monetize's Introduction

Monetize

A library for converting various objects into Money objects.

Installation

Add this line to your application's Gemfile:

gem 'monetize'

And then execute:

$ bundle

Or install it yourself as:

$ gem install monetize

Usage

Monetize.parse("USD 100") == Money.new(100_00, "USD")
Monetize.parse("EUR 100") == Money.new(100_00, "EUR")
Monetize.parse("GBP 100") == Money.new(100_00, "GBP")

"100".to_money == Money.new(100_00, "USD")

parse will return nil if it is unable to parse the input. Use parse! instead if you want a Monetize::Error (or one of the subclasses) to be raised instead:

>> Monetize.parse('OMG 100')
=> nil

>> Monetize.parse!('OMG 100')
Monetize::ParseError: Unknown currency 'omg'

Optionally, enable the ability to assume the currency from a passed symbol. Otherwise, currency symbols will be ignored, and USD used as the default currency:

Monetize.parse("£100") == Money.new(100_00, "USD")

Monetize.assume_from_symbol = true

Monetize.parse("£100") == Money.new(100_00, "GBP")
"€100".to_money == Money.new(100_00, "EUR")

Monetize can also parse a list of values, returning an array-like object (Monetize::Collection):

Monetize.parse_collection("€80/$100") == [Money.new(80_00, "EUR"), Money.new(100_00, "USD")]
Monetize.parse_collection("€80, $100") == [Money.new(80_00, "EUR"), Money.new(100_00, "USD")]

# The #range? method detects the presence of a hyphen
Monetize.parse_collection("€80-$100").range? == true
