Add One Dark Pro as a ninth built-in, slotted alphabetically among the dark themes: background #282c34, foreground #abb2bf, the classic One Dark syntax palette for the normal ANSI slots and One Dark Pro's bright variants for the bright ones. Two seeds deliberately diverge from the VS Code theme's terminal set: * The accent is the editor cursor/focus blue #528bff, not the syntax blue #61afef — the accent doubles as the switch's checked track, and #61afef sits at the same luminance as the #abb2bf knob (1.11:1). * The normal red is the classic #e06c75, not the Pro terminal #e05561 — conditioned for AA the latter lands within 37 channel-distance of the orange-yellow #d18f52, under the 40 separability floor danger/warning must clear. Also bumps the theme count in README and docs (eight → nine).

# Features
|
||
|
||
<sub>English · [简体中文](features.zh-CN.md)</sub>
|
||
|
||
## Input
|
||
|
||
- **Ghost suggestions** — your history completes the whole line as you type; <kbd>→</kbd> to accept
|
||
- **Explained tab completion** — every flag and subcommand with its description, for ~100 common commands; when tty7 has nothing to offer the Tab falls through to your shell's own completion, and the whole feature can be turned off (Settings → Terminal → Keyboard, or `tab_completion` in `config.json`)
|
||
- **Syntax highlighting** — as you type, nothing to install
|
||
- **Fuzzy history search** — <kbd>⌃ R</kbd> shows what you ran, where, and whether it failed; turn it off (Settings → Terminal → Keyboard, or `history_search` in `config.json`) and <kbd>⌃ R</kbd> goes to your shell instead, so an fzf / percol binding keeps working
|
||
- **History from day one** — your existing shell history works as-is and carries across sessions
|
||
- **Line editing** — click to place the caret, mouse selection, word motion, undo
|
||
- **Multi-line editing** — wrapped and multi-line commands edit in place; the grid shifts to keep the caret visible
|
||
|
||
## In the window
|
||
|
||
- **Tabs & splits** — always open in the current directory
|
||
- **Repo-grouped sidebar** — the left tab sidebar groups rows under a header per git repository, non-repo tabs in a trailing *Scratch* section; branch switches and in-repo `cd`s never move a row (`sidebar_grouping` in `config.json`: `repo` default, `none` for a flat list)
|
||
- **Command palette** <kbd>⌘ P</kbd> · scrollback search <kbd>⌘ F</kbd>
|
||
- **⌘/Ctrl-click links** (⌘ on macOS, Ctrl on Windows/Linux) · desktop notifications · copy on select (opt-in, Settings → Terminal → Clipboard)
|
||
- **Smart double-click selection** — double-click grabs the whole URL, file path, bracket/quote pair, or dictionary-segmented CJK word under the cursor; Shift-click extends a selection (toggle in Settings → Terminal → Mouse; word separators via `word_separators` in `config.json`)
|
||
- **Nine themes, plus your own** — YAML seed themes with solid, gradient, or image backgrounds; iTerm2 `.itermcolors` import; in-app color editor with a background-image picker
|
||
- **Sync with system** — Settings → Appearance; pick separate light and dark themes and tty7 follows the OS appearance live (`theme_follow_system`, `theme_preset_light` / `theme_preset_dark` in `config.json`)
|
||
- **Window opacity & blur** — Settings → Appearance → Window; applies to every theme, *Follow theme* returns to the theme's own `opacity` / `blur`
|
||
- **CJK / IME input**
|
||
|
||
## Fonts
|
||
|
||
- **Hack is bundled** — it ships inside the binary, so the default renders identically everywhere without relying on a system install
|
||
- **Primary + ordered fallbacks** — `font_family` and `font_fallbacks` in `config.json`; optional `font_family_bold` / `font_family_italic` for distinct faces, and `font_features` to pass OpenType features through (contextual ligatures stay off unless you ask for them)
|
||
- **Platform-aware defaults** — the fallback list names faces the host OS actually ships (PingFang SC / Apple Color Emoji on macOS, Microsoft YaHei / Segoe UI Emoji on Windows, Noto on Linux). Those stock names are appended to a hand-written list too, so a `config.json` written on another platform still resolves
|
||
|
||
### CJK and the two-column grid
|
||
|
||
A cell is one advance of the primary face, and a wide (CJK) character is pinned
|
||
to exactly two of them. A CJK fallback therefore sits flush in its slot only if
|
||
its ideographs advance **twice** the primary's Latin advance.
|
||
|
||
Bundled Hack advances 0.60205em, so a two-column slot is 1.2041em — while every
|
||
stock CJK face (Microsoft YaHei, PingFang SC, Noto Sans CJK) advances 1.0em.
|
||
Those glyphs get left-aligned in the slot and the leftover ~0.2em lands as a gap
|
||
on the right of every character.
|
||
|
||
[Maple Mono NF CN](https://github.com/subframe7536/maple-font) is tried first on
|
||
every platform for exactly this reason — 0.6em Latin, 1.2em CJK, an exact
|
||
two-cell fit against Hack. It is referenced by name only, never bundled (~20MB
|
||
per weight): install it and tty7 picks it up with no config change.
|
||
|
||
For CJK set *tight* rather than merely even, change the primary face instead —
|
||
one that advances 0.5em (Sarasa Mono SC, say) makes two columns exactly 1.0em.
|
||
|
||
## Coding agents
|
||
|
||
tty7 recognizes third-party coding agents running in a pane (Claude Code,
|
||
Codex, Gemini CLI, Aider, Amp, OpenCode, and ~10 more) and adds around them —
|
||
it never wraps or replaces the agent.
