Hi,
I agree with Nolia - I like your add-ons too. You certainly have good
and creative ideas.
Thanks.

The problem is that NVDA itself includes some (but not all) modules in
the xml package. This means that NVDA's copy of the xml package will
take precedence. You should be able to do something like this before
what you're already doing:
import xml
xml.__path__.append(os.path.join(PLUGIN_DIR, "lib", "xml"))
This makes Python search your copy of the xml package when looking for
modules in the xml package.

Hi all,
I'm working on a new addon that will download youtube videos and save
them into chosen video or audio format automatically with a single
keystroke. It works as follows: You open a URL with a video, press
nvda+shift+y and ther URL will be autodetected and the download begins
automatically, so you can download while listening video with no need
to paste url or switch to another window.
To achieve this, I'm using youtube_dl which works both as a single app
and a Python module. I don't wanna run it as an app, because it'll
pop-up command prompt while downloading, and also I'll not be able to
catch exceptions that may eventually happen, so I'm running it as a
Python module. Unfortunately, youtube_dl uses some python modules not
included with NVDA by default, so I copied manually all required
external modules from python27/lib into a lib subfolder inside the
globalPlugin's folder, and I added this subfolder to the sys.path
inside the addon's __init__.py as follows:
PLUGIN_DIR = os.path.dirname(__file__)This allowed youtube_dl to import all required modules including
sys.path.append(os.path.join(PLUGIN_DIR, "lib"))
import youtube_dl
del sys.path[-1]
urllib2, json and others, but the problem begins when it comes to
import xml.etree.ElementTree. Here's what I get when i open log viewer:
ERROR - globalPluginHandler.listPlugins (11:06:50):So, the utils.py submodule of youtube_dl cannot find xml.etree,
Error importing global plugin youtube
Traceback (most recent call last):

ImportError: No module named etree.ElementTree
although I've double checked that xml folder is copied properly with
all the subfolders.
I tried to fix this in many ways, so I really have no more ideas on
how to get all external submodules imported properly when running the
plugin.
Thanks for any help!
