Shelve Caching Decorator

Overview

This Python package provides a decorator leveraging Shelve for persistent caching. The decorator allows efficient caching of function results, improving performance by storing data persistently between program executions.

Features

• Persistent Caching: Utilizes Shelve for persistent storage of cached function results.
• Efficient Performance: Caches function results to avoid recomputation, enhancing performance for repeated calls.
• Easy Integration: Simple decorator syntax for easy integration with existing functions.
• Customizable: Easily configurable to cache functions with different argument combinations.

Installation

You can install the package using pip:

pip install shelve-caching-decorator

Usage

1. Decorator Application: Use the @persistent_cache decorator to cache function results.

   from shelvecache import persistent_cache
   
   @persistent_cache("cache.db")
   def expensive_operation(x, y):
       # Your expensive computation here
       return x * y
   
   result = expensive_operation(2, 3)  # Function result cached
   

2. Persistent Storage: The cached results are stored in the specified Shelve file ("cache.db" in the example above), ensuring persistence between program executions.
