dsh-plugin-terminal

English | 中文

A DeepSeek Harness (DSH) Web
plugin that adds a real interactive terminal — a VS Code-style collapsible
panel docked to the footer. This plugin runs an actual shell in a PTY
and streams the raw terminal bytes to the browser. It is a persistent bundle
plugin (a host half plus a browser half) that loads on every boot.

Demo

What it does

• Actual terminal — a real interactive shell (PowerShell on Windows,
  $SHELL//bin/bash elsewhere, by default) running in a PTY via the harness's
  subprocess.spawnTerminal primitive (node-pty).
• Full terminal rendering — xterm.js renders ANSI colors, cursor movement,
  full-screen apps (vim, htop, top, …), and 256-color output.
• VS Code-style footer panel — a collapsible bottom panel with a header,
  drag-to-resize top edge, restart button, and collapse toggle.
• Keyboard shortcut — `Ctrl+ toggles the panel (the VS Code default).
• Live resize — the PTY reflows when you resize the panel.
• A Terminal settings card under Settings → Plugins configures theme, font
  size, panel height, opacity, start-collapsed, shell, and working directory at
  runtime.
• Graceful fallback — if xterm.js cannot load (offline), a plain streaming
  view still exposes the real shell.

Files

Install

dsh plugin --profile web add github:mervyn-teo/dsh-plugin-terminal

Then restart dsh web — host bundles load at boot.

Defaults live in cordis.patch.yml. Change them there (or in the profile's own
cordis.patch.yml) and restart, or adjust them at runtime from the settings
card. The host half serves two same-origin routes the browser half uses:
GET|POST /api/terminal/config and the /api/terminal WebSocket upgrade.

Requirements

• DSH with the subprocess and webServer services mounted.
• Network access to jsDelivr the first time the terminal renders xterm.js
  (the plain fallback works without it).

Settings

Settings → Plugins → Terminal exposes:

Shell and working directory apply the next time you open the terminal; theme,
opacity, font size, and max height apply immediately.

Notes and limitations

• The terminal renders xterm.js from the jsDelivr CDN; the first expansion
  requires network access. The plain fallback still works offline.
• A session is process-local and does not survive a harness restart.
• The WebSocket route is loopback-bound like the rest of the Web GUI.
• Windows — on Windows the default shell is powershell.exe (set shell to
  cmd.exe for Command Prompt, with shellArgs: []). It needs a Windows-built
  node-pty (conpty/winpty) from the DSH host.
