NAME

       Number::Phone::Formatters - how to write custom formatters

DESCRIPTION

       How to write custom formatters for phone numbers.

NAMING

       Formatters are modules that live in the "Number::Phone::Formatter::*" namespace. Users
       only need to type the last bit of the name, without the leading
       "Number::Phone::Formatter::", when calling the "format_using" method of Number::Phone.

       The 'E123' formatter name is reserved and implemented by Number::Phone subclasses in their
       "format()" methods.

       The 'FishAndChips' formatter name is reserved because I needed something guaranteed to not
       exist so I could test that it failed correctly.

METHODS

       There is one compulsory method, "format" that you must write. It will be called as a class
       method, with a number in E.123 international format as its only argument, looking
       something like '+CC NNN NNN NNN'. The gory details are at
       <http://www.itu.int/rec/T-REC-E.123/en> but in summary, you'll get:

       a plus sign
       a 1, 2 or 3 digit country code
       whitespace
       a mixture of digits and whitespace

EXAMPLE

       See Number::Phone::Formatter::Raw for an example.
