oneFace is a Python library for automatically generating multiple interfaces(CLI, GUI, WebGUI) from a callable Python object or a command line program.

oneFace is an easy way to create interfaces.

In Python, just decorate your function and mark the type and range of the arguments:

from oneface import one, Val

@one
def bmi(name: str,
        height: Val[float, [100, 250]] = 160,
        weight: Val[float, [0, 300]] = 50.0):
    BMI = weight / (height / 100) ** 2
    print(f"Hi {name}. Your BMI is: {BMI}")
    return BMI


# run cli
bmi.cli()
# or run qt_gui
bmi.qt_gui()
# or run dash web app
bmi.dash_app()

These code will generate the following interfaces:

CLI	Qt	Dash

Wrap command line program

Or you can wrap a command line using a config file:

# add.yaml
# This is a demo app, use for add two numbers.
name: add

# mark the arguments in command with: {}
command: python {verbose} -c 'print({a} + {b})'

inputs:
  # describe the type and range of your arguments
  verbose:
    type: bool
    default: False
    true_insert: "-v"  # insert '-v' to the command when the value is true
    false_insert: ""
  a:
    type: float
    range: [-100.0, 100.0]
    default: 0.0
  b:
    type: float
    range: [-100.0, 100.0]
    default: 10.0

Lanuch the app with:

$ python -m oneface.wrap_cli run add.yaml dash_app  # run Dash app, or:
$ python -m oneface.wrap_cli run add.yaml qt_gui  # run Qt GUI app

Features

• Generate CLI, Qt GUI, Dash Web app from a python function or a command line.
• Automatically check the type and range of input parameters and pretty print them.
• Easy extension of parameter types and GUI widgets.
• Support for embedding the generated interface into a parent application.

Detail usage see the documentation.

Installation

To install oneFace with complete dependency:

$ pip install oneface[all]

Or install with just qt or dash dependency:

$ pip install oneface[qt]  # qt
$ pip install oneface[dash]  # dash
