# 設定

cmux 從 Ghostty 設定檔讀取設定，如果你是從 Ghostty 轉過來的，會覺得很熟悉。

## 設定檔位置

cmux 會依序在以下位置尋找設定：

1.  `~/.config/ghostty/config`
2.  `~/Library/Application Support/com.mitchellh.ghostty/config`

如果設定檔不存在，請建立它：

```
mkdir -p ~/.config/ghostty
touch ~/.config/ghostty/config
```

## 範例設定

~/.config/ghostty/config

```
font-family = SF Mono
font-size = 13
sidebar-font-size = 14
surface-tab-bar-font-size = 11
theme = One Dark
scrollback-limit = 50000000
split-divider-color = #3e4451
working-directory = ~/code
```

## cmux.json

cmux keeps app-owned settings, shortcuts, actions, custom commands, and workspace layouts in `~/.config/cmux/cmux.json`. Terminal rendering still lives in Ghostty config. On launch, if the file is missing, cmux writes a commented template there.

Open cmux Settings, then use the `cmux.json` section to open the canonical file in your preferred text editor.

1.  `~/.config/cmux/cmux.json`
2.  `.cmux/cmux.json` in a project for project-scoped actions and workspace commands

**Precedence:** global `~/.config/cmux/cmux.json` settings override values saved in the Settings window. Legacy `~/.config/cmux/settings.json` and Application Support settings files are read only as fallback for missing settings keys. Project-local `.cmux/cmux.json` can override actions, commands, UI action wiring, and notification hooks, but not global app preferences.

**Reload:** edit the file, then use `Cmd+Shift+,` or `cmux reload-config` to re-read it without restarting the app.

**Migrations:** keep `schemaVersion` at `1` for now. Future cmux versions will use that field for upgrades. If cmux sees a newer schema version, it logs a warning and parses known keys only.

The file accepts JSON with comments and trailing commas. The canonical schema is published at [https://raw.githubusercontent.com/manaflow-ai/cmux/main/web/data/cmux.schema.json](https://raw.githubusercontent.com/manaflow-ai/cmux/main/web/data/cmux.schema.json) and the source lives at [https://github.com/manaflow-ai/cmux/blob/main/web/data/cmux.schema.json](https://github.com/manaflow-ai/cmux/blob/main/web/data/cmux.schema.json).

### `terminal`

Terminal presentation settings from Settings > Terminal.

`terminal.adaptiveDefaultTheme`

為 true（預設）時，除非已設定 Ghostty 主題或終端機顏色，否則 cmux 會提供隨外觀變更的預設配色。字體和其他設定會保留。為 false 時，Ghostty 使用固定的內建配色。明確指定的主題和顏色一律優先，包括 theme = light:X,dark:Y。

Type

`boolean`

Default

`true`

`terminal.showScrollBar`

Show the right-edge terminal scroll bar when scrollback is available. cmux automatically suppresses it for alternate-screen style TUI surfaces.

Type

`boolean`

Default

`true`

`terminal.scrollSpeed`

調整每次滑鼠滾輪或觸控式軌跡板捲動事件讓終端機移動的距離。大於 1 的值會加快捲動，小於 1 的值會減慢捲動。

Type

`number`

Default

`1`

`terminal.sessionContentMaxWidth`

終端機與內建代理程式聊天內容的選用最大寬度，單位為點。設為 false 可使用整個窗格寬度。

Type

`boolean | number`

Default

`false`

`terminal.sessionContentAlignment`

啟用 sessionContentMaxWidth 時，終端機與內建代理程式聊天內容的水平位置。

Type

`string`

Default

`"center"`

Allowed values

`left, center, right`

`terminal.copyOnSelect`

為 true 時，選取確認後會將所選終端機文字複製到系統剪貼簿。為 false 時，cmux 不會輸出 Ghostty copy-on-select 覆寫；選取剪貼簿行為由 Ghostty 設定與預設值控制。

Type

`boolean`

Default

`false`

`terminal.showCopyConfirmation`

Briefly show "Copied to clipboard" at the bottom of a terminal after selecting text copies it. Applies whether copyOnSelect or Ghostty's copy-on-select turned copying on. Copies made with a keyboard shortcut or by a program (OSC 52) never show it.

Type

`boolean`

Default

`false`

`terminal.reflowHardWrapOnCopy`

When true, copying terminal text also joins a line that exactly fills the terminal width onto the next line, undoing hard wraps a program inserted at the grid edge. Soft-wrapped rows are always joined.

Type

`boolean`

Default

`false`

`terminal.confirmUnsafePaste`

When true, a paste that Ghostty's clipboard-paste-protection flags as unsafe (for example, text with a line break going to a program that has not enabled bracketed paste) waits for confirmation in a sheet attached to the terminal's window. When false, cmux pastes it without asking. OSC 52 clipboard reads are not affected.

