.clang-format

# Centralized coding style defines for the esnacc compiler
# The initial code uses pretty wierd coding style and did not enforce any dedicated style so this is the aim to achive a common same style for all the files
#
# The file requires a pretty new clang format, at least 18.
# At the time of writing the document it is based on 18.1.8
