NAME Finance::Currency::Convert::GMC - Convert currency using GMC (Golden Money Changer) website VERSION This document describes version 0.007 of Finance::Currency::Convert::GMC (from Perl distribution Finance-Currency-Convert-GMC), released on 2022-02-26. SYNOPSIS use Finance::Currency::Convert::GMC qw(convert_currency); printf "1 USD = Rp %.0f\n", convert_currency(1, 'USD', 'IDR'); DESCRIPTION This module can extract currency rates from the Golden Money Changer website: https://www.gmc.co.id/ Currently only conversions from a few currencies to Indonesian Rupiah (IDR) are available. FUNCTIONS convert_currency Usage: convert_currency($n, $from, $to, $which) -> any Convert currency using GMC. Currently can only handle conversion "to" IDR. Dies if given other currency. Will warn if failed getting currencies from the webpage. Currency rate is not cached (retrieved from the website every time). Employ your own caching. Will return undef if no conversion rate is available for the requested currency. Use "get_currencies()", which actually retrieves and scrapes the source web page, if you need the more complete result. This function is not exported by default, but exportable. Arguments ('*' denotes required arguments): * $from* => *str* * $n* => *float* * $to* => *str* * $which => *str* (default: "sell") Select which rate to use (default is `sell`). Return value: (any) get_currencies Usage: get_currencies() -> [$status_code, $reason, $payload, \%result_meta] Extract data from GMC page. This function is not exported by default, but exportable. No arguments. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) Will return a hash containing key "currencies". The currencies is a hash with currency symbols as keys and prices as values. Tha values is a hash with these keys: "buy" and "sell". HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at .
