Teach the control dialect the semantic operations the machine tree serves: MachineGet / WorkspaceTree pulls, WorkspaceCreate / Rename / Remove / Touch / SetActiveTab, TabCreate / Close / Rename / Move / SetGroup, and PaneSplit / Close / SetRatio / Move / Replace. Replies carry the daemon's own tree types (a created workspace or tab comes back whole; close operations answer the pane ids that left the tree so the caller can kill their PTYs), and every operation broadcasts a ControlEvent::Layout delta to every connection but the writer's — the same origin-exclusion mechanism the record store uses, one delta at a time instead of whole-record last-writer-wins. The server advertises a new 'machine-tree' capability bit only when it actually carries a MachineStore; both daemons now do, alongside the retired opaque record store, which keeps serving unchanged while clients migrate. Delta fan-out rides its own bounded queue and forwarder thread per connection, so a peer that stopped reading stalls nobody's edit; the drop-on-overflow tradeoff is documented against the keepalive that reaps such a peer and the full pull every reconnect starts with. The request/reply/event enums lose their Eq derive: split ratios are f32. End-to-end tests drive the shipped tty7-server binary over real pipes: capability advertisement, tree ops landing in the server's own file, dead-pane revival across a real process restart, and delta delivery between two live clients.
tty7
A terminal workbench: shells, sessions, SSH, coding agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Sessions persist — quit or reboot; your shells keep running, no tmux
- Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
- Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume
