# This file is provided for developer convenience.

# The recommended way to format Autoware.Auto code is as follows:
# (optional) ament_clang_format --config ../AutowareAuto/.clang-format --reformat foobar.cpp
# ament_uncrustify --reformat foobar.cpp
# ament_cpplint foobar.cpp
# Fix errors stated
# Repeat previous 4 steps until ament_uncrustify and ament_cpplint give no more errors.
