in reply to Creating a tarball


use Path::Tiny; path('fred')->visit( sub { -f || -d and $tar->add_files($_) }, {recurse => 1} );

EDIT: Fuller version (still untested):

use Archive::Tar; my $tar = Archive::Tar::->new(); my @filenamelist; use Path::Tiny; path('fred')->visit( sub { -f || -d and push @filenamelist, "$_" }, {recurse => 1} ); $tar->add_files(@filenamelist); $tar->write("fred.tar.gz", COMPRESS_GZIP);

SECOND EDIT: Because I like Path::Tiny better than File::Find, although it has its quirks. For example, in the callback, $_ is a Path::Tiny object instead of a plain string, hence the "$_" which "stringifies" it.

    I'd guard that against unreadable files:

    sub { -f || -d and push @filenamelist, "$_" }, => sub { -f || -d and -r and push @filenamelist, "$_" },

      Which leads to the question: Should these files be silently ignored, or an error or warning be generated?

      (And code gets more and more complicated :)

      G'day Tux,

      You raise a good point and, in general, my code is littered with such checks. However, in this instance, the directory structure is generated afresh immediately before the tarball creation, and the spec requires all files in the directory structure to be readable. So, while that is something I would normally do, it's not needed in this particular situation. Thanks for mentioning it anyway.

    G'day tybalt89,

    Thanks. That looks like a nice, succinct solution.

    I'm extending legacy code, which already uses Path::Tiny, so that removes any additional, dependency-related issues (e.g. Makefile.PL). I'll test this out tomorrow.

    By the way, thanks for the additional information, e.g. object stringification.

    Update: Added "[Path::Tiny]" to the title.

    I was happy to see your post using Path::Tiny's visit method. This works well for me:
