What it is and what it does
Nutree is a tree data structure library that lets you build and work with hierarchical node structures in Python. It supports both simple string nodes and arbitrary Python objects, with a navigation API for accessing, searching, and iterating through trees. The library handles common tree operations like pattern-based search, node filtering, and traversal in multiple ways.
The package is designed for unobtrusive integration—you can wrap existing objects as tree nodes without modification. It offers serialization to JSON (with compression support), export to graph formats like DOT and Mermaid diagrams, RDF conversion, and tree comparison with patch generation. All code is fully type-annotated and supports typed child nodes.
Use it for
- Build hierarchical file system or organizational structure representations in memory
- Search and filter tree nodes by name pattern, object reference, or ID across large hierarchies
- Serialize tree structures to JSON for storage or API transmission, with optional compression
- Generate visual diagrams of tree structures using Graphviz or Mermaid for documentation
- Compare two trees and compute structural differences or patches for version control
- Wrap arbitrary Python objects as tree nodes without modifying the original classes
