Re: Alternative for a directory builder

[atcroft]

I used the same idea, but File::Spec to parse the filename/directory portions when I was testing the following, which may help if you need portability later:

use strict;
use warnings;
use File::Spec;

my $p = q{/var/www/vhosts/testing.com/httpdocs/test1.html};
my ( $v, $d, $f ) = File::Spec->splitpath( $p ); 
my @dp = File::Spec->splitdir( $d ); 
foreach my $i ( 0 .. $#dp ) { 
  next unless ( $i and length $dp[$i] ); 
  print File::Spec->catdir( @dp[0 .. $i ] ), qq{\n}; 
}

For my sample data, the code gave me the following output:

/var
/var/www
/var/www/vhosts
/var/www/vhosts/testing.com
/var/www/vhosts/testing.com/httpdocs

Hope that helps.

Update 2011-02-22

I was able to come up with a map solution that seemed to work, although I believe others may have better solutions:

use strict;
use warnings;
use File::Spec;

my $p = q{/var/www/vhosts/testing.com/httpdocs/test1.html};
my ( $v, $d, $f ) = File::Spec->splitpath( $p ); 
my @dp = File::Spec->splitdir( $d ); 
print join( qq{\n}, 
        map{ if (! defined $dq ) { $dq = q{/}; } $dq .= $_ . q{/}; } 
        grep{ m/.+/; } 
        @dp ), qq{\n};

or, the following:

use strict;
use warnings;
use File::Spec;

my $p = q{/var/www/vhosts/testing.com/httpdocs/test1.html};
my ( $v, $d, $f ) = File::Spec->splitpath( $p ); 
my @dp = File::Spec->splitdir( $d ); 
print join( qq{\n}, 
        map{ File::Spec->catdir( @dp[0 .. $_] ) } 
        grep{ length $dp[$_]; } 
        0 .. $#dp ), qq{\n};
