Codewise VS Code extension

This extension enables C# definition, references, and hover from a prebuilt SCIP index in desktop VS Code, vscode.dev, and github.dev. Desktop VS Code launches the bundled language server over stdio. VS Code for the Web runs the same shared server in a Web Worker.

Set codewise.indexPath to an absolute desktop path or a workspace URI, or place the index at .scip/index.scip in the opened workspace. Use Codewise: Select Index File and Codewise: Restart Language Server from the Command Palette.

When the setting is empty and the root workspace is a dotnet/roslyn checkout, the extension looks up roslyn-scip-<HEAD> in the jjonescz/indexer GitHub Actions artifacts. It tries anonymous access first, then asks for GitHub repo authentication only when private or rate-limited access requires it. The extension verifies the bundle's commit, byte size, and SHA-256 from its manifest and caches the index by commit in extension global storage.

Desktop VS Code obtains the Roslyn commit from local Git. On vscode.dev and github.dev, the extension obtains the exact revision from the built-in Remote Repositories metadata API. If that metadata is unavailable, it falls back to a previously entered SHA or asks for the full SHA and remembers it in workspace state. You can override automatic detection with codewise.roslynCommit.

When a virtual web workspace inherits a desktop file path in codewise.indexPath, the extension ignores that unavailable path and continues with the workspace index and hosted-artifact fallbacks.

Authentication and artifact diagnostics are written to Output: Codewise without access tokens or account identifiers. If GitHub sign-in fails, also inspect Output: GitHub Authentication for the built-in provider's per-flow diagnostics.
