I'd like to contribute

Hi guys,
I'd like to contribute to ndarray, is there any issues that I can work on to help me get familiar with the internal codes?

There are a few issues tagged with good first issue or help wanted. There's also a list of things in #597. I'd recommend asking before starting work on something, though, in case the relevant issue is out-of-date, and to discuss how to approach the implementation. As far as getting familiar with the internals of ndarray, it depends on what area you're interested in, since ndarray is a fairly large crate with a variety of functionality.

I mostly navigate the codebase with searching (ripgrep) and "go to definition", but these are a few pointers. The main type is ArrayBase, and the validity constraints for this type are described here. Most of the methods are implemented in src/impl_methods.rs. The various Data traits are in src/data_traits.rs. The Dimension trait is in src/dimension/dimension_trait.rs. Most of the slicing stuff is in src/slice.rs. Zip-related stuff is in src/zip/. The iterators are in src/iterators/.

Fwiw, I don't have much time myself to review PRs and suggest changes, so if the other maintainers are busy too, responses may be somewhat slow. Contributions are welcome, though.

I can explain that the src/impl_* convention is for all files that are part of impl ArrayBase. The many inherent methods of that type and its aliases are quite spread out, naturally.

Got it. Big thanks guys! @bluss @jturner314
