* fix(coding-agent): tree selector focuses nearest visible ancestor
When the selected entry is not visible (filtered out by mode change or a
metadata entry like model_change), walk up the parent chain to find the
nearest visible ancestor instead of jumping to the last item.
Fixes selection behavior for:
- Initial selection when currentLeafId is a metadata entry
- Filter switching, e.g. Ctrl+U for user-only mode
* fix(coding-agent): tree selector preserves selection through empty filters
When switching to a filter with no results, e.g. labeled-only with no
labels and back, the cursor would reset to the first message instead of
the original selection.
Track lastSelectedId as a class member and only update it when
filteredNodes is non-empty, preserving the selection across empty filter
results.
* test(coding-agent): add tree selector filter and selection tests
- Test metadata entry handling (model_change, thinking_level_change)
- Test filter switching with parent traversal (default ↔ user-only)
- Test empty filter preservation (labeled-only with no labels)
When moving up/down through lines of varying lengths, the editor now
remembers the original column position and restores it when reaching a
line long enough to accommodate it.
Example: cursor at column 10, move up to a shorter line (cursor clamps
to end), move up again to a longer line - cursor returns to column 10.
Implementation:
- Add preferredVisualCol instance property (nullable)
- Set it when moving to a shorter line during vertical navigation
- Clear it when arriving at a line that fits the preferred column
- Clear it on any horizontal movement or editing via setCursorCol()
- Detect line rewrap by checking if cursor is in middle of line
- When pressing right at end of prompt, set preferredVisualCol so
subsequent up/down navigation uses that column position
Add Bash/Readline-style character search:
- Ctrl+] enters forward jump mode, awaits next character, jumps to it
- Ctrl+Alt+] does the same but searches backward
- Multi-line search
- Case-sensitive matching
- Pressing the hotkey again cancels; control chars cancel and fall
through
* fix(tui): keep file suggestions open when typing in Tab-triggered mode
Previously, pressing Tab on an empty prompt or after a space would show
file suggestions, but typing a letter would dismiss them because the
text didn't look like a path pattern. Now the editor tracks whether
autocomplete was triggered via Tab (force mode) or naturally (regular
mode), and uses the appropriate suggestion method when updating.
* fix(tui): hide autocomplete when backspacing slash command to empty
Previously, typing / showed slash command suggestions, but pressing
Backspace to delete it showed file suggestions instead of hiding all
suggestions.
Instead of buffering `\` and waiting for the next key, let it be
inserted immediately. On Enter, check if preceded by `\` and treat as
newline.
Removed backslash handling from the Input component entirely.
When Tab triggers file autocomplete and there's exactly one matching
suggestion, apply it immediately without showing the menu. This makes
path completion faster by eliminating the extra Tab press to confirm.
This issue occurs when extension uses setEditorComponent. The
restoreEditor() callback was capturing this.editor AFTER
resetExtensionUI() (which restores defaultEditor), then adding that
captured editor back to the container - ignoring any new editor created
by extensions during session_start.
On success, use this.editor (may be custom editor from extension).
On failure, restore the fallback editor (safe defaultEditor state).
Rename restoreEditor to dismissLoader to reflect its actual purpose.
Extension shortcuts registered via registerShortcut() were not firing
when the extension also used setEditorComponent(). This happened because
setEditorComponent() copied onExtensionShortcut from defaultEditor at
creation time, capturing undefined if setupExtensionShortcuts() hadn't
run yet.
The fix is to delegate to defaultEditor.onExtensionShortcut at call
time.
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.
setCustomEditorComponent() was not copying the paddingX setting from
the default editor to extension-provided editors. Also propagate live
changes from the settings callback.
- Add Ctrl+L (Open model selector) to /hotkeys command
- Add Alt+Enter (Queue follow-up message) to keyboard shortcuts table
- Add PageUp/PageDown (Scroll by page) to all documentation sections
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+-.
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
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.
