* feat(sidebar): tail-first label elision and a hover card for hidden details ff * fix(sidebar): keep the head of a non-path label, and let the card expand what the row hid The elision landed with four gaps between what a row hides and what the hover card can give back. A renamed tab is elided like anything else, but `sidebar_info` still carried the old tooltip's guard and bailed out on any non-empty `tab.name`, so a long custom name was shortened by the row and the card refused to spell it out. An empty terminal title took the opposite path: the row falls back to `Shell 3`, the card compared that placeholder against the empty string it came from, found them different, and opened on a row that had hidden nothing. Both came from deriving the same strings twice; the row now hands `sidebar_info` what it rendered next to what it rendered it from, and the card is decided by comparison alone. `elide_path_keep_tail` was applied to every title, but a title is not always a path — `npm run dev`, or a name someone typed. Dropping the head of those says less than the truncation this replaced, so `elide_label` picks the rule: tail-first for a path, both edges otherwise. `elide_keep_edges` promised both ends and delivered neither on a token with no break in reach: the head ran to the 12-glyph cap, `head…` alone overran the budget, and it fell through to a bare tail. It now tries shorter heads before giving up, and never trades the whole tail away for a longer head (`feature/…` became `fea…thing`). Also: measure the active row at the MEDIUM weight it actually renders at; subtract the list's own padding from the text budget, so a label that "just fits" is not handed back to CSS truncation; rejoin a path with the separator it arrived with, instead of spelling one tab `C:\Users\dev\app` while it fits and `C:/…/app` once it does not; count the gap between the two diff counts rather than the space standing in for it; let the card wrap instead of truncating the one string it promised in full; and read the remote host off the same leaf the title came from. The elision tests shape through gpui's `NoopTextSystem`, where every glyph is one em — deterministic across the three CI targets, but blind to the proportional and CJK widths this exists for. Said so where the fixtures are built, rather than implying the pixels are real. --------- Co-authored-by: l0ng-ai <ysdpk123@gmail.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
