Dear Monks,
I have a snippet of code:
use strict;
use warnings;
use DBI;
use Data::Dumper;
use IO::Prompt;
use PDF::Reuse;
my $choice = prompt 'Please choose your report output format...', -1,
-menu => [ 'Console', 'PDF', 'HTML', 'Quit', ];
print "You chose: [$choice]\n\n";
my $action_ref = {
'Console' => \&print_console,
'PDF' => \&generate_pdf,
'HTML' => \&generate_html,
'Quit' => sub { print "Exiting...\n"; exit 0; }
};
if ( $action_ref->{$choice} ) { $action_ref->{$choice}->(); }
else { warn "Unknown option: '$choice';\n" }
Why does print Dumper($action_ref); give:
$VAR1 = {
'HTML' => sub { "DUMMY" },
'Quit' => sub { "DUMMY" },
'Console' => sub { "DUMMY" },
'PDF' => sub { "DUMMY" }
};
and not what's actually in the subs, which are further down the program?
A simple pointer to the docs I missed will do ;-)
Thanks,
Gavin.

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).

are good places to start.
