It is written by Marc Lehmann in C, so must be compiled and
installed in the used environment.
JSON::PP is a pure-Perl module and has compatibility to JSON::XS.
=head2 FEATURES
=over
=item * correct unicode handling
This module knows how to handle Unicode (depending on Perl version).
See to L<JSON::XS/A FEW NOTES ON UNICODE AND PERL> and L<UNICODE HANDLING ON PERLS>.
=item * round-trip integrity
When you serialise a perl data structure using only data types supported
by JSON and Perl, the deserialised data structure is identical on the Perl
lib/App/cpanminus/fatscript.pm view on Meta::CPAN
open( my $fh, '<', 'json.data' );
$json_text = <$fh>;
$perl_scalar = decode_json( $json_text );
If an outer data is not encoded in UTF-8, firstly you should C<decode> it.
use Encode;
local $/;
open( my $fh, '<', 'json.data' );
my $encoding = 'cp932';
my $unicode_json_text = decode( $encoding, <$fh> ); # UNICODE
# or you can write the below code.
#
# open( my $fh, "<:encoding($encoding)", 'json.data' );
# $unicode_json_text = <$fh>;
In this case, C<$unicode_json_text> is of course UNICODE string.
So you B<cannot> use C<decode_json> nor C<JSON> module object with C<utf8> enable.
Instead of them, you use C<JSON> module object with C<utf8> disable.
$perl_scalar = $json->utf8(0)->decode( $unicode_json_text );
Or C<encode 'utf8'> and C<decode_json>:
$perl_scalar = decode_json( encode( 'utf8', $unicode_json_text ) );
# this way is not efficient.
And now, you want to convert your C<$perl_scalar> into JSON data and
send it to an outer world - a network or a file content, and so on.
Your data usually contains UNICODE strings and you want the converted data to be encoded
in UTF-8, you should use C<encode_json> or C<JSON> module object with C<utf8> enable.
print encode_json( $perl_scalar ); # to a network? file? or display?
# or
print $json->utf8->encode( $perl_scalar );
If C<$perl_scalar> does not contain UNICODE but C<$encoding>-encoded strings
for some reason, then its characters are regarded as B<latin1> for perl
(because it does not concern with your $encoding).
You B<cannot> use C<encode_json> nor C<JSON> module object with C<utf8> enable.
Instead of them, you use C<JSON> module object with C<utf8> disable.
Note that the resulted text is a UNICODE string but no problem to print it.
# $perl_scalar contains $encoding encoded string values
$unicode_json_text = $json->utf8(0)->encode( $perl_scalar );
# $unicode_json_text consists of characters less than 0x100
print $unicode_json_text;
Or C<decode $encoding> all string values and C<encode_json>:
$perl_scalar->{ foo } = decode( $encoding, $perl_scalar->{ foo } );
# ... do it to each string values, then encode_json
$json_text = encode_json( $perl_scalar );
This method is a proper way but probably not efficient.
See to L<Encode>, L<perluniintro>.
lib/App/cpanminus/fatscript.pm view on Meta::CPAN
so JSON::PP wraps the C<join> with a subroutine. Thus JSON::PP works slow in the versions.
=head2 Perl 5.6
Perl can handle Unicode and the JSON::PP de/encode methods also work.
=head2 Perl 5.005
Perl 5.005 is a byte sementics world -- all strings are sequences of bytes.
That means the unicode handling is not available.
In encoding,
$json->allow_nonref->encode(chr hex 3042); # hex 3042 is 12354.
$json->allow_nonref->encode(chr hex 12345); # hex 12345 is 74565.
Returns C<B> and C<E>, as C<chr> takes a value more than 255, it treats
as C<$value % 256>, so the above codes are equivalent to :
$json->allow_nonref->encode(chr 66);
