Data::Hexdumper Description

Data::Hexdumper can make binary data human-readable. Data::Hexdumper can make binary data human-readable.SYNOPSIS use Data::Hexdumper qw(hexdump); $results = hexdump( data => $data, # what to dump number_format => 'S', # display as unsigned 'shorts' start_position => 100, # start at this offset ... end_position => 148 # ... and end at this offset ); print $results;Data::Hexdumper provides a simple way to format arbitary binary data into a nice human-readable format, somewhat similar to the Unix 'hexdump' utility.It gives the programmer a considerable degree of flexibility in how the data is formatted, with sensible defaults. It is envisaged that it will primarily be of use for those wrestling alligators in the swamp of binary file formats, which is why it was written in the first place.SUBROUTINESThe following subroutines are exported by default, although this is deprecated and will be removed in some future version. Please pretend that you need to ask the module to export them to you.If you do assume that the module will always export them, then you may also assume that your code will break at some point after 1 Aug 2012.hexdumpDoes everything. Takes a hash of parameters, one of which is mandatory, the rest having sensible defaults if not specified. Available parameters are:dataA scalar containing the binary data we're interested in. This is mandatory.start_positionAn integer telling us where in data to start dumping. Defaults to the beginning of data.end_positionAn integer telling us where in data to stop dumping. Defaults to the end of data.number_formatA character specifying how to format the data. This tells us whether the data consists of bytes, shorts (16-bit values), longs (32-bit values), and whether they are big- or little-endian. The permissible values are C, S, n, v, L, N, and V, having exactly the same meanings as they do in unpack. It defaults to 'C'.suppress_warningsMake this true if you want to suppress any warnings - such as that your data may have been padded with NULLs if it didn't exactly fit into an integer number of words, or if you do something that is deprecated.space_as_spaceMake this true if you want spaces (ASCII character 0x20) to be printed as spaces Otherwise, spaces will be printed as full stops / periods (ASCII 0x2E).
