| Description: |
This is a routine I've used in the past to add files to an
Archive::Tar object (in the process of creating a tar archive).
My objective was to get relative paths in the archive, rather
than paths from the root.
Usage:
my $tar = Archive::Tar->new;
add_to_tar($tar, $thing_to_add, $base_dir);
$tar->write($gz, 9);
$thing_to_add can be either a file or a directory.
$base_dir is the key to relative paths. For example, say I had a
directory directory '/foo/bar', and in that directory is another
directory 'baz'. I can do something like this:
add_to_tar($tar, 'baz', '/foo/bar');
Alternatively, the second directory could contain the full path:
add_to_tar($tar, '/foo/bar/baz', '/foo/bar');
Hope this is useful. |
sub add_to_tar {
my($tar, $thing, $base) = @_;
if (defined $base) {
chdir $base or die "Can't chdir to $base: $!";
$thing =~ s!^$base/?!!;
}
if (-f $thing) {
$tar->add_files($thing);
}
elsif (-d $thing) {
my $code = sub {
return if !-f $_;
local *FH;
open FH, $_ or die "Can't open $_: $!";
binmode FH;
my $c = do { local $/; <FH> };
close FH or die "Can't close $_: $!";
$tar->add_data($File::Find::name, $c);
};
find $code, $thing;
}
}
