Introduction

Phone numbers as data: validate, inspect, search, generate.

Phone-number on Clojars Phone-number on cljdoc CircleCI

A pragmatic, data-oriented Clojure wrapper around Google’s Libphonenumber for validating, inspecting, formatting, searching text, and generating phone numbers. It treats phone numbers as data: most functions accept strings, numbers, PhoneNumber instances, or keyword-keyed maps, and return values that are pleasant to pipe through.

Features

  • Data-first, polymorphic API: phone numbers can be expressed as numbers, strings, PhoneNumber objects, or maps.

  • Rich, keyword-keyed info maps with optional namespace inference (e.g. a key can be :phone-number/type or just :type; a type can be :phone-number.type/mobile or just :mobile).

  • Optional enrichment with carrier, location, and time zone data (via libphonenumber add-on modules), exposed through the same data-first API.

  • Stable options-map API for text searching (phone-number.core/find-numbers-opts), backed by lazy maps (LazyMap) so expensive info can be computed on demand.

  • Built-in support for short numbers (e.g. emergency numbers): validation, reachability, and expected cost class.

  • Sample generation that returns both the PhoneNumber and reproducibility/debug data (including :phone-number.sample/random-seed and sampler stats).

  • Specs with generators for generative testing, plus structured errors via ex-info with :phone-number/error in ex-data.

Caveats

If your program processes a lot of phone numbers and your strategy is to keep them in a native format (a result of calling phone-number.core/number), then be aware that, by default, all created PhoneNumber objects will have their raw input stored internally. This affects comparison in a way that the object representing a number +442920183133 will not be equal to the object representing the same number but with spaces (+44 2920 183 133). This is because the equality test is based, among other things, on raw input values, which are also used to generate each object’s hash code.

To work around this, you have two options:

  • Use phone-number.core/number-noraw on input data to parse numbers without preserving raw inputs.

  • Use phone-number.core/number-noraw on existing objects to create raw-input-free copies.

Optionally, phone-number.core/number-optraw can also be used (especially in processing pipelines) to preserve raw input only when the created object is initialized from an existing one (an instance of PhoneNumber). For other argument types, the protocol method behaves like number-noraw.

Some functions validate their arguments and may throw clojure.lang.ExceptionInfo on invalid inputs. Such exceptions include :phone-number/error in ex-data, which can be used for error classification.

Sneak peeks

  • It can show information about phone numbers:
(require '[phone-number.core :as phone])

;; region taken from a phone number

     first
     (into {}) ;; materialize lazy-map (also forces :phone-number/info)
     (dissoc :phone-number/number))
