Hi,

I am having a lot of troubles with unicode conversion using Python 2.7 and Pyjs. So, I am thinking about moving from Python 2 to Python 3. Unicode is the default encoding in Python 3 and Javascript. So I am hoping that the unicode conversion is not necessary in Pyhon 3 and Pyjs usage.

Does Pyjs support Python 3? Is there anyone who tried this?

Thanks in advance

Adrien

we have the same concern for our project Salut à Toi. One of our dev

This is the sad truth... or someone here has better news?

Cheers,

I have moved all of my PyJS development over to Brython, which is only on python 3 :-), so that may be a way forward.

Also, I notice that the message you're citing calls out Twisted... which is approaching half of its lines covered on py3: https://twitter.com/hawkieowl/status/603041912770015234

Is it possible to build a standalone desktop application in Brython? I need a cross-platfrom solution for both web and desktop environments.

Since it's just a web page, you could probably distribute it with something like http://code.tutsplus.com/tutorials/introduction-to-html5-desktop-apps-with-node-webkit--net-36296 :)

Thanks for letting me know about Brython. I studied it for a while, and I had impression that it didn't provide Model-View-Controller structure because it's main goal is to replace Javascript with Python (Please correct me if I am wrong). I think that simply replacing javascript syntax is not really (and not fully) Pythonic.

Below is an example from Brython site. As you can see, the button id is inside html code, and its event controller is in Brython code. It make really difficult to read, and it is one of the reason why javascript is horrible in readability.

<html>

<head>

<script src="/brython.js"></script>

</head>

<body onload="brython()">

<script type="text/python">

from browser import document, alert

def echo(ev):

    alert(document["zone"].value)

document['mybutton'].bind('click',echo)

</script>

<input id="zone"><button id="mybutton">click !</button>

</body>

</html>

I think that not only javascript but also html code all together should be replaced with Python to be fully pythonic. I am really happy with using Pyjs because I am writing quite a large web applications without html code, and Pyjs's Model-View-Controller structure really helps me write clean and reusable code. Brython might be developing further toward Model-View-Controller structure in the future, but I am worrying that rewritting my code to Brython right now is quite a huge job and the end results become worse in readability and reusability.
