NAME
Lingua::Boolean - comprehensively parse boolean response strings
VERSION
version 0.003
SYNOPSIS
use Lingua::Boolean;
# 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
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 a 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.
