dsh-file-menu

Right-click menus for the DeepSeek Harness (DSH) Web UI.

The DSH Web client ships no contextmenu handler, so right-clicking inside the app does nothing useful — no copy, no paste, no "open file location". This plugin adds a Codex-style menu that fits whatever you clicked.

Features

The menu is built from the element under the cursor:

Right-click target	Menu rows
Selected text	Copy
A paragraph (no selection)	Copy this paragraph
Input box / editable area	Cut · Copy · Paste · Select all
A file reference (delivered-file card, produced-file chip, inline file mention)	Copy path · Reveal in file manager · Open with default app
A link	Copy link address · Open in browser
Alt + right-click	Diagnostics: copy element info

• Copy goes through the host route /file-menu/clipboard (Electron main-process clipboard, falling back to PowerShell Set-Clipboard) instead of relying on the renderer's clipboard permission. If the host route is unavailable, the client falls back to document.execCommand('copy').
• Reveal in file manager selects the file where the OS supports it — Windows Explorer /select, macOS Finder open -R. On Linux xdg-open has no "select" concept, so the containing directory is opened instead. If the host route is missing entirely, the client falls back to DSH's own /open-in-app/open.
• File paths are read from the element's title, data-path, data-file-path, dataset.*path, the element's own text (DSH's tool-row file links carry no attribute at all — the path is only in the text), or a selected absolute path. DSH renders in-workspace references relative to the session workspace (dsh-plugins/x/README.md, @docs/plan.md), so relative candidates are resolved against the current session's workspace root, which the client half reads from DSH's sessions service (list.getSnapshot() → byId[current].cwd). ~/... is expanded by the host half. When no root is available the file rows are simply not shown rather than guessed.

Install

From npm:

dsh plugin --profile web add @z1995418/dsh-file-menu

From source:

dsh plugin --profile web add github:dreammaker2016/dsh-file-menu

Every release also carries a prebuilt tarball (dsh-file-menu.tgz), installable with dsh plugin --profile web add <tarball-url>.

Use the profile you actually run (web for the Web client, your own profile name for DSH Desktop). Restart DSH after installing.

Uninstall

dsh plugin --profile web remove dsh-file-menu

Limits

• A relative path that appears inside running prose is recognized only when it is a single token (no whitespace), contains a path separator, and its last segment carries a file extension. Paths with spaces, bare basenames, and extension-less directories are skipped — that is what keeps ordinary sentences ("copy/paste this") from growing file actions.
• Relative candidates need the session workspace root. If DSH's sessions service is unavailable, the file rows are hidden instead of guessed.
• The two halves version independently: the client (lib/client.js) is versioned with the package, while the host half reports its own version from GET /file-menu/status.

How it works

• Host half lib/index.js — a webServer prefix route /file-menu serving ping, status, hello, menu, diag, clipboard, reveal and open. reveal/open take { path, base }, resolve absolute paths directly, ~/... against the home directory and relative paths against base (the session workspace root), then act only on paths that exist.
• Client half lib/client.js — a capture-phase contextmenu handler plus a plain-DOM menu (no React dependency), with pointerdown + elementFromPoint activation so an upstream stopPropagation cannot swallow the click.
• cordis.patch.yml — the single bundle row that registers the host half. The client bundle is served automatically because the host entry declares dsh.client.
