# bd (beads) post-checkout hook
#
# This hook syncs the bd database after a branch checkout:
# 1. Checks if any .beads/*.jsonl file was updated
# 2. Runs 'bd sync --import-only' to import changes
#
# Arguments provided by git:
# $1 = ref of previous HEAD
# $2 = ref of new HEAD
# $3 = flag (1 if branch checkout, 0 if file checkout)
#
# Install: cp examples/git-hooks/post-checkout .git/hooks/post-checkout && chmod +x .git/hooks/post-checkout

# Only run on branch checkouts
if [ "$3" != "1" ]; then
    exit 0

# Check if bd is available
if ! command -v bd >/dev/null 2>&1; then
    exit 0

# Check if we're in a bd workspace

# Check if any JSONL file exists in .beads/
if ! ls .beads/*.jsonl >/dev/null 2>&1; then

# Run bd sync --import-only to import the updated JSONL

# This catches version mismatches, outdated hooks, etc.
