Simple UI, autogenerated from your classes.

mutaprops

https://img.shields.io/pypi/v/mutaprops.svg https://img.shields.io/travis/JNevrly/mutaprops.svg Documentation Status Updates

Mutated Properties - a simple HTML5 property-configuration UI, autogenerated from your classes.

It’s great if you need a quick’n’dirty UI with minimal effort and without changing much of the existing codebase. Mutaprops also thrive on headless systems when usual UI solutions like tkinter doesn’t make sense.

However, the customization possibilities are limited, so if you are looking for some framework for building a full-fledged attractive GUI, better look elsewhere.

Features

  • Generate a self-documented web UI directly from your objects with simple decorators
  • UI state automatically updated with object state changes (through websockets)
  • Supports multiple UI sessions on the same object, synchronized through websockets
  • Supports clustering of UI’s from multiple machines
  • UI look and feel can be customized with your own stylesheet
  • Add any widget you like with direct HTML support
  • HTML5 log console capturing all your Python logging
  • Asyncio support (and also a requirement ;))

The simplest example

Imagine a normal Python class:

class Hoovercraft:

    MAX_EELS = 40

    def __init__(self, number_of_eels=20, speed=0, direction='North'):
        self._eel_count = number_of_eels
        self._speed = speed
        self._direction = direction
        self._engine_running = False
        self._steering_locked = True

    @property
    def eels(self):
        return self._eel_count

    @eels.setter
    def eels(self, value):
        self._eel_count = value
        if self._eel_count >= self.MAX_EELS:
            logger.warning("The hoovercraft is full of eels!")

    def drop_all_eels(self):
        self.eels = 0
        logger.info("Eels are goooone!")

Now, to turn this into an UI, one just has to decorate it like this:

from mutaprops import *

@mutaprop_class("Hoovercraft UI")
class Hoovercraft:

    MAX_EELS = 40

    def __init__(self, number_of_eels=20, speed=0, direction='North'):
        self._eel_count = number_of_eels
        self._speed = speed
        self._direction = direction
        self._engine_running = False
        self._steering_locked = True

    @mutaproperty("Number of eels", MutaTypes.INT, min_val=0,
                  max_val=MAX_EELS)
    def eels(self):
        return self._eel_count

    @eels.setter
    def eels(self, value):
        self._eel_count = value
        if self._eel_count >= self.MAX_EELS:
            logger.warning("The hoovercraft is full of eels!")

    @mutaprop_action("Drop all eels!")
    def drop_all_eels(self):
        self.eels = 0
        logger.info("Eels are goooone!")

And then run it like this:

if __name__ == '__main__':

    test = Hoovercraft()
    test.muta_init("Hoovercraft instance #1")
    man = HttpMutaManager("Hoovercraft manager", proxy_log=logger)
    man.add_object(test)
    man.run(port=9000)

Et voila, here’s the UI:

Other examples

The examples/ folder contains several other examples:

  • simple_example.py is the extension of the example above, including more data types and also shows how to work with docstrings and mutasources
  • advanced_example.py demonstrates grouping of parameters, style customizations, raw HTML features and asyncio integration.
