Vim Mode Support

• New command: vim - Toggle between vim and emacs editing modes

️ Enhanced Text Editing

• Vim mode implementation with full modal editing support:

Normal Mode Commands:

• Movement: h (left), l (right), j (down), k (up)
• Line navigation: 0 (start of line), $ (end of line)
• Word navigation: w (next word), e (end of word), b (previous word)
• Document navigation: gg (first line), G (last line)

Editing Commands:

• i - Insert mode at cursor
• I - Insert mode at beginning of line
• a - Insert mode after cursor
• A - Insert mode at end of line
• x - Delete character under cursor
• d + motion - Delete with motion (e.g., dd for delete line, d$ for delete to end of line)
• D - Delete to end of line
• c + motion - Change (delete and enter insert mode)
• C - Change to end of line
• . - Repeat last change

Input Handling Refactoring

• Improved paste handling with better chunking for large text inputs
• Enhanced placeholder rendering with cursor display
• Better separation of concerns between input state management and rendering

Import Optimizations

• Streamlined Node.js imports:
• Combined imports from node:process (env, cwd)
• Combined imports from node:stream (PassThrough)
• Reduced redundant import statements

New Classes/Functions

• q6 class (renamed from Gd) - Enhanced text cursor with new methods:
• endOfWord() - Navigate to end of current/next word
• startOfFirstLine() - Navigate to document start
• startOfLastLine() - Navigate to last line start

• Uf2() - Core vim mode state machine handling modal editing
• jN1() - Vim-enabled text input component
• sx() - Refactored input rendering component
• y90() - Paste handling wrapper function

Settings

• New editorMode setting added to persistent configuration
• Default mode is "emacs" for backward compatibility

Switching to vim mode:

$ claude
> vim
Editor mode set to vim. Use Escape key to toggle between INSERT and NORMAL modes.

Using vim navigation:

# In NORMAL mode:
- Press 'i' to enter INSERT mode and start typing
- Press 'Escape' to return to NORMAL mode
- Use 'hjkl' for navigation
- Use 'dd' to delete a line
- Use '.' to repeat the last edit

Switching back to emacs mode:

> vim
Editor mode set to emacs. Using standard emacs-style keybindings.

The vim mode implementation provides a familiar editing experience for vim users while maintaining full compatibility with the existing emacs-style keybindings. The mode preference persists across sessions, so users only need to switch once.
