# This script assists with using clang-tidy.

# STEP 0;
# I recommend downloading or building the latest
# version of llvm with clang and the clang-tidy
# tools in a private repo. NOTE: Apple does
# not currently distribute these.
#
# STEP 1:
# Build your source tree with cmake and use
# export PATH=${MYCLANG_FROM_STEP0}:$PATH
# export CXX=${MYCLANG_FROM_STEP0}
# export CC=${MYCLANG_FROM_STEP0}
# cd ${MYBLD}
# cmake -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=ON ${MYSRC}
# to generate the compile_commands.json
# comple options database files.
#
# STEP 2:
# Run clang-tidy with the

PERF: readability container size empty
The emptiness of a container should be checked using the empty() method
instead of the size() method. It is not guaranteed that size() is a
constant-time function, and it is generally more efficient and also
shows clearer intent to use empty(). Furthermore some containers may
implement the empty() method but not implement the size() method. Using
empty() whenever possible makes it easier to switch to another container
in the future.
