Add insertTextAtCursorInternal() to properly handle newlines by splitting
lines at the cursor position.
- Normalize line endings (CRLF/CR to LF)
- Handle single-line and multi-line insertion
- Position cursor at end of inserted text
- Call onChange only once at the end
Refactor handlePaste() to use insertTextAtCursorInternal() for
multi-line pastes, while retaining character-by-character insertion for
single-line pastes to preserve autocomplete triggering.
Undo snapshots are captured for all edit operations:
- Word insertion, backspace, forward delete
- Word/line deletion (Ctrl+W, Ctrl+U, Ctrl+K, Alt+D)
- Yank/yank-pop, paste, autocomplete completion
- Cursor movement starts a new undo unit
- setText() pushes snapshot when content changes
Additionally, history browsing captures the undo state on first entry.
Adds deleteWordForward action bound to Alt+D, which deletes from cursor
to the end of the current word and saves to kill ring for later yanking.
Consecutive forward kills append to the same kill ring entry.
Add kill ring functionality with:
- Ctrl+W/U/K save deleted text to kill ring
- Ctrl+Y yanks (pastes) most recent deletion
- Alt+Y cycles through kill ring (after Ctrl+Y)
- Consecutive deletions accumulate into single entry
- Add Focusable interface for components that need hardware cursor positioning
- Add CURSOR_MARKER (APC escape sequence) for marking cursor position in render output
- Editor and Input components implement Focusable and emit marker when focused
- TUI extracts cursor position from rendered output and positions hardware cursor
- Track hardwareCursorRow separately from cursorRow for differential rendering
- visibleWidth() and extractAnsiCode() now handle APC sequences
- Update overlay-test.ts example to demonstrate Focusable usage
- Add documentation for Focusable interface in docs/tui.md
Closes#719, closes#525
The Editor component now accepts TUI as the first constructor parameter,
enabling it to query terminal dimensions. When content exceeds available
height, the editor scrolls vertically keeping the cursor visible.
Features:
- Max editor height is 30% of terminal rows (minimum 5 lines)
- Page Up/Down keys scroll by page size
- Scroll indicators show lines above/below: ─── ↑ 5 more ───
Breaking change: Editor constructor signature changed from
new Editor(theme)
to
new Editor(tui, theme)
fixes#732
* fix(tui): expand paste markers when opening external editor
Add getExpandedText() method to Editor that substitutes paste markers
with actual content. Use it in Ctrl-G external editor flow so users
see full pasted content instead of [paste #N ...] placeholders.
* docs: add changelog entries for #444
Kitty and other smart terminals send a specific CSI u control code for
these shifted special keys, which are interpreted as a no-op by the
editor component. These should send the underlying key instead, matching
the behaviour of other TUI programs (e.g. readline, vim insert mode).
On less smart terminals, these key combinations are the same as the
non-shifted versions, and so already work with the existing code.
Previously, the Editor component used character-level (grapheme-level)
wrapping, which broke words mid-character at line boundaries. This
created an ugly visual experience when typing or pasting long text.
Now the Editor uses word-aware wrapping:
- Wraps at word boundaries when possible
- Falls back to character-level wrapping for tokens wider than the
available width (e.g., long URLs)
- Strips leading whitespace at line starts
- Preserves multiple spaces within lines
Added wordWrapLine() helper function that tokenizes text into words
and whitespace runs, then builds chunks that fit within the specified
width while respecting word boundaries.
Also updated buildVisualLineMap() to use the same word wrapping logic
for consistent cursor navigation.
Added tests for:
- Word boundary wrapping
- Leading whitespace stripping
- Long token (URL) character-level fallback
- Multiple space preservation
- Edge cases (empty string, exact fit)
- Skip trailing whitespace before deleting word (readline behavior)
- Make word navigation grapheme-aware using Intl.Segmenter
- Add Ctrl+Left/Right and Alt+Left/Right word navigation to Input
- Accept full Unicode input while rejecting control characters (C0/C1/DEL)
- Extract shared utilities to utils.ts (getSegmenter, isWhitespaceChar, isPunctuationChar)
- Fix unsafe cast in Editor.forceFileAutocomplete with runtime type check
- Add comprehensive tests for word deletion and navigation
- Fix //tmp issue: distinguish slash commands from file paths by checking if anything precedes the /
- Fix symlinks to directories (like /tmp) not getting trailing slash
Extended the Kitty protocol parser to handle functional keys with
~ terminator (Delete, Insert, PageUp, PageDown) and Home/End keys.
Updated editor.ts and input.ts to use the new helpers.
