Clients stopped sending WorkspaceList/Get/Put/Delete when the tree migration landed, so the coexistence scaffolding comes out: - core::workspace_store is deleted. Attachment and the data-directory resolution (TTY7_DATA_DIR, XDG fallback chain) move into core::machine, which was already their only consumer; Attachment loses its vestigial serde derives (it never crosses disk or wire). - The control dialect drops the four record verbs, the ReplyOk::Json payload they answered with, and the WorkspaceChanged event. Their serde names (and the workspace-store capability bit) are recorded as burned rather than reserved by any mechanism — the dialect has no numbered slots to hold, so a comment at each site is the guard, plus the handshake test asserting the bit never reappears. - host::server loses Services.workspaces, the verb arms, the per-connection store subscription and its WorkspaceChanged forwarder, and the store half of attach/detach/teardown. Attachment data now lives solely in the tree: a workspace the tree does not list records no data half (the registry's live handles still move, so takeover behaviour is unchanged), and it appears the moment the workspace does. Services::with_workspaces/and_machine collapse into with_machine; control_services becomes a single match. - The attach/takeover tests move onto MachineStore wholesale, attaching to workspaces created in a real tree; the record-store round-trip and fan-out tests go (tests/machine_tree.rs has carried the tree equivalents since the verbs landed), and tests/workspace_store.rs is deleted with the serde_json dev-dependency that existed only for it. machine.rs gains the two guarantees the old suite held uniquely: an attachment dies with its workspace structurally, and the default path resolution ends at the documented file. - The GUI's dead WorkspaceChanged arm and every stale doc reference go.
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
