git-muster

Every branch, present and accounted for.

Git Muster is a compact command-line report for local Git branches. It separates worktree dirtiness from committed branch state, identifies what is published and what needs attention, shows linked worktrees, and adds pull-request status when the GitHub CLI is available.

Features

• One scannable report covering every local branch.
• Publication state derived independently from the configured upstream.
• Ahead, behind, diverged, local-only, and remote-gone states.
• Conditional linked-worktree names and checkout paths.
• Draft, open, approved, changes-requested, merged, and closed GitHub pull requests.
• Clickable, underlined PR numbers in supported interactive terminals.
• Responsive terminal layout plus stable plain output with ASCII interface glyphs for logs and pipes.
• Read-only operation with --no-fetch; no branch switching, deletion, merging, rebasing, or pushing.

Requirements

• Python 3.13 or 3.14
• Git 2.23 or newer, for git branch --show-current and for-each-ref's %(worktreepath)
• uv for the recommended installation
• Optional: an authenticated GitHub CLI for pull-request information

Install

Install the latest release from PyPI:

uv tool install git-muster

Use uv tool upgrade git-muster to update an existing installation.

The installed commands are equivalent:

git-muster
gm
git muster

For development from a clone:

git clone https://github.com/olearydj/git-muster.git
cd git-muster
uv sync --locked --all-groups
uv run git-muster --help

Usage

Run the report from anywhere inside a Git repository:

git muster

By default, Git Muster runs git fetch --all --prune --quiet before reporting so remote-tracking references are current. When that fetch fails, because the machine is offline or a remote no longer answers, the report still renders from the references already on disk and says that branch states may be out of date. Skip all network activity and repository mutation with:

git muster --no-fetch

Use ASCII without color or terminal hyperlinks for logs and pipes:

git muster --plain

The built-in help includes examples, effects, linked-worktree behavior, and a Rich branch-state reference:

git muster --help
git muster --version

Color, symbols, and width

Color, Unicode symbols, clickable repository identities, and clickable pull-request numbers appear when the report is written to an interactive terminal that can render them. GitHub repositories appear as owner / repository, with the owner and repository linked separately. The title includes [public], [private], or [internal] when GitHub reports visibility, [fork] when the repository is a fork, and [archived] when it is archived. A fork label links to its parent repository. Git Muster resolves the repository from origin, or another GitHub remote when origin is not hosted there, and honors the usual overrides:

--plain overrides all of them and uses ASCII interface glyphs without color or terminal hyperlinks. Repository-provided text, including branch, remote, and worktree names, is preserved and may contain Unicode. Git Muster also falls back to the ASCII glyph set on its own whenever the destination stream cannot encode its symbols, so its built-in decorations never cause an encoding failure.

Reading the report

Publication is deliberately separate from Git's configured upstream. A branch is recognized as published when it has a push destination or matching remote branch, even if it has no upstream or tracks a local parent branch. Git Muster retains both relationships internally but reports publication state by default.

When another linked worktree holds a branch, Git Muster shows its directory in the table and lists the full checkout path below it. It does not scan those other worktrees for dirtiness or change them.

GitHub integration uses one gh repo view query for canonical identity, visibility, fork parent, and archive state, plus one optional gh pr list --state all --limit 100 query for pull requests. A branch whose pull request falls outside the hundred most recent is reported without pull-request state. When several pull requests share a head branch, the newest open, draft, approved, or changes-requested one wins over closed and merged ones. Without an installed and authenticated gh, or when no remote points at a known GitHub host, the complete Git report still works, falls back to identity parsed from the remote URL, omits metadata it cannot establish, and names the reason pull-request state is missing.

Safety and scope

Git Muster reports; it does not manage branches or worktrees. It never switches, deletes, merges, rebases, or pushes branches. Its only default repository mutation is refreshing remote-tracking references with git fetch --all --prune; --no-fetch makes the entire run read-only.

Git Muster intentionally has no configuration file, interactive browser, branch tree, cleanup command, or plugin system.

Development

Runtime dependencies are limited to Typer and Rich. Repository inspection uses the standard library and Git CLI, while tests create disposable local repositories and stub GitHub responses.

uv sync --locked --all-groups
uv run --locked pytest
uv run --locked ruff format --check .
uv run --locked ruff check .
uv run --locked ty check
uv build

See CONTRIBUTING.md before opening a pull request. CI runs the same checks on Python 3.13 and 3.14.
