Announcing the latest version of HappyDoc, a Python documentation
extraction tool.
HappyDoc is a tool for extracting documentation from Python source
code. It differs from other such applications by the fact that it
uses the parse tree for a module to derive the information used in
its output, rather that importing the module directly. This allows
the user to generate documentation for modules which need special
context to be imported.
Version 1.4 --
- Handle Packages separately from Modules. This behavior is
optional and consists mostly of creating intermediate level
TOC pages and not showing subdirectories of a Package on the
Package's parent TOC page.
- Changed default title to include instructions about how to
change the title
- Show exceptions in plugins when there is a problem loading a
module
- Added a command line argument to support ignoring specific
subdirectories.
- Fixed problem with ignoring directories by correcting name
comparison logic.
- Change "link":URL style references which were HTML
quoted back to StructuredText so that hyperlinks can be embedded
within docstrings. (reported by Mihalopoulos Evangelos)
- Changed base class arrangement for docset so the basic interface
is documented as part of the docset base class.
- Moved some formatter functions into the docset, since they match
that API better and more properly belong there.
- Fixed bug 131751, problem with string dereference in
parseinfo.py
- Set the DOCTYPE in hdformatter_htmlfile.py. (Thanks to
Shannon -jj Behrens for the patch.)
- Fixed problem with references to extra files when using output
prefixes.
- Changed test harness to use the HappyDoc class directly instead
of calling out to a separate program.
- Output a oneliner for referenced pre-formatted documents.
- Modified parseinfo.py to improve speed
- Expanded information extracted about exceptions thrown by
functions
- Simplified the regressino test to make it faster by removing
Zope docs from the default regression test suite

Doc-string Format
How does an author write documentation so that it will be marked up
and look fancy? This is a perennial question for Python, and seems
to have introduced a roadblock into the development of more robust
and useful documentation tools. By separating the formatter classes
from the docset classes, HappyDoc allows a user to create their own
formatter to interpret comments in any way they see fit.
The default for the HTMLTableFormatter (the default formatter for
HappyDoc) is to treat __doc__ strings as StructuredText. Don't like
StructuredText? Write your own formatter that does something
different and drop it into place.
Documentation not in Doc-strings
It is not always desirable to put all documentation in __doc__
strings. Sometime, notably when working with Zope, special meaning
is attached to the presence of __doc__ strings. For this reason,
and to support existing code which might not have __doc__ strings,
HappyDoc will find and extract documentation in Python comments.
Comment documentation can contain all of the same formatting as
__doc__ strings. The preceding comment marker will be stripped off
and the lines will be assembled and treated as a block of
StructuredText.
To use this feature, it is important to place the comments
**before** the named object which they describe. In this example:
#
# Class documentation goes here
#
class ClassWithNoDocStrings:
"Using __doc__ strings overrides comment documentation."
def method1(self, params):
"This method uses a __doc__ string."
pass
#
# Method2 does not use a __doc__ string.
#
def method2(self):
pass
The output would include the __doc__ strings for the class and for
method1. It would also make it appear that method2 had a __doc__
string with the contents "Method2 does not use a __doc__ string."
