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.
