SYNOPSIS

DESCRIPTION

Text::CountString is the module for counting the frequency of words.

METHOD

below methods are exported.

count_string($target_text, $string)

    warn count_string("a b c d a b c", "a"); # 2

To get the frequency count of strings

Also you can get counts of bulk strings

    my $result = count_string(
        "There is more than one way to do it.",
        "o", "e", "h",
    );
    warn $result->{o}; # 4
    warn $result->{e}; # 4
    warn $result->{h}; # 2

CHANGE IMPLEMENTS

This module can switch implements for counting string.

By default, to count strings is invoked by the regexp implement. Generally, It's fast enough.

    use Text::CountString

However, if you can guess that there are many many matched strings, then the 'split implement' is faster than regexp implement. So the internal implement can be switched 'regexp' to 'split' like below.

    use Text::CountString qw/split/;
