Extended refactoring capabilities for Python LSP Server using Rope.

pylsp-rope

Extended refactoring capabilities for Python LSP Server using Rope.

This is a plugin for Python LSP Server, so you also need to have it installed.

python-lsp-server already has basic built-in support for using Rope, but it's currently limited to just renaming and completion. Installing this plugin adds more refactoring functionality to python-lsp-server.

Installation

To use this plugin, you need to install this plugin in the same virtualenv as python-lsp-server itself.

pip install pylsp-rope

Then run pylsp as usual, the plugin will be auto-discovered by python-lsp-server if you've installed it to the right environment. On Vim, refer to Rope in Vim or Neovim. For other editors, refer to your IDE/text editor's documentation on how to setup a language server.

Configuration

Features

This plugin adds the following features to python-lsp-server:

• extract method (codeAction)
• extract variable (codeAction)
• inline method/variable/parameter (codeAction)
• use function (codeAction)
• method to method object (codeAction)
• convert local variable to field (codeAction)
• organize imports (codeAction)
• introduce parameter (codeAction)
• generate variable/function/class from undefined variable (codeAction)
• more to come...

Refer to Rope documentation for more details on how these refactoring works.

Usage

Extract method

Variants:

• Extract method
• Extract global method
• Extract method including similar statements
• Extract global method including similar statements

When CodeAction is triggered and the cursor is on any block of code, extract that expression into a method. Optionally, similar statements can also be extracted.

Extract variable

Variants:

• Extract variable
• Extract global variable
• Extract variable including similar statements
• Extract global variable including similar statements

When CodeAction is triggered and the cursor is on a expression, extract that expression into a variable. Optionally, similar statements can also be extracted.

Inline

When CodeAction is triggered and the cursor is on a resolvable Python variable, replace all calls to that method with the method body.

Use function

When CodeAction is triggered and the cursor is on the function name of a def statement, try to replace code whose AST matches the selected function with a call to the function.

Method to method object

When CodeAction is triggered and the cursor is on the function name of a def statement, create a callable class to replace that method. You may want to inline the method afterwards to remove the indirection.

Convert local variable to field

When CodeAction is triggered wand the cursor is on a local variable inside a method, convert that local variable to an attribute.

Organize import

Trigger CodeAction anywhere in a Python file to organize imports.

Introduce parameter

When CodeAction is triggered and the cursor is selecting a Python variable or attribute, make that variable/attribute a parameter.

Generate code

Variants:

• Generate variable
• Generate function
• Generate class
• Generate module
• Generate package

When CodeAction is triggered and the cursor is on an undefined Python variable, generate an empty variable/function/class/module/package for that name.

Caveat

Support for working on unsaved document is currently experimental.

This plugin is in early development, so expect some bugs. Please report in Github issue tracker if you had any issues with the plugin.
