Redaktilo

Redaktilo allows you to find, insert, replace and remove lines using an editor-like object.

Because your code too needs an editor to manipulate files.

Getting started

Use Composer to install Redaktilo in your projects:

composer require "gnugat/redaktilo:~1.0"

Redaktilo provides an Editor class which can be instanciated using EditorFactory:

<?php
require_once __DIR__.'/vendor/autoload.php';

use Gnugat\Redaktilo\EditorFactory;

$editor = EditorFactory::createEditor();

Real life example

For our example, we will create a KernelManipulator similar to the one we can find in SensioGeneratorBundle.

It takes a bundle's fully qualified classname and instert it in the AppKernel file:

<?php

namespace Sensio\Bundle\GeneratorBundle\Manipulator;

use Gnugat\Redaktilo\Editor;

class KernelManipulator extends Manipulator
{
    protected $editor;
    protected $appKernelFilename;

    public function __construct(Editor $editor, $appKernelFilename)
    {
        $this->editor = $editor;
        $this->appKernelFilename = $appKernelFilename;
    }

    public function addBundle($bundle)
    {
        $appKernel = $this->editor->open($this->appKernelFilename);
        $newBundle = "            new $bundle(),";
        if ($this->editor->hasBelow($appKernel, $newBundle)) {
            $message = sprintf('Bundle "%s" is already defined in "AppKernel::registerBundles()".', $bundle);

            throw new \RuntimeException($message);
        }
        $this->editor->jumpBelow($appKernel, '        );');
        $this->editor->insertAbove($appKernel, $newBundle);
        $this->editor->save($appKernel);

        return true;
    }
}

As you can see it's easier to read and to understand than the original PHP token parsing.
