Data::HexDump(3) User Contributed Perl Documentation Data::HexDump(3)
NAME
Data::HexDump - Hexadecial Dumper
SYNOPSIS
Functional interface:
use Data::HexDump;
print HexDump($data_string);
OO interface:
use Data::HexDump;
my $dumper = Data::HexDump->new();
print while $_ = $dumper->dump;
DESCRIPTION
This module will generate a hexadecimal dump of a data string or file.
You can either use the exported function, as shown in the SYNOPSIS
above, or the OO interface, described below.
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).
Functional Interface
This module exports a single function, "HexDump", which takes a scalar
value and returns a string which contains the hexdump of the passed
data.
OO Interface
You first construct a "Data::HexDump" object, then tell it where to get
the data from, and then generate the hex dump:
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;
The different potential sources for data are considered in the order
given above, so if you pass to the "data" method, then any subsequent
calls to "fh()" or "file()" will have no effect.
SEE ALSO
Data::Hexify(3), by Johan Vromans, is another simple option, similar to
this module. Last release in 2004.
Data::Hexdumper(3) (by David Cantrell, DCANTRELL) is another hex
dumper, with more features than this module.
App::colourhexdump(3) (by Kent Fredric, RIP) provides a script which
gives colourised output with character class highlighting.
Data::HexDump::Range(3) provides more functions, colour output, and the
ability to skip uninteresting parts of the input data.
Data::HexDump::XXD(3) 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(3) provides some configuration options, but there are
other more featured modules, and this one doesn't have example output
in the doc.
Data::Peek(3) is a collection of functions for displaying data,
including "DHexDump" which generates a simple hex dump from a string.
String::HexConvert(3) will convert ASCII strings to hex and reverse.
