From dbf68bac59af47cd1adfa0b2317391c8315f8fad Mon Sep 17 00:00:00 2001 From: Vijay Misal Date: Mon, 17 Aug 2026 11:45:48 +0530 Subject: [PATCH] fix(is-git-repo): recognize bare repositories (#1266) * fix(is-git-repo): recognize bare repositories is_git_repo() used `git rev-parse --show-toplevel` to detect whether the current directory is inside a git repository. --show-toplevel fails for bare repositories since they have no working tree, so every command that relies on this shared helper (e.g. `git browse`) reports "Not a git repo!" when run from inside a bare repo, even though it plainly is one. Switch to `git rev-parse --git-dir`, which succeeds for both normal and bare repositories and keeps the existing "not a repo" behavior for non-repo directories. Fixes #1238, reported and LGTM'd by maintainers there with this exact fix; no PR had been opened for it yet. Adds tests/is-git-repo.bats covering: a normal repo, a bare repo, and a plain (non-repo) directory. * Fix ruff lint failures in scripts/checkstyle.py This PR's new Ruff CI job surfaced pre-existing style issues (unsorted imports, deprecated typing.List/Dict, nested ifs, bare exit()) in checkstyle.py. Cleaned these up so the newly added lint job passes.
