feat(web): find text in the terminal with Cmd/Ctrl+F - #11927
PwntasticKev wants to merge 7 commits into
Conversation
Adds a find bar to web and desktop terminals. With a terminal focused, mod+f (Cmd+F on macOS, Ctrl+F on Windows and Linux) or Ctrl+Shift+F opens it; it searches the full scrollback, including matches that span soft wraps, highlights every visible match on the canvas, and Enter/Shift+Enter move between matches and scroll them into view. Case-sensitive and regex modes are available, and Escape closes the bar and refocuses the terminal. Previously the shortcut fell through to the shell and typed a literal "f". The command is terminal.find and can be rebound in Settings > Keybindings.

🟠 High ghostty/search.ts:92
Regex searches can freeze the UI thread: a pattern such as (a+)+$ backtracks catastrophically when line 92 runs it synchronously against a long terminal line ending in a non-a character. Since terminal output is user-controlled, reject or complexity-limit unsafe patterns, or run matching off the UI thread with a timeout.

Fixed in 3026d25: regex search is removed. The query is always escaped and matched as a literal (new RegExp(escaped, "g" | "gi")), so a pathological pattern can no longer backtrack or block the terminal UI.

Terminal find now uses the shared pieces the app already has instead of parallel copies: - Soft-wrapped rows are joined with collectWrappedTerminalLinkLine from terminal-links, the same helper terminal link detection uses. - The regex and match-case toggles use SearchOptionButton, extracted from the project content search dialog so both surfaces share one control.
- Find is literal text only. Regex search is removed, so a pathological pattern can no longer block the terminal UI while scanning scrollback. - The find bar is a single compact pill (grip, input, match case, count, previous/next/close) using the same floating toolbar styling as the preview mini player. - Drag the grip to move the bar between the top-right and bottom-right of the terminal. It snaps to the nearer corner with the panel easing, a click or Enter on the grip flips it, reduced motion disables the animation, and the corner is remembered. - Escape and the find shortcut now work from anywhere in the bar, not only while the input has focus.
Find now lives in the terminal's floating button row instead of a separate draggable bar, so it takes no extra space: - A search icon sits at the left of the split/new/close buttons. Clicking it, or pressing the find shortcut, expands find leftward inside the same bordered group: input, match case, count, previous, next, close. Every segment uses the row's own button size and dividers, so the row stays 23px tall. Closing collapses it back to the icon. - With split panes or the terminal sidebar, where that row isn't shown, the find shortcut opens the same compact strip at the focused pane's top-right. - Drag and corner snapping are removed. - TerminalActionButton moves into its own module so find reuses the same tooltip button as the rest of the row.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Add native disabled-state support.
pointer-events-none in TerminalSearchBar blocks only pointer input. A keyboard user can still focus and activate navigation when matchCount is zero. Assistive technology also reports the buttons as enabled.
Add a disabled prop. Forward it to the native button. Set it on both navigation buttons.

- The match count and its divider only render once there is a query, so an empty find row no longer leaves a blank gap between Aa and the previous/next buttons. - Aa keeps its compact 11px size at the sm breakpoint instead of picking up the toggle's default text size. - The floating terminal button group sits in a flex wrapper, so it no longer rides a text baseline that moved it 2px when find opened or closed.
The match count now sits inside the find input as a small muted italic label instead of its own segment. The input keeps a fixed width with room reserved for the count, so typing or getting results never resizes the row.

What Changed
A small quality-of-life feature: find in the terminal.
With a terminal focused,
mod+f(Cmd+F on macOS, Ctrl+F on Windows and Linux) orCtrl+Shift+Fopens find. You can also click the new search icon at the left of the terminal's floating split / new / close buttons. Find expands leftward inside that same bordered button group, at the same 23px height, so it takes no extra space.n/totalcount sits inside the input, which keeps a fixed width.How it works:
GhosttyTerminalCore.searchRows()reads plain text for every screen row, plus soft-wrap flags, using libghostty-vt's formatter and grid refs. It does not change the selection or viewport.terminal/ghostty/search.tsescapes the query and matches it literally, which is linear-time. It maps matches to highlight columns (including wide characters) and handles navigation. It joins soft-wrapped rows with the existingcollectWrappedTerminalLinkLinehelper that terminal link detection already uses.GhosttyTerminalSurfaceowns search state and passes visible highlights to the Canvas renderer; highlight work runs only while a search has matches.max-widthtransition using the app's panel easing, skipped with reduced motion, and the collapsed controls areinert.TerminalActionButton, moved into its own module, is the same tooltip button the row already uses.SearchOptionButton, moved out of the project content search dialog, is the Aa toggle; it now accepts an optionalclassNamefor the row size.terminal.find, active only when a terminal has focus. Existingkeybindings.jsonfiles get the new defaults on startup; I checked this against a config created bymain.docs/user/terminal.md.Why
Terminal output in T3 Code is often long: agent logs, test runs, API responses. Before this change there was no way to search it. Pressing Cmd+F in the terminal typed a literal
finto the shell, and the browser's find can't see a canvas terminal. There's no existing shortcut for this either:mod+shift+fis project file search, and it only fires when the terminal is not focused. Jumping straight to anERRORline or a request ID is small, but it saves time every day.Surfaces:
