NAME
    Lingua::Boolean - DEPRECATED module to comprehensively parse boolean
    response strings

VERSION
    version 0.008

SYNOPSIS
        use Lingua::Boolean; # NO! Don't use it - use Lingua::Boolean::Tiny

        # Use functional/procedural interface
        print "Do it? ";
        chomp(my $response = <>);
        if ( boolean $response ) {   # YES, y, OK, 1...
            print "OK, doing it.\n";
        }
        else {                      # no, N, 0...
            print "OK, not doing it.\n";
        }

        # Once more, with feeling
        print "Fait-le? ";
        chomp($response = <>);
        if ( boolean $response, 'fr' ) {    # OUI
            print "OK, on le fait.\n";
        }
        else {                              # non
            print "OK, on ne le fait pas.\n";
        }

        # Or, use OO interface
        my $bool = Lingua::Boolean->new('en');
        print "Do it? ";
        chomp($response = <>);
        if ($bool->boolean($response)) {
            print "OK, doing it!\n";
        }
        else {
            print "OK, not doing it.\n";
        }

DESCRIPTION
    This module is deprecated. It began as an experiment with the concept,
    as well as API design. The experiment worked -- we proved that this
    module has a bad interface. If you are still interested in the
    conceptual experiment, give Lingua::Boolean::Tiny a try.

    Does that string look like they said "true" or "false"? To know, you
    have to check a lot of things. "Lingua::Boolean" attempts to do that in
    a single module, and do so for multiple languages.

METHODS
    "Lingua::Boolean" provides both functional/procedural and
    object-oriented interfaces. Everything described below is an object
    method, but can also be called as a function. "boolean()" is exported by
    default, and can be called that way - everything else requires the
    fully-qualified name.

        use Lingua::Boolean;
        my @languages = Lingua::Boolean::languages();
        print boolean('yes') . "\n"; # boolean is exported by default

  import
    Calling "import()" will, obviously, import subs into your namespace. By
    default, "Lingua::Boolean" imports the sub "boolean()". All other subs
    should be accessed with the object-oriented interface, or use the fully
    qualified name.

  new
    "new()" creates a new "Lingua::Boolean" object. You can optionally give
    it the code for the language you'll be working with, and only that
    language will be loaded. If you do so, you needn't pass the language to
    every call to "boolean()":

        use Lingua::Boolean qw();
        my $bool = Lingua::Boolean->new('fr');
        print ($bool->boolean('oui') ? "TRUE\n" : "FALSE\n");

    Otherwise, "boolean()" accept the language code as the second parameter:

        use Lingua::Boolean qw();
        my $bool = Lingua::Boolean->new();
        print ($bool->boolean('oui', 'fr') ? "TRUE\n" : "FALSE\n");

  boolean
    "boolean()" tries to determine if the string *looks* true or *looks*
    false, and returns true or false accordingly. If both tests fail, dies.
    By default, uses *en*; pass a language code as the second parameter to
    check another language. Croaks if the language is unknown to
    "Lingua::Boolean" (or the "Lingua::Boolean" object, if used as an object
    method).

        use Lingua::Boolean qw();
        my $bool = Lingua::Boolean->new();
        print ($bool->boolean('yes') ? "TRUE\n" : "FALSE\n");

    If you specify the language in the constructor, you needn't specify it
    in the call to "boolean()":

        use Lingua::Boolean qw();
        my $bool = Lingua::Boolean->new('fr');
        print ($bool->boolean('OUI') ? "TRUE\n" : "FALSE\n");

    This sub is exported by default, and can be used functionally:

        use Lingua::Boolean;
        print (boolean('yes') ? "TRUE\n" : "FALSE\n");

  languages
    "languages()" returns the list of languages that "Lingua::Boolean" knows
    about.

        use Lingua::Boolean;
        my @languages = Lingua::Boolean::languages(); # qw(English Français ...)

    When called as an object method, returns the languages that that object
    knows about:

        use Lingua::Boolean qw();
        my $bool = Lingua::Boolean->new('fr');
        my @languages = $bool->languages(); # qw(Français)

  langs
    "langs()" returns the list of language *codes* that "Lingua::Boolean"
    knows about.

        use Lingua::Boolean;
        my @lang_codes = Lingua::Boolean::langs(); # qw(en fr ...)

    When called as an object method, returns the languages that that object
    knows about:

        use Lingua::Boolean qw();
        my $bool = Lingua::Boolean->new('fr');
        my @lang_codes = $bool->langs(); # qw(fr)

EXPORTS
    By default, "Lingua::Boolean" exports "boolean()". All other methods
    must be fully qualified - or use the object-oriented interface.
