After installing the current Python CVS, I tried to do
>>> from onlinehelp import help
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/local/lib/python2.0/onlinehelp.py", line 323, in ?
help=Help(sys.stdout,24)
File "/usr/local/lib/python2.0/onlinehelp.py", line 216, in __init__
raise EnvironmentError, error
EnvironmentError: Cannot find documentation directory /usr/local/bin/doc.
Set the PYTHONDOCS environment variable to point to a "doc" directory.
It should have a subdirectory "Lib" with a file named "index.html".
I was mainly interested in seeing the doc string retriever in real
life. To do so, I'm in the process of obtaining a set of html files
(hopefully typing make in the Doc directory will give me those).
Still, I think that module should work without HTML help installed,
and only fail if somebody tries to access the documentation. Or, there
should be a function doc() in addition to help() for retrieving and
printing doc strings.
I'd actually prefer the second option:
>>> doc(xml)
Core XML support for Python.
This package contains three sub-packages:
dom -- The W3C Document Object Model. This supports DOM Level 1 +
Namespaces.
parser -- Python wrappers for XML parsers (currently only supports Expat).
sax -- The Simple API for XML, developed by XML-Dev, led by David
Megginson and ported to Python by Lars Marius Garshol. This
supports the SAX 2 API.
should work even without any documentation installed. In any case, I
think this (or the help function) should be builtin.

Martin
