# We disabled alias rules if they make nolinting findings a pain
#
# Disabled checks:
# altera-* : Performance oriented checks which are too low level for our scope
# llvm* : LLVM project specific checks and best practices not relevant for us
# boost-use-ranges : We prefer using the standard library whenever feasible
# bugprone-easily-swappable-parameters : Not helpful as we are not creating a library which users could misuse by accident
# clang-analyzer-cplusplus.NewDeleteLeaks : Too many false positives for using std::unique_ptr with C++11
# clang-analyzer-optin.core.EnumCastOutOfRange : We would like to use this, but this is incompatible to boost::regex and ExcludeHeaderFilterRegex is not working for clang-analyzer-*
# fuchsia-default-arguments-calls : Default arguments are often parts of established APIs, the check is too opinionated
# fuchsia-default-arguments-declarations : We prefer the lean usage offered by default values.
# hicpp-avoid-c-arrays : Alias to cppcoreguidelines-avoid-c-arrays
# hicpp-member-init : Alias to cppcoreguidelines-pro-type-member-init
# hicpp-no-array-decay : Alias to cppcoreguidelines-pro-bounds-array-to-pointer-decay
# misc-non-private-member-variables-in-classes : Alias to cppcoreguidelines-non-private-member-variables-in-classes
# modernize-avoid-c-arrays : Alias to cppcoreguidelines-avoid-c-arrays
# modernize-make-unique : Not compatible to C++11
# modernize-type-traits : Not compatible to C++11
# modernize-use-default-member-init : Alias to cppcoreguidelines-use-default-member-init
# modernize-use-nodiscard : Not compatible to C++11
# modernize-use-trailing-return-type : We prefer the classic style
# readability-function-cognitive-complexity : Too opinionated, we split up functions based on our own experience
# readability-magic-numbers : Alias to cppcoreguidelines-avoid-magic-numbers
# readability-redundant-member-init : We prefer a consistent initializer style, even if some of them are redundant
