#Configuración

cmux lee la configuración de archivos de configuración de Ghostty, ofreciéndole opciones familiares si viene de Ghostty.

#Ubicaciones del archivo de configuración

cmux busca configuración en estas ubicaciones (en orden):

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

Cree el archivo de configuración si no existe:

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

#Configuración de ejemplo

~/.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.

~/.config/cmux/cmux.json
.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`

shortcuts.when

Predicados de contexto opcionales por acción (cláusulas `when` al estilo de VS Code), indexados por el id de acción de cmux. Cada valor es una expresión booleana sobre claves de contexto, combinada con !, &&, || y paréntesis. Claves booleanas: sidebarFocus, browserFocus, markdownFocus, terminalFocus, commandPaletteVisible, terminalFindVisible, workspaceCanvasLayout. Las claves tipadas admiten comparaciones: la cadena sidebarMode (files, find, sessions, feed o dock) y los enteros paneCount y workspaceCount. Los operadores de comparación son ==, !=, =~ (expresión regular), <, <=, >, >= e `in [a, b]`; una clave desconocida o ausente se evalúa como false. También se aceptan los literales booleanos true y false; `key == false` equivale a `!key`. El atajo de la acción solo se activa (y solo entra en conflicto con otros atajos) cuando la cláusula se cumple. Ejemplos: { "selectWorkspaceByNumber": "!sidebarFocus" } selecciona espacios de trabajo con Ctrl+1–9 en todas partes excepto cuando la barra lateral derecha tiene el foco; { "selectSurfaceByNumber": "sidebarMode == 'find' && paneCount > 1" } limita una asignación a la barra lateral de búsqueda cuando el espacio de trabajo tiene varios paneles.

Type: object

#`shortcuts.bindings`

Use a string for a single shortcut, a two-item array for a chord, or null to unbind a shortcut in shortcuts.bindings. Unbind aliases also include empty string (""), none, clear, unbound, and disabled. Example chord: ["ctrl+b", "c"]. Numbered actions use 1 as the stored default and still match digits 1 through 9.

#`shortcuts.when`

Predicados de contexto opcionales por acción (cláusulas when al estilo de VS Code), indexados por el id de acción de cmux. Una asignación solo se activa —y solo entra en conflicto con otra asignación de la misma pulsación— cuando su cláusula se cumple. Omite la cláusula para conservar el contexto integrado de la acción. El vocabulario de las cláusulas:

sidebarFocus, browserFocus, markdownFocus, terminalFocus, commandPaletteVisible, terminalFindVisible, workspaceCanvasLayout — claves booleanas. Una clave desconocida o ausente se evalúa como false; también se aceptan los literales true y false.
sidebarMode (files, find, sessions, feed, dock), paneCount, workspaceCount — claves tipadas para comparaciones: el modo activo de la barra lateral derecha (cadena) y los recuentos de paneles y espacios de trabajo (enteros).
!, &&, ||, (…), ==, !=, =~, <, <=, >, >=, in [a, b] — operadores booleanos, comparaciones tipadas, coincidencia por expresión regular y pertenencia a listas. Las comparaciones ligan más fuerte que && y ||.

Por ejemplo, esto hace que Ctrl+1–9 seleccione espacios de trabajo en todas partes salvo cuando la barra lateral derecha tiene el foco (dejando Ctrl+1–5 libre para el selector de modo de la barra lateral), y limita la selección de superficie a la barra lateral de búsqueda cuando el espacio de trabajo tiene varios paneles:

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