Coverage Status

Phony

Disclaimer: Phony works with international numbers only, such as 61 412 345 678!

The (admittedly crazy) goal of this Gem is to be able to normalize/format/split all phone numbers in the world.

Used in: airbnb.com, socialcam.com, zendesk.com (and many, many others).

Runtime Memory Usage

According to memory_profiler, the Phony gem uses roughly 1MB of memory per Ruby process. Usage was generated using (look for Total retained): ruby -e 'require "memory_profiler"; MemoryProfiler.report(allow_files: "phony"){ require "phony" }.pretty_print'

Description

This gem normalizes, formats and splits E164 phone numbers. A valid E164 phone number must include a country code.

E164 numbers are international numbers with a country dial prefix, usually an area code and a subscriber number. For example, the Australian number +61 412 345 678 can be broken down into the following components:

  • Country Code (CC): a country code of 61
  • National Destination Code (NDC): a mobile number denoted by the 4 (specific to Australia)
  • Local Number Part: a subscriber number of 12 345 678

It currently handles the countries listed at the end of this README.

It is covered by roughly 2,250 tests that run in 2 seconds (April 2019). If it doesn’t work, please enter an issue or better, fork and send a pull request.

Usage docs

Phony uses qed as docs and to run its functional tests. Start here for usage docs: Usage index.

Phony.normalize(number)

Normalize intelligently removes all non-numeric characters of a number. Do it before storing a number in a DB.

Phony.normalize docs

Phony.normalize('1-888-407-4747').assert == '18884074747'

Phony.format(number, options = {})

Format formats a normalized number according to a country’s predominant formatting. Lots of options for int’l, national, local formatting.

Phony.format docs

Phony.format('41443643532').assert == '+41 44 364 35 32'

Phony.plausible?(number, options = {})

Is a number plausible?

Phony.plausible? docs

Phony.assert.plausible?('+41 44 111 22 33')

Phony.split(number)

Split a number into its parts: CC, NDC, local.

Phony.split docs

Phony.split('3928061371').assert == ['39', '2', '806', '1371']

NB If a country does not have an NDC, #split will return false in the NDC position, for example for Denmark:

Phony.split('4512121212').assert == ['45', false, '12', '12', '12', '12']

Loading only a country subset (Phony 2.18.0+).

Use this in case you’d like to save memory that is used by Phony’s CC rules.

Phony::Config.load docs

First, require 'phony/config'. Then, one of the following, which will load the rest of Phony.

Load only these CCs: Phony::Config.load(only: ['41', '44'])

Loads everything except these CCs: Phony::Config.load(except: ['41', '44'])

Convenience form of only: Phony::Config.load('41', '44')

Each of these loads the rest of Phony.

Memory usage can be checked using (look for Total retained): ruby -e 'require "memory_profiler"; MemoryProfiler.report(allow_files: "phony"){ require "phony/config"; Phony::Config.load("1") }.pretty_print' For example, when just loading the NANP CC, the retained memory usage is ~63kB.
