dsh-open-folder-visible

Windows fix for DSH: makes the Session-header "open workspace in File Explorer" action raise a visible window.

The problem

The Session header has an "Open In…" split button whose default action opens the session's workspace directory in File Explorer (also bound to Ctrl+Alt+O).

On Windows, clicking it starts Explorer, creates the correct directory window — and that window is invisible. The button settles back to idle and reports nothing, so the click looks like it did nothing at all.

Why

The shipped explorer catalog entry in @deepseek-ai/dsh-host-open-in-app is kind: 'shell-open', which on Windows ends at @deepseek-ai/dsh-native-command:

execFile('explorer.exe', ['<file:// URI>'], { encoding: 'utf8', signal, windowsHide: true })

windowsHide: true exists to suppress the transient console window a CLI child would flash. Applied to Explorer it means the window is created with IsWindowVisible() false.

Upstream judges the launch by exit code alone, and Explorer's exit 1 counts as a delegated handoff (runExplorer), so the route answers { ok: true } whether or not a window ever became visible.

Measured

Same host, same call shape, only the flag differs:

The fix

The Host half adds one route, POST /open-folder-visible/open, that spawns the same explorer.exe with windowsHide: false. Everything else mirrors the shipped opener: an argv array (never a shell string), Explorer's exit 1 accepted as a delegated handoff, and a watch window so a launcher still running is counted as launched rather than killed.

The browser half wraps globalThis.fetch and reroutes only the file-manager launch to that route. Everything else — every other application, every other request on the page — is passed through untouched.

What this deliberately does not do

It does not replace the split button. The shipped button, its application menu, its icons, its per-gesture feedback and the Ctrl+Alt+O shortcut (workspace.openLocal) all stay exactly as they are. Replacing the component would mean re-registering that shortcut, and forgetting to is how a "fix" ends up removing the hotkey.

Installing any plugin runs third-party code with your own permissions. Pin a commit if you want a fixed revision: github:King20260919/dsh-open-folder-visible#<sha>.

Restart DSH after installing: the Host half registers a route at load time.

Configuration

Known limitations

• Windows only. On other platforms the route answers 501; nothing else changes.
• This fixes the workspace-open action only. The file-location action ("reveal in File Explorer", explorer.exe /select,<file>, used by the delivered-file cards and the changed-files review) is affected by the same windowsHide flag through a different code path (@deepseek-ai/dsh-api-session-controller → revealNativePath), and is not covered here.
• It reroutes one request by wrapping globalThis.fetch. If a future release changes the shipped launch route or the request body shape, the reroute simply stops matching and the shipped behaviour returns — the wrapper never breaks the original request.
