* feat(tabs): drag a tab in as a pane, and a pane out as a tab A tab dragged by its chip or its sidebar row can be dropped over the panes to become one of them, and a pane dragged by its grip can be dropped on the strip or the sidebar to become a tab of its own. Both carry the panes across as they are: nothing is spawned and nothing is killed, so a shell mid-command, an SSH session or an agent mid-turn keeps running. The landing is read the way a pane drag's already is, minus the middle: an arriving tab has nothing here to trade places with, so a pane's core means "split it the way it is longest". A tab that was itself split arrives with its own shape intact and takes one share of the row or column it joined. A pane on its way out is offered a caret between two tabs, and the last pane in a tab is offered nothing, being a tab of its own already. Picking a tab up no longer switches to it: the strip and the sidebar now activate on the click rather than on the press. Without that the merge cannot be expressed at all — pressing the tab to drag it would put it on screen, leaving no other tab to drop it into. Two things in the machine tree had to follow: * Panes that change tabs are told as PaneMove, one at a time, rather than as a tab closing and another being rebuilt around them. * The tabs the machine already has are reconciled before new ones are created, so a pane leaving for a tab of its own is given up by the old tab before the new one asks to register it. The machine refuses a pane that is in two tabs at once, and the refusal desynced the window. Closes #621 * test(tree-sync): a tab grafted above a whole layout still converges * fix(tabs): keep a click on the close button from switching tabs Switching on the release rather than the press means every click inside a chip or a sidebar row now reaches the row itself, and gpui-component's `Button` does not stop propagation on a click it handled. So one click on a tab's close button ran `close_tab(i)` and then `activate(i)` — with `i` by then naming whichever tab had slid into that slot, which moved the active tab somewhere nobody asked for. A click into the rename field did the same: it switched away from the tab whose name was being typed, and took the focus out of the field with it. Both now hold the click where they handled it, the way they already held the press. --------- Co-authored-by: l0ng-ai <24760907+l0ng-ai@users.noreply.github.com>
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
