dsh-chatflow-rail

中文 | English

A plugin for the dsh web GUI that adds a conversation-flow navigation rail on the left of the chat — one dash per user message, positioned 1:1 against the real content — plus a previous-message card docked at the top.

Screenshots

Instead of scrolling through a long transcript to find where you were, the rail gives you the whole conversation as a map: a tight cluster of dashes, each one a user message, and hovering fans the cluster out — dashes near the pointer widen and darken with a smooth falloff. Crossing the preview threshold floats a card with #N/M · time and the message content. Click a dash — or anywhere on the rail — and the view eases smoothly to that message, landing below the top card.

When you scroll a user message above the viewport, a native-styled floating card at the top shows 上一消息 #N/M · time with a 3-line preview; click it to jump back. The card is a floating overlay in the shell's click-through layer: the empty state is fully transparent, so the top of the conversation stays clean and nothing is reserved when there is nothing to show. Steering follow-ups (messages sent while a run is active) count as anchors too, and the plugin auto-expands dsh's history window so the rail covers the whole conversation — not just the tail window the transcript renders.

Install

The plugin is a git-hosted bundle whose build script pnpm blocks by default, so first allow it in the web profile's workspace file, then add the package.

# 1. Allow the plugin's build (prepare) script — add to
#    ~/.dsh/profiles/web/pnpm-workspace.yaml:
#      onlyBuiltDependencies:
#        - dsh-chatflow-rail

# 2. Install from the GitHub repo (prepare builds lib/ on install;
#    lib/ is a build artifact and not committed)
dsh plugin --profile web add github:veritas501/dsh-chatflow-rail

# 3. Restart dsh web, then refresh the page
dsh web

Notes:

• dsh plugin behaves like adding a dependency to your web profile. A bundle plugin is loaded once its full package name appears in the profile's dsh.profile.bundles list (recent dsh builds add it automatically; add it manually if yours does not). The bundle patch applies on the next boot, and the browser picks up the new bundle revision on refresh.
• Developing the plugin itself? Install from a local checkout instead: pnpm build first, then dsh plugin --profile web add file:/path/to/dsh-chatflow-rail.
• The rail is drawn by the browser half (dsh.client → lib/client.js); the Node half (lib/index.js) is a no-op so the loader's root-module contract is satisfied.

Development

• pnpm run build — emits the browser bundle (lib/client.js) and the Node half (lib/index.js) via tsc + tsdown.
• src/client/model/* — React-free pure logic (geometry, layout, chip selection, smooth scroll, anchor collection, paging); tunables live in src/client/model/constants.ts.
• src/client/view/* — TSX components and CSS Modules (compiled by lightningcss, injected as style[data-plugin="dsh-chatflow-rail"]).
• pnpm test — vitest behavior tests for the model layer; pnpm run typecheck — type gate.
• A --dev dsh web server hot-reloads rebuilt bundles — pnpm run build alone is usually enough to see changes.
