#配置

cmux 从 Ghostty 配置文件中读取配置，如果你之前使用 Ghostty，这些选项会很熟悉。

#配置文件位置

cmux 按以下顺序查找配置：

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

如果配置文件不存在，请创建：

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

#配置示例

~/.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 and the source lives at https://github.com/manaflow-ai/cmux/blob/main/web/data/cmux.schema.json.

#shortcuts.when

每个操作可选的上下文谓词（VS Code 风格的 when 子句），按 cmux 操作 id 索引。只有当其子句成立时，绑定才会触发，也只会在这种情况下与同一按键上的其他绑定冲突。省略子句即保留操作的内置上下文。子句可用的词汇：

  • sidebarFocus, browserFocus, markdownFocus, terminalFocus, commandPaletteVisible, terminalFindVisible, workspaceCanvasLayout — 布尔键。未知或不存在的键按 false 处理；也接受字面量 true 和 false。
  • sidebarMode (files, find, sessions, feed, dock), paneCount, workspaceCount — 用于比较的类型化键：右侧边栏的当前模式（字符串），以及窗格和工作区数量（整数）。
  • !, &&, ||, (…), ==, !=, =~, <, <=, >, >=, in [a, b] — 布尔运算符、类型化比较、正则匹配和列表成员判断。比较的结合优先级高于 && 和 ||。

例如，下面的配置让 Ctrl+1–9 在右侧边栏未聚焦时选择工作区（把 Ctrl+1–5 留给侧边栏模式切换器），并在工作区有多个窗格时将表面选择限定在查找侧边栏：

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