Manual Usage

You can obtain a TelephoneNumber object by calling:

phone_object = TelephoneNumber.parse("3175082237", :us) ==>

#

After that you have the following instance methods available to you.

• valid_types

  Returns all types that the number is considered valid for.

  phone_object.valid_types ==> [:fixed_line, :mobile, :toll_free]

• valid?

  Returns boolean value indicating whether or not valid_types is empty.

  phone_object.valid? ==> true

• national_number(formatted: true)

  Returns the national formatted number including special characters such as parenthesis and dashes. You can omit the special characters by passing formatted: false

  phone_object.national_number ==> "(317) 508-2237"

• international_number(formatted: true)

  Returns the international formatted number including special characters such as parenthesis and dashes. You can omit the special characters by passing formatted: false

  phone_object.international_number ==> "+1 317-508-2237"

• e164_number(formatted: true)

  Returns the international formatted number including special characters such as parenthesis and dashes. You can omit the special characters by passing formatted: false

  phone_object.e164_number ==> "+13175082237"

• country

  Returns an object containing data related a the number's country.

…

TelephoneNumber.valid?("3175082237", :US, [:mobile, :fixed_line]) ==> true
TelephoneNumber.valid?("3175082237", :US, [:toll_free]) ==> false
```

• invalid?

  Returns boolean value indicating whether or not a particular number is invalid.

  TelephoneNumber.invalid?("3175082237", :US) ==> false

  If you are looking to invalidate against a specific set of keys, you can pass in an array of keys

  TelephoneNumber.invalid?("3175082237", :US, [:mobile, :fixed_line]) ==> false
  TelephoneNumber.invalid?("3175082237", :US, [:toll_free]) ==> true
  

…

TelephoneNumber.default_format_pattern = "(\d{3})(\d{3})(\d*)" TelephoneNumber.default_format_string = "($1) $2-$3"

invalid_number = "1111111111" phone_object = TelephoneNumber.parse(invalid_number, :US) phone_object.national_number ==> "(111) 111-1111"

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

While developing new functionality, you may want to test against specific phone numbers. In order to do this, add the number to `lib/telephone_number/test_data_generator.rb` and then run `rake data:test:import`. This command will reach out to the demo application provided by Google and pull the correct formats to test against.

To install this gem onto your local machine, run `bundle exec rake install`.
