dsh-workspace-browser

Standalone Cordis client plugin that gives the shipped dsh web client the workspace features it does not have: the sidebar Recents section, collapsible section headers, the project editor with extra source folders, pin/rename/fork/archive row actions, search, shortcuts, and the conversation-hero workspace picker.

Why it exists

The deployed client (0.2.0-rc.2, the 2026-09-29 Desktop build) ships a workspace browser with no Recents, no collapsible sections and no project editor. This plugin replaces that region with the feature-complete implementation from the harness's winexeNew branch.

cordis.patch.yml disables the in-tree ui-workspace row — both claim the same slots, locale namespace (workspace) and ctx.uiWorkspace service — and loads this plugin instead. A bundle whose slots never register therefore leaves the workspace region empty, which is why the client-half surface is checked against the host before any install (see Verification).

Source folders on a host without the folder API

addFolder / removeFolder / setPrimaryFolder and the folders projection on a workspace view exist only on the newer workspace controller; the shipped host has none of them. The plugin owns the first two there:

• the folder list lives in the plugin's own persisted viewing store (persist: 'dsh.workspace.view.v5') and is also written to .dsh/storages/workspace-browser-folders.json. A copied .dsh home carries that file; browser localStorage is outside .dsh and does not;
• the browser merges those folders into the Workspace list it derives from (mergePluginFolders in src/client/tree.ts) and attributes Sessions to a Workspace by matching their cwd against the list — the host leaves such Sessions ungrouped, so only unclaimed ones are borrowed;
• adding and removing folders works from the project editor exactly as it does on a newer host.

Set as primary is plugin-owned where the host lacks the API: the promoted directory is stored in the same viewing store, and the previous host path becomes an extra folder. Later New Session creates with that cwd alone (the shipped host accepts a create that sends cwd and no workspaceId), and the browser borrows the Session back by cwd. The host registry path itself does not change.

Where the host does expose the folder API (src/client/host-capabilities.d.ts declares the three methods optional), all three editor actions route to it instead.

The desktop window exposes the OS folder dialog (__DSH_DIRECTORY_PICKER__). When a LAN bind (0.0.0.0) has mounted the in-app "Select Workspace Directory" browser, the plugin still opens the OS dialog in that window. A remote browser has no bridge and keeps the composed in-app flow.

The tag appgen-0.3.0 keeps an earlier parity-only build (exactly the host's own feature set) for a host that lacks the newer client module table.

Install

dsh plugin --profile desktop add github:lihongxu0221/dsh-workspace-browser

The GUI plugin manager does the same. cordis.patch.yml is declared by dsh.bundle.patch, so it must stay in files: a packed package (git or npm install) that lacks it is rejected with failed to read overlay.

Build

pnpm install
pnpm run typecheck              # against the generation pinned in devDependencies
pnpm run build                  # tsc: src -> lib/types (the client preset consumes this)
node scripts/build-client.mjs   # harness client preset: lib/types -> lib/client.js + lib/index.js

scripts/build-client.mjs uses the client-bundle preset from a dsh source checkout (packages/client/tsdown.client.ts, default ..\..\deepseek-harness, override with $DSH_HARNESS or an argument). The preset resolves a package through packages/<group>/<dir>/package.json, so the script stages a temporary face package inside the checkout, links this repo's node_modules into it, runs tsdown for the Client face, normalizes the checkout path out of the emitted banners, copies the artifacts back and deletes the staging directory. The checkout itself is left untouched.

Verification

1. Types. devDependencies pins every @deepseek-ai/* package to the newer published generation (0.2.1-alpha.1), so pnpm run typecheck fails on any atom, prop or service that generation lacks. The three host folder APIs are intentionally absent from the published surface and are declared optional locally — that is what keeps the plugin compiling for both hosts.
2. Bundle surface. Diff the bundle against the host build: extract the host's own dsh/node_modules/@deepseek-ai/dsh-client-ui-workspace/lib/client.js from resources/app.asar, then compare the //#region lib/types/... module lists and the member sets required from each module-table entry (_deepseek_ai_dsh_client_ui_primitives.X, …dsh_client_store.X, _deepseek_ai_dsh_cordis.X, react.X, react_jsx_runtime.X), and check every required primitives symbol against the host's single export { … } list. Extra modules (the project editor) and extra members are fine only when the host exports them.
3. Runtime. Boot the host's own runtime against a throwaway profile with this bundle installed, then load the served UI in a headless browser and assert that the added features render: the 最近会话 / Recents section (the in-tree plugin has no such key), a workspace row menu that offers 编辑项目, a project editor dialog carrying 源文件夹 and 添加文件夹, and a console with no errors.

Known gaps

• "Set as primary" does not rewrite the host registry path. The shipped host has no such API. The plugin remembers the promoted directory, creates new Sessions there, and borrows them back by cwd; the host still treats the original path as the Workspace path. On a host with the folder API the action goes to the host and the path really changes.
• Folder membership is matched by Session cwd, and only Sessions the host left ungrouped are borrowed. A Session that the host already groups under its own Workspace stays there.
• src/ is vendored from winexeNew rather than hand-written: re-vendor it when moving to another host generation and keep the capability probes.
• No package tests; the in-tree suite stays in packages/client/ui-workspace/tests at the vendored revision.
