dsh-client-ui-git-branch

English | 中文

A dsh (DeepSeek Harness) out-of-tree plugin that adds a git branch selector to the chat composer, immediately left of the model seat (conversation.input.right).

Install

1. Install the plugin from npm (published as @dsh-mixxed/dsh-client-ui-git-branch):

   dsh plugin --profile web add @dsh-mixxed/dsh-client-ui-git-branch

   The package declares dsh.bundle (its bundled cordis.patch.yml), so dsh plugin add automatically appends it to the profile's dsh.profile.bundles layer stack and the plugin mounts on the next boot — no manual cordis.patch.yml editing.

   Upgrading an install that predates the bundle declaration: remove the legacy ui-git-branch row from $DSH_HOME/profiles/<name>/cordis.patch.yml — the bundle layer now supplies it, and leaving both would mount the id twice.

2. Restart the profile (new plugins are discovered at boot) and refresh the browser page. In a session whose workspace is a git repository, the branch chip appears left of the model seat.

Building from source (development / offline)

pnpm install
pnpm run typecheck
pnpm test
pnpm run build
npm pack          # produces dsh-mixxed-dsh-client-ui-git-branch-<version>.tgz
dsh plugin --profile web add ./dsh-mixxed-dsh-client-ui-git-branch-<version>.tgz

Features

• Composer seat left of the model selection, same chip/menu chrome as the model seat
• Shows only when git is installed and the session workspace is a git repository
• Fuzzy branch search (substring or in-order subsequence), with a clear button
• List shows at most 5 rows; more branches scroll inside the list (no page-level scrolling)
• Current branch marked in a distinct color (brand blue + check icon)
• Upstream tracking facts (VSCode-style): every branch shows its remote short name (origin/main) with colored ahead/behind commit counts (↑2 amber / ↓3 green) and a red gone marker when the upstream ref was deleted; local-only branches show nothing. The trigger chip carries the same badge when the current branch is out of sync
• Local / Remote groups — see Branch groups
• New branch action: a dialog asks for the branch name, then creates the branch from HEAD and checks it out (git switch -c); invalid names are flagged live, collisions surface git's message
• Branch switching with conflict detection: failures pop a transient toast carrying git's stderr
• Full zh / en i18n and automatic multi-theme support through --dsw-* design tokens
• Detached-HEAD safe (trigger falls back to HEAD); unborn-HEAD repos still list the current branch

Branch groups

The list is split under two sticky headings:

• Local branches — every local branch. Tracked branches keep their upstream mapping (master → origin/master, with ahead/behind counts).
• Remote branches — only branches that exist remotely but have no local counterpart (origin/HEAD symrefs and bare remote refs are excluded).

Behavior:

• The fuzzy search spans both groups at once; a group with no matches collapses away.
• Clicking a remote branch creates a local tracking branch and switches to it (git switch --track origin/feature → local feature tracking origin/feature); the branch then moves into the local group.
• Clicking a local branch switches the work tree (git switch); a blocked switch — typically uncommitted changes that would be overwritten — pops a toast with git's own message.

Verify

dsh --profile <name> --dump-config | Select-String ui-git-branch

The composed config shows the ui-git-branch row, and $DSH_HOME/profiles/<name>/package.json lists @dsh-mixxed/dsh-client-ui-git-branch under dsh.profile.bundles (auto-appended by dsh plugin add).

After the restart, the composer shows the branch chip; opening it reveals the grouped list, the search box, and the New branch action.

Development

pnpm run typecheck   # strict tsc over src + tests
pnpm test            # vitest: host logic (fake runner) + real-git integration + jsdom component tests
pnpm run build       # esbuild dual output → lib/index.js (node ESM) + lib/client.js (browser CJS closure)

Test profile used during development: git-branch-dev (independent of the user's web profile), booted with dsh --profile git-branch-dev --port 3800.
