autoload_module

Get classes and functions from modules simply and efficiently. The following is a plain example.

▼ Directory

project/
 ├ main.py
 └ pipelines/
   ├ pipeline_a.py
   ├ pipeline_b.py
   └ pipeline_c.py

▼ main.py

from autoload import autoload
from functools import reduce

# Automatically import modules and return function objects
pipelines = autoload("pipelines", "function")

initial_value = 1

# Execute functions sequentially
final_result = reduce(lambda acc, func: func(acc), pipelines, initial_value)

Install

pip install autoload-module

Quick Start

There are only 2 steps. Imagine the following directory structure.

project/
 ├ main.py
 └ functions.py

1. Set @loadable to the class or function you want to import

# functions.py

from autoload import loadable


@loadable
def increment(number: int) -> int:
    return number + 1


@loadable
def decrement(number: int) -> int:
    return number - 1

2. Set package or module name to autoload

# main.py

from autoload import autoload


def main() -> None:
    functions = autoload("pipelines", "function")
    # If you want to get class
    # pipelines = autoload("pipelines", "class")

    # call increment function
    print(functions[0](1))
    # => 2

    # call decrement function
    print(functions[1](1))
    # => 0


if __name__ == "__main__":
    main()

FAQ

Can I import classes?

Set "class" to autoload .

▼ Directory

project/
 ├ main.py
 └ pipelines.py

▼ Code

# pipelines.py

from autoload import loadable


@loadable
class PipelineA:
    pass


@loadable
class PipelineB:
    pass


# main.py
from autoload import autoload

classes = autoload("pipelines", "class")

Can nested packages be loaded?

Set "recursive=True" to autoload .

▼ Directory

project/
 ├ main.py
 └ main_package/
   ├ module_a.py
   └ sub_package/
     ├ module_b.py
     └ module_c.py

▼ Code

# module_a.py
@loadable
def module_a_function() -> None:
    pass


# module_b.py
@loadable
def module_b_function() -> None:
    pass


# module_c.py
@loadable
def module_c_function() -> None:
    pass


# main.py
# only import module_a_function
functions = autoload("main_package", "function")

# import not only module_a_function but also module_b_function and module_c_function
functions = autoload("main_package", "function", recursive=True)

Can the order of loading be controlled?

Set order to @loadable .

@loadable(order=3)
def function_3() -> None:
    pass


@loadable(order=1)
def function_1() -> None:
    pass


@loadable(order=2)
def function_2() -> None:
    pass


# main.py
# The order of `functions` is function_1, function_2 and function_3.
functions = autoload("package", "function")

Can relative path be specified?

Set base to autoload .

functions = autoload("..module_a", "function", base="main_package.sub_package")
