electric-perl-terminator leaves point at beginning of line on error |

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 address@hidden mailing
list,
and to the gnu.emacs.bug news group.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
In perl mode, entering the line-end { at the point shown in the
following closure:
{
sub tran {
# start of transition
my($e,%attrs) = @_;
my $line="";
if ( "TURN" eq $attrs{level} ){
# typing the { at the end of the following line gives scan error
# and leaves point at the beginning of line, which is a pain!
# fixed by changing progn to save-excursion in
electric-perl-terminator
if ( exists($attrs{
} else if ($wantlevel eq $attrs{level}){
}
}
}
causes the electric-perl-terminator function to stop with an error:
forward-sexp: Scan error: "Unbalanced parentheses", 16, 410
but it leaves me at the _beginning_ of the line. This means
that I cannot easily type in the line I want, which is:
if ( exists($attrs{tag}) ){
instead when I type that sequence of characters without pausing I end up
with:
tag}) ){ if ( exists($attrs{
This also happens under emacs 21.3.1 on Linux and on a (modified)
22.3.1 on Windows.
It does not appear to happen in a number of simpler variants I tried
of the above source, so I do not quite understand what is going on.
A fix appears to be to replace the "progn" in
electric-perl-terminator with "save-excursion", so that when
perl-indent-line reports an error, the point remains where I want it.
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/22.3/etc/DEBUG for instructions.

I am sorry for the long delay. Hopefully this is now fixed, by stopping
perl-calculate-indent from throwing the error that was upsetting
perl-electric-terminator.
