dsh-sidebar-expand-all
One-click expand all for the DeepSeek Harness sidebar — and a strict collapse to 5.
DSH 侧栏一次只展开 5 个会话；这个插件让「展开其余 N 个会话」点一次就展开该工作区全部会话，点「收起」严格回到 5 个。
中文说明见 README.zh.md。
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.
This plugin applies two 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 |
|---|
expand-all | visible.hiddenCount <= SESSION_WATERMARK_BASE ? Infinity : watermark + SESSION_WATERMARK_BASE | Number.POSITIVE_INFINITY | one click reveals every remaining session |
collapse-to-5 | Math.max(SESSION_WATERMARK_BASE, requiredWatermark(...)) | SESSION_WATERMARK_BASE | collapse always shows exactly 5 |
Both 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 patch status plus Apply, Restore and Refresh buttons.
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 two 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
lib/asar-patch.js is dependency-free and can be used outside the plugin.
