How do you get Python documentation in Texinfo Info format?

Question

Since Python 2.6, it seems the documentation is in the new reStructuredText format, and it doesn't seem very easy to build a Texinfo Info file out of the box anymore.

I'm an Emacs addict and prefer my documentation installed in Info.

Does anyone have Python 2.6 or later docs in Texinfo format? How did you convert them? Or, is there a maintained build somewhere out there?

I know I can use w3m or haddoc to view the html docs - I really want them in Info.

I've played with Pandoc but after a few small experiments it doesn't seem to deal well with links between documents, and my larger experiment - running it across all docs cat'ed together to see what happens - is still chugging along two days since I started it!

Answer 1

Python docs are now generated using Sphynx framework. This framework does not have texinfo output format. Currently it has:

1. HTML
2. latex
3. plain text

Maybe you can get what you want using the Latex output. With the text output you will lost the cross ref.

Personnaly I prefer using pydoc when I want textual output. With Vim I have a shorcut to call pydoc and open a window with the doc for the entity under my cursor...

Answer 2

Another "workaround" is to execute pydoc as suggested by Nikokrock directly in Emacs:

(defun pydoc (&optional arg)
  (interactive)
  (when (not (stringp arg))
    (setq arg (thing-at-point 'word)))

  (setq cmd (concat "pydoc " arg))
  (ad-activate-regexp "auto-compile-yes-or-no-p-always-yes")
  (shell-command cmd)
  (setq pydoc-buf (get-buffer "*Shell Command Output*"))
  (switch-to-buffer-other-window pydoc-buf)
  (python-mode)
  (ad-deactivate-regexp "auto-compile-yes-or-no-p-always-yes")
)

Michael Ernst used to maintain Info formats of Python docs:

http://www.cs.washington.edu/homes/mernst/software/#python-info

You can try using his makefile and html2texi script to generate an updated version. Both are linked at the above URL. I'm not sure how well it works now (the last version was around 2001), but his script is well commented (grep for "python").

Answer 4

For those following this question in the hope of an answer, I found another rst2texinfo implementation which you might like to try:

Jon Waltman http://bitbucket.org/jonwaltman/sphinx-info has forked sphinx and written a texinfo builder, it can build the python documentation (I've yet done it). It seems that it will be merged soon into sphinx.

Here's the quick links for the downloads (temporary):

• http://dl.dropbox.com/u/1276730/python.texi

Steps to generate python doc in texinfo format:

Download the python source code

Download and install the sphinx-info package (in a virtualenv)

Enter in the Python/Doc directory from the python sources

Edit the Makefile, to the build target replace $(PYTHON) tools/sphinx-build.py with sphinx-build, then add this target to the makefile, pay attention, the space before echo is a TAB:

texinfo: BUILDER = texinfo
texinfo: build
    @echo
    @echo "Build finished. The Texinfo files are in _build/texinfo."
    @echo "Run \`make' in that directory to run these through makeinfo" \
          "(use \`make info' here to do that automatically)."

Edit the Python/Doc/conf.py adding:

texinfo_documents = [
    ('contents', 'python', 'Python Documentation', 'Georg Brandl',
     'Python', 'The Python Programming Language', 'Documentation tools',
     1),
]

Then run make texinfo and it should produce the texifile in the build/texinfo directory. To generate the info file run makeinfo python.texi
