This program was copied from L<json_xs> and modified. The default input format is json and the default output format is json with pretty option. =head1 OPTIONS =head2 -f -f from_format Reads a data in the given format from STDIN. Format types: =over =item json as JSON =item eval as Perl code =back =head2 -t Writes a data in the given format to STDOUT. =over =item null no action. =item json as JSON =item dumper as Data::Dumper =back =head2 -json_opt options to JSON::PP Acceptable options are: ascii latin1 utf8 pretty indent space_before space_after relaxed canonical allow_nonref allow_singlequote allow_barekey allow_bignum loose escape_slash indent_length Multiple options must be separated by commas: Right: -json_opt pretty,canonical Wrong: -json_opt pretty -json_opt canonical =head2 -v Verbose option, but currently no action in fact. =head2 -V Prints version and exits. =head1 EXAMPLES $ perl -e'print q|{"foo":"あい","bar":1234567890000000000000000}|' |\ json_pp -f json -t dumper -json_opt pretty,utf8,allow_bignum $VAR1 = { 'bar' => bless( { 'value' => [ '0000000', '0000000', '5678900', '1234' ], 'sign' => '+' }, 'Math::BigInt' ), 'foo' => "\x{3042}\x{3044}" }; $ perl -e'print q|{"foo":"あい","bar":1234567890000000000000000}|' |\ json_pp -f json -t dumper -json_opt pretty $VAR1 = { 'bar' => '1234567890000000000000000', 'foo' => "\x{e3}\x{81}\x{82}\x{e3}\x{81}\x{84}" }; =head1 SEE ALSO L<JSON::PP>, L<json_xs> =head1 AUTHOR Makamaka Hannyaharamitu, E<lt>makamaka[at]cpan.orgE<gt> =head1 COPYRIGHT AND LICENSE Copyright 2010 by Makamaka Hannyaharamitu This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself. =cut
