Hello Monks, I got stuck with a "Can't use an undefined value as an ARRAY reference at ..." error
when trying to push a struct using MooX::Struct onto an array. Please apologize I am still a novice monk and I don't understand why
this error happens. I probably did some smaller or larger mistake, but have no clue what could be wrong. :(
Here a stripped-down piece of code. It fails at the line with the push.
use strict;
use warnings;
use diagnostics;
use 5.014; # so push/pop/etc work on scalars (experimental)
use MooX::Struct -rw, Dirnode => [ qw( $dirname @subdlist ) ];
my $dirroot = crawldir( ".");
sub crawldir {
my $curpath = shift;
my $dno = Dirnode[];
$dno->dirname( $curpath );
opendir(DIR, $curpath);
my @files = readdir(DIR);
closedir(DIR);
print "crawldir in directory ", $dno->dirname, "\n";
foreach (@files) {
next if $_ eq '.' or $_ eq '..';
my $file_path = "$curpath/$_";
$file_path =~ s|/+|/|g;
if (-d $file_path) {
print "crawldir in directory ", $dno->dirname, ": calling c
+rawldir( $curpath\/$_)\n";
push @{$dno->subdlist}, crawldir( "$curpath\/$_" );
}
}
return $dno;
}
