NAME¶
Data::Binary - Simple detection of binary versus text in strings
SYNOPSIS¶
use Data::Binary qw(is_text is_binary);
my $text = File::Slurp::read_file("test1.doc");
my $is_text = is_text($text); # equivalent to -T "test1.doc"
my $is_binary = is_binary($text); # equivalent to -B "test1.doc"
DESCRIPTION¶
This simple module provides string equivalents to the -T / -B operators. Since these only work on file names and file handles, this module provides the same functions but on strings.
Note that the actual implementation is currently different, basically because the -T / -B functions are in C/XS, and this module is written in pure Perl. For now, anyway.
FUNCTIONS¶
is_text($string)¶
Uses the same kind of heuristics in -T, but applies them to a string. Returns true if the string is basically text.
is_binary($string)¶
Uses the same kind of heuristics in -B, but applies them to a string. Returns true if the string is basically binary.
