# This file represents the coding style enforced by Open MPI. This file
# is based on the long-held, but not enforced, guidelines from the
# beginning of the project. We will be requiring that all code going
# forward uses this style. To check your code before attempting to open
# a PR install clang-format and run your commits through clang-format.
#
# To install clang-format:
#
# macOS:
#   Homebrew: brew install clang-format
#   Mac Ports: port install clang
#
# Linux:
#   debian/ubuntu/rasbian: apt-get install clang-format
#   redhat/fedora: yum install clang-format
#
# To run against your code changes:
#
#   unstaged changes: git clang-format --style file -f
#   staged changes: git clang-format --style file
#
#   For interactive add the -p option.
#
# To run against all of Open MPI:
#
#   ./contrib/clang-format-ompi.sh
#
#   This command is intended to be run only once.
