#
# bd (beads) pre-commit hook
#
# This hook ensures that any pending bd issue changes are flushed to
# .beads/beads.jsonl before the commit is created, preventing the
# race condition where daemon auto-flush fires after the commit.
#
# When sync.branch is configured, .beads changes are committed to a separate
# branch via worktree, so auto-staging is skipped for the main branch.
#
# Installation:
#   cp examples/git-hooks/pre-commit .git/hooks/pre-commit
#   chmod +x .git/hooks/pre-commit
#
# Or use the install script:
#   examples/git-hooks/install.sh

# Check if bd is available
if ! command -v bd >/dev/null 2>&1; then
    echo "Warning: bd command not found, skipping pre-commit flush" >&2
    exit 0
fi

# Check if we're in a bd workspace
if [ ! -d .beads ]; then
    # Not a bd workspace, nothing to do
    exit 0
fi

# Check if sync.branch is configured - if so, .beads changes go to a separate
# branch via worktree, not the current branch
# Use --json to get clean output (human-readable format prints "(not set)")
