Data::Dump for perl6

that's right folks, here's a quicky for your data dump needs. if you have Term::ANSIColor installed then the output will be so colorful your eyes might bleed.

feel free to submit bugs or make suggestions, if you submit a bug please provide a concise example that replicates the problem and i'll add some tests and make this thing better.

options

• indent

default: 2

perl6
    <...>
    say Dump({ some => object }, :indent(4));
    <...>

• max-recursion

default: 50

perl6
    <...>
    say Dump({ some => object }, :max-recursion(3));
    <...>

• color

default: True

This will override the default decision to use color on the output if Term::ANSIColor is installed. Passing a value of False will ensure that the output is vanilla.

perl6
    <...>
    say Dump({ some => object }, :color(False));
    <...>

gist

default: False

This will override the default object determination and output and use the output of .gist

perl6
 <...>
 say Dump({ some => object }, :gist);
 <...>

no-postfix

default: False

This will shorten Str|Int|Rat|Numeric output from 5.Int|"H".Str to simply 5|"H"

skip-methods

default: False

This will skip the methods if you dump custom classes.

overrides

default: {}

This will allow you to override how DD dumps certain types of objects.

perl6
 Dump($object, overrides => {
   Int => sub ($int) { return $int * 2; },
   Str => sub ($str) { return "'$str'"; },
   # etc.
 });

usage

use Data::Dump;

say Dump(%(
      key1 => 'value1',
      key256 => 1,
    ));

output:

{
      key1   => "value1".Str,
      key256 => 1.Int,
    }

note: if you have Term::ANSIColor installed then it's going to be amazing. so, prepare yourself.

oh you want to Dump your custom class?

here you go, dude

use Data::Dump;

class E {
      has $.public;
      has Int $!private = 5;
      method r(Str $a) { };
      method s($b, :$named? = 5) { };
      method e returns Int { say $!private; };
    };

say Dump(E.new);

output:

E :: (
      $!private => 5.Int,
      $!public  => (Any),

method e () returns Int {...},
      method public () returns Mu {...},
      method r (Str $a) returns Mu {...},
      method s (Any $b, Any :named($named) = 5) returns Mu {...},
    )
