Data::HexDump::XXD can turn out useful.

A long time ago (almost 14 years!) I liked the output of vimโ€™s utility xxd so much that I wrote a module to re-generate its output in Perl. This is where Data::HexDump::XXD comes from.

(Technically speaking I donโ€™t know whether xxd is distributed as a part of vim, but it is surely distributed with vim).

The usage is pretty straightforward: feed it with bytes, get a string back. Or: feed it with a hex dump, get the bytes back. Like this:

use Data::HexDump::XXD qw( xxd xxd_r );
my $dump_string = xxd($binary_data);
my @dumped_lines = xxd($binary_data);
my $binary = xxd_r($xxd_like_string);
my $binary = xxd_r(@xxd_like_lines);

This is one of the modules from that had the most success so far: it is optionally used by another module if the user wants a hex dump of something. If youโ€™re skeptical, take a look at Devel::StringInfo!

All this fame will make my ego explode one day or another ๐Ÿ˜„
