django-markitup
===============

Easy integration of the MarkItUp_ markup editor widget in Django projects.


.. _MarkItUp: http://markitup.jaysalvat.com/

Installation
============

Download a release tarball from Launchpad_, or get the Bazaar trunk
version of the application::

    bzr checkout lp:django-markitup django-markitup

To install django-markitup:

    1. Put the ``markitup`` folder somewhere on your Python path.

    2. Put ``'markitup'`` in your ``INSTALLED_APPS`` setting.

    3. Make the contents of the "markitup/media" directory available
       at ``MEDIA_URL/markitup``.  This can be done by copying the
       files, making a symlink, or through your webserver
       configuration.

    4. If you want to use AJAX-based preview:
       
        - Add ``url(r'^markitup/', include('markitup.urls')`` in your
          root URLconf.
        - Set the MARKITUP_PREVIEW_FILTER setting (see `Using AJAX preview`_ 
          below).

Using the MarkItUp! widget
==========================

The MarkItUp! widget lives at ``markitup.widgets.MarkItUpWidget``, and
can be used like any other Django custom widget.

To assign it to a form field::

    from markitup.widgets import MarkItUpWidget
    ...
    content = forms.TextField(widget=MarkItUpWidget())

When this form is displayed on your site, you must include the form
media somewhere on the page using ``{{ form.media }}``, or the
MarkItUpWidget will have no effect.

To use MarkItUpWidget in the Django admin:

    from markitup.widgets import MarkItUpWidget
    
    class MyModelAdmin(admin.ModelAdmin):
    ...
    def formfield_for_dbfield(self, db_field, **kwargs):
        if db_field.name == 'content':
            kwargs['widget'] = MarkItUpWidget(attrs={'class': 'vLargeTextField'})
        return super(MyModelAdmin, self).formfield_for_dbfield(db_field, **kwargs)

Choosing a MarkItUp! button set and skin
========================================

MarkItUp! allows the toolbar button-set to be customized in a
Javascript settings file.  By default, django-markitup uses the
"default" set (meant for HTML editing).  Django-markitup also includes
basic "markdown" and "textile" sets (these are the sets available from
`the MarkItUp site <http://markitup.jaysalvat.com>`_, modified only to
add previewParserPath).

To use an alternate set, assign the ``MARKITUP_SET`` setting a URL
path (absolute or relative to MEDIA_URL) to the set directory.  For
instance, to use the "markdown" set included with django-markitup::

    MARKITUP_SET = 'markitup/sets/markdown'

MarkItUp! skins can be specified in a similar manner.  Both "simple"
and "markitup" skins are included, by default "simple" is used.  To
use the "markitup" skin instead::

    MARKITUP_SKIN = 'markitup/skins/markitup'

Neither of these settings has to refer to a location inside
django-markitup's media.  You can define your own sets and skins and
store them anywhere, as long as you set the MARKITUP_SET and
MARKITUP_SKIN settings to the appropriate URLs.

Set and skin may also be chosen on a per-widget basis by passing the
``markitup_set`` and ``markitup_skin`` keyword arguments to
MarkItUpWidget.


Using AJAX preview
==================

If you've included ``markitup.urls`` in your root URLconf (as
demonstrated above under `Installation`_), all you need to enable
server-side AJAX preview is the ``MARKITUP_PREVIEW_FILTER`` setting.

``MARKITUP_PREVIEW_FILTER`` must be a two-tuple.  

The first element must be a string, the Python dotted path to a markup
filter function.  This function should accept markup as its first
argument and return HTML.  It may accept other keyword arguments as
well.  You may parse your markup for preview using any method you
choose, as long as you can wrap it in a function that meets these
criteria.

The second element must be a dictionary of keyword arguments to pass
to the filter function.  The dictionary may be empty.

For example, if you have python-markdown installed, you could use it
like this::

    MARKITUP_PREVIEW_FILTER = ('markdown.markdown', {'safe_mode': True})

Alternatively, you could use the "textile" filter provided by Django
like this::

    MARKITUP_PREVIEW_FILTER = ('django.contrib.markup.templatetags.markup.textile', {})

(The textile filter function doesn't accept keyword arguments, so the
kwargs dictionary must be empty in this case.)

**Note:** If you use your own custom MarkItUp! set, be sure to set the
  ``previewParserPath`` option to ``'/markitup/preview/'``.


Other settings
==============

MarkItUp! requires the jQuery Javascript library.  By default,
django-markitup links to the most recent minor version of jQuery 1.3
available at ajax.googleapis.com (via the URL
``http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js``).
If you wish to use a different version of jQuery, or host it yourself,
set the JQUERY_URL setting.  For example::

    JQUERY_URL = 'jquery.min.js'

This will use the jQuery available at MEDIA_URL/jquery.min.js.
