# clang-tidy configuration
#
# clang-tidy can be run manually like this:
#
#     run-clang-tidy -p build 'Source.*'
#
# To apply fixes suggested by clang-tidy, run:
#
#     run-clang-tidy -p build -fix -format 'Source.*'
#
# To limit the run to certain checks:
#
#     run-clang-tidy -checks='-*,modernize-use-nullptr' -p build 'Source.*'
#
# clang-tidy also has several IDE integrations listed here:
# https://clang.llvm.org/extra/clang-tidy/Integrations.html

# Enable most checks.
#
# Built-in checks:
# https://clang.llvm.org/extra/clang-tidy/checks/list.html
#
# Exclusions:
#
# -modernize-avoid-c-arrays
#   We use C-arrays throughout, e.g. for `constexpr char []`.
#   `std::array` is not a replacement because its length is
#   not deduced.
#
# -modernize-use-trailing-return-type
#   A purely stylistic change that we do not want.
#
# -modernize-concat-nested-namespaces
# -modernize-avoid-bind
#   Compatibility with older compilers.
