mzjqwq/dsh-sidebar-expand-all

One-click expand all for the DeepSeek Harness sidebar — expanded by default, with a strict collapse to 5.

DSH 侧栏默认只展开 5 个会话；这个插件让它默认全部展开，「展开其余 N 个会话」点一次展开该工作区全部剩余会话，点「收起」严格回到 5 个。

中文说明见 README.zh.md。

A note on the two run paths

If you run this from a DSH host plugin (the packaged /dsh-sidebar-expand-all control page), the code runs inside Electron, where node:fs resolves app.asar as a directory — statSync().isFile() is false and openSync() throws ENOENT. This package therefore reads the archive through Electron's original-fs (falling back to process.noAsar) whenever it detects process.versions.electron. If you patch from a plain terminal, the ordinary node:fs path is used instead. Both were verified against a real install.

The marketplace renders its install button with --profile web. On DSH Desktop, use --profile desktop instead — that is the profile the app actually boots.

What it changes

DSH stores a per-workspace "watermark": how many sessions of a group are visible. The upstream UI advances it by SESSION_WATERMARK_BASE = 5 on every click, and the collapsed baseline is raised whenever a running or unread session must stay visible.

That watermark lives only in React component state (useState({}) — not persisted, reset on remount), so patching just the click handler makes the sidebar fall back to 5 sessions after a restart. Hence the default is patched to Infinity too.

This plugin applies four same-length patches to the bundled client at

app.asar
└─ dsh/node_modules/@deepseek-ai/dsh-client-ui-workspace/lib/client.js

Patch	Official code	Patched code	Effect
toggle-all	the whole onClick (if (sessionsExpanded) { dropWatermarks(...); return; } plus the visible.hiddenCount <= SESSION_WATERMARK_BASE ? Infinity : watermark + SESSION_WATERMARK_BASE ternary)	setStoredWatermarks((marks) => ({ ...marks, [group.key]: sessionsExpanded ? SESSION_WATERMARK_BASE : Number.POSITIVE_INFINITY }))	one click reveals every remaining session; collapse writes back 5
collapse-baseline	Math.max(SESSION_WATERMARK_BASE, requiredWatermark(...))	SESSION_WATERMARK_BASE	collapse always shows exactly 5
default-expanded	const watermark = sessionWatermarks[group.key] ?? SESSION_WATERMARK_BASE;	... ?? Infinity;	expanded by default
default-expanded-drag	sessionWatermarks[group.key] ?? SESSION_WATERMARK_BASE).rows	... ?? Infinity).rows	drag ordering uses the same visible rows

All replacements are padded with spaces so the file size does not change, and the entry's integrity.hash (and blocks[0].hash) in the asar header is updated in place. Any change to file length would corrupt every following entry in the archive.

Install

From the plugin market / npm (after publishing):

dsh plugin --profile desktop add dsh-sidebar-expand-all

From a local checkout:

dsh plugin --profile desktop add ./dsh-sidebar-expand-all

Or add the repository directly:

dsh plugin --profile desktop add github:mzjqwq/dsh-sidebar-expand-all

Use

Web page

After DSH starts, open

http://127.0.0.1:<your DSH port>/dsh-sidebar-expand-all

You get the current status of all four patches plus Apply, Restore and Refresh buttons.

Installing the plugin does not modify anything by itself — it only serves this page and ships the CLI. Nothing is written to app.asar until you press Apply (or run the CLI without flags). Review what it will change first, then apply and restart DSH.

CLI

node scripts/patch-workspace-expand-all.mjs --check    # inspect only
node scripts/patch-workspace-expand-all.mjs            # apply (idempotent)
node scripts/patch-workspace-expand-all.mjs --list     # list built-in patches
node scripts/patch-workspace-expand-all.mjs --restore  # restore official file

Exit codes: 0 ok · 2 asar or backup missing · 3 file/header integrity mismatch (refused) · 4 check found inconsistent header.

Restart is required

The DSH host caches every client bundle in memory at startup, and dsh-client-hmr keeps seeing the startup-time stat of files inside app.asar, so editing the asar cannot hot-reload. Fully quit DSH and open it again (a page refresh is not enough).

Safety

• Files are never resized: patches are equal-length and verified by re-reading the entry and its header hash.
• The original client.js and the original asar header are backed up to ~/.dsh/dsh-sidebar-expand-all/.asar-bak/ before the first write (DSH_BAK overrides).
• Restore writes the backup back and re-checks that backup header and content match.
• If the current content does not match the header integrity (another tool already modified the archive), the apply step aborts instead of guessing.
• If a patch anchor is missing, the plugin reports unsupported and writes nothing — it never guesses a replacement.

Upgrades

A DSH upgrade replaces app.asar as a whole, so the patch disappears. Re-run Apply (or the CLI) after upgrading. If the anchors changed in a new DSH release, the status becomes unsupported; the four expressions above must then be re-located in the new client.js.

Bundled skill

The plugin also installs a user-level skill to ~/.dsh/skills/dsh-sidebar-expand-all/, so an agent session can perform the same check/apply/restore without the web page.

Development

node --check lib/asar-patch.js
node --check lib/index.js
node scripts/patch-workspace-expand-all.mjs --check   # read-only: is the patch applied?
node scripts/smoke-plugin.mjs                         # loads both halves, asserts the patch set fits

lib/asar-patch.js is dependency-free and can be used outside the plugin.
