dsh-web-tray

dsh-web-tray

中文 | English

A Windows Start menu entry and a minimal tray icon for dsh web running inside WSL, with exactly two entries — 打开 DeepSeek Harness and 退出 DeepSeek Harness — and nothing else. No watchdog, no idle stop, no status file, and no DSH plugin: DSH never loads this package, and this package does not care how DSH was installed. It needs a dsh command and a WSL instance to run it in.

Fork of liyu34/dsh-wsl-tray (upstream ff03276, v0.1.7, MIT). The upstream architecture — desktop shortcut, hidden tray helper — is kept; the watchdog, the menu switches and the status monitoring are gone.

What it does

• Pick DeepSeek Harness (Web) from the Start menu. The tray starts hidden. If nothing answers on the configured URL, start.sh starts the instance (hidden, never awaited) and the page is opened once with that run's ?token= URL. A window that already shows the page is reused, and if the instance behind it was down, that window is reloaded instead of a second copy being opened somewhere else.
• Tray icon, started through wscript.exe + JScript so no console window ever appears:
  • left click: show DSH
  • right click: 打开 DeepSeek Harness / separator / 退出 DeepSeek Harness
  • 退出 asks stop.sh to stop the instance, closes every window showing the page (Ctrl+W: the tab in a browser window, the window in an app window — other tabs are never touched), and the tray exits.
  • Closing a window by hand does nothing to DSH and nothing to the tray.
• The menu is drawn to match the desktop app's own tray menu. That menu is Chromium's, not the Windows CreatePopupMenu look, so the colours and metrics were measured off both tray icons on the same screen and are reproduced here: dark #1F1F1F panel 175×97 px, #E3E3E3 labels, #363636 hover, a full-width #5E5E5E separator, the system UI font at 9pt, and DPI-aware scaling. Corners are Windows 11's own rounding. The constants live in windows/dsh-web-tray.ps1 and tests/tray.spec.ts asserts them through Windows interop.
• The tray icon is the page's own favicon whale in the two inks the notification area can need (black on a light taskbar, white on a dark one), at the size the desktop app's tray icon uses; the shortcut wears the same favicon, the mark alone on transparency, which is what a Chromium "install as app" shortcut carries. The taskbar theme is re-read every five seconds.
• Any Chromium browser can host the page: Chrome, Edge, Brave, Vivaldi, Opera, Chromium, ungoogled-chromium, Thorium, Yandex and Arc all take --app=<url> and share the window class, so the page opens as an app window in the browser it was already seen in, or in the default browser when that one is Chromium-like. A non-Chromium default gets a plain tab.

Requirements

• Windows 10/11 with WSL2, and the Windows PowerShell 5.1 that ships with it. PowerShell 7 is neither needed nor used.
• Node.js ≥20 to install and to run the dsh-web-tray commands. The tray itself needs no Node: it is one hidden PowerShell process, and WSL runs two shell scripts on demand.
• A dsh command that starts the web UI. Anything that starts one works — see DSH_COMMAND below.

Install

npm i -g dsh-web-tray
dsh-web-tray install --distro Debian --workspace ~/work

Or without installing: npx dsh-web-tray install.

Installing writes one Windows directory and one Start menu shortcut:

Nothing is written into the WSL file system, and nothing is written into DSH's home directory beyond that one .dsh\dsh-web-tray directory.

Coming from 0.3.0 (the DSH plugin): install 1.0, then drop the plugin and its old directory — 1.0 keeps no compatibility with either.

dsh plugin --profile web remove dsh-web-tray
rm -rf ~/.dsh/dsh-web-tray

Commands

uninstall talks to the tray through a marker file (tray-exit.flag): the tray's five-second tick consumes it and exits, so the icon is gone before its files are. If the tray does not answer within ten seconds, one PowerShell call stops it.

Configuration

tray.env is the whole configuration, and both the tray and start.sh read it:

DISTRO='Debian'
WSL_DIR='/mnt/c/Users/me/.dsh/dsh-web-tray'
WEB_URL='http://127.0.0.1:3080'
WORKSPACE='/home/me/work'
DSH_COMMAND='dsh web --no-open'
SHORTCUT_NAME='DSH Web'

Values are single-quoted and taken verbatim, so a value containing a quote or a newline is rejected at install time rather than silently mangled. Edit the file and re-run dsh-web-tray status to check it; keep LF endings if you edit it on Windows.

Running DSH from a source checkout is just a different command line:

WORKSPACE='/home/me/harness'
DSH_COMMAND='pnpm --dir /home/me/harness run dsh:web'

start.sh execs that command in WORKSPACE with its output appended to start.log beside it. It refuses, loudly, when the workspace does not exist. A file at ~/.dsh/dsh-web-tray.env (KEY=VALUE per line) is sourced first, which is how a token for an MCP server gets to the launched DSH.

How it works

DSH Web.lnk
 └─ wscript.exe //E:JScript //B dsh-web-tray.js        GUI host: no console is allocated
     └─ powershell.exe -WindowStyle Hidden -File dsh-web-tray.ps1
         ├─ read tray.env → distro, /mnt path, URL, shortcut name
         ├─ build the styled menu, pick the tray ink, repair the Start menu entry
         ├─ start failing open: reuse a window already showing the page, otherwise start
         │  DSH through  wsl.exe -d <distro> -- bash -lc "exec '<dir>/start.sh'"
         │  and finish with a reload or an --app window when the URL answers
         └─ Application.Run(): left click / menu, and one five-second tick that owns the
            tray ink and the uninstall marker

The exit entry asks stop.sh to stop the instance and closes the windows showing the page; both calls are hidden and never awaited, because awaiting wsl.exe on the UI thread is what used to wedge the tray. The single-instance mutex is per install directory, so a second double-click of the same shortcut only shows DSH.

The only things it asks of DSH

1. Start with the configured command (dsh web --no-open by default).
2. Print the launch URL — http://<host>:<port>/?token=… — on stdout; the tray reads it from start.log to open an already-authorised page. If no token is known (an instance someone else started), the page is opened without one and may ask you to sign in.
3. stop.sh finds the instance by inspecting /proc/<pid>/cmdline for dsh web, so a stale PID file cannot kill an unrelated process. It stops every dsh web instance it finds.

Known limitations

• A WSL distribution whose name contains a space cannot be addressed: wsl.exe reads the raw command line, so no quoting survives.
• /mnt/<drive> has to be mounted at run time, because the two shell scripts live on the Windows side and are executed from there. A distro with automount = false can still show and reload an open window, but the tray cannot start DSH.
• The shell scripts and tray.env are used from bash, so they must keep LF endings. An editor that "fixes" them to CRLF breaks start.sh; dsh-web-tray status warns about it.
• start.log and tray.log grow without rotation.
• One install per Windows user; the shortcut's name comes from SHORTCUT_NAME.

Development

npm test                                  # 34 tests: installer rules, icon assets, tray interop
npm run typecheck
DSH_WEB_TRAY_REQUIRE_INTEROP=1 npm test   # fail instead of skip when Windows is unreachable

tests/tray.spec.ts runs the real helper with -SelfTest, which builds the actual NotifyIcon and ContextMenuStrip and prints the contract as JSON without showing any UI — that is where the measured palette, the menu metrics and the two keyboard chords are pinned. tests/installer.spec.ts covers the path, environment and file rules hermetically, and tests/icons.spec.ts parses the bundled .ico files and pins their frames and geometry.

Syncing with upstream

git remote -v                                 # upstream = liyu34/dsh-wsl-tray
git fetch upstream && git log --oneline upstream/master ^master
