Wrapping all composer vendor packages inside your own namespace. Intended for WordPress plugins. Imposter Plugin is a composer plugin wrapper for Imposter.

Why?

Because of the lack of dependency management in WordPress, if two plugins bundled conflicting versions of the same package, hard-to-reproduce bugs arise. Monkey patching composer vendor packages, wrapping them inside your own namespace is a less-than-ideal solution to avoid such conflicts.

• A Narrative of Using Composer in a WordPress Plugin
• A Warning About Using Composer With WordPress
• Plugin Dependencies (Yet Another Plugin Dependencies Ticket)

Usage

Sit Back and Relax

Once installed, this plugin hooks into composer install, composer update and composer dump-autoload, automatically run imposter for you. Besides, imposter plugin autoloads all modified files as classmap.

When those events triggered, this plugin:

1. looks for /path/to/project/root/composer.json
2. finds out vendor-dir
3. finds out all required packages, including those required by dependencies
4. finds out all autoload paths for all required packages
5. prefixes all namespaces with the imposter-plugin namespace defined in your composer.json

How to install impostified plugins via composer?

Impostified plugins are meant to be commited to wp.org svn.

Using imposter means you forgo the ability to install the plugins with composer directly via packagist.org or VCS (even with type: wordpress-plugin in composer.json).

To composer require impostified plugins, use wpackagist.org.

The whole imposter situation is horrible. What can we do about it?

Until WordPress core comes up with a solution on dependency managment, keep clam and carry on.

In the meantime, checkout these tools to make WordPress suck less modernizing WordPress development:

Which composer versions are supported?

Both v1 and v2.

Will you add support for older PHP versions?

Never! This plugin will only work on actively supported PHP versions.

Don't use it on end of life or security fixes only PHP versions.
