VERSION
    This documentation describes version 0.01

SYNOPSIS
        use Business::DK::Phonenumber qw(validate render);
    
        #Validation
        if (Business::DK::Phonenumber->validate($phonenumber)) { ... }
    
        #Default format
        print Business::DK::Phonenumber->render($phonenum);
        # +45 12 34 56 78
    
        #Brief human readable Danish phone number format
        print Business::DK::Phonenumber->render($phonenum, '%08d');
        # 12345678
    
        #Normal human readable Danish phonenumber format
        print Business::DK::Phonenumber->render($phonenum, '%02d %02d %02d %02d');
        # 12 34 56 78

        #Generation of a single random number
        Business::DK::Phonenumber->generate();
    
        #Generation of 100 random numbers, using another template
        Business::DK::Phonenumber->generate(100, '%02d %02d %02d %02d');
        
DESCRIPTION
    This module offers functionality to validate, format and generate Danish
    phone numbers.

    The validation can recognise telephone numbers is the following formats
    as Danish phone numbers.

    * 12345678
    * 4512345678
    * +4512345678
    White space characters are ignored.

    In addition to validation the module offers generation of valid danish
    phone numbers. The purpose of using generated phone number is up to the
    user, but the original intent is generation of varied sets of test data.

SUBROUTINES AND METHODS
    The following subroutines are to be used in a procedural manner.

  validate($phonenumber)

    This subroutine takes a string and validated whether it is a Danish
    phone number.

    Returns 1 (true) or 0 (false), depending on validity.

  render($phonenumber, $template)

    Returns a phonenumber rendered according to the template parameter or
    the default.

  generate($template, $amount)

    This subroutine takes a string representing a phone number template and
    generates the amount specified by second argument: amount. If no amount
    is specified only a single random phone number is returned.

    The subroutine returns an array, no matter what amount is specified.

  _generate($template)

    This is the actual generating method used by generate.

    It takes a single parameter, a string indicating the template for the
    formatting of the phone numbers to be generated.

    It returns a single random number representing a Danish phone number
    formatted as outlined by the specified template.

  validate_template

    This method is used internally to validate template parameters. Please
    refer to Perl's sprintf for documentation.

DIAGNOSTICS
    * phone number not in recognisable format, the phone number provided to
    the constructor is not parsable. Please evaluate what you are attempting
    to feed to the constructor.
    * phone number parameter is mandatory for the constructor, please
    specify the phone number parameter to the constructor in order to
    continue.
    * template not in recognisable format, the template provided to the
    constructor is not in a parsable format, please evaluate what you
    attempting to feed to the constructor.
CONFIGURATION AND ENVIRONMENT
    No special configuration or environment is necessary.

DEPENDENCIES
    * Carp
    * Exporter
INCOMPATIBILITIES
    No known incompatibilities at this time.

BUGS AND LIMITATIONS
    No known bugs or limitations at this time.

TEST AND QUALITY
    * The
    Perl::Critic::Policy::ValuesAndExpressions::RequireNumberSeparators
    policy has been disabled. We are working with phonenumbers, strings
    consisting primarily of number, so not special interpretation or
    calculative behaviour is needed.
    * Perl::Critic::Policy::ValuesAndExpressions::ProhibitConstantPragma
    policy has been disabled. I like constants.
    * Perl::Critic::Policy::InputOutput::RequireBracedFileHandleWithPrint
    policy has been disabled for now should be revisited at some point.
TODO
    * Please refer to the distribution TODO file
SEE ALSO
    sprintf
        Business::DK::Phonenumber utilizes sprintf to as templating system
        for formatting telephonenumbers. This is a well specified and tested
        interface which is easy to use.

MOTIVATION
    I have been working in Telco for a long time. So validation and
    formatting of telephone numbers is something I have seen at lot of. This
    module is an attempt to sort of consolidate the numerous different
    regular expression solutions I have seen scathered over large code
    bases.
