Go PySide2 🚀

[lipkau]

Expected Behavior

I bid to make a2 compatible with Python 3.5 or greater

Current Behavior

a2 only works with Python 3.0 to 3.4

Possible Solution

• Update to PySide 2
• migrte to Tkinter
• migrate to PyGObject

a2 was never written with Python 2.x! There was a time when it ran but I doubt it actually does now (I make vast use of the items() dictionary iterator which is named iteritems() in 2.x.)

What is Tkinter? And what's PyGObject? Why would that be an option?

better? ;-)

they are GUI libraries.

I believe pip install six would make .items() work in 2.7 --> but I did not test it

Do you have any idea how much Qt code is in this project? I feel almost insulted for the suggestion to consider another ui lib! It'll be PySide2 and nothing else!

[lipkau]

so deciding how to solve this was easy.
I am reading about PySide 2. I am very curiouse about how much of it is already working.

at least Qt got involved in the porting this year. things are going much faster

Yea we are working with Qt5 here already and the guys are building PySide2 freshly to use it. Seems it's actually the current official way to get it.

Maybe I can get a build and try a2 on it. Might even be, that there is no change needed to make it run.

So the options are:

• set up to build PySide2 ourselves
• go and fix the bug that keeps PySide2 building on 3.4
• go and fix the bug that keeps PySide building on 3.5 (I actually created the report in Sep 2015! 😄)
• just keep using 3.4 + PySide and wait for PySide2 to work on 3.5

Currently I don't see any benefit from having 3.5 and no problems using 3.4. "It's not the latest" does not seem crucial at the time.

• wait for someone else to built binaries for Python 3.6 for PySide2 on Qt5.9:

this fredrikaverpil/pyside2-wheels#69 is also crucial!

Alright! I created a branch to test all this, wrote a converter script and it finally popped up already 😃
There are some things breaking still but its not far I guess.
