🎯 Why RenderSchema?

Developers love diagrams but hate making them. RenderSchema solves this by automatically generating clean, professional diagrams from your Python code. No more manual diagramming tools or outdated documentation!

📦 Installation

# Basic installation
pip install renderschema

# With PNG/PDF export support
pip install renderschema[image]

# Full installation (all features)
pip install renderschema[all]

🚀 Quick Start

Generate a UML Diagram

from renderschema import diagram

class Person:
    def __init__(self, name: str, age: int):
        self.name = name
        self.age = age
    
    def greet(self) -> str:
        return f"Hello, I'm {self.name}!"

# Generate diagram - it's that simple!
diagram(Person).export("person.svg")

Create a Flowchart

from renderschema import diagram

def calculate_discount(price: float, customer_type: str) -> float:
    if customer_type == "vip":
        return price * 0.8
    elif customer_type == "premium":
        return price * 0.9
    else:
        return price

diagram(calculate_discount, diagram_type="flowchart").export("discount.svg")

Visualize Class Relationships

from renderschema import diagram

class Animal:
    pass

class Dog(Animal):
    def bark(self): pass

class Cat(Animal):
    def meow(self): pass

diagram([Animal, Dog, Cat], diagram_type="class").export("animals.svg")

🎨 Themes

RenderSchema supports both light and dark themes:

# Light theme (default)
diagram(MyClass, theme="light").export("light.svg")

# Dark theme - perfect for dark mode documentation
diagram(MyClass, theme="dark").export("dark.svg")

📤 Export Formats

Export to multiple formats based on your needs:

# SVG - vector graphics, perfect for web and scaling
diagram(MyClass).export("output.svg")

# PNG - raster image (requires cairosvg)
diagram(MyClass).export("output.png")

# PDF - for print documentation (requires cairosvg)
diagram(MyClass).export("output.pdf")

# Interactive HTML - zoomable and pannable
diagram(MyClass).export("output.html")

💡 Advanced Usage

Get Diagrams as Strings

# Get SVG markup as string
svg_content = diagram(MyClass).to_svg()

# Get interactive HTML as string
html_content = diagram(MyClass).to_html(interactive=True)

Analyze Before Generating

generator = diagram(MyClass)
data = generator.analyze()  # Get structured data about the class
svg = generator.generate()   # Generate the diagram

Custom Options

# Customize diagram generation
diagram(
    MyClass,
    theme="dark",
    color_scheme="tailwind"
).export("custom.svg")
