C++

C++ code should conform to Google C++ Style Guide.

HierarchicalKV uses clang-format to check your C/C++ changes. Sometimes you have some manually formatted code that you don’t want clang-format to touch. You can disable formatting like this:

int formatted_code;
// clang-format off
    void    unformatted_code  ;
// clang-format on
void formatted_code_again;

Install Clang-format (the version 18.1.3 is required) for Ubuntu:

sudo apt install clang-format-18

format all with:

find ./ \( -path ./tests/googletest -prune \) -o \( -iname *.h -o -iname *.cpp -o -iname *.cc -o -iname *.cu -o -iname *.cuh -o -iname *.hpp \) -print | xargs clang-format-18 -i --style=file
