lilliepy_import

lilliepy_import is a Python package that provides utility functions for dynamically importing modules and components. It is designed to make it easy to set a component directory and load specific functions or classes dynamically.

Features

• Dynamically set a component folder using Importer.
• Import specific functions or classes from files in the component folder with _import.
• Supports dynamic module imports with error handling.

Installation

To install the package, use pip:

pip install lilliepy_import

Usage

Setting the Component Folder

First, set the component folder where your modules are stored:

from lilliepy_import import Importer

# Set the component folder
Importer("components")

Importing a Function or Class

You can then dynamically import a specific function or class:

from lilliepy_import import _import

# Dynamically import a function or class
try:
    my_function = _import("my_module.py", "my_function")
    if my_function:
        my_function()  # Call the imported function
    else:
        print("Function not found in the module.")
except Exception as e:
    print(f"Error: {e}")

Example

Assume the following directory structure:

project/
├── components/
│   └── my_module.py
└── main.py

my_module.py:

from reactpy import component, html

@component
def my_function():
    return html.h1("yo")

main.py:

from lilliepy_import import Importer, _import

# Set the component folder
Importer("components")

# Import and call the function
func = _import("my_module.py", "my_function")
if func:
    func()

When you run main.py, the output will be:

Hello from my_function!

Error Handling

• Raises a ValueError if the component folder is not set before calling _import.
• Raises a FileNotFoundError if the specified file does not exist.
• Handles cases where the function or class is not found in the module.
