Phonie¶ ↑

Parsing, validating and creating phone numbers

Install¶ ↑

You can install the phonie library as a gem

gem install phonie

Initializing¶ ↑

You can initialize a new phone object with the number, area code, country code and extension number

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

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

Parsing¶ ↑

You can create a new phone object by parsing from a string. Phonie::Phone does it’s best to detect the country and area codes:

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

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

Phonie::Phone.parse '091/512-5486', country_code: '385'
Phonie::Phone.parse '(091) 512 5486', country_code: '385'

If you feel that it’s tedious, set the default country code once (in your config/environment.rb):

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

Same goes for the area code:

Phonie::Phone.parse '451-588', country_code: '385', area_code: '47'

Alternatively Phonie can be configured via a block

Phonie.configure do |config|
  config.default_country_code = '385'
  config.default_area_code = '47'
  config.add_custom_named_format :short, '%A/%n1-%n2'
end

Phonie::Phone.parse '451-588'

Automatic country and area code detection¶ ↑

Like it’s stated above, Phone does it’s best to automatically detect the country and area code while parsing. To do this, phone uses data stored in data/countries.yml.

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

Validating¶ ↑

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

Phonie::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 Phonie.n1_length), default is 3 (512)
%l - last characters of number (5486)

%x - the extension number

pn = Phonie::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 Phonie::Formatter.

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:

Phonie.configuration.add_custom_named_format :short, '%A/%n1-%n2'
pn.format(:short) # => 091/512-5486

ActiveModel validator¶ ↑

Phonie includes an ActiveModel validator. If you are using ActiveModel you can validate phone numbers like so:

class SomeModel
  include ActiveModel::Validations

  validates :phone_number, phone: true
end

model = SomeModel.new(phone_number: '')
model.valid? # false

model = SomeModel.new(phone_number: '+1 251 123 4567')
model.valid?  # true

How you can contribute¶ ↑

More testing is needed to add support for missing countries, and improve support for tested countries. In many cases only minimal testing is done on area codes, local number formats and number length where more exact matching is possible.

The best places to start is to read through the country tests and data/phone_countries.rb

Other libraries¶ ↑

This is based off a fork of the Phone gem (github.com/carr/phone), and was extensively modified for better support of country detection, and supports far more countries.
