Dependency graph visualization for composer.json

branch: master
README.md

clue/graph-composer Build Status

Graph visualization for your project's composer.json and its dependencies:

example dependency graph for clue/graph-composer

Usage

Once clue/graph-composer is installed, you can use it via command line like this.

graph-composer show

The show command creates a dependency graph for the given project path and opens the default desktop image viewer for you:

$ php graph-composer.phar show ~/path/to/your/project
  • It accepts an optional argument which is the path to your project directory or composer.json file (defaults to checking the current directory for a composer.json file).

  • You may optionally pass an --format=[svg/svgz/png/jpeg/...] option to set the image type (defaults to svg).

graph-composer export

The export command works very much like the show command, but instead of opening your default image viewer, it will write the resulting graph into an image file:

$ php graph-composer.phar export ~/path/to/your/project
  • It accepts an optional argument which is the path to your project directory or composer.json file (defaults to checking the current directory for a composer.json file).

  • It accepts an additional optional argument which is the path to write the resulting image to. If this argument is not given, it defaults to writing to projectname.svg. Its file extension also sets the image format (unless you also explicitly pass the --format option). Example call:

    $ php graph-composer.phar export ~/path/to/your/project export.png
    
  • You may optionally pass an --format=[svg/svgz/png/jpeg/...] option to set the image type (defaults to svg).

Install

You can grab a copy of clue/graph-composer in either of the following ways.

As a phar (recommended)

You can simply download a pre-compiled and ready-to-use version as a Phar to any directory:

$ wget http://www.lueck.tv/graph-composer/graph-composer.phar

Additionally, you'll have to install GraphViz (dot executable). Users of Debian/Ubuntu-based distributions may simply invoke:

$ sudo apt-get install graphviz

Windows users have to download GraphViZ for Windows and remaining users should install from GraphViz homepage.

If you prefer a global (system-wide) installation without having to type the .phar extension each time, you may simply invoke:

$ chmod 0755 graph-composer.phar
$ sudo mv graph-composer.phar /usr/local/bin/graph-composer`

You can verify everything works by running:

$ graph-composer --version

Updating phar

There's no separate update procedure, simply overwrite the existing phar with the new version downloaded.

Note: Ticket #1 will introduce a self-update command eventually.

Manual Installation from Source

This project requires PHP 5.3+, Composer and GraphViz:

$ sudo apt-get install php5-cli graphviz
$ git clone https://github.com/clue/graph-composer.git
$ cd graph-composer
$ curl -s https://getcomposer.org/installer | php
$ php composer.phar install

If you want to build the above mentioned graph-composer.phar yourself, you have to install clue/phar-composer and can simply invoke:

$ php phar-composer.phar build ~/workspace/graph-composer

Updating manually

$ git pull
$ php composer.phar install

Installation using Composer

Alternatively, you can also install graph-composer as part of your development dependencies. You will likely want to use the require-dev section to exclude graph-composer in your production environment.

This method also requires PHP 5.3+, GraphViz and, of course, Composer.

You can either modify your composer.json manually or run the following command to include the latest tagged release:

$ composer require --dev clue/graph-composer:*

Now you should be able to invoke the following command in your project root:

$ ./vendor/bin/graph-composer show

Updating manually

Just run composer update if you use the dev-master version, otherwise switch to another released version.
