refactor VS Rope

Indeed! I also would suggest people to use a CST implementation (parso / LibCST) instead of refactor if they intend do large scale refactors, but from what I can see in my previous attempts (e.g teyit, a unittest assertion formatter) when you deal with small code fragments (a single expression, or a small statement) then you generally don't need to worry much about the style. The only concern is the literals (especially strings, which there are a few different variations of the same AST) where you could resurrect them back from the token stream (which the CustomUnparser representative in refactor allows).

The real start point for this project was to find / replace all type()'s in CPython codebase with type(type()) (e.g type('') would become type(str)) which is very light weight transformation, and I was able to write a script which did it without having any major problems about style on over 2000 files. Here it is for the reference: https://github.com/isidentical/refactor/blob/master/examples...

Also one thing to note here is that; in the last couple of years, thanks to black (and yapf), the adoptance of code formatters have really increased which is very nice for custom refactoring tools like refactor since the end-code would be refactored anyways so that means if you convert a multi line call, or a list to a single line version then the formatter you use probably reformat that segment anyways.

But thanks for authoring Bowler! It is a very cool project.

I've just released 0.2.0 version of refactor, https://github.com/isidentical/refactor, which features additional information collection from the surrounding code.

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.
