Kategory VS Rope

Yeah, it has nice funcional capabilities and libraries (like Arrow[0]).

Last but not least, Scala is currently the language with one of the best effect systems in my opinion (https://zio.dev/). Kotlin for example has copied the approach with https://arrow-kt.io/ which I think is great actually. But when comparing Scala and Kotlin here, Scala wins by a large margin, it is a completely different world. It's like building a highly concurrent system in Erlang vs C.

Of course, if you don't want to learn things like union types, traits/typeclasses and effects (similar to async/await but more powerful) you will be annoyed by Scala. But once you learned them, you can never go back.

In my own code, I started to use explicit error handling. I'm currently experimenting with Result (from https://github.com/michaelbull/kotlin-result) and Raise (from https://arrow-kt.io/).

Are there any more-or-less established functional crates in Rust (similar to Kotlin’s Arrow)?

I wonder how the community sees adding Arrow besides standard Kotlin language features. Is it something that's still considered useful or just redundant and causing more confusion?

You can define a function like context(EitherEffect) suspend fun MyType.bind(path: String)like the ones in https://github.com/arrow-kt/arrow/blob/b608a054a5318fe57d7055c35bb64a5effb053b6/arrow-libs/core/arrow-core/src/commonMain/kotlin/arrow/core/computations/either.kt

If you're using Kotlin, I'd highly recommend looking into the https://arrow-kt.io library. It's quite a bit more sophisticated than the Dart FP libs, and meshes well with Kotlin. They've got a great website, but even better is their engagement on the #arrow channel on the kotlinlang.slack.com Slack.

Hi, maintainer of rope here. There are a number of different options to use rope in Vim/Neovim, we've documented them in this page https://github.com/python-rope/rope/wiki/Rope-in-Vim-or-Neovim

If you're looking for something with a bigger codebase, then the rope library in which pylsp-rope is based on is also welcoming of contributions.

I think rope is the standard for refactoring, and should provide autoimports soon, though pyright might also be good for that.

If you are interested in discussing this or have ideas you want to sketch out, meet me at rope's GitHub Discussion.

However, my biggest and most popular open source project is one that I don't originally write, but rather I inherited a popular project that has been abandoned by their original author/maintainers. I use Python a lot, so I wanted to contribute to the community in a significant way, so unlike my other projects I do take the time promoting this project as well. I felt it's more like a community service for this project.

I am the maintainer rope and pylsp-rope. They are libraries for automated Python refactoring and to do that from any LSP-capable editors. We are always welcoming contributors of all levels.

Rope has first class support for Vim and it can do a move refactoring, among other refactorings. From this, this feature is available from python-mode and ropevim.

Okay this depends: if your code is static: perfectly possible for example with https://github.com/python-rope/rope (used for example by VS Code). If it's dynamic / generated via metaprogramming: I never tried it but I can't imagine that it'd work there, yes. However java tooling also can't do that because it simply doesn't support metaprogramming in any noteworthy way.
