Framework Breaking Changes

Facades have been removed entirely. While very convenient to use, facade classes ultimately made having multiple WP Emerge instances running alongside each other impossible.
Accessing your various services statically is now done via an App class.
Refer to the updated documentation to learn where this new app class comes from.
- Application is now \App.
- Csrf is now \App::csrf().
- Flash is now \App::flash().
- OldInput is now \App::oldInput().
- Response is now \App::responses().
- Route is now \App::route().
- View is now \App::views().
- ViewEngine has been removed – pass it as a constructor dependency if you need it.
- WPEmerge\response() is now \App::response().
- WPEmerge\output() is now \App::output().
- WPEmerge\json() is now \App::json().
- WPEmerge\redirect() is now \App::redirect().
- WPEmerge\view() is now \App::view().
- WPEmerge\error() is now \App::error().
- WPEmerge\render() is now \App::render().
- WPEmerge\layout_content() is now \App::layoutContent().
- WPEmerge\run() is now \App::run().
The new App class makes it possible to have several WP Emerge instances workign side-by-side which was critical in order to support WP Emerge usage in plugins – check out the WP Emerge Starter Plugin below.

The new App class makes testing significantly easier as you can mock any and all aliases during testing:

// Since we don't want to test WP Emerge internals,
// we can overwrite them during testing:
\App::alias( 'view', function ( $view ) { return $view; } );

// or we can replace the entire app instance:
\App::setApplication( new MyMockApplication() );

The Blade and Twig extensions now use the new WP Emerge generic cache directory configuration option by default – see “What’s New” for more information.
\WPEmerge\Requests\RequestInterface now extends Psr\Http\Message\ServerRequestInterface.
\WPEmerge\Requests\Request is now PSR-7 compatible with Psr\Http\Message\ServerRequestInterface.
Several methods have been affected:
- Request::get() is now Request::query().
- Request::post() is now Request::body().
- Request::cookie() is now Request::cookies().
- Request::headers( $key, $default ) will now return an array of header values if $key is specified or an associative array of arrays of values otherwise.
  If you wish to get the value for a header as a single string use Request::getHeaderLine( $key ) instead.
\WPEmerge\Routing\RouteInterface::handle() has been replaced with a new getHandler() method. \WPEmerge\Routing\Route class has been updated to match.

'routes' configuration value structure has been altered slightly to allow you to override the default attributes.

// Before:
'routes' => [
  'web' => 'web.php',
  'admin' => 'admin.php',
  'ajax' => 'ajax.php',
],

// After:
'routes' => [
  'web' => [
    'definitions' => 'web.php',
    // Optional:
    'attributes' => [ ... ],
  ],
  'admin' => [
    'definitions' => 'admin.php',
    // Optional:
    'attributes' => [ ... ],
  ],
  'ajax' => [
    'definitions' => 'ajax.php',
    // Optional:
    'attributes' => [ ... ],
  ],
],

The App Layout comment annotation for PHP views has been changed to just Layout.
Removed Response::view() – use \App::view() instead.
Application::getContainer() is now \App::container().
NameProxyViewEngine::__construct() signature has changed.
ErrorHandle::__construct() signature has changed.
Various other internal classes have had their constructor signatures changed.
The 'whoops' key in the container has been changed to 'Whoops\Run' (\Whoops\Run::class).

What’s New

Framework

Added named routes.
You can now assign unique names to your routes and then refer to them to generate a route url:

// Adding a name to a route:
\App::route()
  ->get()
  ->url( '/dashboard/{user}' )
  ->name( 'user-dashboard' )
  ->handle( ... );

// Getting a route URL even with arguments:
App::routeUrl( 'user-dashboard', [ 'user' => 123 ] );

There is now a new 'cache' configuration key which allows you to override the default directory which extensions should use for caching purposes.
The default value is {Uploads Directory}/wpemerge/cache.
You can now get the current route instance from inside middleware or controllers using $request->getAttribute( 'route' ).
You can now get the current route arguments from inside middleware or controllers using $request->getAttribute( 'route_arguments' ).

You can now specify middleware at the controller level, with options to specify which methods that middleware should apply to:

use WPEmerge\Middleware\HasControllerMiddlewareInterface;
use WPEmerge\Middleware\HasControllerMiddlewareTrait;

class MyController implements HasControllerMiddlewareInterface {
  use HasControllerMiddlewareTrait;

  public function __construct() {
    $this->middleware( 'middleware1' );
    $this->middleware( 'middleware2' )->only( 'method1' );
    $this->middleware( 'middleware3' )->except( 'method2' );
  }
}

A new \Whoops\Handler\PrettyPageHandler::class key is available in the container which provides access to the Whoops error screen instance. Useful if you wish to blacklist environment values from appearing e.g.:
```
// Hide the MYSQL_PASSWORD from the error page:
$container[ \Whoops\Handler\PrettyPageHandler::class ]
->blacklist( '_ENV', 'MYSQL_PASSWORD' );
```
View composers are now applied to top-most templates loaded by WordPress even when a route is not active.
PHP mixin classes are now shipped with the framework which help IDEs detect built-in Application aliases.
You can now configure default route attributes for every group (web, admin, ajax) via configuration.
A WPEMERGE_VERSION constant has been added to provide easy programatical access to the currently loaded WP Emerge version.
Added a 'debug'->'enable' configuration option allowing you to override the debug status of WP Emerge. The value defaults to the value of WP_DEBUG.
Added a new 'view_composers' configuration option which gives control over view composer settings. Currently allows you to adjust the default namespace for view composer classes.
Action name can now be passed to the csrf middleware (e.g. ‘csrf:my_nonce_action_goes_here’).
Errors caught by the ErrorHandler class will now be logged to debug.log as well.
Added a new App::closure() helper which gives static access to container services. Allows taking advantage of the service container outside of WP Emerge (e.g. for REST API handling).
Query filters can now be applied to custom route conditions as long as they implement the new \WPEmerge\Routing\HasQueryFilterInterface interface.
Admin and AJAX error responses will not attempt to load error-admin.php and error-ajax.php, respectively, falling back to error.php if not available.
Simplified internals.
Improved overall performance.
Removed the autoloaded load.php and functions.php files.
Fixed duplicate headers in certain cases (htmlburger/wpemerge-theme#35).
Fixed extendConfig() merging indexed arrays incorrectly.
Fixed 'get_header', 'get_footer' and similar actions being called twice when using Blade views and WooCommerce.
Fixed Url::getPath() not always producing the expected result.
Fixed ErrorHandler not outputting displayed errors to debug.log when in debug mode.

Starter Plugin

Introduced the WP Emerge Starter Plugin.
Similarly to the starter theme, this project alows developers to create powerful plugins utilizing the WP Emerge framework.
Comes with all of the features the starter theme and more. Check out the documentation for more information.

yarn release will now remove all non-whitelisted options from the production config.json file. The whitelist is found in the release.configWhitelist key of config.json itself.
yarn build now also produces unminified bundles in order to support SCRIPT_DEBUG mode.
The release.include key in config.json now accepts globs.
config.json.dist has been updated with new required keys.
CSS media queries are now combined to further reduce CSS bundle size.
Replaced UglifyJS with Terser which produces smaller bundles.
Fixed config.json being parsed at runtime instead of being available as an object literal for improved performance.
A new wpemerge shortcut has been added to the theme and plugin to allow for easier CLI access:
```
php wpemerge list
```
