A library for converting various objects into Money objects.
Run:
bundle add monetize
Or install it yourself as:
$ gem install monetize
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")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")Parsing can be improved where the input is not expected to contain fractional subunits.
To do this, set Monetize.expect_whole_subunits = true
Monetize.parse('EUR 10,000') == Money.new(100_00, "EUR")
Monetize.expect_whole_subunits = true
Monetize.parse('EUR 10,000') == Money.new(10_000_00, "EUR")Why does this work? If we expect fractional subunits then the parser will treat a single delimiter as a decimal marker if it matches the currency's decimal marker. But often this is not the case - a European site will show $10.000 because that's the local format. As a human, if this was a stock ticker we might expect fractional cents. If it's a retail price we know it's actually an incorrect thousands separator.
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? == trueSee CONTRIBUTING.md for details.
