Hello everyone,

As we recently [bump the CXX version from C++11 to C++17](https://gitlab.kitware.com/vtk/vtk/-/merge_requests/11049), I just updated the [coding convention for C++17](https://docs.vtk.org/en/latest/developers_guide/coding_conventions.html).

Please take the time to read this document before your next contribution 🙂 if you have any question regarding these conventions you can ping me (@lucas.givord), sankhesh (@sankhesh) or mathieu (@mwestphal) directly on your merge request.

Hey I would like to follow the style guidelines. Is there a `.clang-format` file which we can use to enforce the style automatically?

Yes, it is in the repo already. However, keep in mind not everything can be enforced by clang-format.
