# To run clang-tidy from CMake, build ClickHouse with -DENABLE_CLANG_TIDY=1. To show all warnings, it is
|
|
# recommended to pass "-k0" to Ninja.
|
|
|
|
# Enable all checks + disable selected checks. Feel free to remove disabled checks from below list if
|
|
# a) the new check is not controversial (this includes many checks in readability-* and google-*) or
|
|
# b) too noisy (checks with > 100 new warnings are considered noisy, this includes e.g. cppcoreguidelines-*).

# warning `readability-redundant-member-init` does the opposite thing, both are not compatible with each other.
