From aa7f73bfc1bbbc527de06df97c4f4e1798beef8d Mon Sep 17 00:00:00 2001 From: Oksana Korotkova Date: Fri, 11 Sep 2026 13:20:02 +0100 Subject: [PATCH 01/16] feat(backend): implement backward-compatible generator progress notifications MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements enhanced multi-phase progress notifications for Yeoman generators while maintaining full backward compatibility with existing generators. **Changes:** 1. **Interface (`youi-events.ts`)**: - Added `doGeneratorProgress()` method for new progress system - Kept `doGeneratorInstall()` for backward compatibility (CRITICAL) - Changed `doGeneratorDone` return type from `void` to `Thenable` to support async "Finalising..." phase 2. **Core Logic (`yeomanui.ts`)**: - Checks generator's `options.showGeneratorProgress` flag - If `true`: Enhanced 3-phase progress (writing, install, end) - If `false` or absent: Classic "Installing dependencies..." toast - Ensures zero breaking changes for existing generators 3. **VS Code Implementation (`vscode-youi-events.ts`)**: - `doGeneratorInstall()`: Shows classic toast (preserved) - `doGeneratorProgress()`: Shows enhanced progress with: * Project name in title: "Generating {projectName}" * Three phases: "Creating project files...", "Installing dependencies...", "Finalising..." * Minimum phase durations for visibility (2s, 0s, 1s) * Respects VS Code setting `ApplicationWizard.showGeneratorProgress` - `doGeneratorDone()`: Now async to show "Finalising..." before closing 4. **Messages (`messages.ts`)**: - Added localized progress messages following existing patterns: * `progress_preparing`, `progress_writing_files` * `progress_installing`, `progress_finalising` 5. **Test Fixes (`vscode-youi-events.spec.ts`)**: - Added `void` operator to async `doGeneratorDone()` calls - Fixes lint errors after return type change 6. **WebSocket Support (`server-youi-events.ts`)**: - Implemented `doGeneratorProgress()` for WebSocket clients - Changed `doGeneratorDone()` return type to `Promise` **Backward Compatibility:** - Generators without `showGeneratorProgress` option: ✅ Classic toast - Generators with `showGeneratorProgress: false`: ✅ Classic toast - Generators with `showGeneratorProgress: true`: ✨ Enhanced progress **Related:** This addresses the revert of PR #576 which broke backward compatibility. --- .../packages/backend/src/messages.ts | 4 + .../backend/src/vscode-youi-events.ts | 168 +++++++++++++++--- .../src/webSocketServer/server-youi-events.ts | 19 +- .../packages/backend/src/yeomanui.ts | 56 +++++- .../packages/backend/src/youi-adapter.ts | 2 +- .../packages/backend/src/youi-events.ts | 7 +- .../backend/test/vscode-youi-events.spec.ts | 6 +- 7 files changed, 229 insertions(+), 33 deletions(-) diff --git a/projects/yeoman-ui/packages/backend/src/messages.ts b/projects/yeoman-ui/packages/backend/src/messages.ts index cf90a5576..2975ba05a 100644 --- a/projects/yeoman-ui/packages/backend/src/messages.ts +++ b/projects/yeoman-ui/packages/backend/src/messages.ts @@ -30,6 +30,10 @@ export default { `The '${artifactName}' project has been generated.`, show_progress_button: "Open Output View", show_progress_message: "Generating...", + progress_preparing: "Preparing...", + progress_writing_files: "Creating project files...", + progress_installing: "Installing dependencies...", + progress_finalising: "Finalising...", add_to_workspace: "Open the project in a multi-root workspace", open_in_a_new_workspace: "Open the project in a stand-alone", create_and_close: "Create the project and close it for future use", diff --git a/projects/yeoman-ui/packages/backend/src/vscode-youi-events.ts b/projects/yeoman-ui/packages/backend/src/vscode-youi-events.ts index 9a0c4bff9..1905884d1 100644 --- a/projects/yeoman-ui/packages/backend/src/vscode-youi-events.ts +++ b/projects/yeoman-ui/packages/backend/src/vscode-youi-events.ts @@ -60,7 +60,13 @@ export class VSCodeYouiEvents implements YouiEvents { private readonly rpc: IRpc;

WebSocket legacy install fallback - Added fallback to doGeneratorInstall() when showProgress=false and phase=install - Preserves backward compatibility for non-opted-in WebSocket generators 2. Frontend generatorProgress RPC handler - Added generatorProgress(projectName, phase) method to App.vue - Registered in initRpc() functions list - Handles multi-phase progress updates in WebSocket mode 3. False "manual close" telemetry - Set GENERATOR_COMPLETED=true before doClose() in enhanced progress mode - Prevents AbstractWebviewPanel from treating webview disposal as manual close 4. Race condition in delayed phase transitions - Added pendingPhaseTimer to track and cancel pending setTimeout callbacks - Clear timer before scheduling new phase transitions - Clear timer in doGeneratorDone() and showInstallMessage() cleanup - Prevents out-of-order phase messages (e.g., "Finalising" -> "Installing" -> "Finalising") All changes maintain backward compatibility - generators without showGeneratorProgress option continue to show classic "Installing dependencies..." toast.

The setting gate allows consumers (app-modeler, app-generator) to let users opt out of enhanced progress notifications via VS Code settings. When ApplicationWizard.showGeneratorProgress is false: - Falls back to classic 'Installing dependencies...' toast on install phase - Does nothing on writing/end phases (backward compatible behavior) When the setting is true (default) AND generator opts in: - Shows enhanced multi-phase progress notifications Added tests: - Setting disabled + showProgress=true falls back to classic - Setting enabled + showProgress=true enters enhanced mode Tests: 328 passing --- .../backend/src/vscode-youi-events.ts | 17 +++++-- .../backend/test/vscode-youi-events.spec.ts | 47 +++++++++++++++++++ 2 files changed, 61 insertions(+), 3 deletions(-) diff --git a/projects/yeoman-ui/packages/backend/src/vscode-youi-events.ts b/projects/yeoman-ui/packages/backend/src/vscode-youi-events.ts index ca3198152..0704e357a 100644 --- a/projects/yeoman-ui/packages/backend/src/vscode-youi-events.ts +++ b/projects/yeoman-ui/packages/backend/src/vscode-youi-events.ts @@ -143,9 +143,20 @@ export class VSCodeYouiEvents implements YouiEvents { phase: "writing" | "install" | "end", showProgress: boolean = false ): void { - // Backward compatibility: if generator doesn't opt in, fall back to classic behavior - // (only show toast on "install" phase) - if (!showProgress) { + // Check VS Code setting (default: true) + // Note: This setting is not declared in yeoman-ui's package.json - consumers + // (e.g., application-modeler, app-generator) declare it in their package.json + // if they want users to control it.
