I initially tried to use the existing .clang-format file, but it does not match the code style (at least with clang-format 11) and the formatting is not consistent across files. Therefore, I decided to rewrite the .clang-format with some personal preferences. Used command find . -iname "*.hpp" -o -iname "*.cpp" | xargs clang-format -i -style=file
