Three defects in the document column, each with a guard test that fails without its fix. The tab strip did not know a column had taken width off it. On macOS the strip lives inside the terminal column and sizes itself to the window less the detail panel, so a docked document left it 340 points wider than the column it sits in and the chips ran on under the column — the same overrun the panel's own reservation was added for. Everywhere else the strip spans the workspace and the column's hoisted header is drawn over its trailing end with no fill of its own, so a chip left under it showed through the file name and stayed clickable through it. The column's width now comes off `strip_w` on macOS and off `corner_w` elsewhere, which is where the panel's already goes. The divider wrote widths the file would not keep. `Config::sanitize` holds `document_ratio` to 0.2..=0.8; the drag clamped in pixels only, so a column pushed against either edge of a wide window was saved outside that band and reopened somewhere else — on a 2560-point body, 232 points from where it was dropped. The band is a pair of shared constants now and the drag clamps to it, the way the font size and its stepper were made to agree in #550. The palette named the config's layout rather than the tab's. Fill is per tab, so a tab told to fill was still offered "Document: Fill Window" — a row that named the state it was already in and did the opposite. It reads the active tab through `ChromeState` now. Also: `document_layout`'s doc comment still described the global switch an earlier draft had, three lines after the field became a per-tab default.
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
