What is pagination?
---------------------
This module helps dividing large lists of items into pages. The user is
shown one page at a time and
can navigate to other pages. Imagine you are offering a company phonebook
and let the user search
the entries. If the search result contains 23 entries but you may want to
display no more than 10
entries at once. The first page contains entries 1-10, the second 11-20 and
the third 21-23. See the
documentation of the "Page" class for more information.

How do I use this module?
---------------------------
The paginate module contains extensive in-line documentation with examples.

Concerning WebHelpers
-----------------------
This is a standalone module. Former versions were included in the
WebHelpers Python module as
webhelpers.paginate and were tightly coupled with the WebHelpers and the
Pylons web framework. This
version aims to be useful independent of any web framework.

Subclassing Page()
------------------
This module supports pagination through list-like objects. To paginate
though other types of objects
you can subclass the paginate.Page() class and provide a wrapper class that
defines how to access
elements of that special collection.

You can find examples in other paginate_* modules like paginate_sqlalchemy.
Basically you would have
to provide a class that implements the __init__, __getitem__ and __len__
methods.

It is trivial to make pagination for other datastores like
Elasticsearch/Solr extending the base class.

Example::

    class SqlalchemyOrmWrapper(object):
        """Wrapper class to access elements of a collection."""
        def __init__(self, obj):
            self.obj = obj

        def __getitem__(self, range):
            # Return a range of objects of an sqlalchemy.orm.query.Query
object
            return self.obj[range]

        def __len__(self):
            # Count the number of objects in an sqlalchemy.orm.query.Query
object
            return self.obj.count()

Then you can create your own Page class that uses the above wrapper class::

    class SqlalchemyOrmPage(paginate.Page):
        """A pagination page that deals with SQLAlchemy ORM objects."""
        def __init__(self, *args, **kwargs):
            super(SqlalchemyOrmPage, self).__init__(*args,
wrapper_class=SqlalchemyOrmWrapper, **kwargs)

As you can see it does not do much. It basically calls
paginate.Page.__init__ and adds
wrapper_class=SqlalchemyOrmWrapper as an argument. The paginate.Page
instance will use that wrapper
class to access the elements.

Generating HTML come for current page
-------------------------------------

Example::

    p = paginate.Page([], page=15, items_per_page=15, item_count=1010)
    # item_count is optional, but we pass a dummy empty resultset for this
example
    pattern = '$link_first $link_previous ~4~ $link_next $link_last (Page
$page our of $page_count - total $item_count)'
    p.pager(pattern, url='http://foo.com?x=$page', dotdot_attr={'x':5},
link_attr={'y':6}, curpage_attr={'z':77})
    # *_attr arguments are optional and can be used to attach additional
classes/attrs to tags

Results in::

    '&lt;&lt; &lt; 1 <span class="D">..</span> 11 12 13 14 <span
class="C">15</span> 16 17 18 19 <span class="D">..</span> 68 &gt; &gt;&gt;
(Page 15 our of 68 - total items 1010)'

Using url maker to generate links to specific result ranges
-----------------------------------------------------------

You can pass `url_maker` Callback to generate the URL of other pages, given
its numbers.
Must accept one int parameter and return a URI string.
