if cfg!(target_os = "linux") { window.zoom_window() }
else { window.titlebar_double_click() }
reads like a stylistic split and is a bug fix. gpui implements
`titlebar_double_click` on macOS only — everywhere else the trait method
is an empty default, so on Linux this row swallowed the double-click and
nothing zoomed. `zoom_window` is the maximise toggle there, and what
gpui-component's own `TitleBar` calls for the same reason. Windows needs
neither: the row maps to HTCAPTION and the OS has already acted.
Nothing in the code said any of that, so the obvious tidy — collapse the
branch to the one gpui documents — silently breaks Linux again. The
branch is byte-for-byte what it was when that was written.
Also `WindowMoveArm`, whose point is *where* the flag lives rather than
what it holds, and `last_focused`, which is why switching tabs returns
to the pane you left instead of the first one.
Checked `last_focused`'s reference to `remember_active_pane` before
restoring it, on the assumption it had rotted — it has not, the function
is still there and still called from two places, and `focus_target`
still falls back to `first_leaf()` exactly as described. My first grep
said otherwise because I had truncated it.
Measured function length across the tree while here: the only
production function over 400 lines is `Tty7App::render` at 578, which is
a gpui element tree — long, linear, and not something to split while
its behaviour cannot be verified visually.
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
