NAME

Hubot::Brain - Represents somewhat persistent storage for the robot.

SYNOPSIS

    $robot->brain->{data}{key} = ''; # scalar
    $robot->brain->{data}{key} = {}; # HashRef
    $robot->brain->{data}{key} = []; # ArrayRef

DESCRIPTION

Brain with external storage like a Hubot::Scrips::redisBrain, value must be a Scalar or HashRef or ArrayRef.

$robot->brain->data will convert to json string and stored to external storage. so, if you trying to store perl object, it will fail.

without external storage, everything is fine to store to memory.

USE EXTERNAL STORAGE

step 1

subscribe brain's save and close event.

step 2

robot boots time, save will emitted. robot shutdown time, close will emitted.

    my $externalStorage = Great::Big::White::World->new;
    $robot->brain->on(
        'save',
        sub {
            my ($e, $data) = @_;
            $externalStorage->save($data);
        }
    );

    $robot->brain->on(
        'close',
        sub {
            $externalStorage->quit;
        }
    );
