   • Handles @, #, +, and status triggers
   • Integrates with existing TaskNotes services

Files Modified

   • Focus states and hover effects

Dependencies Added

• @codemirror/autocomplete - Autocomplete system
• @codemirror/state - (already present)
• monkey-around - For editor prototype resolution

How It Works

NLP Input Flow

1. User types in markdown editor
2. Text triggers autocomplete on @, #, +, or status trigger
3. CodeMirror shows styled suggestions
4. User selects or types manually
5. Preview updates in real-time
6. Ctrl+Enter saves the task

Autocomplete Flow

1. User types trigger character (@, #, +, status)
2. NLPCodeMirrorAutocomplete detects trigger
3. Queries appropriate data source:
   • @ → cacheManager.getAllContexts()
   • # → cacheManager.getAllTags()
   • + → FileSuggestHelper.suggest()
   • status → StatusSuggestionService
4. Returns filtered, formatted suggestions
5. CodeMirror displays with custom CSS
6. Selection inserts text with spacing

Testing Checklist

• NLP editor appears in task creation modal
• Can type markdown with formatting
• Wikilinks work with [[
• Ctrl+Enter saves task
• @ shows context suggestions
• # shows tag suggestions
• + shows project suggestions
• Status trigger shows status suggestions
• Autocomplete is styled nicely
• Preview updates in real-time
• Modal closes without errors
• Editor properly cleaned up
• Details field in edit modal works
• Fallback textarea works if needed

Comparison: Before vs After

Before (Old Textarea)

• Plain text input
• AbstractInputSuggest for autocomplete
• Simple but limited
• No markdown features

After (Markdown Editor)

• Rich CodeMirror editor
• Full markdown support
• Wikilinks work natively
• CodeMirror autocomplete
• Better UX

Known Limitations

1. Internal API Usage

   • Uses Obsidian's internal ScrollableMarkdownEditor
   • May break in future Obsidian versions
   • Requires @ts-ignore in places

2. Plugin Extensions

   • Other plugins' CodeMirror extensions won't load automatically
   • Would need manual inclusion

3. No Toggle

   • Always uses markdown editor (no fallback setting)
   • Could add user preference in future

Performance Notes

• Autocomplete triggers on every keystroke (optimized with early returns)
• Uses same caching as old system
• FileSuggestHelper already optimized
• No noticeable performance impact in testing

Future Enhancements

Possible Improvements

1. Add settings toggle - let users choose old vs new editor
2. Shift+Tab shortcut - fill form from NLP (currently just Ctrl+Enter)
3. Custom autocomplete icons - different icons for contexts, tags, projects
4. Autocomplete ranking - score suggestions by relevance
5. Recent items first - show recently used contexts/tags first
6. Fuzzy matching - improve search algorithm
7. Rich preview cards - show project metadata in autocomplete

Low Priority

• Read/write mode toggle in editor
• Resizable editor height
• Custom syntax highlighting themes
• Integration with other plugin extensions
