dsh-jj-panel

English | 简体中文

A Jujutsu history panel for the DeepSeek Harness web GUI. It reads jj directly — no git translation — and shows the change graph, change details, changed files and diffs in its own Jujutsu tab, and shapes history through the same jj-native workflow.

Features

• Change tree — jj log rendered as lanes: change IDs, commit IDs, bookmarks, tags, empty / conflict / divergent markers, the @ working-copy commit, and the main (or master) trunk lane highlighted.
• Change details — full description, author and timestamp, changed files with their status (M/A/D/R).
• Diffs — click a changed file to load its jj diff --git output with +/- colouring.
• Revset box — the panel loads all() by default (switch to ::@ to focus the current stack); type any revset (all(), bookmarks(), description("…")) and press Enter.
• Structural editing — right-click (or the ⋯ button) for new change here, edit, describe, squash into parent, abandon (or the whole subtree), duplicate, revert before @, split by file, copy change id, and push a bookmark.
• Drag to rebase — drag one row onto another to rebase it; hold Alt to insert the change before the target (reorder a stack). Drops onto the change itself or its descendants are ignored.
• Split by file — toggle split mode in the change details, tick files, then "Split into new change": the ticked files move into a new child of the current @ change, and the original keeps its description.
• Undo / Fetch — toolbar actions; destructive operations (abandon, subtree abandon, revert, undo, push) open an inline confirmation naming the action and target change before any write.
• Keyboard — j/k move the selection, Enter edits, n creates a new change on the selection, u asks to undo, / focuses the revset box.

Requirements

• DSH 0.2.1-rc.2 or newer within the 0.2.x line (web profile).
• jj 0.44+ on PATH, or configure jjPath.
• The workspace must be a Jujutsu repository (jj git init --colocate in an existing git repo works).

Install

dsh plugin --profile web add dsh-jj-panel

Or from a checkout:

dsh plugin --profile web add file:D:\path\to\dsh-jj-panel

After installing, open the Jujutsu tab next to the other conversation views. Host-side changes need a DSH restart; the browser half hot-reloads.

Plugin market source

This repository ships a format-1 market index at market/index.json. Add this URL as a market source under Plugins → Discover to install the pinned version:

https://raw.githubusercontent.com/wzciczw/dsh-jj-panel/master/market/index.json

The index is validated against @deepseek-ai/dsh-plugin-market-index in the test suite.

Configuration

The plugin accepts an optional config block (profile cordis.patch.yml or the plugin settings page):

- id: jj-panel
  name: "dsh-jj-panel"
  config:
    jjPath: 'C:\path\to\jj.exe'   # default: PATH, then the winget install location
    timeoutMs: 8000               # per jj command
    maxBytes: 4194304             # stdout cap
    defaultLimit: 120             # commits per load (1..500)

How it works

• Host half: a Cordis plugin registering a TypertRemoteService named jjPanel with five Remote methods — snapshot, log, show, diff and op. Every command is spawned as an argv array, never through a shell.
• Browser half: a React panel registered on conversation.view, talking to the host through connection.rpc.call(rpc, "/api", "jjPanel", …).
• Data comes from a jj log --no-graph -T … template (change id, commit id, parents, bookmarks, tags, flags, description first line); details use jj show --no-patch -T 'json(self)'.
• Every structural edit goes through jjPanel/op with an action plus params; the host builds the argv and returns stdout, which the panel shows in its status line.

Safety

• Writes are limited to the allowlisted op actions; the browser half never constructs jj commands.
• Abandon, subtree abandon, revert, undo and push require confirm: true; the panel asks first and the host rejects unconfirmed calls.
• Revsets are validated (no -- / global flags); paths must stay inside the repository.
• Output is capped and commands time out; failures surface verbatim in the panel, and Undo (jj undo) is always one toolbar click away.

Development

npm install
npm run build      # tsc (host) + tsc (client) + bundle lib/client.js
npm test           # build + unit/integration tests (real jj when available)

The integration tests use JJ_TEST_REPO when set, otherwise D:\agent-research.
