### Shared data transfer interfaces for PHP

[](#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
------------

[](#installation)

This package requires PHP 8.4 or higher.

Install via Composer:

```
composer require decodelabs/deliverance
```

Usage
-----

[](#usage)

### Channels

[](#channels)

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

```
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

[](#io-broker)

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

```
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->readBlocking = 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()`.
