* fix(icons): draw the plus on the same optical bound as the rest of the set Every icon tty7 draws itself sits on one optical bound: 3.4..20.6 of a 24 viewBox, 19.3 units of ink once the round caps are counted. `plus` was the exception at 6..18, 14.1 units — 59% of the box where the rest fill 77-80%, and tighter even than the stock lucide glyph it replaced. That was compensated at the call site instead, by handing the three chrome tiles that carry a `+` a 16px glyph (`TILE_GLYPH_LINE`) where every other tile in the same row gets 13. It worked where it was applied and nowhere else: the port-forward section's `+` sits in a 24px tile, which has no `_LINE` step to grow into, so it rendered at 7.6px of ink against the 10.5px of the icons around it. Redraw the asset onto the bound and the compensation is no longer needed anywhere — the three call sites go back to plain `chrome_tile`, and the 24px tile is fixed for free. Scaling a glyph up buys stroke as well as extent, which is the part that is easy to miss: at 16px the old art also drew 16/13 wider, so moving the `+` to 13px thinned it by a fifth even as it got longer. A cross is two hairlines with no fill to hide behind, so the weight had to come back in the art's own `stroke-width`, and the value is eyeballed rather than derived — 1.0 CSS px reads thin against the closed shapes beside it, 2.0 reads heavy-handed, and 1.75 is where it settled after walking the range on a 2x screen. `TILE_GLYPH_LINE` stays for stock lucide `close`, which has the same tight geometry and is not ours to redraw. * fix(icons): keep the plus's extra weight to the 16/13 the call site was buying The redraw put `plus` on the family's optical bound and then took its `stroke-width` to 3.2308 — 1.75 CSS px at a 13px glyph, settled by eye against `panel-left`, `panel-right` and `ellipsis` in the titlebar row. Those are the three call sites the redraw was checked at, and they are the three whose neighbours are closed shapes carrying solid fills. The other three are not: - Source Control's row strip draws `plus` (Stage) directly beside stock `undo-2` (Discard) at an 11px glyph, and pairs it with stock `minus` (Unstage) one group up. Both stock glyphs stroke 2. At 3.2308 the `+` came out 1.48 CSS px against their 0.92 — the stage button reads as the emphasised one in a strip where nothing is emphasised, and a stage/unstage pair stops looking like a pair. - The switcher's Add SSH Host row draws it at 16px in the same gutter column as `search`, which is ours and strokes 2.1. - Settings → SSH puts it next to stock `search` and stock `ellipsis`. Reading a size heavy is the same failure as reading a size small, so the weight goes to the one value that is derived rather than chosen: 2.1 × 16/13 = 2.5846, the family's own stroke times the scale-up the three chrome tiles were already applying. At `TILE_GLYPH` that renders at 1.4 CSS px, which is exactly what the titlebar `+` has always drawn at — so nothing that was verified on screen moves, and the three tiles that never had a `_LINE` step to grow into stop being overdrawn. The arm ends move to 4.9846..19.0154 to keep the round-cap tips on whole pixels at the new weight; the ink extent is unchanged at 16.6. The test now derives the weight from `panel-left`'s own `stroke-width` instead of carrying an eyeballed band, and checks both arms rather than the vertical one — a cross edited on one axis passed before. --------- 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
