# The column limit.
# A column limit of 0 means that there is no column limit. In this case, clang-format will respect the input’s line breaking decisions within statements.

# Format compatible with this standard, e.g. use A<A<int> > instead of A<A<int>> for LS_Cpp03.
# Possible values:
#     LS_Cpp03 (in configuration: Cpp03) Use C++03-compatible syntax.
#     LS_Cpp11 (in configuration: Cpp11) Use features of C++11 (e.g. A<A<int>> instead of A<A<int> >).
#     LS_Auto (in configuration: Auto) Automatic detection based on the input.
Standard: Cpp11

# Regular expressions denoting the different #include categories used for ordering #includes.
#  - POSIX extended regular expressions are supported.
#  - These regular expressions are matched against the filename of an include (including the <> or "") in order.
#  - The value belonging to the first matching regular expression is assigned and #includes are sorted
#    first according to increasing category number and then alphabetically within each category.
#  - If none of the regular expressions match, INT_MAX is assigned as category.
#  - The main header for a source file automatically gets category 0 so that it is generally kept at
#    the beginning of the #includes (https://llvm.org/docs/CodingStandards.html#include-style).
#    However, you can also assign negative priorities if you have certain headers that always need to be first.
#
# NOTE: Include here all regex to fulfill Google style guide -> https://google.github.io/styleguide/cppguide.html#Names_and_Order_of_Includes
