I love this. I wish someone would do this for Ruby. Not CoffeeScript - I want to be able to write Ruby that manipulates DOM objects.
Javascript is great, but I'd rather work in Python and have it be actual Python, not an interpreter written in an interpreted language.

Not that I have anything against Brython (which imo is a cool project, although I'm not so sure if it's practical yet), but since you asked for it, here's an example where it does differ from python: x = 0 def impure(): global x x += 1 return x print(0 In python, impure() would only be evaluated once returning True, but Brython's chaining evaluates it twice, and so it returns False instead. Of course, this example is…
Nifty example, but this is why we have integration test suites. PyPy, jython, ironpython etc all had/have incompatibilities as the language evolves and as they work out the quirks in their respective runtimes. This isn't compatible with cpython (afaik, none of the other runtimes have ever been COMPLETELY compatible, but this is much further off), but hell, it's pretty awesome. As an aside, I'd shoot anyone who did th…
It is a cool project, whichever one of these python in javasript things is to become successful needs to aim for the same level of compatibility as say Jython or IronPython - yes it would take a long time, but this sort of thing is needed to be a useful implementation.

This is not a translator but an interpreter, there is no compilation. edit: except FUD, can you provide some points on which brython is failling, please ?
There's no support for metaclasses. type is missing entirely. nonlocal doesn't work. docstrings and some other double underscore names are just missing (__class__, __name__, etc.). Unicode literals don't work. dis obviously won't work since there isn't a bytecode compilation step. Scoping, like in the following code, behaves improperly: x = 1 def test(): print(x) x = 2
I love python and this is awesome. But I HATE magic global objects. 'ctx' seems to be at the heart of everything but is never explicitly passed into the scope or imported. This should really be fixed. Also "from html import *"? No no no. Never, not even once.
Also it's defined at the bottom of the script which, I admit, is a bit weird:
if hasattr(canvas,'getContext'):
ctx = canvas.getContext("2d")

Last time i checked it, it contained links to old/dead projects, which seems still the case. Anyway AFAIK there is no such a similar thing to Brython for ruby, and by that I mean a ruby implementation specifically written in JS and optimized to deal with DOM and browser environment in general (if anybody knows about something like that or is working on it please inform me). It'd be such a great thing to have!
Most of the work in the recent weeks has been improving the ruby js bridge so that calling js methods/functions from ruby is possible.

I wonder if it's worth adding some failing tests to the project about these..

Javascript is a prerequisite of the modern web. Refusing to accept that is absurd.
First of all, he was commenting about this page not displaying ANY content at all. At the very least there should be a noscript tag to tell the user to enable JS. Second, I whitelist sites for javascript. There's nothing absurd about that. Honestly, I can't believe people run any and all JS on every random page they land on.
For most sites that sounds like a good idea, but this is a Javascript project. The number of people interested in a Javscript framework that don't have Javascript enabled and are still befuddled when things don't work correctly must be vanishingly small.

JavaScript is like the electricity of the web. If you disable it, it's like walking around the real world with an "emp field", sure some things will still work, but it's kind of dumb to expect the modern technologies to work without their main food source. The technologies have evolved... Why are you trying to keep us in the stone age? Or why do you expect backwards compatibility?

Wow. I had never seen that. There are literally tears streaming down my face I was laughing so hard.
