It was my understanding that you should be able to use lib/pythonXXX/lib2to3 from any recent python distribution (2.x or 3.x) interchangeably. A quick glance at a diff between lib2to3 on 2.7 and 3.2 seems to confirm that. Corrections welcome. I doubt the few ports that explicitly rely on 2to3 (sorry, I have not fully audited the ports to figure out which ports do, but I expect it's a small number, possibly 0 [1]) care whether XXX is 2.7 or 3.2. If my assertion is correct, the proposed 2to3 port would just contain one file: % cat /usr/local/bin/2to3 #!/usr/bin/env python import sys from lib2to3.main import main sys.exit(main("lib2to3.fixes")) (where this is the only difference between old and new: --- 2to3.orig 2012-06-05 12:44:17.000000000 -0600 +++ 2to3 2012-06-05 12:44:30.000000000 -0600 @@ -1,4 +1,4 @@ -#!/usr/local/bin/python2.7 +#!/usr/bin/env python import sys from lib2to3.main import main And the 2to3 port would have a (run) dependency on python (any installed version will do). [1] py-sqlalchemy is one, sort of. It has a script that imports lib2to3 directly instead of invoking 2to3. _______________________________________________ freebsd-python@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-python To unsubscribe, send any mail to "freebsd-python-unsubscr...@freebsd.org"
