`{"firstname":John}` [download] Is not valid JSON. If you want to return something that isn't valid JSON, don't use the JSON module. Update: link to jsonlint.com.	[reply] [d/l]

Try something like this (probably a better way to write the regex) `use JSON qw(to_json); $fname = "John"; my %rec_hash = (firstname => $fname); my $json = to_json \%rec_hash; $json =~ s/(.+?\:)\"(\w+)\"/$1$2/g; print "$json\n";` [download]	[reply] [d/l]

Also note that some modules (in various languages) accept a superset of JSON, such that one may accept unquoted strings as values, while another will not. -QM -- Quantum Mechanics: The dreams stuff is made of	[reply]

But, “some languages will accept ...” of course, is never the way that one should go. JSON modules, in various languages, were designed to be universal – and, above all, safe. (JSON started out, in the younger, more naīve days of the Internet, as, “let’s just `eval` the string! ‘Efficient,’ huh?”) Heh. You can afford the couple extra bytes, on whatever platforms and languages you might be using, to use a supplied, standard package to do the work for you. (Especially on the wild-and-wooly JavaScript side!)
