WordPress Composer Installer

Note: This is extremely work in progress. Do not attempt to run any of this in production environment, unless you are the adventurous type. :)

Install and usage

1. Install dependencies of this plugin first, by running composer install.
2. Activate the plugin in your WordPress install.
3. Copy the sample-plugins-composer.json file and rename it to plugins-composer.json. Add paths to the composer.json files you want to install the dependencies of. (This step will be automated in #3).
4. Click on the Composer install plugin action link in the Plugins screen. This will install the dependencies required for merging the composer.json files.
5. Delete the now generated plugins-composer.lock file (This step will be automated in #2).
6. Click on the Composer install plugin action link again, in the Plugins screen. This will install the dependencies of the plugins specified in the plugins-composer.json file.
7. The dependencies will now be installed in the wp-content/vendor/ directory. You can include the autoloader at wp-content/vendor/autoload.php.

Important bits during development

• Process is really expensive and takes a long time. Probably need to put some kind of wizard, progress bar or whatever and make sure it doesn't time out.
• Of course the plugin needs to be structured properly, this is only a proof of concept for now.
• It needs to hook in on plugin activate/deactivate and do its magic there. Manual option to override.
• Ryan McCue has provided a ton of great UI/UX things to look after in code like this: "How I Would Solve Plugin Dependencies"
