DESCRIPTION
Using Finance.Yahoo.com, converts a sum between two currencies.
USE
Call the module's &convert
routine, supplying three arguments: the amount to convert, and the currencies to convert from and to.
Codes are used to identify currencies: you may view them in the values of the %currencies
hash, where keys are descriptions of the currencies.
In the event that attempts to convert fail, you will recieve undef
in response, with errors going to STDERR, and notes displayed if the modules global $CHAT
is defined.
SUBROUTINE convert
$value = &convert( $amount_to_convert, $from, $to);
Requires the sum to convert, and two symbols to represent the source and target currencies.
In more detail, access http://finance.yahoo.com/d/quotes.csv?s=GBPEUR=X&f=l1, where the value of s
(in the example, GBPUSD
) is the value of the source and target currencies, and the rest is stuff I've not looked into....
DEPRECATED SUBROUTINE deprecated_convert
The old convert
routine: accesses http://finance.yahoo.com/m5?a=amount&s=start&t=to
, where start
is the currency being converted, to
is the target currency, and amount
is the amount being converted. The latter is a number; the former two codes defined in our %currencies
hash. (For the date this was last checked, print $DATE
).
EXPORTS
None.
REVISIONS
Please see the enclosed file CHANGES.
PROBLEMS?
If this doesn't work, Yahoo have probably changed their URI or HTML format. Let me know and I'll fix the code. Or by all means send a patch. Please don't just post a bad review on CPAN, I don't get CC'd them.
