jieba's dictionary costs ~55 MB resident and ~130 ms to build, and it was built eagerly on every terminal-view creation regardless of the `smart_select` setting or whether the user ever selects CJK text. macOS already ships a Chinese lexicon in CFStringTokenizer that matches jieba on most prose, is locale-independent (identical output for current / NULL / zh_CN / en_US), and segments Japanese and Korean properly where jieba shreds them into single characters. Make the OS tokenizer the primary path and keep jieba only as the fallback for platforms with no such API: - gate the dependency behind `cfg(not(target_os = "macos"))` so the embedded dictionary isn't even linked into the macOS build - never warm eagerly; the first CJK double-click kicks the build off in the background and settles for the unsegmented run, so the UI thread never blocks on it - skip jieba for runs containing kana or hangul, where selecting the whole run beats per-character tokens Also honor `Config::smart_select` in the prompt's command editor, which did bracket pairing, CJK segmentation and mixed-script narrowing even with the Settings toggle off.
tty7
A terminal workbench: shells, sessions, SSH, coding agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Sessions persist — quit or reboot; your shells keep running, no tmux
- Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
- Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume

Benchmarks
Same machine, same day, same 155×40 grid — Apple M1 Pro, macOS 26.3.1, five-run averages (2026-07-04):
