    # We follow the include order of Google's style guide (https://google.github.io/styleguide/cppguide.html#Names_and_Order_of_Includes)
    # with the addition of grouping third-party headers into (1) system headers (e.g., TBB or boost) or (2) submodule
    # headers located in ./third_party/.
    #
    # clang-format places includes into the first group (ordered by priority) where they match. Thus, it might mix TBB
    # or readline headers (both using .h) with system headers (e.g., pthread.h). Thus, before defining priority one, we
    # put TBB and readline headers into category 3 (i.e., third-party system headers).
    # headers.
  - Regex:           '^<(oneapi\/tbb\/.*|readline\/.*)>$'
    Priority:        3

  # C system headers as the first category (e.g., <stdlib.h>). Note: the parent/main header is implicitely priority 0.
  - Regex:           '^<.*\.h>'
    Priority:        1

    # See comment for TBB. Boost headers are not mixed with C headers but STL headers. As we cannot exclude <boost/...>
    # with clang-format's Posix extended regrexes, we first check for boost headers before turning to STL headers.
  - Regex:           '^<(boost\/.*|pqxx\/.*)>$'
    Priority:        3

  # STL headers as the second category (e.g., <vector>).
  - Regex:           '^<.*'
    Priority:        2

    # This list needs to be kept up to date to order non-system third party libraries properly. If third party files are
    # missed, it is not a real issue. They are simply grouped with Hyrise headers.
