This seems as if it should be simple, but I've been searching everywhere and can't find an answer.

I inherited a script that used MooseX::Log::Dispatch. It had a setup section that looked like:

has log_dispatch_conf => (
    is => 'ro',
    isa => 'HashRef',
    lazy => 1,
    required => 1,
    default => sub {
      return {
        class => 'Log::Dispatch::File',
        min_level => 'debug',
        filename => $self->config->{mail_log_file},
        mode => '>>',
        newline => 1,
        format => '[%d] [%p] %m at %F line %L%n',
    };
   },
);

I need to do some additional things with this, and no one seems to use this module, so I switched to doing it manually:

has 'logger' => (
    is => 'ro',
    isa => 'Log::Dispatch',
    required => 1,
    lazy => 1,
    default => sub { return
             Log::Dispatch->new(
                 outputs => [
                 [ 'File',
                   min_level => 'debug',
                   filename => $self->config->{mail_log_file},
                   mode => '>>',
                   newline => 1,
                   format => '[%d] [%p] %m at %F line %L%n',
                   ],
# ....

Unfortunately, it seems that Log::Dispatch itself doesn't use the format attribute. And I can't figure out how to apply this. I see there's a configurator module, but I don't want to create an entire configuration file, I just want to get this format into the output. Searching for things like "perl Log Dispatch format" isn't helping. How do I accomplish this?
