If I numerically sort a set of data like:
my @data = (
{ foo: 22, bar: 128 },
{ foo: 22, bar: 23 },
);
....in Template Toolkit using the following:
[% data.nsort('foo', 'bar') %]
....what TT will return is a sort on these strings:
22/*^UNLIKELY^*/128
22/*^UNLIKELY^*/23
....which will not match the desired behavior of numerically sorting.
To fix:
Instead of making a single sort key, have it iterate through the fields
thus when sorting:
sub list_nsort {
my ($list, @fields) = @_;
return $list unless @$list > 1; # no need to sort 1 item lists
return [
@fields
? sort { first { $a->{$_} <=> $b->{$_} } @fields }
@$list
: sort { $a <=> $b }
@$list,
];
}
(In fact, might this be a better way to sort alphanumerically as well?)
