README

Small library to generate an abstract graph out of an object and its dependencies.

You can then visualize this graph by rendering it with graphviz.

Installation

composer require innmind/object-graph

Usage

use Innmind\ObjectGraph\{
    Lookup,
    Render,
    RewriteLocation\SublimeHandler,
};
use Innmind\OperatingSystem\Factory;
use Innmind\Server\Control\Server\Command;

$lookup = Lookup::of();
$render = Render::of(
    new SublimeHandler, // optional, useful to open the file in Sublime Text instead of the browser
);

$objectGraph = $lookup($theRootObjectOfYourApp); // the object could be the framework instance for example

Factory::build()
    ->control()
    ->processes()
    ->execute(
        Command::foreground('dot')
            ->withShortOption('Tsvg')
            ->withShortOption('o', 'graph.svg')
            ->withInput($render($objectGraph)),
    )
    ->unwrap()
    ->wait();

This will generate a graph.svg file representing the object graph of your application.

Note

This example uses innmind/operating-system to generate the svg file but the package is not a direct dependency, you can use the content returned by $render() however you wish.

Note

You can pass an implementation of RewriteLocation as the first argument of Render so you can rewrite the url to the class file that will be used in the generated graph (useful if you want to generate urls to open the files directly in your IDE).
