Settings

This is a guide, not the contract. What the platform guarantees is specified under openspec/specs/. For this page: ui-primitives · host-services. Where this page and a specification disagree, the specification is right, and that is a defect in this page: change the behaviour there, then explain it here.

The host settings surface is a registry: the shell registers its own sections, plugins contribute through ctx, and a distribution can do both: add sections and hide any of them.

Do it

// src/app/… — inside an injection context (a component, or provideEnvironmentInitializer)
const settings = inject(SettingsService);


const handle = settings.register({
  id: 'acme.workspace',
  title: 'acme.workspace.title',
  group: 'settings.group.options',
  order: 20,
  rows: [
    { id: 'acme.autosave', label: 'acme.autosave.label', control: {
        kind: 'toggle', value: () => prefs.autosave(), set: (v) => prefs.setAutosave(v),
    } },
  ],
});


settings.open('acme.workspace');   // open the dialog on a specific section
handle.dispose();                  // remove the section again

Read it

settings.all();          // the sections the dialog draws, ordered, with omitted sections and rows dropped
settings.registered();   // everything contributed, including what omit hides

all() is ordered by order, then registration order. registered() is what a dev-mode report needs to tell an omit that hid a row from one that hit nothing.

What asks about unsaved work

Nothing on this page asks; registering, opening and disposing a section closes no surface.

Switched off

No switch governs the settings surface. To remove built-in settings, prefer provideShell({ omit: ['setting:…'] }), which is declarative and lasting.

In depth

The same rules as a weaver. Control kinds and the “each control owns its own storage” rule are the same ones a weaver uses; see authoring a weaver. Registering an existing id replaces that section in place.

The ids you can omit. Curating the settings surface lists them.
