#41 pluginloader and docset with Python >2.0
I have several problems with HappyDoc under Python
>2.0, that I didn't have when using Python 2.0.
On Intel-Linux machine I get the following errors:

I have found out that the pluginloader module gets a
list of *.pyc files instead of *.py files and thus the
string slicing [:-3] fails.

Under a Python installed on SUN-Solaris machines,
I get only the docset error:

I haven't been able to reproduce this problem with Python 2.1.1 (used
for development). I'm currently updating to Python 2.2 and will verify
that the problem does not occur there.
Which version of HappyDoc are
you using?

I have not seen this problem with Python 2.2 under Linux or Win32. Can you
still reproduce the problem?

I used HappyDoc_r1_6_1.tar.gz and the error is still
reproducable.
I tried to install newer versions of HappyDoc (2.0 or
2.0.1),
but they fail, because there is only a directory named
'happydoclib' and the programs seem to import it like a
module.
Is this a feature of newer versions of Python?

The problem with the setup script probably has to do with
the fact that sys.path does not include the current
directory by default. I'll work on the setup script to fix
that.
Using a directory like a module is a fairly old feature of
Python. I think it was introduced in 1.5, but I'm not sure.
If there is an __init__.py file in the directory, then when
you import the directory you get a module with the contents
of the __init__.py module. You can have other modules in
the directory, which makes for a clean way to hide code and
simplify the interface to a library without putting all of
your library in one file.

I tested to get it running by setting $PYTHONPATH to several
directories. But it didn't work.
Unfortunately there is no '__init__.py' file in
'happydoclib' itself, but only in its sub-directory
'formatter'.

The problem with the setup script probably has to do with
the fact that sys.path does not include the current
directory by default. If you grab the latest setup.py
script from CVS, you should be able to get through the
installation.

It sounds like you have a bad tarball. I just posted a new
one today that includes some other win32 fixes, so you might
want to grab that anyway.
I'll experiment with this further the next time I have a
chance to boot into windows. That might be a day or two,
though, based on how this week is shaping up. :-)

I still have not been able to reproduce this on any of the
systems at home or work. Please re-open the bug if you
continue hvaing trouble.
