Usage

Indenter

The center of this project is the Indenter class. This class (obviously) indents the incomig stream into an outgoing stream. The Indenter is an EventEmitter and a ReadableStreamInterface. Because this class is a ReadableStreamInterface the indented data will be exposed on the same interface.

To use this data you have to pipe it into another stream, checkout the examples folder.

So what is the reason for this project? This project just shows how awesome the ReactPHP streams are. Streams can come in different sizes: bigger parts, smaller parts, etc. depending on your data source(Downloads, Files, Strings ...). In this project you can be sure a chunk is complete when the new line delimiter comes in, so the next line will be indented. So you can be sure the stream is always correctly indented.

You can find under examples how you can use this project. If you need a file to be indented you can pipe the file into the example.

$ cat words.txt | php examples/indentInput.php

This command can be started on its own.

$ php examples/indentInput.php

This example makes clear why this project should be used. You can indent a whole file with one little example. If you want, you can pipe a command output into this example to see how it works. Just try it.

You can use other indentation methods as the standard 4 spaces e.g. (Tabs, more or fewer spaces) by using it like this

$ cat words.txt | php examples/indentInput.php --tab 

or just add two spaces instead of four:

$ cat words.txt | php examples/indentInput.php --spaces 2

Use it in your production code like this;

$indenter = new Indenter($inputStream);
// or
$indenter = new Indenter($inputStream, $beginningString);

The $beginningString can be any kind of string. Whatever you prefer ;)
