From ed44eee01d963fc385d314f646425d50d2710976 Mon Sep 17 00:00:00 2001 From: Jerry Xie Date: Sat, 28 Mar 2026 22:31:51 -0700 Subject: [PATCH 1/4] fix: check all git config scopes, not just --global The previous implementation only checked --global git config, but users may have their git identity configured in: - Local repository config (.git/config) - System config (/etc/gitconfig) - Other scopes This change first tries --global, then falls back to checking all scopes if --global returns empty. This ensures we detect git configuration regardless of where it's set.

This caused test failures when the user's actual dotfiles repo had uncommitted changes. Fix: Only check dotfiles repo state if at least one URL is configured. If both system and reference have empty dotfiles URLs, skip the git state check entirely. This makes the tests deterministic and not dependent on the user's local dotfiles repo state. --- internal/diff/compare.go | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/internal/diff/compare.go b/internal/diff/compare.go index 57c292f..c7f414c 100644 --- a/internal/diff/compare.go +++ b/internal/diff/compare.go @@ -171,6 +171,12 @@ func diffDotfiles(systemURL, referenceURL string) *DotfilesDiff { dd.RepoChanged = &ValueChange{System: systemURL, Reference: referenceURL} } + // Only check local dotfiles repo state if dotfiles are actually configured + // If both URLs are empty, there's no dotfiles setup to check + if sysNorm == "" && refNorm == "" { + return dd + } + // Check local dotfiles repo for dirty state home, err := os.UserHomeDir() if err != nil { From e3fd13511ca5ea419ba716f44ec64741c08b0964 Mon Sep 17 00:00:00 2001 From: Jerry Xie Date: Wed, 1 Apr 2026 00:34:20 -0700 Subject: [PATCH 4/4] fix: isolate diff tests via HOME env instead of production code guards Address PR #22 review feedback: -
