This is my previous function rewritten to handle spaces in the data by escaping them. Other surprises may be handled similarly.
#!/usr/bin/perl
use Data::Dumper;
sub hoa2aoh {
my $hoa = shift;
my @keys = keys %$hoa;
my @patterns = map {
local $" = ',';
"{@{[map {s/ /\\ /g; $_} @$_]}}";
} values %$hoa;
[
map {
my %hash;
@hash{@keys} = split ',';
\%hash;
} glob join ',', @patterns
];
}
my $HoA = {
'1,2,flintstones' => [ 'fred-1 foo-2', 'barney-1 bar-2' ],
'2,3,jetsons' => [ 'george-1 foo-2', 'jane-1 bar-2'],
};
print Dumper hoa2aoh($HoA);
__END__
$VAR1 = [
{
'1,2,flintstones' => 'fred-1 foo-2',
'2,3,jetsons' => 'george-1 foo-2'
},
{
'1,2,flintstones' => 'barney-1 bar-2',
'2,3,jetsons' => 'george-1 foo-2'
},
{
'1,2,flintstones' => 'fred-1 foo-2',
'2,3,jetsons' => 'jane-1 bar-2'
},
{
'1,2,flintstones' => 'barney-1 bar-2',
'2,3,jetsons' => 'jane-1 bar-2'
}
];

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).
