clang format

If you arrived here due to a lint error, running the command given in the message will fix your problem.

This wiki covers how to set up clang-format as part of your workflow.

1. Add tools/git-clang-format to your $PATH. This is a modified version of the default git integration that fetches a pinned binary guaranteed to work with the CI and other PyTorch developers. Once its added to your $PATH, running git clang-format will invoke it.
2. To ensure your changes are always formatted, you can add git clang-format to your a pre-commit hook. PyTorch provides a pre-commit hook (instructions) that runs our standard linters, or you can make your own that just format:

# run in pytorch root
cat <<\EOF > .git/hooks/pre-commit
#!/bin/bash
set -e
git clang-format
EOF

chmod 755 .git/hooks/pre-commit
