Ctrl+\ sends ASCII 28 (File Separator) in legacy terminals. This is
commonly used as SIGQUIT in Unix.
Ctrl+] sends ASCII 29 (Group Separator) in legacy terminals. This is
commonly used as the telnet escape character.
Ctrl+_ sends ASCII 31 (Unit Separator) in legacy terminals. On US
keyboards, - and _ are on the same physical key, so this also functions
as an alias for Ctrl+-.
In legacy terminal mode (non-Kitty protocol), Alt+key is sent as ESC
followed by the key character. This was only supported for specific keys
(space, backspace, arrows) but not for regular letters.
Add support for Alt+letter sequences to enable keybindings like Alt+Y.
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
The 100ms timeout was causing Kitty protocol detection to fail when the
terminal response was delayed (e.g., due to event loop blocking during
startup). This resulted in shift+enter not working in some scenarios.
Changes:
- Remove timeout-based Kitty detection, process input immediately
- Detect Kitty response in stdinBuffer output (handles split data)
- Add modifyOtherKeys fallback for terminals without Kitty support
(matches xterm format \x1b[27;modifier;keycode~)
Pasted content containing Kitty key release patterns (e.g., :3F in bluetooth
MAC addresses) was incorrectly detected as a key release event and dropped.
The fix checks for bracketed paste markers before running pattern checks.
Also applied to isKeyRepeat() for consistency.
Closes#623
- Enable flag 2 in Kitty protocol for event type reporting
- Add isKeyRelease() and isKeyRepeat() functions
- Parse event type suffix (:1/:2/:3) in Kitty sequences
- Export KeyEventType type
- Added SymbolKey type with 32 symbol keys
- Added symbol key constants to Key helper (Key.backtick, Key.comma, Key.period, etc.)
- Updated matchesKey() and parseKey() to handle symbol key input
- Added documentation in coding-agent README with examples
- Add KeyId union type covering all valid key combinations
- Add Key helper object for autocomplete (Key.ctrl('c'), Key.escape, etc.)
- Update matchesKey signature to use KeyId instead of string
- Catches typos like 'esacpe' at compile time
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.
- Add new API type 'google-cloud-code-assist' for Gemini CLI / Antigravity auth
- Extract shared Google utilities to google-shared.ts
- Implement streaming provider for Cloud Code Assist endpoint
- Add 7 models: gemini-3-pro-high/low, gemini-3-flash, claude-sonnet/opus, gpt-oss
Models use OAuth authentication and have sh cost (uses Google account quota).
OAuth flow will be implemented in coding-agent in a follow-up.
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.
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 isCtrlD helper to keys.ts
- CustomEditor intercepts Ctrl+D and only triggers callback when editor is empty
- Single Ctrl+D with empty input exits immediately
- Update CHANGELOG to frame as feature (Kitty protocol support) not fix
- 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
