Wrapping all composer vendor packages inside your own namespace. Intended for WordPress plugins.

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)

Install

If you want to hook Imposter into composer command events, install Imposter Plugin instead. See: How can I integrate Imposter with composer?

Installation should be done via composer, details of how to install composer can be found at https://getcomposer.org/.

Config

In your composer.json:

extra.imposter.namespace

Required String

This is the namespace prefix to be added to vendor packages.

extra.imposter.excludes

Optional Array of strings

Vendor packages which needs to be excluded from namespace prefixing. All composer-made packages are excluded by default. Besides, anything under the Composer namespace will be excluded.

Usage

The above snippet:

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

Frequently Asked Questions

How can I integrate imposter with composer?

Use Imposter Plugin instead. It hooks imposter into composer command events.

Does imposter support PSR4, PSR0, Classmap and Files?

Yes for all. PSR-4 and PSR-0 autoloading, classmap generation and files includes are supported.

Can I exclude some of the packages from imposter?

Yes, see extra.imposter.excludes. All composer made packages are excluded by default.

How about require-dev packages?

Imposter do nothing on require-dev packages because imposter is intended for avoiding production environment., not for development environment.

How about PHP built-in classes?

Imposter skips classes that on global namespace, for example: \ArrayObject, \RuntimeException

How about packages that don't use namespaces?

Not for now. Tell me your idea by opening an issue.

How about packages that use fully qualified name?

Not for now. We need a better regex(or something better than regex) in the Transformer class. Tell me your idea by opening an issue

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:

• bring OOP into WordPress
• leveraging development practices from other languages and ecosystems, and applying them to WordPress

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.
