Hello,
I'm the developer of PySmell ( http://github.com/orestis/pysmell ), a
static analysis/intellisense provider for Python. I am targeting
Python 2.4 code so I'm using the compiler package.
I've been toying around yesterday with the ast module in Python 2.6
and it seems much more cleaner. One thing I don't understand is how
should one handle backwards and forwards compatibility.
My impression is that the 2.6 ast package is quite different from the
2.4 compiler package, but I have not looked at it (in its 3.0 version)
yet. If the 2.4 code you are analyzing is syntactically and sematically
valid as 2.6 code, which I believe is usual, then of course there is no
problem. If it is not, then I would not be sure.
I guess that Python 2.6 can target Python 2.3-6, and with specific
compiler flags it can also target 3.0, so it seems that the correct
thing to do is to use that.
If you want to target 2.3 to 3.0, 2.6 is the only option as far as I
know. I expect you will want to run your code through 2to3 (still being
improved) and run under 3.0 to properly handle 3.0 code.
Maybe someone else can give a better answer.
