* fix(host): save local files atomically via a temp file and rename LocalHost::write_file truncated the target in place, so a crash, a full disk or a killed process mid-save destroyed the user's file. It now writes a hidden sibling temp file, syncs it, keeps the old file's mode and renames it over the target, removing the temp file on any error. It still writes in place where a rename would change something visible: a non-regular target (symlink, directory, FIFO), a read-only file, and on Unix a hard-linked file or one owned by another user, or when the temp file cannot be created (e.g. a read-only directory). * feat(editor): add editor_text for encodings, line endings, indentation and EditorConfig A pure module the code editor will use when loading and saving files: decode detects BOMs, binary files, UTF-8, GB18030 and a lossless Windows-1252 fallback and normalises CRLF; encode restores the exact bytes and names the first unrepresentable character; detect_indent infers tabs or a 2/4/8 space width with language defaults; and editorconfig_for resolves .editorconfig sections with save-time rules. * feat(editor): share buffers across tabs, guard unsaved work, add a file strip - One buffer per file per window; tabs list which buffers they show. The same file open in two tabs is no longer two diverging copies. - Closing a tab, its last pane, the window, or quitting asks about unsaved files (Save / Cancel / Discard) instead of dropping them. Bulk closes skip tabs with unsaved files; a tab that vanishes any other way hands its unsaved buffers to the tab in front. - File tree rename/delete now retarget or flag the open buffer, so a save no longer recreates the old path. - Saves check the file's mtime first and ask before overwriting a change made elsewhere; this is the only detection SFTP buffers get. - Dirty is a comparison with the saved text, so undoing back clears it. - Reloads replace only the changed span as an ordinary edit, keeping undo. - Load/save go through editor_text: encoding, BOM and CRLF round-trip, indentation is detected, .editorconfig is honoured. - Header shows a strip of open files; New File, Save As (native panel locally, a path bar remotely), Go to Line (Ctrl+G), and the status bar shows indentation, encoding and a clickable line ending. - Open files are remembered per tab across restarts. * feat(search): quick open a file by name from a Files tab Search Everywhere gains a Files tab that finds any file in the active tab's project by fuzzy name and opens it in the built-in editor, with `name:line[:col]` jumping to that spot. The list comes from one walk of the project through the host (Host::search with an empty query), so it works the same on local, SSH and WSL workspaces and skips what the tree hides: dotfiles, .git and gitignored paths. The walk is capped at 50k entries / 20k directories, kept between openings and revalidated in the background each time the search opens. Files join the All tab once a query finds them. Go to File... is bound to Cmd+O on macOS (Cmd+P is already Search Everywhere) and ships unbound elsewhere, where every obvious chord is taken or owed to the shell. * chore(editor): allowlist the editor session file, tidy lints * fix(editor): keep restored file order, drop stale close waits, carry files through tab merges - Background arrivals (restore, merge, rescue) append to the strip in order instead of inserting beside the active file, which reversed them. - A cancelled Save As, a dismissed path bar, or a dropped buffer cancels any close that was waiting on that save. - Merging a tab into another carries its open files along. - A shell exiting closes its tab without a prompt it could not honour; unsaved buffers move to the tab in front. - Tabs rebuilt under the same id (server restart) restore their files. * fix(host): only fall back to an in-place write when the rename is refused On Windows every failure of the atomic save fell back to fs::write, including a failure while staging the temp file. A full disk would then truncate the original in place, the very loss the temp file prevents. Staging errors now return as-is; only a refused rename (a file held open elsewhere) takes the in-place path.
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
A background server owns your shells and panes — not the window. Everything below follows from that.
- 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
- Agent-aware — Claude Code, Codex & co.: status, notifications, and git context for every repo at once
- Scriptable by agents — one agent opens a pane for another, hands off a task, waits, and reads the result, with or without the GUI running
- Editor-grade input — suggestions, completion, highlighting, history search, with no plugin to install
- Remote development — files, repos, panes, and git data stay on the remote machine, over a native SSH stack

Supported agents
Detection is free: brand avatar, branch + diff, tab title.
Status takes one click under Settings → Integrations to install that agent's hook,
and brings the status dot, notifications, the tray icon, tty7 wait, and resume
after a reboot. Fork needs both — the agent's own fork command, and the hook
that tells tty7 which session to fork.

None of them are wrapped or proxied — the agent you start is the agent you get,
in a normal PTY, with its own interface. An agent launched through a wrapper
script can be mapped to one by name with agent_commands in config.json.
Every agent on your PATH is also a row in Search Everywhere (Agent: Claude Code, …)
that opens it in a new tab; agent_launch sets the command line it starts with.
