dsh-settings-search-plugin

English | 中文

A browser-only plugin that adds a search field to the DSH Web Settings panel. Typing shows an independent candidate list over the content column; clicking a candidate navigates to the owning section and, for item-level rows, focuses and highlights the setting. Registration is optional — sections are indexed from the slot ledger and from their rendered DOM, so third-party settings pages are searchable without any plugin changes.

How the index is built

Searchable rows come from three sources, in priority order:

1. Slot ledger (declarative, always complete) — every settings.section registration is a tab-level candidate, whether its plugin registers search metadata or not and whether the user ever visited the section. The ledger is read through the injected slots service, so any plugin that contributes a settings page appears in search immediately.
2. Registration surface (optional enhancement) — a settings plugin may call window.__DSH_SETTINGS_SEARCH__.register(sectionId, spec) with item-level rows, rich keywords, and data-settings-item anchors for precise jump-and-focus. Registration is an opt-in; sections that skip it still get tab-level search from the ledger.
3. Rendered-DOM scan (visited sections) — the section observer scans the active section's DOM (label > strong + small, [class*="title"]/[class*="heading"] groups, headings, and short leaf text) and caches item-level candidates per section. This covers non-registering plugins once the user opens their page; until then only the tab name is searchable.

Candidate rows render as buttons carrying the setting name, an optional description, and a badge with the owning section's label. Clicking an item navigates to its section, scrolls the setting into view, and flashes an outline around it; anchored (registered) rows resolve by data-settings-item, scanned rows fall back to matching the setting title text.

What it reads and writes

The plugin reads the slots service for the ledger and observes the settings dialog DOM. It writes nothing on the wire: search state, the registry surface, and the candidate overlay are all page-local. The registration surface is a plain object on globalThis (__DSH_SETTINGS_SEARCH__) so settings plugins may register before this plugin's bundle mounts; whichever loads first creates the holder, and register always writes the shared map.

The dialog and section containers are located by structure (nav, nav's next sibling, its last child), not by class — the DSH client uses CSS Modules with hashed names, so class selectors are unreliable. The nav label is read from the button's longest span text to exclude SVG path data.

Registration reference

// In a settings plugin's client apply():
window.__DSH_SETTINGS_SEARCH__?.register('local-shell-tools', {
  label: 'Shell',
  keywords: 'shell 终端 命令 cmd bash powershell pwsh 语言环境',
  items: [
    { id: 'bashLang', label: '语言环境', desc: '写入 LANG 与 LC_ALL', keywords: '语言 locale lang 环境' },
  ],
})

The registry holder is created lazily by either side, so the optional chain is safe even when this plugin is absent or loads later. items[].id should match a data-settings-item attribute on the rendered setting's container for anchored focus.

Model Experience

None, as a presentation-only plugin: search candidates and navigation are browser UI and never reach a model request. The plugin contributes no system-prompt prose and no tool schemas.

KV Cache effect

No invalidation. The plugin runs entirely in the browser and changes no model request shape, so it never affects an established prefix.

Known Limitations and Deferred Work

• Item-level search for never-visited, non-registering sections — the ledger supplies tab-level rows for every section, but item-level candidates come from the registration surface or the rendered DOM. A section the user has never opened and whose plugin never registers exposes only its tab name; full item coverage for such sections would require reading each plugin's locale dictionaries or a searchItems channel in slots.register, both deferred.
• Candidate text is normalized, not stemmed — matching is case- and whitespace-normalized substring inclusion; pinyin and fuzzy recall are not implemented.
• Overlay is a page-local absolute-positioned layer — it tracks the settings panel's header and nav widths at install time; a theme that changes those dimensions after the dialog mounts needs a panel re-open to re-measure.

Installation

Copy the block below to your DSH agent and it will finish the install:

Install the settings-search plugin (@doiiarx/dsh-settings-search-plugin):

1. Clone the repo:
   git clone https://github.com/DoiiarX/dsh-settings-search-plugin
   cd dsh-settings-search-plugin
2. Install dependencies: pnpm install
   (the built lib/ output is already committed; peer deps @deepseek-ai/cordis
   and @deepseek-ai/dsh-client-ui-slots come from the harness runtime.)
3. Mount into the web profile: edit $HOME/.dsh/profiles/web/package.json,
   add "@doiiarx/dsh-settings-search-plugin": "link:<absolute-path-to-this-dir>"
   under dependencies, and "@doiiarx/dsh-settings-search-plugin" under
   dsh.profile.bundles.
4. Run pnpm install in the profile directory.
5. Restart the web process and verify the Settings panel shows a search field.

This plugin is browser-only (no settings namespace, no model tools), so it needs no WEB_SETTINGS_NAMESPACES entry and no host rebuild.
