File Helpers

DKUtil::Config provides some helper functions for files:

• To get full path of config file, relative or not:

std::string GetPath(const std::string_view a_file);

• To list all files fulfilling the criterion:

template <bool RECURSIVE = false>
std::vector<std::string> GetAllFiles(
    std::string_view a_dir = {}, 
    std::string_view a_ext = {}, 
    std::string_view a_prefix = {}, 
    std::string_view a_suffix = {});
