json_pp - JSON::PP command utility

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

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.

    -f from_format

Reads a data in the given format from STDIN.

Format types:

as Perl code

Writes a data in the given format to STDOUT.
no action.
as Data::Dumper

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

Verbose option, but currently no action in fact.

Prints version and exits.

    $ perl -e'print q|{"foo":"XX","bar":1234567890000000000000000}|' |\

                              }, 'Math::BigInt' ),
              'foo' => "\x{3042}\x{3044}"
