はてブのWeb Hookで指定したタグが含まれていたらメールする

のを軽く作ってみた。

#!/usr/bin/env perl

has 'to' => (is => 'rw', isa => 'MailAddr', default => '[email protected]');
has 'subject' => (is => 'rw', isa => 'Str', required => 1);
has 'body' => (is => 'rw', isa => 'Str', required => 1);

sub run {
  my $self = shift;
  my $mail = Email::MIME->create(
      header => [
	  From => $self->from,
	  To => $self->to,
	  Subject => Encode::encode('MIME-Header-ISO_2022_JP', $self->subject),
      ],
      parts => [
	  encode('iso-2022-jp', $self->body),
      ],
  );
  my $sender = Email::Send->new( { mailer => 'Sendmail' } );
  $sender->send($mail);
}

__PACKAGE__->meta->make_immutable;

package main;

my $target_tag = 'tag';
