Subject: [Python-porting] "compiler" module in Python3k
Message-ID: <AANLkTimeDqHVmxxuCqHJeZ1jbt2zeGQq=a5YbuBXQSSj@mail.gmail.com>
Hello everyone!
I am currently working on porting a library over to Py3k and I am required
to replace the compiler module as it does not exist in 3.1. I tried
replacing the compiler module with the ast module, however that does not
meet my requirements.
I need an analogue for compiler.parse.getChildren in Python3k. Any ideas?
Thanks a lot.
Cheers!
Zubin

Subject: [Python-porting] A few observations
Message-ID: <AANLkTi=MMw5Od7bmS2iO+1QDdgYspPpdqHALLLXufAD8@mail.gmail.com>
Hello,
I have been reading a few blog posts here and there about various Arch users
having problems with the recent Py3k transition. The good news is that quite
a few of them have found a way to fix the problem and have been kind enough
to blog about this.
I was wondering if we could have an aggregation of such posts(at least
temporarily) for documenting such information so that we can help make the
Python3 transition for a certain class of users easier.

Can you please generalize a little more what this code is trying to
achieve? Most likely, the _ast module will help, perhaps also lib2to3.

Martin

In general, the answer to the question "do we have all information bits
on porting collected in one place" is "no".
>From time to time, motivated people have collected stuff in wiki pages,
but most certainly not about Arch.

ast.iter_child_nodes together with ast.iter_fields seems to do what you need.

I can't find a pattern that will match:
foo
But not
bar.foo
Any hints?

Hi Lennart,
you can use a negative lookahead:
(?!bar\.)foo

Ah, sorry for wasting peoples time by not including enough context. My bad.
I'm looking for a patterns for making a fixer, not a regexp. :-)

It's usually best to do something like "is_probably_builtin" in
lib2to3/fixer_utils.py.

Ah, thanks! That's similar to what I did already, but I missed out on
this helper (as it's slightly weirdly named), and this one catches
several cases I didn't think of.

This is normally called a negative lookbehind, though.

Both are slightly wrong: what Marc gave is a lookahead, but
ISTM he *should* have given a lookbehind :)

Which shows how often I don't use either. :-) Sorry for the

This feels like a good example of why I avoid regexps. :-)
