@ThomsonTan unfortunately on my mac format produces crazy results (maybe some hints on how to properly run would be appreciated), is it possible to help me with formatting this code?

@bogdandrutu - You can do this by

• installing and running clang-format-10. This is the default package in ubuntu 20.04. So you can create ubuntu:20.04 docker container to do the format. refer - https://github.com/open-telemetry/opentelemetry-cpp/blob/v1.12.0/ci/install_format_tools.sh)
• copy and apply the patch given by the format failure in the build logs.

@bogdandrutu you could use docker:

./ci/run_docker.sh  tools/format.sh

[bogdandrutu]

@esigo that is awesome, but not documented :) Thanks

[marcalff]

LGTM, thanks for the fix.

[owent]
