#WPPM ##Composer-based package manager for WordPress This libraries simplifies dependency management for WordPress plugins (and soon themes).

When installed in a WordPress site, a WPPM-enabled plugin will automatically resolve conflicts with other Composer-based plugins.

If a plugin cannot be resolved, the user will be notified that there is a problem and instructed to either disable the plugin or talk to a developer to resolve it manually.

Why is something like WPPM required?

Unless you have a fully composer-enabled WordPress install (eg: roots.io/bedrock), plugins will attempt to load all of their dependencies. When two plugins include the same dependency (different versions), first-to-be-loaded wins.

If one of those plugins is not compatible with the loaded dependency, the site could completely break - or worse (IMO), it could not show any errors until a visitor attempt to do something that uses a missing feature.

How to use

To add Composer support to your plugin, you will need to do the following:

1 - Add hotsource/wppm to your required packages.

2 - Run composer install

3 - Add the following code snippet to autoload your plugin:

require_once __DIR__ . "/vendor/hotsource/wppm/wppm.php";
if ( ! WPPM::autoload( __FILE__ ) )
    return;

Other notes

WPPM::autoload() will return a boolean value indicating whether or not your plugin successfully loaded all dependencies. If it returns false, it's best to simply "return;" as this would prevent your plugin from continuing to load. A notification about the issue will be shown in the WP Admin area.
