in reply to How to create a hash from string

Both given answers are fine, but this smells like records embedded in CSV, where both answers will soon fail. What if x is allowed to be This, my friend, is why : is allowed in "text" to fail?

update: additional remarks:

In case that cannot happen, stick to the earlier answer. They are fast and simple. In case it /can/ happen, you need a double CSV parser. The first to split on , the second on ::

my $outer = Text::CSV_XS->new ({ binary => 1, auto_diag => 1 }); my $inner = Text::CSV_XS->new ({ binary => 1, auto_diag => 1, sep_char + => ":" }); my %hash; while (my $row = $outer->getline ($fh)) { foreach (@$row) { $inner->parse ($_); my @f = $inner->fields; if (@f >= 2) { # assuming key:value:1 will result in $hash{key +} = "value:1" my $key = shift @f; $hash{$key} = join ":" => @f; } else { warn "Probably not a key-value pair '$_'"; } } }

which is likely to get more and more complicated as you proceed.


Enjoy, Have FUN! H.Merijn
