JSON_PP(1)             Perl Programmers Reference Guide             JSON_PP(1)

NAME
       json_pp - JSON::PP command utility

SYNOPSIS
           json_pp [-v] [-f from_format] [-t to_format] [-json_opt options_to_json1[,options_to_json2[,...]]]

DESCRIPTION
       json_pp converts between some input and output formats (one of them is
       JSON).  This program was copied from json_xs and modified.

       The default input format is json and the default output format is json
       with pretty option.

OPTIONS
   -f
           -f from_format

       Reads a data in the given format from STDIN.

       Format types:

       json
           as JSON

       eval
           as Perl code

   -t
       Writes a data in the given format to STDOUT.

       null
           no action.

       json
           as JSON

       dumper
           as Data::Dumper

   -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

       Multiple options must be separated by commas:

           Right: -json_opt pretty,canonical

           Wrong: -json_opt pretty -json_opt canonical

   -v
       Verbose option, but currently no action in fact.

   -V
       Prints version and exits.

EXAMPLES
           $ perl -e'print q|{"foo":"","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":"","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}"
                   };
