A pane learned its working directory from OSC 7 alone, which only shells tty7 manages to inject its integration into ever emit. A shell that execs into another one from its rc file (`exec fish` at the end of .zshrc), a nested shell started by hand, or any shell with no integration at all emits none — and since a pane's cwd is seeded with its spawn directory, such a pane does not report *no* directory, it reports a permanently stale one. New tabs and splits, the git probe and path completion all follow it to the wrong place, with nothing on screen to say why. Read the cwd from the process table too, on the same half-second foreground poll that already detects SSH sessions and coding agents, and reconcile it with what the pane reports: - A remote pane is left alone. The local process table can only see the ssh client's own directory, which is the confusion apply_remote_context clears the cwd to avoid in the first place. - No reading is "nothing to read", never "no cwd", so it cannot clear one. - When both name the same directory the shell's spelling wins. $PWD keeps the symlinked route the user walked in through, and that is the path a new tab should open in; only a genuine disagreement moves the pane. The three platform cwd readers move from DaemonPane methods to free functions so the reader thread can call them; the method stays as a thin delegate for List. Fixes #187
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
