Hi -
I am a bit confused about how to set $! from within an xs module. I have
searched perlxstut, perlxs, and perlguts without really understanding what
is involved. Can some one either point me to a module that sets $! or give
me a short description on how it is done?
Thanks!
an existing .ai file:
#!/usr/bin/perl
use strict;
use warnings FATAL = all;
use Mac::Glue qw( :all );
my $ill = Mac::Glue::-new( Adobe Illustrator )
or die cannot get Illustrator: $^E\n;
my $file = video-test.ai;
$ill-open( $file, ERRORS = 1 );
yields:
rocky:test beau$ perl hello.pl
Adobe
the double quotes:
\\n\
works.

No, there is no way. You must write your prepended lines to a
new file and then append your old file, and, delste ( or
rename to a backup) your old file, and rename your new file back to the old
file. All easy to do with Perl.

You need a regular expression. Also, where is $i initialized?
Try something lik this:
for (@LineFromFile) {

You and always execute your script by first specifying the
Perl executable:
/some/othet/perl/bin/perl script.pl

in an array is returned when
you access that array in 'scalar' cintext; there are
many ways to do this:
my $count = @fields;
print number of fields = $count\n;
printf number of fields = %d\n, scalar @fields;
etc, etc.

Hi -
A little OT, but, with Perl runing under Linux,
is there any way to get the 'target' file name
of a 'soft' link? Or even determine a filename
is a 'soft' link? (By 'soft' I mean a link
created so: ln -s target link).
