dsh-file-pane
A VS Code/Codex-style file pane for the DeepSeek Harness (DSH) right sidebar: the tree stays on the right while files open on the left, with preview/pin tabs, line-aware file links, path copying, a right-click terminal, and Copy to Chat.

Screenshots
4-pane layout: viewer and file tree
4-pane layout. The original right pane is split into two: a viewer on the left and the Workspace file tree on the right. Three panes become four, and code and files stay side by side.
Copy to Chat: editor context menu and chat composer
Copy to Chat. Select code in the preview and right-click. The @file #Lx-Ly reference and the selected code are inserted into the composer, without sending.
Features
- File pane on the left — a file opened from the Workspace files tree lands in a pane to the left of the tree, so the tree stays visible on the right at a 70/30 split. If DSH cannot split or move the tab, it falls back to the stock behavior.
- Preview tabs, VS Code-style — a single click opens or replaces the one preview tab; a double click on a file (or on the tab) pins it. Preview tabs render in italics, and pinning is per session.
- Line-aware file links — a chat link to
src/app.ts:42 opens the file in the preview and scrolls to line 42. :12-20 and :12:5 (line:column) start at line 12; the native #L42 / #L42-L50 form works too.
- Copy paths — right-click a file or folder to copy its workspace-relative path (
src/app.ts) or absolute path; right-click empty space to copy the workspace root. Relative paths outside the workspace fall back to absolute.
- Open Terminal — right-click a file (it opens in the file's folder), a folder, or empty space in the tree to open a terminal there. The terminal opens as a sibling tab in the file pane, not over the tree.
- Copy / Copy to Chat — select text in the file preview and right-click. Copy keeps the native copy; Copy to Chat inserts a
@file #Lx-Ly reference plus the selected code as a fenced block into the composer, without sending it.
Example payload:
@src/app.ts #L12-L14
```ts
export const b = 2
```
Install
Tested with DSH 0.2.1-rc.5.
dsh plugin --profile desktop add github:sinvacn/dsh-file-pane
Or just ask the agent in chat:
Install the dsh-file-pane plugin: dsh plugin --profile desktop add github:sinvacn/dsh-file-pane
The agent runs the command for you (it needs shell access; approve the command if asked). Either way, dsh-file-pane is added to your profile and the sidebar row is registered automatically. If the plugin is off, enable it in Settings → Plugins.
Refresh the page once; restart the desktop app if the sidebar does not update.
Configuration
The default share for a new split is 0.7 (file/terminal pane on the left). Change it from the page console:
localStorage.setItem('dsh.file-pane.share', '0.7')
Values are clamped to 0.2–0.8. Existing splits keep their real ratio; drag a divider to adjust one.
Uninstall
Remove dsh-file-pane in Settings → Plugins, or run:
dsh plugin --profile desktop remove dsh-file-pane
Then refresh the page.
Limitations
- The right sidebar's total width cap is unchanged; existing splits keep their real ratio.
- If you keep the tree on the left yourself, files and terminals open in the right-hand sibling pane instead of swapping panes.
- Line ranges come from code and plain-text previews; Markdown/PDF previews insert the file reference and selected text without numbers.
- A file whose name literally ends in
:<digits> is treated as a line reference by chat links (rare).
- Copy to Chat only inserts into the composer; it never sends. Without a mounted composer, the payload is copied to the clipboard instead.
- The terminal changes into the target directory after it starts, so the
cd … command stays in shell history and scrollback.
