How to use Twill
Alexmipego
I'm trying to run some old python code that uses Twill on GAE.
Unfortunately, it doesn't seem to work. What I did was copy paste the
code and the source files for the twill library. And then I'm getting
this error:
....\src\twill\utils.py", line 275, in run_tidy
process = subprocess.Popen(_tidy_cmd, stdin=subprocess.PIPE,
AttributeError: 'module' object has no attribute 'Popen'
I'm guessing this is trying to use some function that GAE has locked
out for some reason, but, is there a working Twill version or anyone
using it that could help me out?

What are you doing exactly with twill ? If you're using in-process
intercept functionality then it might not work at GAE (I mean in the
cloud ;o), but it should work in development environment . If this is
the case I see no reason for using that feature in a production
environment .
If this is not the case , please specify what are you trying to do ;o)

I'm not familiar with that "intercept" feature, perhaps I'm using it
without knowing. Anyway, my test case is pretty simple:
import twill.commands
......
twill.commands.reset_browser()
b = twill.commands.get_browser()
b.go("http://www.google.com")
It fails on the .go(...) method, always. From the looks of the message
and knowing a bit about the "scraping" world, it seems like the code
is trying to call html tidy to do from "pretty-print" formatting. I'm
not too familiar with python either, but that subprocess.Popen looks a
lot like it's trying to run something external like if it was on a
bash or cmd.exe shell instead of calling a lib linked in the sources.
So, any clues?

Ok. I suppose that the best place to ask for this should be

Many people familiar with that module are subscribed to that list, so
you'll probably get the right answer at the right time (that's why I'm
adding it to Cc and fixing top-posting, sorry for cross-posting , it's
a noble cause ;o) .
Please read below
What version of Python are you using ? I see no reason for such
behavior if working on your local development machine | environment ,
having the right version of Py .
AFAICR, Jess Noller (talking about another subject ;o) mentioned once
@ TiP ML something related to the possibility of compiling the
interpreter without support for given modules . That's probably what's
happening in your case (but probably not ...) .

machine if I'm using the "standalone" version (read: without GAE).
