Handel::Compat::Currency - Price container to do currency conversion/formatting


    use Handel::Compat::Currency;


    my $curr = Handel::Currency->new(1.2);
    print $curr->format();          # 1.20 USD
    print $curr->format('CAD');     # 1.20 CAD
    print $curr->format(undef, 'FMT_SYMBOL');   # $1.20

    print 'Your price in Canadian Dollars is: ';
    print $curr->convert('USD', 'CAD');


The Handel::Currency module provides basic currency formatting within Handel. It can be used separately to format any number into a more friendly format:

    my $price = 1.23;
    my $currency = Handel::Currency->new($price);

    print $currency->format;

A new Handel::Currency object is automatically returned within the shopping cart when calling subtotal, total, and price as an lvalue:

    my $cart = Handel::Cart->search({id => '11111111-1111-1111-1111-111111111111'});

    print $cart->subtotal;              # 12.9
    print $cart->subtotal->format();    # 12.90 USD

By default, a Handel::Currency object will stringify to the original decimal based price.



Arguments: $price [, $code, $formatoptions]

The create a new Handel::Currency instance, simply call new and pass in the price to be formatted:

    my $currency = Handel::Currency->new(10.23);

You can also pass in the default currency code and/or currency format to be used.



Arguments: $code

Gets/sets the three letter currency code for the current currency object.

code throws a Handel::Exception::Argument if code isn't a valid currency code.


Arguments: $from, $to [, $format, $formatoptions]

If no from or formatoptions is specified, the options passed to new and then HandelCurrencyCode and HandelCurrencyFormat will be used instead.

convert throws a Handel::Exception::Argument if from or to aren't valid currency codes.

If format is true, the result of the conversion will also be formatted using the formatting options given or the default in new and then HandelCurrencyFormat.

You can also simply chain the convert call into a format call.

    my $price = Handel::Currency->new(1.25);
    print $price->convert('USD', 'CAD')->format;


Arguments: $converter_class

Gets/sets the converter class to be used when converting currency numbers.


The converter class can be any class that supports the following method signature:

    sub convert {
        my ($self, $price, $from, $to) = @_;

        return $converted_price;

A Handel::Exception exception will be thrown if the specified class can not be loaded.


Arguments: $code [, $options]

Returns the freshly formatted price in a currency and format declared in Locale::Currency::Format. If no currency code or format are specified, the defaults values from new and then Handel::ConfigReader are used. Currently those defaults are USD and FMT_STANDARD.

It is also acceptable to specify different default values. See "CONFIGURATION" and Handel::ConfigReader for further details.

format throws a Handel::Exception::Argument if code isn't a valid currency code.


Arguments $code

Returns the currency name for the specified currency code. If no currency code is specified, the currency code for the current object will be used. If that too is not specified, the code set in HandelCurrencyCode will be used.

name throws a Handel::Exception::Argument if code isn't a valid currency code.


Returns value in scalar context. For now, this returns the same thing that was passed to new. This maybe change in the future.


Returns the original price value given to new. Always use this instead of relying on stringification when deflating currency objects in DBIx::Class schemas.



This sets the default currency code used when no code is passed into format. See Locale::Currency::Format for all available currency codes. The default code is USD.


This sets the default options used to format the price. See Locale::Currency::Format for all available currency codes. The default format used is FMT_STANDARD. Just like in Locale::Currency::Format, you can combine options using |.
