rdee-easyarg 25.1.15

rdee-series toolkits: python-easyarg

rdee-python-easyarg

• Used to run any function with generic arguments from CLI
• Support two modes: CLI app or CLI executor

Install

• pip install rdee-easyarg

Examples

CLI-app mode

• In this mode, we use a decorator to generate CLI interface automatically, mimicing typer in general

import easyarg

ea = easyarg.EasyArg()


@ea.command()
def f1(x: int, y: int):
    print(x+y)


if __name__ == "__main__":
    ea.parse()

• You can run the script directly, such as ./a.py f1 --x 1 --y 2, and get 3
• -h/--help for app level and function level are both supported

CLI-executor mode

• In this mode, we can run a function without modifying any of its code
• For instance, given the funcs.py

def add(x: int, y: int = 0) -> int:
    print(x + y)

def mul(a: float, B: float, c: float = 1.0) -> float:
    print(a * B * c)

• just run python -m easyarg funcs.py add --x 1 --y 2 to execute the function "add"
