dsh-chat-wallpaper

One picture behind the DeepSeek Harness chat UI — and the surfaces in front of it rebuilt as glass, so the picture shows through instead of being covered.

中文

What it does

• Wallpaper layer. A fixed image layer sits behind the whole shell; the app's background tokens are repointed at translucent tints so the frame, sidebar and content column all let the picture through.
• Glass surfaces. The composer card, the user's own message bubbles and the new-chat button get a frosted treatment (blur + tint + a 1px inner ring), so they read as material in front of the wallpaper rather than flat boxes.
• Blur follows the conversation. An empty new conversation shows the wallpaper at exactly the slider's blur. As soon as the composer has text — or the conversation already has messages — 5px is added on top, with a 0.45s transition, and it stays after the message is sent.
• Settings-style windows frost the backdrop. When a stacked window opens (settings, plugin market, pairing dialog…), the background is frosted instantly and the window in front keeps its own crisp pixels; closing it restores the sharp picture immediately. In-composer popups such as the / command palette are not treated as windows and never freeze the background.
• Your own picture. The panel's 选择图片… button stores any local image in IndexedDB (per browser profile, never uploaded). 默认 restores the bundled picture.
• Controls in the sidebar footer. A small button next to the sidebar's utility icons opens the sliders, so nothing is added to Settings.

Install

dsh plugin add dsh-chat-wallpaper

Not on npm yet — install the prebuilt tarball instead:

dsh plugin add https://github.com/yuxiangwhn/dsh-chat-wallpaper/releases/download/v1.1.1/dsh-chat-wallpaper-1.1.1.tgz

Or from the plugin market in DSH (Plugins → discover/search dsh-chat-wallpaper) once the entry is listed.

Controls

Control	Range	What it changes
亮度 / Brightness	50–220%	brightness filter on the wallpaper layer
透明度 / Opacity	15–100%	opacity of the wallpaper layer
磨砂 / Blur	0–24px	base blur of the wallpaper layer
面板 / Panel	15–98%	opacity of the shell tints (content, sidebar, panels)
图片 / Image	—	pick a local image, or restore the bundled default
重置 / Reset	—	back to the defaults

Settings are stored in localStorage under dsh-chat-wallpaper:settings:v1; a picked image lives in IndexedDB (dsh-chat-wallpaper).

Compatibility

Developed and verified on the DSH desktop window (Windows, DSH 0.2.2-rc.1). The browser (Web) surface is supported by the same code paths; macOS uses the darwin frame rules the shell publishes.

Privacy

The plugin makes no network requests and has no host-side code or storage. The bundled default picture is generated by scripts/make-wallpaper.py; an image you pick stays in this browser profile's IndexedDB.

Known limits

• The glass treatment targets the shell's current DOM: the composer card, the user-bubble rows and the sidebar footer. A large host update that renames those components can leave parts of the UI untreated until the selectors are updated.
• The wallpaper is one fixed layer: very wide or multi-monitor setups show it scaled to cover the window, not tiled per screen.
• Blur and transparency are CSS effects on the page; they do not affect the window's own drop shadow or the OS title bar.

Development

python build_client.py                 # client.src.js -> lib/client.js, embeds assets/wall.jpg
python scripts/make-wallpaper.py       # regenerate the bundled default picture

client.src.js is the readable source; lib/client.js is what DSH loads and contains the image as a data URL (the desktop shell answers file-looking dsh-app:// paths itself, so the picture cannot be fetched as a URL).

License

MIT. The bundled wallpaper is generated procedurally by the script above and carries the same license.
