I found that little can be done on debugging a variable on print, after
visiting a page containing the module PadWalker.

I wonder whether in Perl can do something like:

$newline = '\n'

print
foo
$foo

print $newline;

I use the vim editor, in this sense, rapid coding and debugging can achieve.
But i at least know that the newline trick doesn't work...

Hi,

I'm struggling with my flac->mp3 music library maintenance script. based
on some net articles I have used MP3::Tag to attach cover art this way

use constant HEADER => ( chr(0x0) , "image/jpeg" , chr(0x0), "");

$img = new Image::Magick;
if (! $img->Read("$flacdir/cover.jpg")) {
$id3v2->add_frame( "APIC", HEADER, $img->ImageToBlob(magick => 'jpg'));
}

There is also setting

MP3::Tag->config("id3v23_unsync_size_w" => "TRUE");

See e.g. http://perl.thiesen.org/scripts/id3image

But I get corrupted cover art images in Amarok. iTunes and Windows Media
Player seem to work with it. MediaTomb uPnP server + PS3 doesn't find
the pictures. I'd like to get MediaTomb that uses taglib for metadata to
work.

I'm trying to remotely look at the NIC cards on W2K3 servers that I have
admin accounts on. When I run the following it gives me an error:

use strict;
use Win32::IPConfig;

my $ipconfig;
my $host = "some IP address"; # Changed the IP address for posting
$ipconfig = Win32::IPConfig->new($host); # This is where it fails when
ran with admin account.
print "hostname=", $ipconfig->get_hostname, "\n"; # This is where it
fails when ran without admin account.

This happens with admin account
C:\NIC>nic.pl
Can't use an undefined value as an ARRAY reference at
C:/Perl/site/lib/Win32/TieRegistry.pm line 720.

This happens without using admin account (It's not first getting
Win32::IPConfig->new($host))
C:\NIC>nic.pl
Can't call method "get_hostname" on an undefined value at C:\\NIC\nic1.pl
line 7.

Apologies to Perl purists - comp.infosystems.www.authoring.cgi doesn't
work on my newsreader, and this is a CGI question:

What I want to do is, I've got a large collection of image files:
$ wc gallery-pix
37448 62619 3218967 gallery-pix

and what I'd like to do is look at each of the 37488 image files on
some kind of page, with buttons like "Keep", "Skip", and "Quit",
so I can page through all of these images, which are strewn all
over the Samba server, and decide which ones might look good on
the website.

So, is it possible to do something like (in pseudocode):

for each $line in {
show webpage with tag, and the three buttons;
get button response, decide what to do with file;
if button == "Quit", save place in source file;
next;

or so?

Thanks,
Rich

8.14: How do I modify the shadow password file on a Unix system?

If perl was installed correctly and your shadow library was written
properly, the getpw*() functions described in perlfunc should in theory
provide (read-only) access to entries in the shadow password file. To
change the file, make a new shadow password file (the format varies from
system to system--see passwd for specifics) and use pwd_mkdb(8) to
install it (see pwd_mkdb for more details).

Hi,

Normally CPAN documentation is quite good.

However I'm having some problems with ImageMagick.

Could anybody point me to some good concise documentation.

Reading the Imagemagick documentation and guestimating how to pass the
same parameters to the perl equivalemt is not always simple:

Example:

Assume following ImageMagic command:

convert -size 64x64 xc:transparent -pointsize 10 -draw "text 0,20
'hello'" test.png

I'd like to do the same in perl:

my $g = Image::Magick->new;
$g->Set(size=>"64x64");
$g->ReadImage('xc:transparent');
$g->Draw( primitive => 'text', BUT_WHAT_IS_THE_SYNTAX_HERE_???? );
$g->Write("test.png");

and don't really know where to look.

Any hint / document is welcome

bye

8.21: Where do I get the include files to do ioctl() or syscall()?

Historically, these would be generated by the h2ph tool, part of the
standard perl distribution. This program converts cpp(1) directives in C
header files to files containing subroutine definitions, like
&SYS_getitimer, which you can use as arguments to your functions. It
doesn't work perfectly, but it usually gets most of the job done. Simple
files like errno.h, syscall.h, and socket.h were fine, but the hard ones
like ioctl.h nearly always need to hand-edited. Here's how to install
the *.ph files:

1. become super-user
2. cd /usr/include
3. h2ph *.h */*.h

Hello, and thanks in advance for your help. I have code (below) used
for adding emails from a user textbox to a flat file. The user is
asked to separate emails with a carriage return. Some times they will
use 2 carriage returns. The code is designed to separate emails by
returns, remove returns and then add them before writing. It is not
working perfectly. Some times chopping the last letter off, sometimes
not removing carriage returns. I'm sure there is a better way to do
this. Any help is appreciated.
