6 Data::Binary - Simple detection of binary versus text in strings
7
9 use Data::Binary qw(is_text is_binary);
10 my $text = File::Slurp::read_file("test1.doc");
11 my $is_text = is_text($text); # equivalent to -T "test1.doc"
12 my $is_binary = is_binary($text); # equivalent to -B "test1.doc"
13
15 This simple module provides string equivalents to the -T / -B
16 operators. Since these only work on file names and file handles, this
17 module provides the same functions but on strings.
18
19 Note that the actual implementation is currently different, basically
20 because the -T / -B functions are in C/XS, and this module is written
21 in pure Perl. For now, anyway.
22
24 is_text($string)
25 Uses the same kind of heuristics in -T, but applies them to a string.
26 Returns true if the string is basically text.
27
28 is_binary($string)
29 Uses the same kind of heuristics in -B, but applies them to a string.
30 Returns true if the string is basically binary.
