Hello beginners@perl.org,
anyone could me help with:
use strict; use warnings; my %kw = (); my $kw = \%kw; for my $cat (split(/\//, 'something/other/foo/bar')) { $kw->{cnt}++; $kw->{cat${kw->{cnt}}} = $cat }
You don't have to accept the rope Perl will give you to hang yourself,
$kw->{'cat'.$kw->{'cnt'}} = $cat;The special quoting Perl does on hash keys is really only useful for simple strings.
Perl also ignores whitespace for a reason, consider not writing whole programs on one line, it will help you with debugging.
I get: Can't use bareword ("kw") as a HASH ref while "strict refs" in use.. The goal is to get something like: $kw->{cat1} = 'something', $kw->{cat2} = 'other', $kw->{cat3} = 'foo', $kw->{cat4} = 'bar'
anyone?
