Data::...p::XXD(3pm)

💖 Data::...p::XXD 💖

okay so first of all bestie, yes, the manual name is literally Data::...p::XXD with the dots and everything, it's the 3pm section of the manual, and the docs are User Contributed Perl Documentation. Iconic. Truncated. We love her. 💅

---

✨ NAME ✨

Data::HexDump::XXD — formats a hexadecimal dump the way xxd does it. That's the whole job. She does it well. 🦋

---

🌸 VERSION 🌸

This document describes Data::HexDump::XXD version 0.0.1. ✨

---

💜 SYNOPSIS 💜

   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);

that's it. that's the whole vibe. 🎀

---

🦋 DESCRIPTION 🦋

she produces a hexadecimal dump exactly like the program xxd would do, and she does the reverse too. both directions, no cap. 🔥

at the moment, only straight dumping is supported, and reverse assumes the same. so like, don't come at her with the fancy xxd options, she's doing the basic thing and she's doing it slay. 💅

---

🌈 INTERFACE 🌈

my $dump = xxd($bindata);

my @dump_lines = xxd($bindata);

my $dump = xxd_unpack($bindata);

my @dump_lines = xxd_unpack($bindata);

produces a hex dump of the input $bindata, bestie. the dump comes back either as a single string or as a list of lines — it literally depends on the calling context, so my $dump = ... gives you the string, my @dump_lines = ... gives you the lines. same function, different glow-up depending on what you asked for. ✨

xxd_unpack() and xxd() are synonimous. (that's the doc's spelling, keep it, iykyk 🫶)

my $bindata = xxd_r($dump);

my $bindata = xxd_r(@dump_lines);

my $bindata = xxd_pack($dump);

my $bindata = xxd_pack(@dump_lines);

reverses an xxd-style hexadecimal dump back into binary. 🧚 you can hand her either a single string or an array of lines — and if you give her the single string, the line terminator is assumed to be a single newline character, that's the default, no negotiating.

and like xxd itself does, the ASCII dump is ignored and only the hexadecimal part is taken into account. she's not reading the right-hand side, she's not judging it, she's just grabbing the hex. 💖

---

🎀 CONFIGURATION AND ENVIRONMENT 🎀

Data::HexDump::XXD requires no configuration files and no environment variables. zero setup. she just works. main character energy fr fr. 👑

---

⭐ DEPENDENCIES ⭐

among the non-core stuff, only version. that's the entire guest list. 🙈

---

💀 BUGS AND LIMITATIONS 💀

she's currently limited to the basic behaviour of xxd. that's the boundary, bestie, respect the boundary. 🌸

note that a plain hex dump is pretty straightforward in Perl, you literally just have to call:

   my $hex = unpack 'H*', $bindata;

note also that the high nybble is always assumed to come first in dumps (see perldoc -f unpack, the H template). so that's a real assumption, not a suggestion. 🫶

no bugs have been reported. 😌

please report any bugs or feature requests through http://rt.cpan.org/ — go through the proper channels, she reads them, she's not ignoring you. 💜
