dsh-premium-themes

English | 中文

A standalone, hot-pluggable premium palette plugin for the dsh Web surface — no core changes, everything rides public extension points. It adds a 配色 (Palette) row below the Appearance row in General settings with eight curated schemes (Tokyo Night, Nord, Catppuccin Mocha, Everforest, Rosé Pine, Ayu Mirage, Catppuccin Latte, Paper Gold) and a 导入配色 (Import palette) dialog for custom palettes.

Every palette — built-in or imported — is a third-party theme definition with a full alias-token map: switching repaints backgrounds, borders, brand, buttons, text, code surfaces, the sidebar, and scrollbars. Selections persist across reloads and browser sessions; the 默认 (Default) chip restores the light/dark/system preference that was active before the palette was chosen.

Screenshots

The Palette row in settings — eight built-in chips, the imported 墨玉翡翠 chip and the 导入配色 import button:

Paper Gold — 羊皮纸金 (light)	Tokyo Night — 东京夜 (dark)

墨玉翡翠 — imported custom palette (dark)	Default light (base)

Custom palette import

Give a name, a scheme (light/dark), a background and an accent color; the plugin deterministically derives the full token map (src/derive.ts) — layered surfaces, borders, buttons, text steps, code blocks, sidebar, scrollbars. An optional advanced JSON field accepts text/surface seed colors and explicit --dsw-* token overrides:

{ "text": "#f2e9dc", "surface": "#20203a", "tokens": { "--dsw-alias-brand-primary": "#ffcc66" } }

Imported palettes persist in the plugin's own settings namespace (machine ids derive from the name; non-latin names get a generated id), appear as chips next to the built-ins, and can be deleted from the dialog (removing the active one restores the base preference).

Install (hot-plug)

# From this repository (pnpm builds via the prepare script):
dsh plugin web add github:xiaoyanzi191/dsh-premium-themes

# Append one row to the profile patch layer — $DSH_HOME/profiles/web/cordis.patch.yml:
#
#   - insert:
#       - id: ui-premium-themes
#         name: '@deepseek-ai/dsh-client-ui-premium-themes'

Saving the patch hot-reloads the composition; refresh the page once and the Palette row appears in 设置 → 通用设置 below 外观. To turn the feature off, remove the row (or add disabled: true) — the next refresh drops the row and any active palette falls back to the base preference.

Note: row-level inject entries are service names, not plugin ids; the browser-side load order comes from the package's own dsh.client.inject graph edges, and the node half depends only on the optional settings/webServer services.

Development

pnpm install
pnpm run build   # tsc -> lib/types, then tsdown -> lib/index.js + lib/client.js
pnpm test        # vitest: settings, derivation, host routes (35 specs)

The two client-wiring/UI suites (apply.client.spec.ts, palette-row.client.spec.tsx) import the dsh client bundles, which npm ships as browser closure factories — they run inside a deepseek-harness checkout (pnpm run test:client there), where vitest resolves the package sources. Clone into packages/client/ of a deepseek-harness checkout to develop inside the monorepo (the package's workspace setup there uses workspace:* dependencies and the upstream clientBundle preset; this repository's tsdown.config.ts is a self-contained snapshot of that preset).

Compatibility

Built against the dsh packages published under the npm next tag (^0.1.0-rc.6). The plugin requires the ui-theme plugin in the composition (it registers themes through its public runtime).
