, maybe I use emacs-23, that the reason we got different result.

Sorry, I forgot that this has been changed for the Unicode branch.
The bug is explained here

http://lists.gnu.org/archive/html/emacs-devel/2007-09/msg00105.html

and seems to have been fixed :-)
