Platitudes

A zero dependency clone of Typer. The most convenient way to make CLI out of your programs.

Quick Start

from enum import Enum
from pathlib import Path
from typing import Annotated

import platitudes as pl

app = pl.Platitudes()

class Color(Enum):
    RED = 0
    GREEN = 1
    BLUE = 2

@app.command
def build_profile(
    name: Annotated[str, pl.Argument(help="User name")],  # Adding help strings
    surname: str,
    age: int,
    photo_file: Annotated[
        Path, pl.Argument(exists=True)  # Paths can be checked for existence
    ],
    favorite_color: Color = Color.RED,  # Optional enum argument with a default
):
    print(f"The user is named {name} {surname} and his favorite color is {favorite_color}")
    print(f"Age: {age}")
    print(f"Picture stored at: {photo_file}")

    assert isinstance(photo_file, Path)
    assert isinstance(favorite_color, Color)

if __name__ == "__main__":
    app()

You can then show the help for build_profile:

❯ python build_profile --help
usage: examples.py build_profile [-h] [--favorite-color {0,1,2}] name surname age photo-file

positional arguments:
  name                  User name
  surname
  age
  photo-file

options:
  -h, --help            show this help message and exit
  --favorite-color {0,1,2}

And you can run the CLI with the positional and perhaps optional arguments:

❯ python example/examples.py build_profile G Ballesteros 42 ./LICENSE
The user is named G Ballesteros and his favorite color is Color.RED
Age: 3
Picture stored at: LICENSE
