Run default checks on a source file:

clang-tidy {{path/to/file.cpp}}

Don't run any checks other than the cppcoreguidelines checks on a file:

clang-tidy {{path/to/file.cpp}} -checks={{-*,cppcoreguidelines-*}}

List all available checks:

clang-tidy -checks={{*}} -list-checks

Specify defines and includes as compilation options (after --):

clang-tidy {{path/to/file.cpp}} -- -I{{my_project/include}} -D{{definitions}}
