All code should be formatted using clang-format before committing.
Unfortunately Clang Format frequently has breaking changes with major releases
(which are tied to the Clang release cycle), which means we have to settle on a
specific version.
We currently use clang-format 6.0. Please make sure to use the correct version to avoid cluttering your diffs with unrelated format changes. Prebuilt binaries can be found here.
Please verify that all tests are green (run with make test or ctest) and
consider adding your own tests if possible.
