dsh-history — DSH Web command history plugin

Remembers the current session's command history in the DSH Web GUI: with the composer input focused, press ↑ / ↓ to step through previously sent commands, edit them, and press Enter to re-send.

✨ Features

• Recording — every message you send in the current session (plain messages and /xxx slash commands) is recorded automatically, isolated per session. History is derived from the session log (user/command nodes), so it is rebuilt automatically after a page reload — no extra storage needed.
• ↑ — step back to the previous command; keep pressing to go further back. The first press saves the draft you were editing, and pressing ↓ afterwards returns to it.
• ↓ — step forward to a newer command; from the newest entry, one more ↓ returns to the saved draft.
• Edit & re-run — a recalled command lands in the composer draft; edit it directly and press Enter to re-send.
• Safe fallbacks — while a / or @ trigger menu is open, during IME composition (e.g. Chinese input), when the composer is busy/locked, or when the input is not focused, ↑/↓ keep their native behavior and never interfere.

📦 Installation

The plugin is a standard DSH static plugin (see the develop/basic tutorial). The entry name must be the bare package name dsh-history, and the package directory must be resolvable from both resolution trees (the host loader resolves the bare name from the DSH installation's node_modules; the client-modules scanner resolves dsh-history/package.json upward from the profile directory), so two symlinks are required:

# 1) profile side (client-modules scanner): $DSH_HOME defaults to ~/.dsh
ln -s /absolute/path/to/dsh-history ~/.dsh/profiles/node_modules/dsh-history

# 2) install side (host loader bare-name resolution): point to the dsh installation's node_modules
ln -s /absolute/path/to/dsh-history /home/ender/.npm/_npx/1e7f6d9597241db0/node_modules/dsh-history

Then launch with the patch:

dsh web --patch /absolute/path/to/dsh-history/cordis.yml

Or merge the cordis.yml contents (the insert stanza) into $DSH_HOME/profiles/web/cordis.patch.yml to load it permanently.

⚙️ How it works

• Client-module mechanism — the package declares dsh.client: { platform: "web" } with exports["./client"] pointing at lib/client.js; dsh-client-modules then bundles that entry into window.__DSH_BOOT__ and serves it at /plugins/<entry>/client.js. The browser side registers the plugin through window.__ModuleLoader__.load({ id, factory }).
• Recording — a component registered on the conversation.input.dock slot subscribes to the session snapshot (useSession((s) => s.nodes)) and incrementally scans user/command nodes by seq (the list is seq-ascending and untruncated), collapsing adjacent duplicates, capped at 100 entries, stored in a module-level Map<sessionId, …>.
• Navigation — a capture-phase keydown listener on document takes over ↑/↓ only when the focus is inside [data-composer-card], no trigger menu is open (claim is empty), not composing IME input, no modifier keys are held, and the composer is not busy — writing the draft via inputActions.setDraft(text). The editing check returns you to the live position automatically after you type.
• Indicator — while browsing, a small “history n/m” badge is shown above the composer.

⚠️ Limitations

• History is per-session and in-memory (rebuilt from the session log after a page reload, so nothing is lost within a session; it is discarded when the browser closes).
• Slash commands are recalled as /name args (from command nodes).
• Image-only messages (no text) are not recorded.
