.clang-tidy

# Configuration file to be used with clang-tidy

# This file is automatically discovered by clang-tidy when you run it on a
# file in a subdirectory.
#
# This is based on https://github.com/dealii/dealii/blob/master/.clang-tidy
#
# Usage:
#
# see ./contrib/utilities/run_clang_tidy.sh
#
#
#
# alternatively:
#
# set DEAL_II_DIR to an installation made with clang:
#
# export SRC=$PWD
# rm -rf build; mkdir build; cd build
# CXX=clang++ CC=clang cmake -DCMAKE_CXX_CLANG_TIDY="clang-tidy;-fix;-quiet;-header-filter=$(realpath ..)" $SRC
# make -j 4
#
# alternatively (older cmake versions):
# export SRC=$PWD
# rm -rf build; mkdir build; cd build
# cmake -G Ninja -D CMAKE_EXPORT_COMPILE_COMMANDS=ON $SRC
# run-clang-tidy.py -p . -quiet -header-filter="$SRC/include/*"



# Rationale for disabling warnings:
#
# - modernize-concat-nested-namespaces: This is c++17 only.
# - performance-inefficient-string-concatenation: We don't care about "a"+to_string(5)+...
# - performance-no-automatic-move: All modern compiler perform the return value optimization and we prefer to keep things const.
# - modernize-return-braced-init-list: it makes sense to be verbose.
# - performance-enum-size,-performance-avoid-endl: this should not matter much
# - modernize-avoid-bind: We use std::bind() in core.cc where replacement doesn't make sense (astyle fails to format)
