# bd (beads) pre-push hook
#
# This hook ensures that the database is exported to JSONL before pushing,
# preventing the problem where database changes are committed without
# corresponding JSONL updates.
#
# Installation:
#   cp examples/git-hooks/pre-push .git/hooks/pre-push
#   chmod +x .git/hooks/pre-push
#
# Or use the install script:
#   examples/git-hooks/install.sh

# Check if bd is available

if [ ! -d .beads ]; then

    exit 0
