PREAMBLE: |
If you are reading this, you are looking at a failed Github Actions
job. That means you pushed one or more files that did not conform
to the formatting specified in .clang-format. That may be because
you neglected to run 'git clang-format' or 'clang-format' before
committing, or that your version of clang-format has an
incompatibility with the one on this
machine, which is:
SUGGESTION: |
To fix it, you can do one of two things:
1. Download and apply the patch generated as an artifact of this
job to your repo, commit, and push.
2. Run 'git-clang-format --extensions c,cpp,h,cxx,ipp develop'
in your repo, commit, and push.
