Removing the Outline panel (#374 / #375) took away the only reader of the client-side command marks. The scanner kept running on every batch of PTY output, and it was the one scanner that forced the batch to be split before it reached the emulator, so it was not free. Gone: `MarkScanner`, `Marks`, `CommandMark`, `record_mark`, `Cut::Mark` and the tests that only covered them. With the cursor cut as the sole cut left, the offset sort is a no-op and goes too — `ParkedCursorScanner` already reports in ascending order — and `Cut` itself collapses into a plain `CursorCut`. Kept: `zle_tok` and `mode_tok` read the same OSC 133 bytes and are load-bearing for `zle_reading` / `shell_vi_mode`, including the deliberate live-vs-snapshot split. Daemon-side OSC 133 handling is untouched. Dropping `marks().clear()` left `clear_scrollback` with no anchored-state invalidation at all, and it never had any for the other store that needs it: kitty image placements are anchored to an absolute scrollback row, so purging the history moves every anchor and the frame paints over unrelated text or resolves past the viewport, with no redraw coming since the daemon does not replay out-of-band image frames. Clear the image store there, as the reattach path already does, and route the purge through `Term::clear_screen(ClearMode::Saved)` so a selection reaching into the discarded rows is invalidated instead of clamping onto the viewport. Closes #378
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
