We should discuss on how we setup codespell here, as in regular skpkg packages we refer to ignore_words and ignore_lines in pyproject.toml, which doesn't exist here. I'm able to use the ignore_word file directly into pre-commit.yaml by making it a shell command (which force the comment symbol from ;; to # ), but I'm not sure how to add ignore_lines.

I would add a pyproject.toml. it only needs to have the [tool.black] and [tool.codespell] blocls in it. Nothing about building the package. Will this break setuptools for everything else if we do that?

cpplint would be good but let's get everything working first.

remove travis and conda recipe": correct

is there a reason why the tests are not funning on the PR? Do tests pass?

@sbillinge Thanks for the comments. This cpp library doesn't use setuptool, and I think adding a pyproject.toml is fine.

We never got the original tests to work, and I believe we discussed this before and decided to rewrite all tests using modernized cpp testing suits. All the tests on this for now depend on diffpy.srreal.
