Rope in Vim or Neovim

Audience: Rope user

There are a number of Vim integrations for using Rope:

Feature matrix (note: currently incomplete!):

Features	ropevim	python-mode	python-lsp-server (pylsp-rope)
Renaming	✔️	✔️	✔️1
Extract method	✔️	✔️	✔️2
Extract variable	✔️	✔️	✔️2
Move module/global/method	✔️	✔️	❌
Inlining	✔️	✔️	✔️
Use function	✔️	✔️	✔️
Restructure	✔️	❌	❌
Introduce Factory	✔️	❌	❌
Introduce Parameter	...	❌	✔️
Change method signature	✔️	✔️	❌
Transform module to package	...	...	❌
Encapsulate field	...	...	❌
Method to method object	...	...	✔️
Convert local variable to field	...	...	✔️
Organize Import	...	✔️	✔️
Generate variable/function/class	...	...	✔️

Footnotes:

1. Currently, python-lsp-server defaults to using Jedi for Renaming; you have to enable Renaming using the built-in Rope integration.

2. extracted variable/methods can only be created using default name by pylsp-rope, you can use the Rename refactoring afterwards to set the function name

LSP Setup

    \ 'name': 'pylsp',

Neovim Native LSP

Note: currently very buggy, not recommended for now
