Module WorkspaceProvider 

WorkspaceProvider (Environment)

RESPONSIBILITIES:

• Implements WorkspaceProvider and WorkspaceEditApplier traits for MountainEnvironment
• Manages multi-root workspace folder operations and configuration
• Provides workspace trust management and file discovery capabilities
• Handles workspace edit application and custom editor routing

ARCHITECTURAL ROLE:

• Core provider in the Environment system, exposing workspace-level functionality to frontend via gRPC through the AirService
• Workspace provider is one of the foundational services alongside Document, Configuration, and Diagnostic providers
• Integrates with ApplicationState for persistent workspace folder storage

ERROR HANDLING:

• Uses CommonError for all operations
• Application state lock errors are mapped using Utility::MapApplicationStateLockErrorToCommonError
• Some operations are stubbed with logging (FindFilesInWorkspace, OpenFile, ApplyWorkspaceEdit)

PERFORMANCE:

• Workspace folder lookup uses O(n) linear search through folder list
• Lock contention on ApplicationState.Workspace.WorkspaceFolders should be minimized
• File discovery and workspace edit application are not yet optimized

VS CODE REFERENCE:

• vs/workbench/services/workspace/browser/workspaceService.ts - workspace service implementation
• vs/workbench/contrib/files/common/editors/textFileEditor.ts - file editor integration
• vs/platform/workspace/common/workspace.ts - workspace types and interfaces

TODO:

• Implement actual file search with glob pattern matching
• Implement file opening with workspace-relative paths
• Complete workspace edit application logic
• Add workspace event propagation to subscribers
• Implement custom editor routing by view type

MODULE CONTENTS:

• WorkspaceProvider implementation:
• GetWorkspaceFoldersInfo - enumerate all workspace folders
• GetWorkspaceFolderInfo - find folder containing a URI
• GetWorkspaceName - workspace identifier from state
• GetWorkspaceConfigurationPath - .code-workspace path
• IsWorkspaceTrusted - trust status check
• RequestWorkspaceTrust - trust acquisition (stub)
• FindFilesInWorkspace - file discovery (stub)
• OpenFile - file opening (stub)
• WorkspaceEditApplier implementation:
• ApplyWorkspaceEdit - edit application (stub)
• Data types: [(Url, String, usize)] tuple for folder info (URI, name, index)
