The higher the level, the harder this function will try finding phone numbers,
but the higher the risk of false positives will be. E.g. in text
'123456789012345' with level=5 it will not find a phone number, but with level=9
it might assume, e.g. 1234567890 to be a phone number. Normally leaving level at
default level is fine.

Extracts phone number(s) from text. Return an array of one or more parsed phone
number structure (a hash). Understands the list of known area codes and cellular
operators, as well as other information. Understands various syntax e.g.
+62.22.1234567, [phone], 022-123-4567 ext 102, and even things like
7123456/57 (2 adjacent numbers).

Extraction algorithm is particularly targetted at classified ads text in
Indonesian language, but should be quite suitable for any other normal text.

Non-Indonesian phone numbers (e.g. [phone]) will still be extracted,
but without any other detailed information other than country code.

=head1 NAME

Parse::PhoneNumber::ID - Parse Indonesian phone numbers

=head1 VERSION

This document describes version 0.16 of Parse::PhoneNumber::ID (from Perl distribution Parse-PhoneNumber-ID), released on 2017-07-10.

=head1 SYNOPSIS

 use Parse::PhoneNumber::ID qw(parse_id_phone extract_id_phones);
 use Data::Dump;

 dd parse_id_phone(text => 'Jual dalmatian 2bl lucu2x. Hub: 7123 4567',
                   default_area_code=>'022');

Will print something like:

 { raw          => 'Hub: 7123 4567',
   pretty       => '022-7123-4567',
   standard     => '+62.22.71234567',
   is_cell      => 1,
   is_gsm       => 0,
   is_cdma      => 1,
   operator     => 'telkom',
   product      => 'flexi',
   area_code    => '022',
   province     => 'jabar',
   cities       => 'Bandung, Cimahi, ...',
   local_number => '71234567',
   country      => 'Indonesia',
   country_code => '62',
   ext          => undef, }

To extract more than one numbers in a text:

 my $phones = extract_id_phones(text => 'some text containing phone number(s):'.
                                        '0812 2345 6789, [phone]');
 say "There are ", scalar(@$phones), "phone number(s) found in text";
 for (@$phones) { say $_->{pretty} }

=head1 FUNCTIONS


=head2 extract_id_phones

Usage:

 extract_id_phones(%args) -> any

Extract phone number(s) from text.

Extracts phone number(s) from text. Return an array of one or more parsed phone
number structure (a hash). Understands the list of known area codes and cellular
operators, as well as other information. Understands various syntax e.g.
+62.22.1234567, [phone], 022-123-4567 ext 102, and even things like
7123456/57 (2 adjacent numbers).

Extraction algorithm is particularly targetted at classified ads text in
Indonesian language, but should be quite suitable for any other normal text.

Non-Indonesian phone numbers (e.g. [phone]) will still be extracted,
but without any other detailed information other than country code.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

=over 4

=item * B<default_area_code> => I<str>

When encountering a number without area code, use this.

If you want to extract numbers that doesn't contain area code (e.g. 7123 4567),
you'll need to provide this.

=item * B<level> => I<int> (default: 5)

How hard should the function extract numbers (1-9).

The higher the level, the harder this function will try finding phone numbers,
but the higher the risk of false positives will be. E.g. in text
'123456789012345' with level=5 it will not find a phone number, but with level=9
it might assume, e.g. 1234567890 to be a phone number. Normally leaving level at
default level is fine.

=item * B<max_numbers> => I<int>

=item * B<text>* => I<str>

Text containing phone numbers to extract from.

=back

Return value:  (any)


=head2 parse_id_phone

Usage:

 parse_id_phone(%args) -> any

Alias for extract_id_phones(..., max_numbers=>1)->[0].

Extracts phone number(s) from text. Return an array of one or more parsed phone
number structure (a hash). Understands the list of known area codes and cellular
operators, as well as other information. Understands various syntax e.g.

7123456/57 (2 adjacent numbers).

default level is fine.

=item * B<text>* => I<str>

Text containing phone numbers to extract from.
