callumalpass deccb5d962 Scope autocomplete CSS to TaskNotes modals only 
Prefix all CodeMirror autocomplete styles with .tasknotes-plugin
to prevent affecting other plugins or Obsidian's native editors.

This ensures our styling is isolated to TaskNotes UI components.

Technical Implementation

Files Created

  1. src/editor/EmbeddableMarkdownEditor.ts

    • Wrapper around Obsidian's internal ScrollableMarkdownEditor
    • Configurable options for callbacks and extensions
    • Based on Fevol's implementation

  2. src/editor/NLPCodeMirrorAutocomplete.ts

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

Files Modified

  1. src/modals/TaskCreationModal.ts

    • Replace textarea with markdown editor
    • Add getNLPInputValue() helper
    • Wire up autocomplete extension
    • Clean up editor on close

  2. src/modals/TaskEditModal.ts

    • Add markdown editor for details field
    • Override createDetailsSection()
    • Clean up editor lifecycle

  3. styles/task-modal.css

    • NLP editor styling (80-200px)
    • Details editor styling (200-400px)
    • CodeMirror autocomplete styling
    • 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
