How to check the rules

We check the rules using pre-commit (https://pre-commit.com/) framework. pre-commit can be installed via pip. After installing, run the following command in the root directory of the repository:

pre-commit install

This will create the hooks that perform the required formatting checks and will automatically run just before committing to flag issues.

Following conventional commits https://www.conventionalcommits.org/en/v1.0.0/#specification each commit must have a type from the following: build, ci, docs, feat, fix, perf, refactor, style, test, chore, revert, bump. In this format: [optional scope]: .

Commitizen (https://commitizen-tools.github.io/commitizen/) is used to do check that this standard is followed and is used in the pre-commit framework: pre-commit install –hook-type pre-push

This will create the pre-push hook that is going to check the commit message format before pushing to remote.

Hi @Martinfx, thank you for your contribution.

In README, can u add FreeBSD, probably with the (R) symbol as in others, under Supported Systems subsection as experimental?
Also, can u call it out under "Trademarks and Copyrights" subsection? Looks like their guidance in https://www.freebsd.org/copyright/trademarks/ says:

FreeBSD is a registered trademark of The FreeBSD Foundation.

Hi @Martinfx , sorry for the radio silence on this one. I made a comment which is the reason of the CI failure. You should also squash the commits into one as ComputeLibrary_squash_check job says above.

Also, can you rename your commit title and PR title as:

I think you need to run the pre-commit hooks to see this clang-format issue. Please have a look at @morgolock's message above.
