Powerful Features for Modern Python Development

Everything you need to write better Python code, faster and with more confidence.

🧠
textDocument/completion

IntelliSense Completions

Full LSP completion support with type inference. Get context-aware suggestions with function signatures, parameter hints, and docstringsβ€”exactly like VS Code.

⚑
Document/publishDiagnostics

Instant Type Checking

Pyright-powered static analysis catches type errors, undefined variables, and import issues before runtime. Zero-config diagnostics for the entire workspace.

🎯
textDocument/definition

Go-to-Definition

Jump to function, class, or variable definitions across files, packages, and virtual environments. Works with stdlib, third-party libs, and your code.

πŸ”
textDocument/references

Find All References

Locate every usage of a symbol across your entire codebase in milliseconds. Perfect for refactoring or understanding data flow in complex projects.

πŸ’‘
textDocument/hover

Hover Type Info

Inspect type annotations, function signatures, and docstrings on-demand. See inferred types, parameter info, and return types without leaving your flow.

πŸ”„
textDocument/rename

Safe Symbol Renaming

Rename variables, functions, or classes across multiple files with guaranteed correctness. LSP ensures all references are updated atomically.

✨
textDocument/formatting

Auto-Format & Fix

Format Python code with Black/autopep8 integration. Apply quick fixes for imports, type hints, and common issues with a single command.

πŸ—‚οΈ
