48-49: LGTM! The translations are correct and consistent.

The new German translations for the editor controls are accurate:

• "Farbe" is the correct translation for "color"
• "Emoji" is kept as is, which is correct as it's a commonly used loanword in German

src/main/webapp/app/shared/metis/posting-markdown-editor/posting-markdown-editor.component.ts (4)

15-15: LGTM: Import statements are well-organized.

The new imports are properly organized and necessary for implementing the emoji picker overlay functionality.

Line range hint 71-88: Verify keyboard accessibility for emoji picker.

Since we're adding UI interaction elements, ensure that the emoji picker is keyboard accessible (can be opened with keyboard, navigated with arrow keys, and closed with Escape).

Run the following to check for keyboard event handlers:

#!/bin/bash
# Search for keyboard event handling in EmojiAction
ast-grep --pattern 'keydown' 
ast-grep --pattern 'keyup'
ast-grep --pattern 'keypress'

---

88-88: Consider grouping related actions together.

While the EmojiAction implementation looks correct, consider grouping it with other text enhancement actions (like UserMentionAction) for better toolbar organization.

Let's verify if there are any existing action grouping patterns:

#!/bin/bash
# Search for other components that might have action grouping patterns
rg -A 5 'defaultActions.*=' 'src/main/webapp'

71-73: Verify cleanup of overlay subscriptions.

While the constructor parameters are properly organized, ensure that any subscriptions created by the Overlay service are properly cleaned up to prevent memory leaks.

Consider implementing OnDestroy and cleaning up subscriptions:

-export class PostingMarkdownEditorComponent implements OnInit, ControlValueAccessor, AfterContentChecked, AfterViewInit {
+export class PostingMarkdownEditorComponent implements OnInit, ControlValueAccessor, AfterContentChecked, AfterViewInit, OnDestroy {
+    private readonly destroy$ = new Subject<void>();
+
+    ngOnDestroy(): void {
+        this.destroy$.next();
+        this.destroy$.complete();
+    }

Let's verify if there are any overlay subscriptions that need cleanup:

src/main/webapp/app/shared/markdown-editor/monaco/markdown-editor-monaco.component.html (2)

Line range hint 1-231: LGTM! Well-structured template with modern Angular syntax.

The template demonstrates excellent organization with clear separation of concerns between edit, visual, and preview modes. The consistent use of the new Angular control flow syntax (@if and @for) aligns with best practices.

---

Line range hint 1-238: LGTM! Excellent compliance with Angular coding guidelines.

The template consistently uses the new Angular control flow syntax (@if and @for) throughout, fully adhering to the coding guidelines.

src/main/webapp/app/shared/markdown-editor/monaco/markdown-editor-monaco.component.ts (1)

48-48: LGTM! Import statement follows Angular guidelines.

The import statement for EmojiAction is properly organized and consistent with other action imports.

src/main/webapp/app/shared/monaco-editor/model/actions/emoji.action.ts (2)

61-67: Review the necessity of setting 'width' to '0' in overlay configuration.

The overlay configuration sets width: '0', which might not be required and could lead to display issues with the emoji picker. Verify if this setting is necessary or if it can be omitted.

79-81: ⚠️ Potential issue

Ensure subscriptions are properly cleaned up to prevent memory leaks.

While disposing of the overlayRef helps manage resources, it's important to verify that all subscriptions, such as the one from backdropClick().subscribe, are also properly cleaned up to prevent memory leaks.

Run the following script to check for potentially unmanaged subscriptions:

✅ Verification successful

Let me analyze the code further to verify the subscription cleanup concern.

Based on the code analysis, I can now provide a final response.

The subscription cleanup is properly handled

The subscription cleanup concern in emoji.action.ts is properly managed through multiple mechanisms:

1. The EmojiAction class extends TextEditorAction which implements Disposable interface and provides cleanup through its dispose() method
2. The overlayRef is properly cleaned up in the destroyEmojiPicker() method which is called:
   • When the emoji picker is closed via backdrop click
   • When a new emoji picker is opened
   • When an emoji is selected
3. The subscription to emojiSelect is automatically cleaned up when the overlayRef is disposed, as it's tied to the component lifecycle through the Angular CDK's overlay system
4. The subscription to backdropClick is also automatically cleaned up when the overlayRef is disposed

The implementation follows Angular CDK's overlay best practices where cleanup is handled through the disposal of the overlay reference, which internally manages all associated subscriptions.

11-11: Import statement is appropriate.

The import of Subject from 'rxjs' is necessary for handling observables in the test cases.
