Add "Close All Other Windows" command to VS Code

[Copilot]

Summary

Implements a new command workbench.action.closeAllOtherWindows that allows users to close all open windows except the currently active one. This addresses a common workflow need for users working with multiple VS Code windows.

Changes

New Command Implementation

• Command ID: workbench.action.closeAllOtherWindows
• Title: "Close All Other Windows" with mnemonic support
• Accessibility: Available via Command Palette (F1)
• Menu Integration: Added to File menu in the "Close" section (order 5)

Technical Implementation

• Added CloseAllOtherWindowsAction class in src/vs/workbench/electron-browser/actions/windowActions.ts
• Follows existing VS Code patterns (similar structure to CloseWindowAction)
• Uses INativeHostService for window management:
  • getWindows({ includeAuxiliaryWindows: true }) to retrieve all windows
  • getActiveWindow().vscodeWindowId to identify current window
  • closeWindow({ targetWindowId }) to close each non-current window
• Handles auxiliary windows correctly
• Uses Promise.allSettled() for robust concurrent window closing

Registration

• Imported and registered action in src/vs/workbench/electron-browser/desktop.contribution.ts
• Follows existing action registration patterns

Testing

• Added comprehensive test suite in src/vs/workbench/electron-browser/actions/test/windowActions.test.ts
• Tests cover:
  • Main functionality (closing multiple windows except current)
  • Edge case with single window (no action needed)
  • Auxiliary window handling
• Uses mock INativeHostService for isolated testing

Usage

Users can now:

1. Access via Command Palette: Ctrl+Shift+P → "Close All Other Windows"
2. Access via File menu: File → Close All Other Windows
3. Quickly close multiple VS Code windows while keeping their current workspace active

Scope

This feature is specific to the Electron (desktop) environment where multiple native windows are supported. The browser version already handles window management through existing host service patterns.

Code Quality

• Minimal Changes: Only 3 files modified (211 lines added, 1 line modified, 0 deletions)
• Type Safety: Full TypeScript implementation with proper interfaces
• Localization: Proper localize2() usage for internationalization
• Error Handling: Robust async patterns with proper error handling
• Performance: Concurrent window operations for better user experience
• Accessibility: Mnemonic keyboard navigation support

The implementation follows all VS Code coding guidelines including tab indentation, localization patterns, and architectural conventions.

Fixed test mocking issues that were likely causing CI failures. Updated the test to use proper sinon-based mocking instead of globalThis manipulation, and improved import patterns to match VS Code conventions. Commit: 451af70
