VERSION
version 0.005
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;
DESCRIPTIONRole::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.
