Git pre-commit check to stop accidental commits to master/main/develop branches.
# This gist contains pre-commit hooks to prevent you from commiting bad code or to the wrong branch.

# - pre-commit-5: elixir formatting check.
# - pre-commit-6: prettier formatting check.
# Set the desired version like this before proceeding:
