NAME
    Throwable::Factory - lightweight Moo-based exception class factory

SYNOPSIS
       use Throwable::Factory
          GeneralException => undef,
          FileException    => [qw( $filename )],
          NetworkException => [qw( $remote_addr $remote_port )],
       ;
   
       # Just a message...
       #
       GeneralException->throw("Something bad happened");
   
       # Or use named parameters...
       #
       GeneralException->throw(message => "Something awful happened");

       # The message can be a positional parameter, even while the
       # rest are named.
       #
       FileException->throw(
          "Can't open file",
          filename => '/tmp/does-not-exist.txt',
       );

       # Or, they all can be a positional using an arrayref...
       #
       NetworkException->throw(["Timed out", "11.22.33.44", 555]);

DESCRIPTION
    "Throwable::Factory" is an Exception::Class-like exception factory using
    MooX::Struct.

    All exception classes built using "Throwable::Factory" are MooX::Struct
    structs, but will automatically include a "message" attribute, will
    compose the Throwable and StackTrace::Auto roles, and contain the
    following convenience methods:

    "error"
        Read-only alias for the "message" attribute/field.

    "package"
        Get the package for the first frame on the stack trace.

    "file"
        Get the file name for the first frame on the stack trace.

    "line"
        Get the line number for the first frame on the stack trace.

    They provide a "BUILDARGS" method which means that if their constructor
    is called with an odd number of arguments, the first is taken to be the
    message, and the rest named parameters.

    Additionally, the factory can be called with Exception::Class-like
    hashrefs to describe the exception classes. The following two
    definitions are equivalent:

       # MooX::Struct-style
       use Throwable::Factory FooBar => [
          -extends => ['Foo'],
          qw( foo bar ),
       ];
   
       # Exception::Class-style
       use Throwable::Factory FooBar => {
          isa    => 'Foo',
          fields => [qw( foo bar )],
       };

BUGS
    Please report any bugs to
    <http://rt.cpan.org/Dist/Display.html?Queue=Throwable-Factory>.

SEE ALSO
    Exceptions built by this factory inherit from MooX::Struct and compose
    the Throwable and StackTrace::Auto roles.

    This factory is inspired by Exception::Class, and for simple uses should
    be roughly compatible.

    Use Try::Tiny or TryCatch if you need a try/catch mechanism.
