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.

Metadata

$schema

Optional schema URL for editor completion and validation.

Type: string
Default: "https://raw.githubusercontent.com/manaflow-ai/cmux/main/web/data/cmux.schema.json"

schemaVersion

Schema version for forward-compatible migrations. Newer versions are parsed on a best-effort basis.

Type: boolean
Default: true

app.minimalMode

Hide the workspace title bar and move controls into the sidebar.

Type: boolean
Default: false

app.keepWorkspaceOpenWhenClosingLastSurface

When true, closing the last surface keeps the workspace open.

app.paneResizeStepPixels

Pixels moved per keypress when using pane-resize shortcuts. Accepts 1–200; defaults to 20. Changes apply immediately.

Type: integer
Default: 20

app.focusHistoryIncludesPanesAndTabs

When true, Back and Forward include focus changes between panes and tabs. When false, they navigate between workspaces only.

Type: boolean
Default: false

Type: string
Default: ""

app.openSupportedFilesInCmux

When enabled, Cmd-clicking readable local files opens supported previews in cmux, including text, code, PDFs, images, audio, video, and Quick Look files. Preview headers include an Open With menu based on the user's default and compatible macOS apps for that file.

Type: boolean
Default: true

app.openMarkdownInCmuxViewer

When enabled, Cmd-clicking .md/.markdown/.mkd/.mdx files opens the rendered cmux markdown viewer panel (with live reload) instead of the generic file preview.

Type: boolean
Default: true

app.globalFontMagnification

Zoom porcentual para todo lo que cmux dibuja por sí mismo: texto del terminal, títulos de pestañas, barras laterales, Settings, superposiciones y marco de la ventana. Las páginas web dentro de las superficies de navegador conservan su propio tamaño.

Type: integer
Default: 100

app.reorderOnNotification

Automatic workspace reordering. true or "notifications" moves workspaces with new notifications toward the top. "agentActivity" also moves them when a prompt is sent or an agent finishes a turn, needs input, or fails, at most once per burst and never while the pointer is over the sidebar. false or "off" keeps the order stable.

Type: boolean | string
Default: true

app.iMessageMode

Move a workspace to the top and show the submitted message when sending an agent prompt.

Type: boolean
Default: false

app.sendAnonymousTelemetry

Allow anonymous telemetry.

Type: boolean
Default: true

app.confirmQuit

Controla cuándo cmux pide confirmación antes de salir. Las compilaciones DEV siempre se cierran inmediatamente sin importar esta opción. El app.warnBeforeQuit heredado aún se acepta como alternativa booleana.

Default: true

app.warnBeforeClosingTabXButton

Mostrar una confirmación antes de cerrar una pestaña con el botón de cerrar pestaña.

Type: boolean
Default: false

app.warnBeforeClosingWorkspace

Show a confirmation before closing a workspace with a running process, or several workspaces at once. Pinned workspaces still ask when this is off.

Type: boolean

app.warnBeforeClosingWindow

Show a confirmation before closing a window with a running process, or all of a window's workspaces at once.

Type: boolean
Default: true

app.hideTabCloseButton

Ocultar los botones de cerrar pestaña en la barra de pestañas del panel.

Type: boolean
Default: false

app.tabBarVisibility

Determina cuándo un panel dibuja su barra de pestañas. "always" la dibuja incluso en un panel con una sola pestaña; "multiple-tabs" la oculta mientras el panel tenga una sola pestaña y la dibuja en cuanto se abre una segunda. El modo mínimo (app.minimalMode) la dibuja siempre, porque allí la barra de pestañas del panel superior hace también de barra de título de la ventana.

Type: string
Default: "always"
Allowed values: always, multiple-tabs

app.renameSelectsExistingName

Select the current name when opening rename flows.

Type: boolean
Default: true

app.commandPaletteSearchesAllSurfaces

Search every surface in the command palette switcher instead of only the active workspace.

