Editing Setup Toga with Spyder

= Setup Toga with Spyder =

This is an early draft not really ready for anybody but the author.

= Goal =

Get Toga running ( preferabley with editable source code ) in Spyder and IDE for Python

for Toga see: '''[https://toga.readthedocs.io/en/latest/ Toga — Toga 0.3.0.dev10 documentation ]'''

This has not been easy, still not working as of July 30: see this page history for other dates.

Unfortunately I tried so many things that some steps and details are lost in the fog of time, here
I will try to document the most important steps and results.

After a brief bout with windows, I decided to move to Ubuntu as a virtual machine under my Windows host.

Installed 18.4
then installed Anaconda ( not everything seemed to work ) which did not get me Spyder.
So I did a 

      apt get spyder3 

which seemed ok, I can now run Spyder

= Try Again Again ( Attempt 3 ) =
New virtual machine ( clone under virtual box, takes 6 minutes, try to limit install to: https://toga.readthedocs.io/en/latest/how-to/contribute.html but no virtual environment, just a clean virtual machine




= Try Again ( Attempt 2 ) =


== Set Up Git ==

New virtual machine

  git config --global user.name "russ-hensel"
  git config --global user.email xxx@comcast.net

  >>> seemed to run fine

== Upgrade Pip ==

  pip3 install --upgrade pip

  >>> Successfully installed pip-18.0

== On My Git ==

Forked then git clone and in my home directory:

   git clone https://github.com/russ-hensel/toga.git

then after much messing about got the error  ModuleNotFoundError: No module named 'travertino' so ....

   git clone  https://github.com/russ-hensel/travertino.git

== Try to Get it to Run ==

Mostly messing with path ...

mess with path until get to error: for no module gbulb so 

  pip install gbulb

seemed to work, but still get  no module gbulb .. add it to the path, explicitly but still no good
despite the install.  Google for gbulb yeilds pretty much zip ... so will remove it

<pre>
  pip uninstall gbulb

russ@ubuntu-18-base:~$   pip uninstall gbulb
Uninstalling gbulb-0.5.3:
  Would remove:
    /home/russ/anaconda3/lib/python3.6/site-packages/gbulb-0.5.3.dist-info/*
    /home/russ/anaconda3/lib/python3.6/site-packages/gbulb/*
Proceed (y/n)? y
  Successfully uninstalled gbulb-0.5.3
russ@ubuntu-18-base:~$

</pre>

so what about installing the demo:   https://toga.readthedocs.io/en/latest/how-to/get-started.html

   pip install toga-demo

runs fine, then try demo

</pre>
Installing collected packages: colosseum, toga-core, toga-gtk, toga, toga-demo
Successfully installed colosseum-0.1.6 toga-0.2.15 toga-core-0.2.15 toga-demo-0.2.15 toga-gtk-0.2.15
russ@ubuntu-18-base:~$ toga-demo
Creating symlink (/home/russ/anaconda3/lib/python3.6/site-packages/gi & /home/russ/anaconda3/lib/python3.6/site-packages/pygtkcompat) to system GTK+ libraries...



</pre>

== Read the Docs ==

https://toga.readthedocs.io/en/latest/how-to/contribute.html

= Initial Attempt =

This is incomplete, then I seemed to trash spyder, even reinstall did not fix, so starting with a clean virtual machine, and will try to document more of steops.

Also ran

*pip install toga-demo

*pip install --upgrade pip    >>>> Successfully installed pip-18.0

*toga-demo     >>> demo seemed to run

*pip install --pre toga    >>> did not get errors

*from '''[https://toga.readthedocs.io/en/latest/tutorial/tutorial-0.html Your first Toga app — Toga 0.3.0.dev10 documentation ]''' Created russ@ubuntu-18-base:~/python3/projects/toga_1.py


*python -m toga_1.py
/home/russ/anaconda3/bin/python: Error while finding module specification for 'toga_1.py' (AttributeError: module 'toga_1' has no attribute '__path__')
russ@ubuntu-18-base:~/python3/projects$ python  toga_1.py

*russ@ubuntu-18-base:~/python3/projects$ python -m toga_1.py  >>> does not work _>
/home/russ/anaconda3/bin/python: Error while finding module specification for 'toga_1.py' (AttributeError: module 'toga_1' has no attribute '__path__')

*russ@ubuntu-18-base:~/python3/projects$ python  toga_1.py  >>> does work but button is a big as window, just a detail?

*inside of spyder toga_1.py does not work, but after much messing around I found that changing the pythonpath in spyder would let it run

== Project ==

*Name:  Arduino Laser Cannon
*Status: in fairly early development, but is working. 
*Technology: Arduino 
*Author: [[russ_hensel]] ( where you can find an email address to reach me ) 
*Summary: An Arduino controls two servo motors to aim a laser pointer. A terminal program is used to control the Arduino.
*Archive for the project will be posted.  See download section below.
