VanillaHtmlFormatter: how to customize, add attributes and class

R_J

Since I have no addon but a plugin, I assume I should either use "gdn_pluginManager_afterStart" or "container_init" and I have chosen "container_init". The file in /settings/bootstrap.php is not included

  // Bootstrapping.
   foreach ($addonManager->getEnabled() as $addon) {
       /* @var Addon $addon */
       if ($bootstrapPath = $addon->getSpecial('bootstrap')) {
           $bootstrapPath = $addon->path($bootstrapPath);
           include_once $bootstrapPath;
       }
   }

   // Plugins startup
   $addonManager->bindAllEvents($eventManager);

   if ($eventManager->hasHandler('gdn_pluginManager_afterStart')) {
       $eventManager->fire('gdn_pluginManager_afterStart', $dic->get(Gdn_PluginManager::class));
   }

   // Now that all of the events have been bound, fire an event that allows plugins to modify the container.
   $eventManager->fire('container_init', $dic);
});

With that code in my plugin (I've also tried RJPlugins\CKEditorHtmlFormat and \RJPlugins\CKEditorHtmlFormat)

   public function container_init(Container $dic) {
       $dic->rule(FormatService::class)->addCall(
           'registerFormat',
           [
               'Html',
               new \Garden\Container\Reference(CKEditorHtmlFormat::class)
           ]
       );
   }

I receive the following error, which makes absolutely no sense to me:

Fatal Error in Gdn_Session.start();
Call to a member function getSession() on null
The error occurred on or near: /usr/share/nginx/html/vanilla/installations/release_current/library/core/class.session.php

439: 

440:        // Now retrieve user information.

441:        if ($this->UserID > 0) {

442:            // Instantiate a UserModel to get session info

443:            $this->User = $userModel->getSession($this->UserID);

444: 

445:            $userSignedIn = false;

446:            if ($this->User) {

447:                $this->permissions->setPermissions($this->User->Permissions);

Backtrace:

[/usr/share/nginx/html/vanilla/installations/release_current/library/core/class.auth.php:64] Gdn_Session->start();

[/usr/share/nginx/html/vanilla/installations/release_current/index.php:22] PHP::require_once();

Looks like what I'm doing in container_init is totally wrong.

Okay, this is where I am:

1. In my plugin I have that method:

   public function container_init(Container $dic) {
       $dic->rule(Vanilla\Formatting\FormatService::class)->addCall(
           'registerFormat',
           [
               'Html',
               new \Garden\Container\Reference(RJPlugins\CKEditorHtmlFormat::class)
           ]
       );
   }

2. I have that CKEditorHtmlFormat:

<?php

namespace RJPlugins;

use Vanilla\Formatting\Formats\HtmlFormat;
use Vanilla\Formatting\Html\HtmlSanitizer;
use VanillaHtmlFormatter;
use Vanilla\EmbeddedContent\LegacyEmbedReplacer;
use Gdn;
use Vanilla\Formatting\Formats\StaticCacheTranslationTrait;
use Vanilla\Formatting\Htm;

/**
 * Handle special markup generated by CKEditor5.
 *
 * CKEditor5 inserts additional CSS classes which are stripped out by Vanillas
 * default Html renderer.
 *
 */
class CKEditorHtmlFormat extends HtmlFormat {

   // use StaticCacheTranslationTrait;

   const FORMAT_KEY = "html";

   /** @var HtmlSanitizer */
   private $htmlSanitizer;

   /** @var HtmlEnhancer */
   private $htmlEnhancer;

   /** @var bool */
   private $shouldCleanupLineBreaks;

   /** @var HtmlPlainTextConverter */
   private $plainTextConverter;

   /**
    * Constructor for dependency injection.
    *
    * @param HtmlSanitizer $htmlSanitizer
    * @param HtmlEnhancer $htmlEnhancer
    * @param HtmlPlainTextConverter $plainTextConverter
    * @param bool $shouldCleanupLineBreaks
    */
   public function __construct(
       HtmlSanitizer $htmlSanitizer,
       HtmlEnhancer $htmlEnhancer,
       HtmlPlainTextConverter $plainTextConverter,
       bool $shouldCleanupLineBreaks = true
   ) {
       $this->htmlSanitizer = $htmlSanitizer;
       $this->htmlEnhancer = $htmlEnhancer;
       $this->plainTextConverter = $plainTextConverter;
       $this->shouldCleanupLineBreaks = $shouldCleanupLineBreaks;
   }

   /**
    * @inheritdoc
    */
   public function renderHtml(string $content, bool $enhance = true): string {
return 'test';
...

I would expect that this simply returns a "test" for every Html post, but it does not, it simply renders them as html like before...
