[SciPy-dev] ndimage - docfiller and output_type
Thu Oct 29 10:27:57 CDT 2009
I now have a pretty complete implementation.
- backwards compatible (see olddefault)
- new default way with only one word of "boilerplate" (see newdefault)
- pdf method descriptions in extradoc ends up in the right place (see wald)
- ability to keep defaults for most elements while adding new sections etc
where wanted (see maxwell)
- rv_continuous can now have a useful docstring for itself, to show how to

Will do. Not too much boilerplate anyway. For the common case of a small
class that has only a couple of lines in `extradoc` that describe the
distname.pdf, the number of lines per class is pretty much unchanged. For an
example, see `wald`. Both current trunk and the new version are 18 lines.

done, works with no docstring at all, or a one-liner

numpy.random has already a lot more descriptions for the

intersphinx is enabled but doesn't work (i think). Pauli, can you clarify?

I was not paying attention there. Assigning to __class__.__doc__ only works
for old-style classes. rv_generic inherits from object, so it does not work
then. If this is important to you to fix help() you can always convert to
old-style classes. I had a quick look, and I don't think any of the
old-style / new-style differences matter for stats.distributions.

add that to `_doc_allmethods` and `_doc_afterpdf`. That's it for all classes
that did not write a custom Methods section. For the classes with custom
Methods, you would add "%(xxx)s" in there.
If you edit an existing method, you do not have to do anything.

sure, will do

makes sense, but you do not want them to show up in the instance docstring
right? maybe only in the rv_continuous and rv_discrete docstrings?

dist * 6 methods = many hundreds of pages.

I like the numpy.random pages, for example
Maybe one or two paragraphs more, that should be enough for pretty much any
distribution function, or not?
No idea about a page limit, but if you plan on writing more than a page and
a half per distribution, you have enough material for a book.....
