Another Way To Do It - an array_ref of hashes:
$countryMap = [
{
shortcountry => 'US',
country => 'USA',
currency => 'USD',
},
{
shortcountry => 'D',
country => 'Germany',
currency => 'DM',
},
....
];
This is basically a flatfile db in memory - and can be easily saved to a file using
Data::Dumper. The problem is getting the data out. I don't see a single step way to do this, but hey, we're optimising for developer time here, not cpu / memory. I'd do
sub getem {
my $data = shift;
my $find = shift;
my $in = shift;
my $return = shift;
for (@$data) {
if ($_->{$in} eq $find) {
return $_->{$return};
}
}
}
Then to find 'US' with 'USA',
my $result = getem($countryMap,'US','country','shortcountry');

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