|
||
|
||
- **Brand avatars** — the tab chip / sidebar row shows which agent runs where; custom wrappers map in via `agent_commands` in `config.json`
|
||
- **Status dot** — working (blue) / needs your input (amber) / done (green), driven by agent-reported events over an OSC channel; Settings → Agents installs the hooks that feed it (Claude Code, Codex, Copilot CLI, OpenCode, Pi, Grok Build)
|
||
- **Notifications** — "needs your permission…" the moment an agent blocks on you, and "finished after Ns" per turn, honoring your notification policy
|
||
- **Branch at a glance** — each sidebar row shows its pane's git branch and working-tree diff (`+N −M`), refreshed on `cd` and when a command finishes
|
||
- **Session resume** — panes lost to a reboot re-launch their agent conversation on restore, carrying the original launch flags (`claude --dangerously-skip-permissions --resume …`) (`restore_agent_sessions`, on by default)
|
||
- **Context feed** — palette commands send the current selection or the repo's `git diff` to the running agent as a ready-made prompt
|
||
- **Tray icon** — a system tray / menu bar item that flips to an attention state the moment any agent needs your input; its menu lists every agent pane (brand avatar + status dot, click to reveal), switches the notification policy, and offers *Quit and Stop Daemon* alongside the plain session-keeping quit (`show_tray_icon`, on by default)
|
||
|
||
## SSH
|
||
|
||
A native Rust SSH stack (russh) is the **only** path — profiles, credentials,
|
||
and SFTP without shelling out to `ssh`. There is no system-ssh compat mode.
|
||
|
||
- **QuickConnect** — type `user@host[:port]` in the palette and connect; IPv6 `[::1]:port` supported
|
||
- **Saved profiles** — full connection config with passwords / passphrases in the OS keychain, never on disk
|
||
- **`~/.ssh/config` aliases** — type one to connect (resolved natively — common fields, best-effort — over russh), or import them as profiles in Settings
|
||
- **GUI auth** — in-pane sheets for password, key passphrase, 2FA, and host-key confirmation (new vs. changed)
|
||
- **Built-in SFTP** — a slide-in file panel: browse, upload / download, rename / delete / chmod, drag to Finder
|
||
- **Port forwarding** — Local / Remote / Dynamic, preconfigured or added live, plus ⌘/Ctrl-click `localhost:PORT` to auto-forward
|
||
- **Jump hosts & proxies** — multi-hop via profile references or `ProxyJump`, ProxyCommand, SOCKS5 / HTTP
|
||
|
||
| Entry point | Connects via |
|
||
|---|---|
|
||
| Saved profiles · QuickConnect · typed `user@host[:port]` | Native russh — SFTP · keychain · GUI auth · L/R/D forwards |
|
||
| `~/.ssh/config` aliases | Resolved natively, then russh (`Match`/canonicalize/GSSAPI unsupported — no fallback) |
|
||
|
||
## Keybindings
|
||
|
||
Keys are shown in macOS notation — on Windows and Linux, read <kbd>⌘</kbd> as
|
||
<kbd>Ctrl</kbd>. The essentials:
|
||
|
||
| | |
|
||
|---|---|
|
||
| <kbd>⌘ T</kbd> · <kbd>⌘ W</kbd> · <kbd>⌘ ⇧ T</kbd> | new tab · close tab · reopen closed tab |
|
||
| <kbd>⌘ 1</kbd>…<kbd>⌘ 9</kbd> · <kbd>⌃ ⇥</kbd> · <kbd>⌃ ⇧ ⇥</kbd> | jump to tab 1–9 · next tab · previous tab |
|
||
| <kbd>⌘ D</kbd> · <kbd>⌘ ⇧ D</kbd> | split right · split down |
|
||
| <kbd>⌘ ]</kbd> · <kbd>⌘ [</kbd> | next pane · previous pane |
|
||
| <kbd>⌘ ⌥ ←→↑↓</kbd> | focus the pane in that direction |
|
||
| <kbd>⌘ ⏎</kbd> · <kbd>⌘ ⇧ ⏎</kbd> | toggle fullscreen · maximize / restore the pane |
|
||
| <kbd>⌘ K</kbd> | clear the screen and scrollback |
|
||
| <kbd>⌘ P</kbd> | command palette |
|
||
| <kbd>⌘ F</kbd> | search the scrollback |
|
||
| <kbd>⌃ R</kbd> | fuzzy-search shell history |
|
||
| <kbd>⌘ +</kbd> · <kbd>⌘ −</kbd> · <kbd>⌘ 0</kbd> | font size up · down · reset |
|
||
|
||
**Settings → Keybindings** (<kbd>⌘ ,</kbd>) lists every shortcut. Click one,
|
||
press the new keys (<kbd>Esc</kbd> cancels, <kbd>Backspace</kbd> resets to
|
||
default), and it takes effect immediately. Pane resize and swap have no default
|
||
keys — bind them here or run them from the command palette.
|
||
|
||
**tmux preset** — remaps pane/tab actions onto a prefix (default <kbd>⌃ B</kbd>):
|
||
<kbd>⌃ B</kbd> <kbd>C</kbd> opens a tab, <kbd>⌃ B</kbd> <kbd>%</kbd> splits,
|
||
<kbd>⌃ B</kbd> then an arrow moves focus. A bare prefix reaches the shell after
|
||
a brief pause; `prefix` + an unbound key passes straight through.
|
||
|
||
## Performance notes
|
||
|
||
- The PTY is read at device speed and parsed in large batches, off the render path
|
||
- Hot paths are lock-free — a big `cat` never waits on drawing
|
||
- The daemon buffers up to 16 MiB ahead of the window before backpressure applies
