Sirius Invokator is a library that implements a unified way to execute a list of commands/callables that are used by various patterns:

1. middlewares
2. pipelines
3. events
4. command bus (with middleware)
5. actions a la Wordpress
6. filters a la Wordpress

All of the above patterns have in common that they are actually a list of callables, and they differ in the way they are executed in different ways.

In the case of middlewares, the starting parameter (eg: a HTTP request) is passed from one callable to the next, each callable having the option to terminate with a result or call the next callable in the list.

In the case of pipelines, the result of each callable is passed to the next callable and the last callable will return the result of the pipeline

In the case of events, an `event` object is passed through each callable in the list and each callable is independent.

In the case of the command bus, a `command` object is sent to be handled by only one callable.

Elevator pitch
--------------

[](#elevator-pitch)

```
use Sirius\Invokator\Invoker;
use Sirius\Invokator\Callables\CallablePipeline;

$container = app(); // your application DI container
$invoker = new Invoker($container);

$pipeline = new CallablePipeline($invoker);
$pipeline->add('trim')
         ->add('Str::toUppercase')
         ->add(function($value) {
             return $value . '!!!';
         })
         ->add('Logger@info');

$pipeline->run("  hello world  "); // returns `HELLO WORLD!!!`
```
