Easily turn your Python functions into GUI applications.
Perfect for internal tools, quick testing, or prototypes. FuncToGUI is cross-platform, updates in real-time, and requires no additional UI code. Implemented in 1500 lines of code!

FuncToGUI is built on top of Kivy and pyler for file handling.

Looking for a web-based version? Check out FuncToWeb - same concept, but generates web interfaces instead of desktop GUIs. Perfect for sharing tools with others or deploying to servers. Only 300 lines of Python! FuncToWeb

Normal function (no data limits):

from functogui import App

def is_even(number: int = 4) -> bool:
    return number % 2 == 0

App(is_even)

Function with UI types (limits the input data):

from functogui import App, intUi, intReturn
from typing import Annotated

def time_to_seconds(hours: Annotated[int, intUi(max_value=24)] = 1,
                    minutes: Annotated[int, intUi(max_value=59)] = 30
                    ) -> int:
    return (hours * 3600) + (minutes * 60)

App(time_to_seconds)

Function with manual execution (add a "Run" button):

from functogui import App, floatUi
from typing import Annotated

def divide(a: float = 3.0,
           b: Annotated[float, floatUi(max_value=10.0)] = 2.0
           ) -> float:
    return a / b  # 0 division is handled by the UI

App(divide, auto_update=False)

With auto_update=False, the function does not execute automatically when a parameter changes. Instead, a Run button will appear.
