Remove broken symlinks with IO::All

[Dylan]

This is a short script using IO::All to remove broken symlinks.

Note, it has to redefine the readlink() method, because as of version 0.35 of IO::All, readlink doesn't handle relative symlinks.

IO::All sure makes my life easier!

#!/usr/bin/perl
use strict;
use warnings;
use IO::All::Link; # Because we redefine readlink()...
use IO::All;

my $file = shift @ARGV || '.';
my @ios = ( io($file) );

while (my $io = shift @ios) {
    if ($io->is_dir) {
        push @ios, $io->all;
    } elsif ($io->is_link and not $io->readlink->exists) {
        print "$io is broken, removing.\n";
        $io->unlink;
    }
}

# this has been submitted as a patch to IO::All...
no warnings 'redefine';
sub IO::All::Link::readlink {
    my $io = shift;
    my $path = CORE::readlink($io->name);
    unless (File::Spec->file_name_is_absolute($path)) {
        $path = File::Spec->join($io->filepath, $path);
    }
    IO::All->new($path);
}