Type

`boolean`

Default

`false`

`terminal.textEditingGestures`

Replay macOS text-editing gestures as line-editor keys at the shell prompt: Command and Option arrow keys move by line and word, and Command and Option Delete kill by line and word. While a full-screen application (vim, less, htop, tmux) has the terminal on the alternate screen, it gets the keys as if gestures were off, unless textEditingGesturesInFullScreenApps is on. Ghostty's own bindings still apply there, so Command+Left sends Ctrl+A and Option+Left sends Esc b.

Type

`boolean`

Default

`false`

`terminal.textEditingCommandMovesByWord`

With textEditingGestures on, switch to a browser-style layout: Command arrow and Delete keys move and delete by word, like Option, and Control+Left/Right move to the start and end of the line. Every other Control chord, including Ctrl+W and Ctrl+C, still reaches the terminal. macOS reserves Control+Left/Right for switching Spaces by default; turn those off in System Settings > Keyboard > Keyboard Shortcuts > Mission Control for Control+arrows to reach cmux.

Type

`boolean`

Default

`false`

`terminal.textEditingGesturesInFullScreenApps`

Keep textEditingGestures active while a full-screen application has the terminal on the alternate screen. tmux, screen, and zellij keep the outer terminal on the alternate screen even at their shell prompt, so turn this on to use gestures inside a multiplexer. Applications that bind the gesture chords themselves then receive the translated keys.

Type

`boolean`

Default

`false`

`terminal.showPasswordInputIndicator`

Show a lock badge in the terminal corner while the foreground program has turned echo off for a password prompt (sudo, ssh, passwd, gpg). cmux draws the badge itself and never changes terminal text. Only prompts on the local terminal are detected: an ssh password prompt counts, but sudo run inside an ssh session does not. Changes apply to an open prompt at once.

Type

`boolean`

Default

`true`

`terminal.showPasswordInputDots`

When the password input badge is shown, also draw one dot per typed character. cmux keeps only a count, never the typed characters. Backspace removes a dot; Enter or echo turning back on clears them. Pasted text is not counted.

Type

`boolean`

Default

`false`

`terminal.showJumpToBottomButton`

Removed. cmux no longer shows a Jump to Bottom button in terminal panes, and ignores this key. It stays in the schema so existing configs still validate.

Type

`boolean`

Default

`none`

`terminal.predictiveLocalEcho`

Draw typed characters immediately in a terminal whose shell runs on another machine (cmux ssh, Cloud, remote tmux) when the link is slow, underlined until the remote echo confirms them, and withdraw them if the remote disagrees. Local terminals, password prompts and full-screen apps are excluded.

Type

`boolean`

Default

`true`

`terminal.autoResumeAgentSessions`

Automatically run agent resume commands for restored terminal sessions when cmux reopens after quit. Set false to restore panes while keeping Claude Code, Codex, OpenCode, and other saved agent sessions idle until you resume them manually.

Type

`boolean`

Default

`true`

`terminal.showTextBoxOnNewTerminals`

預設在新建的工作區、終端機分頁和終端機分割中顯示TextBox 輸入。

Type

`boolean`

Default

`false`

`terminal.focusTextBoxOnNewTerminals`

預設在新建的工作區、終端機分頁和終端機分割中聚焦TextBox 輸入。聚焦也會顯示 TextBox。

Type

`boolean`

Default

`false`

`terminal.agentHibernation`

Routine Agent Hibernation settings. cmux kills idle background agent processes to free RAM and CPU, then resumes them with their saved session when their tab is visited. Routine hibernation requires a restorable coding agent whose lifecycle reports idle, an off-screen terminal, a live-terminal count above the configured limit, and unchanged output through the idle and confirmation windows. Independently, under memory pressure (critical pressure from macOS or from the cmux app's own footprint, or cmux's total memory use past its aggregate warning threshold) cmux may hibernate every safe idle background agent even when enabled is false; visible, running, needs-input, recently changed, and unprotectable agents remain excluded. The placeholder Resume button is a manual fallback.

Type

`object`

Default

`none`

`terminal.rendererRealization`

Reclaim off-screen terminal GPU renderer memory. cmux releases the Metal renderer (IOSurface) of a terminal that has stayed off-screen and idle while keeping its process and terminal state alive, then rebuilds the renderer instantly when the tab is visited again. Non-destructive and on by default.

Type

`object`

Default

`none`

`terminal.titleUpdates`

Terminal title update throttling and diagnostics.

Type

`object`

Default

`none`

`terminal.runawayMemoryGuardrail`

Per-pane process-tree memory monitoring.

Type

`object`

Default

`none`

`terminal.textBoxMaxLines`

Maximum number of lines the rich terminal TextBox input can grow to before it scrolls.

