NAME

Role::HasMessage::Errf - a thing with a String::Errf-powered message

CONTENTS

VERSION

version 0.006

SYNOPSIS

In your class...



  package Errfy;
  use Moose;

  with Role::HasMessage::Errf;

  has payload => (
    is  => ro,
    isa => HashRef,
    required => 1,
  );



Then...



  my $thing = Errfy->new({
    message => "%{error_count;error}n encountered at %{when}t",
    payload => {
      error_count => 2,
      when        => time,
    },
  });

  # prints: 2 errors encountered at 2010-10-20 19:23:42
  print $thing->message;



DESCRIPTION

Role::HasMessage::Errf is an implementation of Role::HasMessage that uses String::Errf to format sprintf-like message strings. It adds a message_fmt attribute, initialized by the message argument. The value should be a String::Errf format string.

When the provided message method is called, it will fill in the format string with the hashref returned by calling the payload method, which must be implemented by the including class.

Role::HasMessage::Errf is a parameterized role. The default parameter lets you set a default format string or callback. The lazy parameter sets whether or not the message_fmt attribute is lazy. Setting it lazy will require that a default is provided.
