This documentation is for the unreleased development branch.

Current release: 1.3.0.beta1
Current stable: 1.2.3

Description

Ruby library for phone number parsing, validation, and formatting.

Features

Automatic country and area code detection

Phone does its best to automatically detect the country and area code while parsing. To do this, phone uses data stored in data/phone/countries.yml.

Each country code can have a regular expression named area_code that describes what the area code for that particular country looks like.

If an area_code regular expression isn't specified, the default, Phoner::Phone::DEFAULT_AREA_CODE (correct for the US) is used.

Validating

Validating is very relaxed, basically it strips out everything that's not a number or '+' character:

Phoner::Phone.valid? 'blabla 091/512-5486 blabla'

Formatting

Formating is done via the #format method. The method accepts a Symbol or a String.

When given a string, it interpolates the string with the following fields:

%c - country_code (385)
%a - area_code (91)
%A - area_code with leading zero (091)
%n - number (5125486)
%f - first @@n1_length characters of number (configured through Phoner::Phone.n1_length), default is 3 (512)
%l - last characters of number (5486)
%x - the extension number

pn = Phoner::Phone.parse('+385915125486')
pn.to_s # => "+385915125486"
pn.format("%A/%f-%l") # => "091/512-5486"
pn.format("+ %c (%a) %n") # => "+ 385 (91) 5125486"

When given a symbol it is used as a lookup for the format in the Phoner::Phone.named_formats hash.

pn.format(:europe) # => "+385 (0) 91 512 5486"
pn.format(:us) # => "(234) 123-4567"
pn.format(:default_with_extension) # => "+3851234567x143"

You can add your own custom named formats like so:

Phoner::Phone.named_formats[:short] = '%A/%n1-%n2'
pn.format(:short) # => 091/512-5486

Finding countries by their isocode

If you don't have the country code, but you know from other sources what country a phone is from, you can retrieve the country using the country isocode (such as 'de', 'es', 'us', ...). Remember to call Phoner::Country.load before using this lookup.

if country = Phoner::Country.find_by_country_isocode(user_country_isocode)
  phone_number = Phoner::Phone.parse(user_input, :country_code => country.country_code)
end

Examples

require 'phone'

Initializing

Initialize a new phone object with the number, area code, country code and extension number:

Phoner::Phone.new('5125486', '91', '385')

Phoner::Phone.new(:number => '5125486', :area_code => '91', :country_code => '385', :extension => '143')

Parsing

Create a new phone object by parsing from a string. Phoner::Phone does it's best to detect the country and area codes:

Phoner::Phone.parse '+385915125486'
Phoner::Phone.parse '00385915125486'

If the country or area code isn't given in the string, you must set it, otherwise it doesn't work:

Phoner::Phone.parse '091/512-5486', :country_code => '385'
Phoner::Phone.parse '(091) 512 5486', :country_code => '385'

If you feel that it's tedious, set the default country code once:

Phoner::Phone.default_country_code = '385'
Phoner::Phone.parse '091/512-5486'
Phoner::Phone.parse '(091) 512 5486'

Same goes for the area code:

Phoner::Phone.parse '451-588', :country_code => '385', :area_code => '47'

Phoner::Phone.default_country_code = '385'
Phoner::Phone.default_area_code = '47'

Phoner::Phone.parse '451-588'
