( #3333=superdoc: print w/replies, xml ) Need Help??
I'm having trouble installing extra modules on an active state (windows) perl installation. I download the zip file containing the necessary files and excute the install command in the README file (ppm install xxxx.ppd) and it finishes with no errors. When I try to use the module, however, I get errors. The most recent error was with an MP3 module:
#!/usr/bin/perl -w use strict; use MP3::ID3v1Tag; opendir(DIR, "H:\\test") || die "Unable to open directory: $!"; my @file_names = readdir(DIR); closedir(DIR); my ($title, $artist, $mp3_file); foreach my $file (@file_names) { $mp3_file = new MP3::ID3v1Tag("$file"); $title = $mp3_file->get_title(); $artist = $mp3_file ->get_artist(); print "$title - artist\n"; } and I get this error...... Can't open .: Permission denied at d:/Perl/site/lib/MP3/ID3vTag.pl lin +e 83 Can't call method "get_title" on an undefined value at rename.pl line +57
Any suggestions?

    choroba's discovered two instances of a weird animal in the code at work: \@$var
    [Eily]: hum, tied scalar, generates a new array when derefed ? :D
    [Corion]: choroba: Ah, when doing a shallow copy, I prefer [ @$var ] - I think \@$var might return the same reference instead of a reference to a fresh copy
    [Corion]: perl -wle "my $ar = [1,2,3]; my $br=\@$ar; print qq($ar / $br)" confirms this to me
    [karlgoethebier]: "discovered" this to sum an array: perl -E 'say scalar map {1 .. $_} (1..3);'
    [Corion]: karlgoethebier: Hahaha :)
