VERSION

version 0.09

SYNOPSIS

Create a class, tag it runnable, and provide a "run" method:

package App::HelloWorld;
use feature 'say';
use Moose;
with 'MooseX::Runnable';
sub run {
my ($self,$name) = @_;
say "Hello, $name.";
return 0; # success
}

Then you can run this class as an application with the included "mx-run" script:

    $ mx-run App::HelloWorld jrockway
    Hello, jrockway.
    $

"MooseX::Runnable" supports MooseX::Getopt, and other similar systems (and is extensible, in case you have written such a system).

DESCRIPTION

MooseX::Runnable is a framework for making classes runnable applications. This role doesn't do anything other than tell the rest of the framework that your class is a runnable application that has a "run" method which accepts arguments and returns the process' exit code.

This is a convention that the community has been using for a while. This role tells the computer that your class uses this convention, and let's the computer abstract away some of the tedium this entails.

REQUIRED METHODS

run

Your class must implement "run". It accepts the command-line args (that were not consumed by another parser, if applicable) and returns an integer representing the UNIX exit value. "return 0" means success.

THINGS YOU GET

mx-run

This is a script that accepts a "MooseX::Runnable" class and tries to run it, using "MooseX::Runnable::Run".

The syntax is:

  mx-run Class::Name
  mx-run <args for mx-run> -- Class::Name <args for Class::Name>

for example:

  mx-run -Ilib App::HelloWorld --args --go --here

or:

  mx-run -Ilib +Persistent --port 8080 -- App::HelloWorld --args --go --here

MooseX::Runnable::Run

If you don't want to invoke your app with "mx-run", you can write a custom version using MooseX::Runnable::Run.

ARCHITECTURE

"MX::Runnable" is designed to be extensible; users can run plugins from the command-line, and application developers can add roles to their class to control behavior.

For example, if you consume MooseX::Getopt, the command-line will be parsed with "MooseX::Getopt". Any recognized args will be used to instantiate your class, and any extra args will be passed to "run".
