NAME

Dist::Zilla::Util::ConfigDumper - Easy implementation of 'dumpconfig'

VERSION

version 0.001000

SYNOPSIS

  ...

  with 'Dist::Zilla::Role::Plugin';
  use Dist::Zilla::Util::ConfigDumper qw( config_dumper );

  around dump_config => config_dumper( __PACKAGE__, qw( foo bar baz ) );

FUNCTIONS

config_dumper

  config_dumper( __PACKAGE__, qw( method list ) );

Returns a function suitable for use with around dump_config.

  my $sub = config_dumper( __PACKAGE__, qw( method list ) );
  around dump_config => $sub;

Or

  around dump_config => sub {
    my ( $orig, $self, @args ) = @_;
    return config_dumper(__PACKAGE__, qw( method list ))->( $orig, $self, @args );
  };

Either way:

  my $function = config_dumper( $package_name_for_config, qw( methods to call on $self ));
  my $hash = $function->( $function_that_returns_a_hash, $instance_to_call_methods_on, @somethinggoeshere );

=~ All of this approximates:

  around dump_config => sub {
    my ( $orig , $self , @args ) = @_;
    my $conf = $self->$orig( @args );
    my $payload = {};

    for my $method ( @methods ) {
      try {
        $payload->{ $method } = $self->$method();
      };
    }
    $config->{+__PACKAGE__} = $payload;
  }

Except with some extra "things dun goofed" handling.
