parameterization

What problem does it solve?

Param provides a declarative, type-safe way to define configuration for Python applications, auto-validating inputs and enabling automatic UI generation for dashboards and tools.

Core Features & Use Cases

• Parameter basics: Define parameterized classes with built-in validation and clear documentation.
• Advanced parameter types: Support for dates, files, ranges, colors, and complex nested structures.
• Dynamic dependencies & watchers: Automatic recomputation and side-effect triggers when parameters change.
• Hierarchical parameterization: Compose configurations from reusable sub-parameters and objects.
• Panel integration: Auto-generated UIs from parameter definitions for quick user interfaces.
• Use cases: Building configuration managers, data-processing pipelines, scientific simulations, and interactive dashboards.

Quick Start

Create a simple Param.Parameterized subclass, instantiate it, and render a Panel UI automatically from its parameters.
