# Konfigurasjon

cmux leser konfigurasjon fra Ghostty-konfigurasjonsfiler, slik at du får kjente alternativer hvis du kommer fra Ghostty.

## Plasseringer for konfigurasjonsfiler

cmux ser etter konfigurasjon på disse plasseringene (i rekkefølge):

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

Opprett konfigurasjonsfilen hvis den ikke finnes:

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

## Eksempelkonfigurasjon

~/.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).

Type

`integer`

Default

`100`

`app.reorderOnNotification`

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

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`

Default

`true`

`app.hideTabCloseButton`

Skjul lukkeknapper for faner i faneraden i ruten.

Type

`boolean`

Default

`false`

`app.tabBarVisibility`

Bestemmer når en rute tegner faneraden sin. "always" tegner den selv for en rute med bare én fane; "multiple-tabs" skjuler den så lenge ruten har én fane, og tegner den så snart en fane nummer to åpnes. Minimal modus (app.minimalMode) tegner den alltid, fordi faneraden til den øverste ruten der også fungerer som vinduets tittellinje.

Type

`string`

Default

`"always"`

Allowed values

`always, multiple-tabs`

`app.renameSelectsExistingName`

Select the current name when opening rename flows.

Type

`boolean`

Type

`boolean`

Default

`false`

### `terminal`

Terminal presentation settings from Settings > Terminal.

`terminal.adaptiveDefaultTheme`

Når true (standard), bruker cmux en standardpalett som følger utseendet, med mindre et Ghostty-tema eller terminalfarger er konfigurert. Skrifttype og andre innstillinger beholdes. Når false, bruker Ghostty sin faste innebygde palett. Eksplisitte temaer og farger har alltid prioritet, inkludert 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`

Skalerer hvor langt terminalen flytter seg for hver rullehendelse fra musehjul eller styreflate. Verdier over 1 gjør rullingen raskere, og verdier under 1 gjør den tregere.

Type

`number`

Default

`1`

`terminal.sessionContentMaxWidth`

Valgfri maksimal bredde i punkter for terminalinnhold og den innebygde agentchatten. Angi false for å bruke hele rutens bredde.

Type

`boolean | number`

Default

`false`

`terminal.sessionContentAlignment`

Vannrett plassering av terminalinnhold og den innebygde agentchatten når sessionContentMaxWidth er aktivert.

Type

`string`

Default

`"center"`

Allowed values

`left, center, right`

`terminal.copyOnSelect`

Når verdien er true, kopieres markert terminaltekst til systemutklippstavlen når markeringen bekreftes. Når verdien er false, sender ikke cmux ut en Ghostty copy-on-select-overstyring; Ghostty-konfigurasjon og standardverdier styrer oppførselen til markeringsutklippstavlen.

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`

Viser TextBox-inndata som standard for nyopprettede arbeidsområder, terminalfaner og terminalsplitt.

Type

`boolean`

Default

`false`

`terminal.focusTextBoxOnNewTerminals`

Fokuserer TextBox-inndata som standard for nyopprettede arbeidsområder, terminalfaner og terminalsplitt. Fokus viser også 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`

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

`notifications.soundWhenFocused`

Spill av varsellyden selv når ruten som varslet allerede har fokus. Av som standard, så en rute med fokus viser bare ringen og blinket.

Type

`boolean`

Default

`false`

`notifications.suppressOnlyFocusedSurface`

Når dette er på, trekkes et varselbanner bare automatisk tilbake når overflaten er nøyaktig den fokuserte overflaten. Et banner levert for en ikke-fokusert overflate i det for øyeblikket synlige workspace blir værende til du fokuserer den overflaten (eller klikker/avviser det), i stedet for å bli trukket tilbake når workspace blir synlig. Av beholder den gamle tilbaketrekkingen basert på workspace-synlighet.

Type

`boolean`

Default

`false`

`notifications.suppressWhenAppFocused`

Når dette er slått på, hopper cmux over skrivebordsbanneret for alle varsler mens cmux er den aktive appen, ikke bare for det fokuserte panelet. Varsler vises fortsatt i sidefeltet, lyden og den egendefinerte kommandoen kjøres fortsatt, og videresending til telefonen er uendret. Av fortsetter å vise bannere for andre workspaces og paneler mens cmux er i fokus.

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`

Varsle når en agent har vært inaktiv og venter på inndata (omtrent 60 sekunder etter at en tur er avsluttet). Varslingen undertrykkes mens bakgrunnsarbeid fra forrige tur fortsatt pågår, slik at en kjørende bygging eller overvåker ikke utløser et falskt ventevarsel.

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`

`12.5`

`sidebar.hideAllDetails`

Hide all per-workspace detail rows.

Type

`boolean`

Default

`false`

`sidebar.wrapWorkspaceTitles`

Boolske nøkler: sidebarFocus, browserFocus, markdownFocus, filePreviewTextEditorFocus, simulatorFocus, terminalFocus, commandPaletteVisible, terminalFindVisible, terminalAlternateScreen, workspaceCanvasLayout. Typede nøkler støtter sammenligninger: strengen sidebarMode (files, find, sessions, feed eller dock) og heltallene paneCount og workspaceCount. Sammenligningsoperatorene er ==, !=, =~ (regulært uttrykk), <, <=, >, >= og \`in \[a, b\]\`; en ukjent eller fraværende nøkkel leses som false. De boolske literalene true og false godtas også; \`key == false\` tilsvarer \`!key\`. Handlingens snarvei utløses bare (og kolliderer bare med andre snarveier) når klausulen er sann. Eksempler: { "selectWorkspaceByNumber": "!sidebarFocus" } velger arbeidsområder med Ctrl+1–9 overalt unntatt når høyre sidelinje har fokus; { "selectSurfaceByNumber": "sidebarMode == 'find' && paneCount > 1" } begrenser en binding til Finn-sidelinjen når arbeidsområdet har flere paneler.

### `shortcuts.when`

Valgfrie kontekstpredikater per handling (VS Code-lignende when-klausuler), indeksert etter cmux-handlings-id. En binding utløses bare — og kolliderer bare med en annen binding på samme tastetrykk — når klausulen er sann. Utelat klausulen for å beholde handlingens innebygde kontekst. Klausulenes vokabular:

-   `sidebarFocus`, `browserFocus`, `markdownFocus`, `filePreviewTextEditorFocus`, `simulatorFocus`, `terminalFocus`, `commandPaletteVisible`, `terminalFindVisible`, `terminalAlternateScreen`, `workspaceCanvasLayout` — boolske nøkler. En ukjent eller fraværende nøkkel leses som false; literalene true og false godtas også.
-   `sidebarMode` (`files`, `find`, `sessions`, `feed`, `dock`), `paneCount`, `workspaceCount` — typede nøkler for sammenligninger: høyre sidelinjes aktive modus (streng) samt antall paneler og arbeidsområder (heltall).
-   `!`, `&&`, `||`, `(…)`, `==`, `!=`, `=~`, `<`, `<=`, `>`, `>=`, `in [a, b]` — boolske operatorer, typede sammenligninger, regex-treff og listemedlemskap. Sammenligninger binder tettere enn && og ||.

Dette gjør for eksempel at Ctrl+1–9 velger arbeidsområder overalt unntatt når høyre sidelinje har fokus (slik at Ctrl+1–5 er ledig for sidelinjens modusvelger), og begrenser overflatevalg til Finn-sidelinjen når arbeidsområdet har flere paneler:

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