Cheetah with Python3

[Alan Harris-Reid]

I am a newbie to Python and I have started playing-around with 3.1.  
However, I realise that most of the 3rd-party add-ons are still based on
version 2.5 or 2.6.  Does anyone know what plans there are to port
Cheetah so it can run under 3.x?

TIA
Alan

Given the number of issues with Python 3.0 I hadn't considered it to be
honest. I'm curious as to whether the Python team has corrected a number
of the performance deficiencies in 3.1?

That said, You're the first person to register any sort of demand for
Cheetah on Python 3.xx that I've heard of (patches welcome!), but at
this point there's not a lot of "production" usage that warrants
updating Cheetah for 3.xx.

Definitely!  At least, so I hear; pressures from my new job and other
stuff have kept me somewhat out of the loop lately.

I know that there's an experimental branch of Django for 3.x and I think
it would be worthwhile to at least try 2to3 on Cheetah to see what
happens.  If nothing else, the core developers would appreciate knowing
what roadblocks you hit, because they really want 3rd party libraries to
start moving toward 3.x.

Thanks for the reply Tyler -  I suppose it's a case of waiting until a 'critical mass' of Python developers move-over to 3.x before the 3rd-party developers have an incentive to update their products.  (What comes 1st, the chicken or the egg?)

Alan

I went ahead and installed 3.1 on my laptop the other day after the beginning
of this thread, if that's any consolation ;)

Anyways, the vast majority of Cheetah was written by Tavis for an older version
of Cheetah (just officially killed "support" for 2.3), I've just been keeping
the place clean since. From my initial look, it's not going to be difficult to
run on Python 3.xx, just tedious.

Ideally I'd like to keep the same tree for Python 2.4-3.1 if possible. If
you've got cycles to spare, fork git://github.com/rtyler/cheetah.git
(http://github.com/rtyler/cheetah) and start poking about with 2to3.


I'd like to support Python 3, if for nothing other than bragging rights, but I
just don't have a lot of extra bandwidth right now

Unfortunately my knowledge of Python isn't good enough yet to go 'poking around' with anything!  I am starting to get going with 3.1, and I know I will need some sort of templating soon for the work I intend to do, but AFAIK there's none that work with 3.x.  From from the templating add-ons I've seen of it so far, Cheetah is one of the most programmer-friendly, so it will be interesting to see if/when it is ported-over.

Of course I could have started with 2.6 (and maybe should have), but that seems a backward step somehow.

Regards,
Alan
