# Configuração

O cmux lê a configuração dos arquivos de configuração do Ghostty, oferecendo opções familiares se você vem do Ghostty.

## Locais do arquivo de configuração

O cmux procura configuração nestes locais (em ordem):

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

Crie o arquivo de configuração se ele não existir:

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

## Exemplo de configuração

~/.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).

## Schema reference

This reference covers every supported global settings key in `cmux.json`. The embedded browser, terminal, sidebar, notifications, automation, and cmux-owned keyboard shortcuts all live here. Actions and workspace commands are documented on the [custom commands page](https://cmux.com/pt-BR/docs/custom-commands).

Type

`integer`

Default

`100`

`app.reorderOnNotification`

Automatic workspace reordering. true or "notifications" moves workspaces with new notifications toward the top.

Mostrar uma confirmação antes de fechar uma aba com o botão de fechar aba.

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`

Default

`true`

`app.warnBeforeClosingWindow`

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

Type

`boolean`

`app.hideTabCloseButton`

Ocultar os botões de fechar aba na barra de abas do painel.

Type

`boolean`

Default

`false`

`app.tabBarVisibility`

Determina quando um painel desenha sua barra de abas. "always" a desenha mesmo em um painel com uma única aba; "multiple-tabs" a oculta enquanto o painel tiver uma única aba e a desenha assim que uma segunda for aberta. O modo mínimo (app.minimalMode) a desenha sempre, porque nele a barra de abas do painel superior também serve de barra de título da janela.

Type

`boolean`

Default

`false`

### `terminal`

Terminal presentation settings from Settings > Terminal.

`terminal.adaptiveDefaultTheme`

Quando true (padrão), o cmux fornece uma paleta padrão que se adapta à aparência, a menos que um tema do Ghostty ou cores do terminal estejam configurados. A fonte e as outras configurações são preservadas. Quando false, o Ghostty usa sua paleta integrada fixa. Temas e cores explícitos sempre têm prioridade, incluindo 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`

Define quanto o terminal se move a cada evento de rolagem da roda do mouse ou do trackpad. Valores acima de 1 aceleram a rolagem e valores abaixo de 1 a tornam mais lenta.

Type

`number`

Default

`1`

`terminal.sessionContentMaxWidth`

Largura máxima opcional, em pontos, para o conteúdo do terminal e do chat integrado do agente. Defina como false para usar toda a largura do painel.

Type

`boolean | number`

Default

`false`

`terminal.sessionContentAlignment`

Posicionamento horizontal do conteúdo do terminal e do chat integrado do agente quando sessionContentMaxWidth está ativado.

Type

`string`

Default

`"center"`

Allowed values

`left, center, right`

`terminal.copyOnSelect`

Quando true, copia o texto selecionado no terminal para a área de transferência do sistema quando a seleção é confirmada. Quando false, o cmux não emite uma substituição copy-on-select do Ghostty; a configuração e os padrões do Ghostty controlam o comportamento da área de transferência de seleção.

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`

Mostra a entrada TextBox por padrão em áreas de trabalho, abas e divisões de terminal recém-criadas.

Type

`boolean`

Default

`false`

`terminal.focusTextBoxOnNewTerminals`

Foca a entrada TextBox por padrão em áreas de trabalho, abas e divisões de terminal recém-criadas. Focar também mostra o 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`

`notifications.soundWhenFocused`

Reproduz o som de notificação mesmo quando o painel que notificou já está em foco. Desativado por padrão, então um painel em foco mostra apenas o anel e o destaque.

Type

`boolean`

Default

`false`

`notifications.suppressOnlyFocusedSurface`

Quando ativado, um banner de notificação é retirado automaticamente apenas quando sua superfície é exatamente a superfície focada. Um banner entregue para uma superfície não focada no workspace atualmente visível permanece visível até você focar essa superfície (ou clicar nele/dispensá-lo), em vez de ser retirado quando o workspace se torna visível. Desativado preserva a retirada antiga baseada na visibilidade do workspace.

Type

`boolean`

Default

`false`

`notifications.suppressWhenAppFocused`

Quando ativado, o cmux ignora o banner da área de trabalho em todas as notificações enquanto o cmux é o app ativo, não apenas no painel em foco. As notificações continuam aparecendo na barra lateral, o som e o comando personalizado continuam sendo executados, e o encaminhamento para o celular não muda. Desativado continua mostrando banners de outros workspaces e painéis enquanto o cmux está em 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`

Notifique quando um agente estiver ocioso aguardando sua entrada (cerca de 60 segundos após o fim de um turno). A notificação é suprimida enquanto ainda houver trabalho em segundo plano do turno anterior, para que um build ou monitor em execução não gere um falso alerta de espera.

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`

`notifications.customSoundFilePath`

Local path to the custom notification sound file.

Type

`string`

Chaves booleanas: sidebarFocus, browserFocus, markdownFocus, filePreviewTextEditorFocus, simulatorFocus, terminalFocus, commandPaletteVisible, terminalFindVisible, terminalAlternateScreen, workspaceCanvasLayout. Chaves tipadas aceitam comparações: a string sidebarMode (files, find, sessions, feed ou dock) e os inteiros paneCount e workspaceCount. Os operadores de comparação são ==, !=, =~ (expressão regular), <, <=, >, >= e \`in \[a, b\]\`; uma chave desconhecida ou ausente é avaliada como false. Os literais booleanos true e false também são aceitos; \`key == false\` equivale a \`!key\`. O atalho da ação só dispara (e só conflita com outros atalhos) quando a cláusula é verdadeira. Exemplos: { "selectWorkspaceByNumber": "!sidebarFocus" } seleciona workspaces com Ctrl+1–9 em todos os lugares, exceto quando a barra lateral direita está em foco; { "selectSurfaceByNumber": "sidebarMode == 'find' && paneCount > 1" } restringe uma atribuição à barra lateral Localizar quando o workspace tem vários painéis.

### `shortcuts.when`

Predicados de contexto opcionais por ação (cláusulas when no estilo do VS Code), indexados pelo id da ação do cmux. Uma atribuição só dispara — e só conflita com outra atribuição na mesma tecla — quando sua cláusula é verdadeira. Omita a cláusula para manter o contexto integrado da ação. O vocabulário das cláusulas:

-   `sidebarFocus`, `browserFocus`, `markdownFocus`, `filePreviewTextEditorFocus`, `simulatorFocus`, `terminalFocus`, `commandPaletteVisible`, `terminalFindVisible`, `terminalAlternateScreen`, `workspaceCanvasLayout` — chaves booleanas. Uma chave desconhecida ou ausente é avaliada como false; os literais true e false também são aceitos.
-   `sidebarMode` (`files`, `find`, `sessions`, `feed`, `dock`), `paneCount`, `workspaceCount` — chaves tipadas para comparações: o modo ativo da barra lateral direita (string) e as contagens de painéis e workspaces (inteiros).
-   `!`, `&&`, `||`, `(…)`, `==`, `!=`, `=~`, `<`, `<=`, `>`, `>=`, `in [a, b]` — operadores booleanos, comparações tipadas, correspondência por regex e pertinência a listas. Comparações ligam mais forte que && e ||.

Por exemplo, isto faz Ctrl+1–9 selecionar workspaces em todos os lugares, exceto quando a barra lateral direita está em foco (deixando Ctrl+1–5 para o seletor de modo da barra lateral), e restringe a seleção de superfície à barra lateral Localizar quando o workspace tem vários painéis:

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