tree-interval 0.1.32

A Python package for managing and visualizing interval tree structures

Tree Interval

A powerful Python package for managing, analyzing, and visualizing tree structures with rich interval-based node positioning

✨ Features

• 🔮 Future Class: Powerful dynamic attribute handling with context-aware error reporting and smart chain creation
• 📍 Position-Aware Nodes: Track code positions with line numbers, column offsets and intervals
• 🌲 AST Analysis: Built-in support for Python AST traversal and node location
• 🔍 Frame Analysis: Runtime code inspection with frame position tracking
• 🎨 Rich Visualization: Multiple visualization options including ASCII trees and Rich-based pretty printing
• 💾 JSON Serialization: Full support for saving and loading tree structures
• 🔎 Flexible Node Search: Parent, child and sibling search with custom predicates

🚀 Quick Start

Dynamic Attribute Handling with Future

from tree_interval import Future

class Nested:
    def __init__(self):
        self.__dict__ = {}
        
    def __getattr__(self, name):
        return Future(name, frame=1, instance=self)

# Dynamic attribute chain creation
obj = Nested()
obj.a.b.c = 42  # Creates nested structure automatically
print(obj.a.b.c)  # 42

# Smart error reporting
print(obj.x.y.z)  # Raises detailed error with context

Tree Operations

from tree_interval import Tree, Leaf, Position

# Create a basic tree
tree = Tree("Example")
root = Leaf(Position(0, 100), "Root")
child = Leaf(Position(10, 50), "Child")

tree.root = root
tree.add_leaf(child)

# Visualize the tree
tree.visualize()

📦 Installation

pip install tree-interval

🎯 Core Components

Position Types

# Basic Position
pos = Position(0, 100)

# Line-Aware Position
pos = Position(0, 100)
pos.lineno = 1
pos.end_lineno = 5

# Column-Aware Position
pos = Position(0, 100)
pos.col_offset = 4
pos.end_col_offset = 8

Tree Visualization

# Basic ASCII Tree
tree.visualize()

# Rich Pretty Printing
from tree_interval.rich_printer import RichTreePrinter
printer = RichTreePrinter()
printer.print_tree(tree)
