Command UI

One Effect handler. Palette plus any extra surface (context menu, CodeLens, tree item, title). Success/progress through NotificationModeService.

• Registration: services-extension-consumption (registerCommandWithRuntime)
• Confirmations / errors / modals: vscode-window-messages. Exception: a non-modal error toast with action buttons → NotificationModeService.showErrorWithActions
• Mode API: notification-mode-api.md

Recipe

1. Manifest + i18n

Two catalogs. Same key, different files.

• contributes.commands: "command": "sf.my.command", "title": "%deploy_this_source_text%" — %key% only (package-json-i18n-descriptions)
• package.nls.json: "deploy_this_source_text": "SFDX: Deploy This Source to Org" — Title Case, SFDX: prefix (i18n-messages)
• Same English string in i18n.ts under the same key
• Menu when for each surface (commandPalette, editor/context, explorer/context)
• commandLevelNotifications property key = that English title
• Runtime copy only in i18n.ts (vscode-window-messages)

COMMAND is messages.deploy_this_source_text (always English). nls.localize('deploy_this_source_text') is user-visible (locale-aware).

package.nls.ja.json / i18n.ja.ts are Partial — add a translation when you have one; English is the fallback.

Done: %key% in package.json + package.nls.json + i18n.ts; slot key equals messages.<title_key>; command in palette.

2. Register

Once: api.services.registerCommandWithRuntime(getRuntime()).

Palette when gates enablement (sf:project_opened, sf:has_target_org). when: never for internals (conflict helpers, status-bar click-to-toast).

Two command IDs only when VS Code arg shapes differ. Share one English title → one notification slot. Both stay in the palette.

Done: registerCommandWithRuntime for every contributed command ID.

3. Extra surfaces

Same command ID. Handler accepts optional args from the surface; palette path falls back (active editor / prompt).

export const myCommand = Effect.fn('myCommand')(function* (sourceUri?: URI, uris: URI[] = []) {
  const targets = sourceUri
    ? new Set([sourceUri, ...uris])
    : new Set([yield* api.services.EditorService.getActiveEditorUri()]);
});

new CodeLens(range, { command: 'sf.my.command', title, arguments: [uri] });

Done: every CodeLens / menu / TreeItem.command uses that ID.

4. Layer + slot

Merge NotificationModeService.Default(extensionSection, statusBarId, statusBarName) into AllServicesLayer. Copy an existing Default(...) in that package's extensionProvider.ts. Dispose the ManagedRuntime on deactivation.

Lookup: command → extensionLevelNotifications → global salesforcedx-vscode-services.notifications.

Add commandLevelNotifications property (English title key from step 1). Copy enum + enumDescriptions from a sibling slot; pick PAS / SO / PO — notification-mode-api.md. Slot description is a %key% in package.nls.json. Add extensionLevelNotifications if missing. Slot, not a boolean showSuccessNotification.

Type keys from package.json in src/utils/notificationMode.ts:

import type pkg from '../../package.json';

type CommandNotificationKey =
  keyof (typeof pkg)['contributes']['configuration']['properties']['salesforcedx-vscode-metadata.commandLevelNotifications']['properties'];

export type ProgressOnlyCommandKey = 'SFDX: Diff Source Against Org';
export type ProgressAndSuccessCommandKey = Exclude<CommandNotificationKey, ProgressOnlyCommandKey>;

ESLint notificationSlotMatchesPackageJson checks SuccessOnly / ProgressOnly aliases against the slot enum.

Done: Default(...) in the layer; slot exists; COMMAND typed.

5. Progress + success

const COMMAND: ProgressAndSuccessCommandKey = messages.deploy_this_source_text;
const notificationMode = yield* api.services.NotificationModeService;
const location = yield* notificationMode.getProgressLocation(COMMAND);

yield* work.pipe(
  promptService.withProgress(nls.localize('working'), location),
  Effect.tap(() =>
    notificationMode.showSuccessNotification(
      COMMAND,
      nls.localize('command_succeeded_text', nls.localize('deploy_this_source_text'))
    )
  )
);

Cancellable: promptService.withCancellableProgress(title, location).

forceShow: true when the message must not be suppressed (request ID).

Helpers that wrap vscode.window.withProgress (e.g. metadata withPreparationProgress) take the command key and call getProgressLocation.

Done: getProgressLocation + showSuccessNotification.
