I finally got it…
I know it’s an old thread, but in case someone else does have a similar problem:
Download and install clang-format configurator and you can define your own format behaviour.
Getting started with Clang-Format Style Options.
I used the WebKit-Clang-Format-File as template and adjusted it a little bit. My .clang-format file.
How to use:
Just copy the .clang-format file into the root/source directory of your c++ project. Ensure Clang-Format support in visual studio is active (see screenshot of my previous post, ignore the red circle ^^).
