#268 ("strip every comment from the Rust sources") removed 38,164 comment lines. Much has been rewritten since, but 7,587 blocks still sit in front of code that is unchanged and now undocumented. Last commit I started implementing a pair of deliberate no-op stubs before `git log -L` turned up the stripped comment saying they were deliberate — which is the failure mode this class of loss produces. Seven restored here, chosen for documenting why something must not change rather than what it does: - `LinkShutdown` — "not optional politeness; without it a client cannot be closed". A reader parked in a blocking read is not woken by any flag, so closing has to act on the fd, and no std trait spans the transports. Nothing else says this. - `peek_frame_kind` / `is_error_kind` — why Attach is classified before the payload is paid for. - `FontFeatures` — a frozen config key deliberately replicating gpui's type so tty7-core parses without linking gpui. - `desired_tabs` / `every_leaf_is_native_ssh` — held vs permanently-invisible tabs, and why conflating them either deletes a daemon tab mid-revival or freezes a window's ordering forever. - `control_for` / `TreeLink` / `classify_tree_link` — local and remote links unified, and unserved as a fact about the peer rather than a transient down. Restored against the current code, not verbatim: three claims had gone stale and are corrected. `Duplex` has since adopted `LinkShutdown` (`Halves` carries one) rather than needing to; `peek_frame_kind` has two callers now, not one; and `gpui_font_features` moved out of `ui::app`.
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
