NAME

SYNOPSIS

  use Data::HexDump;
  print HexDump($data_string);

OO interface:

  use Data::HexDump;
  my $dumper = Data::HexDump->new();
  print while $_ = $dumper->dump;

DESCRIPTION

The second example from the SYNOPSIS generated this output:

           00 01 02 03 04 05 06 07 - 08 09 0A 0B 0C 0D 0E 0F  0123456789ABCDEF

 00000000  23 21 2F 75 73 72 2F 62 - 69 6E 2F 70 65 72 6C 0A  #!/usr/bin/perl.
 00000010  75 73 65 20 73 74 72 69 - 63 74 3B 0A 75 73 65 20  use strict;.use
 00000020  77 61 72 6E 69 6E 67 73 - 3B 0A 0A 70 72 69 6E 74  warnings;..print
 00000030  20 22 48 65 6C 6C 6F 2C - 20 77 6F 72 6C 64 5C 6E   "Hello, world\n
 00000040  22 3B 0A                                           ";.

The result is returned in a string. Each line of the result consists of the offset in the source in the leftmost column of each line, followed by one or more columns of data from the source in hexadecimal. The rightmost column of each line shows the printable characters (all others are shown as single dots).

    my $dh = Data::HexDump->new();

    $dh->data($scalar);      # dump the data in this scalar
    $dh->fh($fh);            # read this filehandle
    $dh->file($filename);    # read this file and dump contents

    print while $_ = $dh->dump;

SEE ALSO

Data::Hexdumper (by David Cantrell, DCANTRELL) is another hex dumper, with more features than this module.

App::colourhexdump (by Kent Fredric, RIP) provides a script which gives colourised output with character class highlighting.

Data::HexDump::Range provides more functions, colour output, and the ability to skip uninteresting parts of the input data.

Data::HexDump::XXD provides hex dumps like xxd. It doesn't say what xxd is, or provide a link, and there's no example output. But if you know and like xxd, this might be the one for you!

Devel::Hexdump provides some configuration options, but there are other more featured modules, and this one doesn't have example output in the doc.

Data::Peek is a collection of functions for displaying data, including "DHexDump" which generates a simple hex dump from a string.

String::HexConvert will convert ASCII strings to hex and reverse.
