That's what the documentation says: ... $json = $json->canonical([$enable]) "If $enable is true (or missing), then the encode method will output JSON objects by sorting their keys. This is adding a comparatively high overhead". ...
So I guess you'd have to use something like that: my $ret_json = JSON::XS->new->canonical()->encode($tmp_hash); -- iD 2012/2/6 Rajeev Prasad <rp.ne...@yahoo.com> > i changed and not getting error anymore but the list is still not > sorted..... > > > my $json = JSON::XS->new; > $json->get_canonical; > $return_json_text = $json->encode ($tmp_hash); > <-------------------no error, but does not produce sorted output > > > the key is a datetime field e.g.: 2012-01-20 22:24:36 value is some > text.... > > > > > ----- Original Message ----- > From: Rajeev Prasad <rp.ne...@yahoo.com> > To: perl list <beginners@perl.org> > Cc: > Sent: Sunday, February 5, 2012 10:20 PM > Subject: Re: need guidance on encode JSON and sorting > > I tried below but getting err: > > my $json = JSON::XS->new; > $json->get_canonical; > $return_json_text = $json->encode $tmp_hash; > > Scalar found where operator expected atscript.pl line 80, near "->encode > $tmp_hash" > > > ??? > > > > > ----- Original Message ----- > From: Rajeev Prasad <rp.ne...@yahoo.com> > To: perl list <beginners@perl.org> > Cc: > Sent: Sunday, February 5, 2012 10:04 PM > Subject: need guidance on encode JSON and sorting > > in the script this is all i am using JSON as: > > ... > use JSON::XS; > ... > .... > $return_json_text = encode_json $tmp_hash; > > this variable ($return_json_text) is then used to display values.
