mjnhmd/dsh-git-bar

A DeepSeek Harness bundle that adds one ambient row above the composer showing the Session's git context:

⎇ main · dsh-git-bar · 3 处改动 · ↑2 ↓1 · a1b2c3d

• repository name and root
• the branch the Session runs on, or 游离 HEAD / detached HEAD when the HEAD is not on a branch
• working-tree change totals (staged / unstaged / untracked in the tooltip)
• ahead/behind counts against the upstream branch
• short commit id — clickable, opening that commit on the origin remote (GitHub, GitLab and Bitbucket commit routes are all handled) — and a 链接工作树 / linked worktree marker when the directory is a linked git worktree, or a N 个工作树 marker when the repository has more than one
• every label is plain text: select it and copy it

The row refreshes every 8 seconds, on window focus, and when the Session changes. Reading it never touches the repository; two interactions deliberately do:

• click the branch — a searchable popover lists every local branch with its upstream, ahead/behind and dirty state, marks the current one, and can check one out or create a new branch from the current HEAD;
• click the change count — opens the working tree in the right-hand Sidebar as a 工作区改动 tab: the changed files, and the unified diff of the file you pick, untracked files included (diffed against /dev/null);
• click the worktree marker — lists every worktree of the repository with its branch and change count. 在此新建会话 opens a new Session in that worktree's directory (a worktree is a directory, so a Session is never moved between them), and 复制路径 copies it. A branch already checked out in another worktree is greyed out in the branch popover with the worktree that holds it, instead of failing with git's already checked out after the click.
• nothing here silently scrolls away: a drag that selects text does not also open a popover.

Install

From a Git checkout (pin the commit; add &path:/plugins/dsh-git-bar when the package is not at the repository root):

dsh plugin --profile desktop add "git+https://github.com/mjnhmd/dsh-git-bar.git#2d3e0408376127196a4c18e8b1e1c79389a166f5"

From npm, or from a local checkout during development:

dsh plugin --profile desktop add dsh-git-bar@0.1.0
dsh plugin --profile desktop add link:/absolute/path/to/plugins/dsh-git-bar

The Host half loads at startup, so restart the app after the first install; the Client half is served on the next page load.

Publish

Market index (add under 插件 → 发现 → 添加索引源): https://mjnhmd.github.io/dsh-git-bar/market/index.json

DSH ships no index of its own: a plugin market is a JSON file (format 1) you host yourself and add under 插件 → 发现 → 添加索引源. docs/market-index.example.json is a ready template, scripts/validate-index.mjs checks it against DSH's own validator, and docs/PUBLISH.zh.md walks through pushing the repository, publishing to npm, and publishing the index.

Host API

GET /dsh-git-bar/info?sessionId=<id>[&dir=<absolute path>]

• admitted through the harness browser session (ctx.connection.requestRejection), so it is unreachable without the GUI's own credentials;
• the directory comes from the Session store first; dir is only a fallback for a Session the store does not know, and must be absolute;
• replies with { dir, repository: null | { root, name, branch, detached, sha, commitUrl, remote, dirty: { changed, staged, unstaged, untracked }, upstream, ahead, behind, worktree: { linked, mainRoot, count } } };
• commitUrl is derived from the origin remote: the scp, ssh://, git:// and http(s) forms all normalize to https://host/owner/repo, and the commit route follows the host (GitHub /commit/, GitLab /-/commit/, Bitbucket /commits/). A local-path remote yields null and the id stays plain text.

GET /dsh-git-bar/branches?sessionId=<id> — { branches: [{ name, current, upstream, ahead, behind, subject, checkedOutIn }], dirty }, where checkedOutIn is the worktree path holding that branch (a branch can only be checked out in one worktree at a time).

GET /dsh-git-bar/worktrees?sessionId=<id> — { root, worktrees: [{ path, name, branch, detached, sha, bare, locked, prunable, main, current, dirty }] }, each worktree costing one status call for its own change count.

POST /dsh-git-bar/branches/checkout { sessionId, branch } — { branch, created: false }; 409 when git refuses (local changes, unknown branch).

POST /dsh-git-bar/branches/create { sessionId, name, from? } — { branch, created: true }; the name is validated with git check-ref-format --branch.

GET /dsh-git-bar/changes?sessionId=<id> — { files: [{ path, status, staged, additions, deletions }], dirty, truncated }, capped at 500 files.

GET /dsh-git-bar/diff?sessionId=<id>&path=<repo-relative>&staged=0|1 — { path, staged, diff, truncated }, capped at 200 000 characters.

Every git call uses an argument array (no shell), a 4 s timeout, and a 256 KiB buffer cap. Nothing is watched and nothing is cached.
