Struct PythonCompletionProvider 

pub struct PythonCompletionProvider;

Python-specific completion provider (fallback)

This is a fallback provider for Python code when external LSP (pylsp) is unavailable.

Behavior

Generates Python-specific completions including:

• Python keywords (def, class, if, for, while, try, except, etc.)
• Python-specific snippets (function definitions, class definitions, etc.)
• Python decorators (@property, @staticmethod, @classmethod, etc.)
• Python type hints (List, Dict, Set, Optional, Union, etc.)
• Python context managers (open, lock, transaction, etc.)
• Available symbols from code context

When Used

• External LSP (pylsp) is not configured
• pylsp is not installed or fails to start
• pylsp times out or becomes unresponsive

Limitations

• No type inference or semantic analysis
• Cannot resolve imports or dependencies
• No project-aware completions
• Cannot determine variable scope or type information
• Limited to hardcoded keywords and patterns

Recommended Configuration

For production-quality Python completions, install and configure pylsp:

pip install python-lsp-server

Then configure it in lsp-servers.yaml:

servers:
  python:
    - language: python
      executable: pylsp
      enabled: true
