Description: ==================
        Sphinx Paramlinks
        ==================
        
        A `Sphinx <http://sphinx.pocoo.org/>`_ extension which allows ``:param:``
        directives within Python documentation to be linkable.
        
        This is an experimental, possibly-not-useful extension that's used by the
        `SQLAlchemy <http://www.sqlalchemy.org>`_ project and related projects.
        
        Configuration
        =============
        
        Just turn it on in ``conf.py``::
        
            extensions = [
                        'sphinx_paramlinks',
        
                        # your other sphinx extensions
                        # ...
                    ]
        
        Stylesheet
        ==========
        
        The paragraph link involves a short stylesheet, to allow the links to
        be visible when hovered.  This sheet is called
        ``sphinx_paramlinks.css`` and the plugin will copy it to the ``_static``
        directory of the output automatically.   The stylesheet is added to the
        ``css_files`` list present in the template namespace for Sphinx via the
        ``Sphinx.add_stylesheet()`` hook.
        
        Features
        ========
        
        * ``:param:`` directives within Sphinx function/method descriptions
          will be given a paragraph link so that they can be linked
          to externally.
        
        * A new text role ``:paramref:`` is added, which works like ``:meth:``,
          ``:func:``, etc.  Just append the parameter name as an additional token::
        
             :paramref:`.EnvironmentContext.configure.transactional_ddl`
        
          The directive makes use of the existing Python role to do the method/function
          lookup, using the ``:obj:`` role; then the parameter name is applied separately
          to produce the final reference link.
        
        
        Compatibility
        =============
        
        Python Compatibility
        --------------------
        
        The extension was developed on Python 2.7, but is compatible with at least
        Python 3.3 as well.  It contains one ``u''`` literal - these are supported again
        as of Python 3.3.
        
        Sphinx Compatibility
        --------------------
        
        I've tried *very* hard to make as few assumptions as possible about Sphinx
        and to use only very simple public APIs, so that architectural changes in future
        Sphinx versions won't break this plugin.   To come up with this plugin I
        spent many hours with Sphinx source and tried many different approaches to
        various elements of functionality; hopefully what's here is as simple and
        stable as possible based on the current extension capabilities of Sphinx.
        
        One element that involves using a bit of internals is the usage of the
        ``sphinx.domains.python.PyXRefRole`` class, which is currently the
        Sphinx class that defines roles for things like ``:meth:``,
        ``:func:``, etc.  The object is used as-is in order to define the
        ``:paramref:`` role; the product of this role is later transformed
        using standard hooks.
        
        Another assumption is that in order to locate the RST nodes Sphinx
        creates for the ``:param:`` tags, we look at ``nodes.strong``,
        assuming that this is the type of node currently used to render
        ``:param:`` within RST.  If this changes, or needs to be expanded to
        support other domains, this traversal can be opened up as needed.
        This part was difficult as Sphinx really doesn't provide any hooks
        into how the "Info Field List" aspect of domains is handled.
        
        Overall, the approach here is to apply extra information to constructs
        going into the Sphinx system, then do some transformations as the data
        comes back out.   This relies on as little of how Sphinx does its
        thing as possible, rather than going with custom domains and heavy use
        of injected APIs which may change in future releases.
        
        Future Enhancements / Missing Features
        ======================================
        
        The extension currently does only ``:param:`` elements within the
        Python role, but could also be expanded to support other Python role
        elements such as ``:returns:``, ``:raises:``, etc., and perhaps also
        could be made to support similar features in other roles.
        
        Another area that's not addressed at all is search.   While the params here
        are linked, these objects are currently not part of the search index Sphinx
        creates in any usable way.   I don't know what would be involved to make that
        work.
