Re: Plans for python support on lyx-2.2

Would anyone oppose to change the requirements for devel as stated above? python 2.7 or 3.3+ I think it's a very good idea as Python 2.7 is still default on Mac OS and perhaps also other platforms. -- Regards, Cyrille Artho - http://artho.com/ Those who will not reason, are bigots, those wh

Hi, Again - on OS X 10.7, this will not work. And I don’t think the scripts used in LyX are that complex that we cannot handle them with using the future statement; for the two first scripts I converted, the work was trivial and did not require it.  We can maybe start by not using it and discu

Mac OS 10.9 (Mavericks) has 2.7.5 installed. So we should keep 2.7.X compatibility. I think most people still use 2.7, as 3.X is relatively new (in terms of software maintenance/update cycles) and it takes considerable effort to switch a project over to 3.X. Jean-Marc Lasgouttes wrote: Le 24/

Hi all, I suggest to update the python code used by lyx to support both python 2 and python 3 with the same code. For those who (did not) read the summit notes from Guido: http://thread.gmane.org/gmane.comp.python.devel/147048 There is one point particularly that I noticed: "- The recomm
