Dearest Monks,
Let's say I've got an array of hashes like this:
@AoH =
(
{ name => Adam, age => 0 },
{ name => Bob, age => 10 },
{ name => Cat, age => 20 }
);
and I want to produce a 'quoted' comma separated list (a bit like CSV) of the names, i.e.:
'Adam','Bob','Cat'
can anyone offer more concise/efficient/elegant ways of doing it than this kind of approach, which does work, and is pretty concise, but ain't pretty:
$csv .= ",'$AoH[$_]{name}'" for (0..$#AoH);
$csv =~ s/^,//;
Order of names doesn't matter.
Update: If there are no names (i.e. @AoH is empty), the output should be:
''
i.e. 2 single quotes, but my solution above doesn't meet that requirement (I've replied to Rolf below with some which do, though).
Thanks.
