NAME

Data::Printer::Filter::JSON - pretty-print your decoded JSON structures!

VERSION

Version 0.02

SYNOPSIS

# In your program:

use Data::Printer filters => {
    -external => [ 'JSON' ],
};

# or, in your .dataprinter file:

{
    filters => {
        -external => [ 'JSON' ],
    },
};

# You can also tweak the colors:

use Data::Printer {
    filters => {
        -external   => [ 'JSON' ],
    }, color => {
        JSON  => {
          true  => 'bright_blue on_black',
          false => 'black on_bright_blue'
        }
    },
};

DESCRIPTION

Almost every JSON decoder on CPAN handles JavaScript's booleans with objects, and some even reuse them in the resulting data structure. The result? A tiny JSON like this:

{
  "alpha": true,
  "beta" : false,
  "gamma": true,
  "zeta" : false
}

Results in this Data::Printer output:

\ {
    alpha   JSON::XS::Boolean  {
        Parents       JSON::Boolean
        public methods (0)
        private methods (1) : __ANON__
        internals: 1
    },
    beta    JSON::XS::Boolean  {
        Parents       JSON::Boolean
        public methods (0)
        private methods (1) : __ANON__
        internals: 0
    },
    gamma   var{alpha},
    zeta    var{beta}
}

While all I wanted was this:

\ {
    alpha   true,
    beta    false,
    gamma   true,
    zeta    false
}

This module fixes that! :)

Handles

JSON::XS and JSON::PP (JSON 2.x), JSON::NotString (JSON 1.x), JSON::DWIW, JSON::Parser, JSON::SL, Mojo::JSON, boolean (used by Pegex::JSON).

Can't Handle

The ouput of any JSON decoded that doesn NOT use a blessed reference for its booleans, like JSON::Syck or JSON::Streaming::Reader.
