Guide: Kivy and Python Tools for Visual Studio

[Cam Jackson]

Hi everyone,

I posted here a while ago looking for help with Kivy and PyDev, and ended up writing my own guide on how to do it. There have since been some people requesting a similar guide for Python Tools for Visual Studio, so I've written one up for that too. So PTVS users, go here: http://www.ocularsoftware.com/2013/11/how-to-use-python-tools-for-visual-studio-to-develop-and-run-kivy-applications/.

Hope that helps someone :)

Thanks Cam! Your Pydev post helped me a lot ;-)

It seems like there is a need for IDE setup guides. I've added that to my "todo" list.

Also added a post for adding kv syntax highlighting for pycharm.

Your posts really helped with Eclipse, so thanks again. Eclipse is probably still my first choice... although PyCharm is really sexy...? ;-)

Cheers

@Zencode maybe we should consolidate the info in one place. wiki sounds like a good place to start this https://github.com/kivy/kivy/wiki/Setting-up-kivy-with-various-popular-IDE

@qua-non: Yup, agreed. I though to describe the core principles there (environment variables, venv vs. installed python) together with a generic "setup your interpreter" process, then link to IDE specific setup's. Including them all might be too much?

Feel free to adjust the information , I only added the links as stubs. Would be great if you could improve the content.

I agree that we should have sub sections like setting up environment variables, syntax highliting...etc.

Apologies to those looking for it. I do intend to rehost that page somewhere new, but for now, the wayback machine thankfully has a copy:

Hi

I am new to Livy and quite new to Python. I am trying to make a very simple Kivy application run under PTVS 2.1.  I have copied the 'simple paint' example from the Livy tutorial and added the environment settings described by Cam's blog post.  Here is the code:

#!/usr/bin/env python

import os

os.environ['GST_PLUGIN_PATH'] = 'C:\Kivy-1.8.0-py3.3-win32\gstreamer\lib\gstreamer-1.0'

os.environ['GST_REGISTRY'] = 'C:\Kivy-1.8.0-py3.3-win32\gstreamer\registry.bin'

os.environ['PATH'] = 'C:\Kivy-1.8.0-py3.3-win32\;C:\Kivy-1.8.0-py3.3-win32\Python33;C:\Kivy-1.8.0-py3.3-win32\tools;C:\Kivy-1.8.0-py3.3-win32\Python33\Scripts;C:\Kivy-1.8.0-py3.3-win32\gstreamer\bin;C:\Kivy-1.8.0-py3.3-win32\MinGW\bin;C:\ProgramData\Oracle\Java\;%PATH%'

from kivy.app import App

from kivy.uix.floatlayout import FloatLayout

from kivy.factory import Factory

from kivy.properties import ObjectProperty

from kivy.uix.popup import Popup

from kivy.app import App

from kivy.uix.widget import Widget

from kivy.graphics import Color, Ellipse

class MyPaintWidget(Widget):

    def on_touch_down(self, touch):

        with self.canvas:

            Color(1, 1, 0)

            d = 30.

            Ellipse(pos=(touch.x - d / 2, touch.y - d / 2), size=(d, d))

class MyPaintApp(App):

    def build(self):

        return MyPaintWidget()

if __name__ == '__main__':

    MyPaintApp().run()

when I run it under PTVS I get the following error:

File "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\Python Tools for Visual Studio\2.1\visualstudio_py_util.py", line 82, in exec_code

    exec(code_obj, global_variables)

  File "C:\Users\daldrich\Work\Kivy\module1.py", line 9, in <module>

    from kivy.uix.floatlayout import FloatLayout

ImportError: No module named 'kivy'

Press any key to continue 

I have set set up the kivy environment for PTVS as described in the blog post.

What setting am I likely to have done wrong that would give the error "No module named 'kivy'" ?

Best regards

David

I just noticed that kivy.bat sets:

PYTHONPATH:

C:\Kivy-1.8.0-py3.3-win32\kivy;

So do I need to add:

os.environ['PYTHONPATH'] = r"C:\Kivy-1.8.0-py3.3-win32\Kivy"

to my module?

(sorry about the typos in my previous email).

Best regards

Hi

I'm still struggling to make PTVS work with Kivy. As I wrote above, I was getting error:

ImportError: No module named 'kivy'

There seems to me to be two ways of solving this:

1) Set PYTHONPATH:

PYTHONPATH=C:\Kivy-1.8.0-py3.3-win32\kivy;

However, that didn't work for me.

2) Set Properties > Debug > Search Path to:

C:\Kivy-1.8.0-py3.3-win32\Kivy

That did work but I then get a different error:

No module named 'Image'

at line 10 of img_pil.py

Please can anyone advise me how to fix these problems?

Best regards

David

Hi, I have exactly the same problem.

Setting the debug search path should not be necessary. Setting up the PYTHONPATH variables should be enough.  Start with the most basic app that just displays a  label. Then take it from there. Does that work?

Cheers

Hi

I asked about using PYTHONPATH on the PTVS forum:

http://pytools.codeplex.com/discussions/578130

The answer was:

See this page for an explanation of why we block the value of PYTHONPATH and how to use Search Paths through Solution Explorer. 

So, it seems, that the correct way to use Kivy with PTVS is to use search paths, not PYTHONPATH.  A search path worked for me.  Perhaps this info could be added to the PTVS Guide for Kivy?

Hello Everyone

How can I make the KV file be read by Pycharm in a smart way.

It already is working, but doesn't allow me to do smart folding/unfolding and see the different identations and commands in colors, as do the py file.

Thanks in advance

Happy Coding
