### Shared data transfer interfaces for PHP

Deliverance is a middleware library intended to be used by other framework systems that need to manage multiplex IO operations.

---

## Installation

Install via Composer:

```bash

composer require decodelabs/deliverance

```

## Usage

### Channels

Channels represent simple in / out handlers and can be written to and read from:

```php

use DecodeLabs\Deliverance;

$stream = Deliverance::openStream('path/to/file');

$stream->writeLine('Hello world');

$stream = Deliverance::openCliOutputStream(); // Same as new Deliverance\Channel\Stream(STDOUT);

$buffer = Deliverance::newBuffer();

$buffer->write('Some text to buffer');

echo $buffer->read(6); // "Some t"

```

### IO Broker

Channels can be grouped together and managed by an IO Broker -

```php

use DecodeLabs\Deliverance;

// Create a CLI IO handler

$broker = Deliverance::newBroker()

    ->addInputProvider(Deliverance::openStream(STDIN))

    ->addOutputReceiver(Deliverance::openStream(STDOUT))

    ->addErrorReceiver(Deliverance::openStream(STDERR));

// Shortcut to the above:

$broker = Deliverance::newCliBroker();

// Read line from CLI

$broker->setReadBlocking(true);

$text = $broker->readLine();

// Write it back to output

$broker->writeLine('INPUT: '.$text);

```

Once grouped, the Channels in an IO broker can be used as the interface between many different information sources; see [Systemic Unix process launcher](https://github.com/decodelabs/systemic/blob/develop/src/Systemic/Process/Launcher/Unix.php) for an example of an IO Broker managing input and output with proc_open().
