The find box keeps the last query on purpose — reopening on the word you just looked for is most of what a find bar is for. But the caret was wrong for it in both directions, so the kept query behaved like a prefix or a suffix instead of like a value you are about to replace. Reopened after closing, `default_value` left the caret at offset 0: ⌘F then "beta" over a kept "alpha" gave "betaalpha", 0/0, and no clue why. Re-focused while still open, the caret was at the end and typing appended instead — "alphaZZ". Every other find bar on the platform selects the text, and the earlier rename-box fix reached the same wall and settled for caret-at-end because `InputState::select_all` is `pub(super)` in the UI crate. It is reachable after all, just not as a method: the input binds ⌘A to a public `SelectAll` action, and a `FocusHandle` can be handed an action directly. Aiming it at the box's own handle rather than at whatever happens to be focused keeps it from selecting something else if focus moved. It goes through `on_next_frame` because actions route along the last drawn frame's dispatch tree, and a box created this turn is not in it yet. Verified in a dev window across all three paths: closed and reopened, re-focused while open, and empty (no selection to make, so nothing happens). The frame requirement is also why there is no unit test — the test harness never paints, so the callback never fires there.
tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
- Editor-grade input — suggestions, completion, highlighting, history search
- Remote development — files, repos, panes, and git data stay on the remote machine
- Native SSH — profiles, SFTP, port forwarding, and jump hosts
- Agent-aware — Claude Code, Codex & co.: status, notifications, git context
- CLI + Skills — agents create panes, run commands, and inspect output