Type

`integer`

Default

`10`

`terminal.textBoxDefaultSubmitAction`

Default TextBox submit action ID for new terminal sessions. Use text-entry for plain input or one of the configured action IDs.

Type

`string`

Default

`"text-entry"`

`terminal.textBoxSubmitActions`

Configurable TextBox submit actions shown on the submit button, Shift-Tab cycle, and right-click menu.

Type

`array<object>`

Default

```
[]
```

`terminal.resumeCommands`

Signed command-prefix approvals for restoring non-agent terminal surfaces. cmux writes this list when you approve a surface resume command.

Type

`array<object>`

Default

```
[]
```

`terminal.uploadCommands`

Host-scoped rules that replace the built-in scp for terminal file drops and pastes over SSH. When the ssh destination matches a rule, cmux runs that rule's command once per file instead of scp, and inserts the command's stdout at the cursor (verbatim, with control characters stripped); if the command prints nothing, cmux inserts the shell-escaped remote path it chose instead. Per-file outputs are space-joined. First matching enabled rule wins; no match runs the built-in scp unchanged. A non-zero exit, timeout, or cancel inserts nothing.

Type

`array<object>`

Default

```
[]
```

### `notifications`

Notification behavior from Settings > Notifications.

`notifications.dockBadge`

Type

`boolean`

Default

`false`

`notifications.suppressOnlyFocusedSurface`

啟用後，只有當通知橫幅的 Surface 正好是目前聚焦的 Surface 時，該橫幅才會自動撤回。對於目前可見 workspace 中未聚焦的 Surface 所投遞的橫幅，在你聚焦該 Surface（或點擊／關閉它）之前會持續顯示，而不會在 workspace 變為可見時被撤回。關閉則保留舊有的基於 workspace 可見性的撤回行為。

Type

`boolean`

Default

`false`

`notifications.suppressWhenAppFocused`

啟用後，只要 cmux 是目前使用中的 App，cmux 就會對所有通知略過桌面橫幅，而不只限於取得焦點的窗格。通知仍會顯示在側邊欄中，音效與自訂指令也仍會執行，轉送到手機的行為不變。關閉時，即使 cmux 取得焦點，其他 workspace 與窗格的橫幅也會繼續顯示。

Type

`boolean`

Default

`false`

`notifications.agentPermissionPrompt`

Notify when an agent (e.g. Claude Code) is blocked waiting for your permission to run a tool. On by default, since this is the alert you must act on to unblock the agent.

Type

`boolean`

Default

`true`

`notifications.agentTurnComplete`

When to notify that an agent finished a turn. whenIdle (default) suppresses the notification while the agent still has a running background task or a pending scheduled wakeup, so you are pinged once work truly drains. always notifies on every turn end; never disables it.

Type

`string`

Default

`"whenIdle"`

Allowed values

`whenIdle, always, never`

`notifications.agentIdleReminder`

當代理程式閒置並等待你的輸入時（回合結束後約 60 秒）傳送通知。只要上一回合的背景工作仍在等待，就會抑制通知，避免正在執行的建置或監看程式觸發錯誤的等待提醒。

Type

### `shortcuts.when`

每個動作可選的內容述詞（VS Code 風格的 when 子句），依 cmux 動作 id 建立索引。只有在其子句成立時，綁定才會觸發，也只會在這種情況下與同一按鍵上的其他綁定衝突。省略子句即保留動作的內建內容。子句可用的詞彙：

-   `sidebarFocus`, `browserFocus`, `markdownFocus`, `filePreviewTextEditorFocus`, `simulatorFocus`, `terminalFocus`, `commandPaletteVisible`, `terminalFindVisible`, `terminalAlternateScreen`, `workspaceCanvasLayout` — 布林鍵。未知或不存在的鍵視為 false；也接受常值 true 和 false。
-   `sidebarMode` (`files`, `find`, `sessions`, `feed`, `dock`), `paneCount`, `workspaceCount` — 用於比較的型別化鍵：右側邊欄的目前模式（字串），以及窗格與工作區數量（整數）。
-   `!`, `&&`, `||`, `(…)`, `==`, `!=`, `=~`, `<`, `<=`, `>`, `>=`, `in [a, b]` — 布林運算子、型別化比較、正規表示式比對與清單成員判斷。比較的結合優先順序高於 && 和 ||。

例如，以下設定讓 Ctrl+1–9 在右側邊欄未取得焦點時選取工作區（將 Ctrl+1–5 留給側邊欄模式切換器），並在工作區有多個窗格時，將表面選取限制在尋找側邊欄：

```
"shortcuts": {
  "bindings": { "selectWorkspaceByNumber": "ctrl+1" },
  "when": {
    "selectWorkspaceByNumber": "!sidebarFocus",
    "selectSurfaceByNumber": "sidebarMode == 'find' && paneCount > 1"
  }
}
```
