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 indent_length

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.

EXAMPLES

$ perl -e'print q|{"foo":"a~XXa~XX","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":"a~XXa~XX","bar":1234567890000000000000000}|' |\
json_pp -f json -t dumper -json_opt pretty

$VAR1 = {
'bar' => '1234567890000000000000000',
