Nothing had ever run `cargo doc`, so 16 warnings had collected. Four were links to items that do not exist, and two of those were worse than a dead link: `git_badge` and `info_chip` documented their sizes in terms of `PANEL_TEXT` and `PANEL_TEXT_META`, px constants deleted when the interface font scale landed. The module comment twenty lines up already says they went; the prose downstream still derived pixel arithmetic from them, so a reader was being told the pill is 20px tall against a 19px neighbour when both are now rems that move with `ui_font_size`. Rewritten against the ladder that exists (`META_MONO` beside `TEXT_MONO`), and `info_chip`'s comment now records what its own numbers imply: its padding and radius are pixels wrapped around rem-sized text, so the two stop agreeing once the interface scale leaves 100% — the same trap `PIP_SIZE` right below it is written in rems to avoid. Left as a note rather than changed, because that is a visual decision and this cannot see the result. The other ten are `private_intra_doc_links`, and that lint does not apply here: it exists so a *published* crate does not ship docs whose links dead-end, and all four crates are `publish = false`. Allowed at the crate root with that reason, because a public item explaining how it relates to a private one is the useful half of these comments. The `clippy` job becomes `lint` and runs rustdoc too, on the same warm cache. Still non-required. 2932 tests pass.
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