Type: boolean
Default: false

`terminal`

Terminal presentation settings from Settings > Terminal.

terminal.adaptiveDefaultTheme

Cuando es true (predeterminado), cmux proporciona una paleta predeterminada que se adapta a la apariencia, salvo que se configure un tema de Ghostty o colores del terminal. Se conservan la fuente y los demás ajustes. Cuando es false, Ghostty usa su paleta integrada fija. Los temas y colores explícitos siempre tienen prioridad, incluido 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

Ajusta cuánto se mueve el terminal con cada evento de desplazamiento de la rueda del ratón o del trackpad. Los valores mayores que 1 aceleran el desplazamiento y los menores que 1 lo ralentizan.

Type: number
Default: 1

terminal.sessionContentMaxWidth

Ancho máximo opcional, en puntos, para el contenido del terminal y del chat de agente integrado. Establece false para usar todo el ancho del panel.

Type: boolean | number
Default: false

terminal.sessionContentAlignment

Posición horizontal del contenido del terminal y del chat de agente integrado cuando sessionContentMaxWidth está activado.

Type: string
Default: "center"
Allowed values: left, center, right

terminal.copyOnSelect

Cuando es true, copia el texto seleccionado del terminal al portapapeles del sistema cuando se confirma la selección. Cuando es false, cmux no emite una anulación de copy-on-select de Ghostty; la configuración y los valores predeterminados de Ghostty controlan el comportamiento del portapapeles de selección.

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

Muestra la entrada TextBox de forma predeterminada en espacios de trabajo, pestañas y divisiones de terminal recién creados.

Type: boolean
Default: false

terminal.focusTextBoxOnNewTerminals

Enfoca la entrada TextBox de forma predeterminada en espacios de trabajo, pestañas y divisiones de terminal recién creados. Enfocar también muestra 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

Show the unread count in the Dock tile.

Type: boolean
Default: true

notifications.showInMenuBar

Show the menu bar extra.

Type: boolean
Default: true

Default: true

notifications.paneFlashThemeColor

Use the terminal theme foreground for flashes when paneFlashColor is unset. Unread rings remain cmux blue.

Type: boolean
Default: false

notifications.paneFlashColor

Override the pane flash and unread notification ring color. Leave unset to use the accent from app.accentColor.

Type: unknown
Default: null

notifications.soundWhenFocused

Reproduce el sonido de notificación incluso cuando el panel que notificó ya tiene el foco. Desactivado de forma predeterminada, así que un panel con foco solo muestra su anillo y destello.

Type: boolean
Default: false

notifications.suppressOnlyFocusedSurface

Cuando está activado, un banner de notificación se retira automáticamente solo cuando su superficie es exactamente la superficie enfocada. Un banner entregado para una superficie no enfocada en el workspace actualmente visible permanece visible hasta que enfoques esa superficie (o hagas clic en él/lo descartes), en lugar de retirarse cuando el workspace se vuelve visible. Desactivado conserva el comportamiento heredado de retirada según la visibilidad del workspace.

Type: boolean
Default: false

notifications.suppressWhenAppFocused

Cuando está activado, cmux omite el banner de escritorio para todas las notificaciones mientras cmux es la app activa, no solo para el panel enfocado. Las notificaciones siguen apareciendo en la barra lateral, el sonido y el comando personalizado se siguen ejecutando, y el reenvío al teléfono no cambia. Desactivado sigue mostrando banners de otros workspaces y paneles mientras cmux tiene el foco.

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

Notifica cuando un agente ha estado inactivo esperando tu entrada (unos 60 segundos después de terminar un turno). Se suprime mientras siga pendiente el trabajo en segundo plano del turno anterior, para que una compilación o un monitor en ejecución no active una alerta de espera falsa.

Type: boolean
Default: true

notifications.sound

Notification sound preset.

Type: string
Default: "default"
Allowed values: default, Basso, Blow, Bottle, Frog, Funk, Glass, Hero, Morse, Ping, Pop, Purr, Sosumi, Submarine, Tink, custom_file, none

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, filePreviewTextEditorFocus, simulatorFocus, terminalFocus, commandPaletteVisible, terminalFindVisible, terminalAlternateScreen, 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.

`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, filePreviewTextEditorFocus, simulatorFocus, terminalFocus, commandPaletteVisible, terminalFindVisible, terminalAlternateScreen, 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"
  }
}