Backspace, Delete, and arrow keys now use Intl.Segmenter to operate
on grapheme clusters instead of individual UTF-16 code units. This
fixes deletion of emojis and other multi-codepoint characters.
fixes#240
Fixes keyboard input in Ghostty on Linux when Num Lock is enabled.
The Kitty protocol includes Caps Lock (64) and Num Lock (128) bits
in modifier values. Now masks out lock bits when matching shortcuts.
Added helper functions: isArrowUp/Down/Left/Right, isEnter, isTab,
isBackspace, isShiftEnter, isAltEnter, isAltLeft/Right, isCtrlLeft/Right
fixes#243
Add isEscape() helper that handles both raw (\x1b) and Kitty protocol
(\x1b[27u) Escape sequences. Update all components that check for
Escape key to use the new helper.
- Add isCtrlA/C/E/K/O/P/T/U/W helper functions that check both raw and Kitty formats
- Add isAltBackspace helper function
- Refactor editor.ts, input.ts, select-list.ts to use helper functions
- Refactor custom-editor.ts, session-selector.ts, user-message-selector.ts
- Add CHANGELOG entry for the Shift+Enter fix
Enable the Kitty keyboard protocol on terminal start to receive enhanced
key sequences that include modifier information. This fixes Shift+Enter
not working in Ghostty, Kitty, WezTerm, and other modern terminals.
Changes:
- Enable Kitty protocol on start (\x1b[>1u), disable on stop (\x1b[<u)
- Add centralized key definitions in packages/tui/src/keys.ts
- Support both legacy and Kitty sequences for all modifier+key combos:
- Shift+Enter, Alt+Enter for newlines
- Shift+Tab for thinking level cycling
- Ctrl+C, Ctrl+A, Ctrl+E, Ctrl+K, Ctrl+U, Ctrl+W, Ctrl+O, Ctrl+P, Ctrl+T
- Alt+Backspace for word deletion
- Export Keys constants and helper functions from @mariozechner/pi-tui
Editor text wrapping now uses grapheme-aware width calculation instead
of string length. Fixes crash when pasting text containing emojis like
✅ or CJK characters that are 2 terminal columns wide.
Browse previously submitted prompts using Up/Down arrow keys, similar to
shell history and Claude Code's prompt history feature.
- Up arrow when editor is empty: browse to older prompts
- Down arrow when browsing: return to newer prompts or clear editor
- Cursor movement within multi-line history entries supported
- History is session-scoped, stores up to 100 entries
- Consecutive duplicates are not added to history
Includes 15 new tests for history navigation behavior.
- Up/down arrows now navigate visual (wrapped) lines instead of logical lines
- Fixed double cursor display at wrap boundaries
- Added word by word navigation via Option+Left/Right or Ctrl+Left/Right
- Updated README keyboard shortcuts documentation
Closes#61
When pressing Enter on a highlighted slash command suggestion (e.g., typing
`/mod` with `/model` highlighted), the completion is now applied before
submitting. Previously, the partial text was submitted instead of the
selected command.
Fixes#49
- Fixed catastrophic regex backtracking in extractPathPrefix that caused
terminal to hang when text contained many / characters (e.g., URLs).
Replaced complex regex with simple lastIndexOf approach. (#18)
- Fixed arrow keys moving both autocomplete selection and editor cursor
by adding missing return statement after handling arrow keys in
autocomplete mode.
Closes#18
The horizontal borders around the input editor now change color based on
the current thinking level, providing immediate visual feedback:
- off: gray (default)
- minimal: dim blue
- low: blue
- medium: cyan
- high: magenta
The more thinking, the brighter/more vibrant the color.
Changes:
- Add public borderColor property to Editor component (packages/tui)
- Use borderColor instead of hardcoded chalk.gray for borders
- Add getThinkingBorderColor() helper in TuiRenderer
- Add updateEditorBorderColor() to apply color changes
- Update border color when:
- Cycling with Tab key
- Selecting via /thinking command
- Restoring session with thinking level set
- Use 'charCodeAt(0) >= 32' instead of open 'else' in handleInput()
- Use same filter in handlePaste() for consistency
- Prevents control characters while allowing all unicode
- More explicit and safer than accepting everything
- Add Ctrl+W for word deletion (stops at whitespace/punctuation)
- Add Ctrl+U for delete to start of line (merges with previous line at col 0)
- Change Ctrl+K from delete entire line to delete to end of line (merges with next line at EOL)
- Add Option+Backspace support in Ghostty (maps to Ctrl+W via ESC+DEL sequence)
- Cmd+Backspace in Ghostty works as Ctrl+U (terminal sends same control code)
- Update README and CHANGELOG with new keyboard shortcuts
Fixes#2, Fixes#3
