z3c.recipe.sphinxdoc
====================

Introduction
------------

This buildout recipe aids in the generation of documentation for the
zope.org website from restructured text files located in a package.
It uses Sphinx to build static html files which can stand alone as a
very nice looking website.

Usage Instructions
------------------

Suppose you have a package called ``z3c.form``.  In the ``setup.py``
for ``z3c.form`` it is recommended that you add a ``docs`` section
to the extras_require argument.  It should look something like this::

    extras_require = dict(
        docs = ['Sphinx',
                'z3c.recipe.sphinxdoc']
        )

Then in the buildout.cfg file for your package, add a ``docs`` section
that looks like this::

  [docs]
  recipe = z3c.recipe.sphinxdoc
  eggs = z3c.form [docs]

Be sure to include it in the parts, as in::

  [buildout]
  develop = .
  parts = docs

Now you can rerun buildout.  The recipe will have created an
executable script in the bin directory called ``docs``.

This script will run the Sphinx documentation generation tool on your
source code.  By default, it expects there to be an ``index.txt`` file
in the source code.  In this case, ``index.txt`` would have to be in
``src/z3c/form/index.txt``.  This file can be a standard restructured
text file, and can use all the sphinx goodies.  For example, your
``index.txt`` might look like this::

  Welcome to z3c.form's documentation!
  ====================================

  Contents:

  .. toctree::
     :maxdepth: 2

     README

  Indices and tables
  ==================

  * :ref:`genindex`
  * :ref:`modindex`
  * :ref:`search`

You should read the documentation for Sphinx to learn more about it.
It is available here: http://sphinx.pocoo.org/

Now you should be able to run the ``docs`` script::

  $ ./bin/docs

This generates all the documentation for you and placed it in the
parts directory.  You can then open it up in firefox and take a look::

  $ firefox parts/docs/z3c.form/build/index.html

Additional Options
------------------

By default, this recipe generates documentation that looks like the
new zope website ( http://new.zope.org ) by ovveriding the default
layout template and css file used by sphinx.  You can modify this
behavior with options in your buildout configuration.

Give me back Sphinx's default look!
...................................

To get back the default look of sphinx, you could use a configuration
like this::

  [docs]
  recipe = z3c.recipe.sphinxdoc
  eggs = z3c.form [docs]
  default.css =
  layout.html =

I want my own custom look
.........................

You can also specify your own layout template and css like so::

  [docs]
  recipe = z3c.recipe.sphinxdoc
  eggs = z3c.form [docs]
  default.css = http://my.own.website.com/mystyles/some-theme.css
  layout.html = /path/to/layout.html

Note that you can either specify a path on the local file system or a
url to an external css file.
