Thank you so much for this! It saved my day months ago.
Now I have forked it since I need the version to match 6.0.0.
I couldn't find any Licence notice, so I hope you don't mind :)

I'm glad it was useful. You can use it and improve it.

I have another one for the 5.0.2 version but I never had to create one for the 6! :)

Hi @ffeu. Thanks for this. I'm stuck in the installation.
Could you please have a look and see if you can help me point the error at the top of your head.

The issue is I'm not able to move ahead of this step. It's over 4 hours since it has been cloning the repository.
I tried running brew install clang-format and it works fine. But the requirement dictates me to have version 7.0. Could you see what might be going wrong?
Thanks!

try taking a look where it clones the repository and try to do it manually (clone it manually), it's looks like the problem is related to that...

As llvm.org/svn seems not working (forbidden), one can use pre-built binary from https://releases.llvm.org/download.html

For example, for 7.0.0 and macOS:
