Automate plugin processing using hooks and automate ios xcodeproj insertion

[SomaticIT]

Hello,

This PR is linked to issue #46. This PR allows to automatically generates natives bindings for app-settings.json.

To avoid code duplication and optimise build process I rewrote lib/mobile_preferences.js into separated context independent modules and using promises to be compatible with Cordova Hooks:

• lib/filesystem.js: Wrapper for native fs module using promise.
• lib/settings.js: Manage app-settings.json (get, create, remove).
• lib/mappings.js: Contains mapping definitions for each platforms.
• lib/ios.js,lib/android.js: Platform specific modules which expose build and clean methods.

All those modules have dependencies injected, allowing to use Cordova inner require context when using plugin from cli (using hooks) and node.js context when using the plugin from plugman (using build-app-settings.js).

Then I added 3 books :

• after_plugin_add: This hook is executed immediately after plugin installation. It adds a default app-settings.json to application.
• before_plugin_rm: This hook is executed just before plugin uninstallation. It clean every modifications done by the plugin (native code, XML configurations, etc.).
• after_render: This hook is executed immediately after each prepare opérations. It adds Native bindings and XML configuration to platforms projects using app-settings.json configuration.

I also moved existing tests to separates spec definitions in order to keep tests aligned with lib.

Possible Improvements :

• Only build prepared platform during after_render book.
• Easily build new platforms by creating a new independent platform module (eg. build html form for Windows, blackberry, etc.).

Hope you will love it.

I made one mistake and mixed two separate functionalities in one repo — plugin and preference generator. Until Cordova 5.0 this is not a problem because cordova using one repo for modules and you can install generators by running npm. Seems like your PR can handle this problem.

Thanks for merging.

I tested it with Cordova 5.3.3 and it seems to work with both build-app-settings.js and cordova prepare.

One thing I didn't report in my previous comment, I had to replace libxmljs dependency by elementtree which is user by cordova-lib internally.

Thanks.

Did you publish 0.7.2 release ?

[apla]

Yes, you can update via npm. I've already found libxmljs > elementtree migration and it is fine.

Great ! Thanks.

facing a small issue cause of this. if i remove and re-add android platform getting following error -

Error: ENOENT, open 'platforms/android/src/me/apla/cordova/AppPreferencesActivity.java'
    at Error (native)

perhaps moving the hook to before_build might help?

I don't add platform directory to version control. I also do customization on plugins and sometimes need to reset platform directory.
