ProgressbarStream
=================

[](#progressbarstream)

An event-driven progressbar stream that can be added to other streams to show its current progress.

**Table of Contents**

- [Usage](#usage)
    - [data-Event](#data-event)
    - [currentValue-Event](#currentvalue-event)
    - [maximumValue-Event](#maximumvalue-event)
- [Installation](#installation)

Usage
-----

[](#usage)

This stream can be integrate like any other [ReactPHP Stream](https://github.com/reactphp/stream/)

```
$loop = Factory::create();

$progressBarStream = new ProgressbarStream();

$input = new React\Stream\WritableResourceStream(STDOUT, $loop);
$output = new React\Stream\ReadableResourceStream(STDIN, $loop);

$output->pipe($progressBarStream);

$progressBarStream->on('error', function ($errorMessage) {
    echo $errorMessage;
});

$progressBarStream->on('data', function ($progressBarString) use ($input) {
    $input->write($progressBarString . PHP_EOL);
});

$loop->addPeriodicTimer(1, function () use ($output) {
    $output->emit('data', array(1));
});

$loop->addPeriodicTimer(3, function () use ($output) {
    $output->emit('data', array(10));
});

$loop->run();
```

This example will update the progressbar every 1 second by 1 unit/percent and every 3 seconds by 10 units/percent. This example can be found in the [examples folder](/examples).

The progressbar stream will never overflow the maximum value. The stream will end if the current value reaches or goes beyond the maximum value.

### data-Event

[](#data-event)

The `data` event contains the visualization of the progress bar. The data emitted by this event is a string. This event will be emitted if the progressbar is updated.

### currentValue-Event

[](#currentvalue-event)

The `currentValue` event contains the integer value of the current progressbar. This event will be emitted if the progressbar is updated.

### maximumValue-Event

[](#maximumvalue-event)

The `maximumValue` event contains the integer value of the maximum reachable value of the progressbar. This event will be emitted if the progressbar is updated.

Installation
------------

[](#installation)
