yuloop/dsh-web-split

中文 | English

Free split screen for DeepSeek Harness Web. Open a split view beside your normal work and keep two, three or four Sessions visible at once — each pane renders that Session's real conversation, input box included.

Features

• Sidebar entry — a 分屏 / Split button in the sidebar opens the split view as a main panel.
• Free layout — split right or down, drag a pane onto another to swap them, drag onto a pane's edge to move it there, drag the divider to resize, double-click the divider to flip the orientation and reset to 50/50.
• Fill panes from anywhere — drag a Session row from the sidebar into a pane, or use the row's own "放入分屏窗格 / Load into split pane" action, or the pane's context menu.
• Real conversations — every pane mounts the official conversation.content slot for its Session, so streaming, tools, attachments and the composer all behave exactly as they do in the normal view.
• Unread dots — the sidebar's unread indicator is mirrored onto the pane title, so you can see which pane is talking.
• Import running Sessions — one menu action arranges every running Session into panes (up to the pane cap) without closing anything. Sessions from a scheduler workspace are skipped (last cwd segment cron-jobs; see SCHEDULED_WORKSPACE in client.js).
• Persisted layout — the whole tree (panes, ratios, assignment) is kept in localStorage and restored on reload.
• Bilingual UI — Chinese and English strings ship with the plugin.
• No host-side behaviour — the host half only announces the client bundle; nothing in the Session domain is touched.

Install

The plugin is a bundle with a loader patch (cordis.patch.yml); install it like any other DSH plugin:

# straight from GitHub
dsh plugin --profile web add github:yuloop/dsh-web-split

# or from a local checkout
dsh plugin --profile web add /path/to/dsh-web-split

Restart DSH after installing, then reload the page. The sidebar shows the 分屏 entry.

cordis.patch.yml names the package (dsh-web-split). If you vendor the files into a local plugin directory instead, point its patch entry at the absolute path of index.js — that is how it runs on the machine it was developed on.

Known limitation

Clicking a file link or an image inside a pane shows an error dialog:

无法打开文件 / sidebarRight: no session surface is mounted

Reason: file links open the right sidebar through sidebarRight.require(), which only works for the Session that the shell currently has on screen. A global main panel carries no Session context, so the call throws. Panes still render and scroll their content; only the file/image preview is affected — open the file from the normal conversation view instead (click the Session in the sidebar, then use the link there).

This limitation is why the panel-based design is the stable release: a floating variant that keeps the conversation column active is developed separately and is not part of this release (it changes where the grid lives and needs the shell's shell.overlay seam).

Requirements

• DeepSeek Harness Web with the official UI packages (dsh-client-ui-layout, -session, -conversation, dsh-client-locale, dsh-api-session-controller).
• Developed against DSH 0.1.1-rc.2.

Layout

client.js          the whole web half (panel, pane tree, drag & drop, i18n, CSS)

cordis.patch.yml   loader patch fragment ("insert id: web-split")
package.json       manifest, including the dsh.client declaration
docs/DEVLOG.md     development log, day by day (Chinese, local notes)
