#ErrorHandler

Simple module to uniform and ease the management of error calls across a Perl program.

It abstracts an error function so that errors can be handled the same way across all program.

use ErrorHandler;

my $handler = new ErrorHandler;
$handler->fail('Error message');

Settings can be specified during instantiation:

use ErrorHandler;

my $handler = new ErrorHandler({
  mode => 'print'
});

$handler->fail('Error message'); # will print instead of dying

Settings can be specified during instantiation by passing a hash reference to the constructor.

String.

Specifies which method will be used to handle the error. Can be one of die, print, or throw. Default is die.

• die outputs the message and terminates the program.
• print outputs the message and continue as nothing happened.
• throw throws an exception (sets the message in $@ and dies).

Sub.

Specifies a callback sub to be called every time the fail method is invoked.

my $handler = new ErrorHandler({
  fail => sub {
    my $error_message = @_;
    # custom code here...
  }
});

$handler->fail('some error message');

After the callback has been invoked, the fail function will handle the error normally.
