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; } }

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
