Sure, lyx works with python 2.7 but it does not make any use of the new features that are present in python-2.7 but are not present in python-2.4. That is the point of forward compatible. :-) When I say that we should support python-2.7 I mean, in this context, that we should make python-2.7 the minimum supported version in order to simplify a transition to python 3 later. > > Note that even if we go python 3 we should set a minimum version, like say > > python 3.2 or even python 3.3 if we are feeling lucky. :-) > > You mean that backward compatibility issues are even within 3.x series? No. Not with that alarming tone. :-) I mean that it is easy to go from python-2.7 to python-3.3 (or 3.2) that it is to go from python-2.7 to python-3.0 or python-3.1. Take as an example the python 3.3 release: http://www.python.org/getit/releases/3.3.0/ Notice the third paragraph: "Python 3.3 includes a range of improvements of the 3.x series, as well as *easier porting* between 2.x and 3.x." In the development of python 3.3 there was a moratorium in the development of new language features in order to improve both the standard library and the porting of the code from 2.x. > > Note that personally I have no problem going the python 3 route and if we > > decide to go that way I will support it. > > I don't feel any hurry for bumping, just tried to catch you while your are > active, otherwise I'm not sure who wants to do that... > > Pavel Note that I am proposing this change after lyx-2.1 is released so in a sense this discussion is premature. Oh, BTW and then if we go with python 3.x we can call the next version lyx 3.0. :-D Or we can already adopt the firefox convention and go with lyx-3.0 for new release. :-) FWIW on a more serious note that are lots of very competent python programmers in this list so I am not worried. :-) Regards, -- José Abílio
