TODO for Plone
==============

[also some general todos. Some of these are firm ideas, others are
just idle thoughts]

===============
Plone 2.1 todo
===============
1. fix bugs
2. Make Kupu use the Resource registry to optimise JS and CSS files.

Other thoughts
===============
Make the toolbar customisable from Plone control panel, possibly by
making the kupu tool into an action provider.
[DB: I'm not sure this will work as I think the information we need is
rather different than the usual action provider. After all, our
actions are all client side javascript not server-side methods.
However the general idea is good.]

Make the initialisation data driven so it can be more easily
customised (and driven from plone cpanel.

Add user-level documentation to kupu.oscom.org. Make the Plone
butterfly direct to a plone specific documentation page?

Improved source editing mode? At the least we should apply the content
filtering when switching into source mode.

Need a pulldown to set classes on non-block tags: e.g. span, a, etc.

Make the ul/li pulldown options customisable through cpanel, allow
them to set classes as well as list-style-type.

Refactor classes to do proper base class initialisation. This also
means we need to use .prototype. consistently for methods.

Move Plone paragraph styling back into the common code.

Generic RPC mechanism to allow tools to be defined entirely on the
server?? JSON-RPC?

Triage on the issue tracker: which issues are still valid, which are
fixed or otherwise outdated, which do we fix and which are unfixable.

Make it easier to enable the output transforms. Hotfix ATCT?

====================
Backport into common
====================
Merge PloneKupuUI class back into common so that other variants of
kupu can support classnames on styles.

Code to make links relative should also be shareable.

Collapse saveDataField and prepareForm together:

-  Maybe make _serializeOutputToString use config to select body or
   full html.

-  prepareForm should accept field name or field object and only
   create output field if it doesn't already exist.

-  makeLinksRelative should accept configurable pattern for URLs which
   are to lose their path completely. For Plone this should default to
   resolveuid.

================
TODO for drawers
================

These are probably core issues rather than specifically Plone.

- image drawer should go straight to the correct location when opened
  on an existing image (is this even possible?) so you can adjust
  alignment, captioning etc. without having to reinsert the image.

- add toolbox drawer to run macros which aren't deemed important
  enough to be directly on the toolbar.

- Uploading an image doesn't let you float the image. Perhaps the
  upload handler should simply refresh the drawer with the uploaded
  file selected, then you can set all the usual image options on an
  uploaded image.

And a Plone one:

- Want an Archetypes widget which uses Kupu drawers so we can easily
  incorporate them into reference pickers etc. This should be easier
  now we have multi-instance Kupu as we no longer need to care whether
  or not there is already a Kupu on the page.

=====================
IE problems and fixes
=====================

o importNode(node) fails on XML Document nodes. Use
  node.cloneNode(true) as a hack.

o drawer changes height when navigating with IE. Fixed by forcing the
  entire drawer to refresh in IE, but there must be something simpler we
  could do to have the same effect.

========================
Other assorted ideas

To do this properly will require some effort (which is why I haven't 
attempted to do it prior to the Plone 2.1 release).

On the server we need to find out the available sizes for the images. I 
guess that information isn't in the catalog, and we don't want to hit every 
image when sending a listing, so the only option would be to assume that 
every object with a given portal type has the same list of scales (I'm not 
even sure how it easy it is to get a list of scales from the type rather 
than from an instance of the type). Alternatively we add a list of scales 
to the configlet which would allow you to restrict the list to a useful 
subset.

That information then has to be sent to the kupu client. I think probably 
we have to send a separate list of sizes for each image (you might have 
multiple portal types not all of which are scalable) or maybe just for 
each portal type. By this point I'm thinking that what we actually have is 
a set of qualifiers which can be added to the image URL rather than 
necessarily being sizes. For example you might want to add support for 
greyscaling images or for cropping.

On the client side we need to add the modifier to the image dialog, either 
as a select box or radio buttons (probably determined by the number of 
options) and then we need to modify the url to match.

I would like to see if we can rationalise the xml to avoid adding new tags 
for every new feature to be sent from the server. Also it would be nice to 
see if there is a way to avoid changing the client js every time some 
feature such as this is added. This might be part of a more general 
refactoring of the drawers such as I know Paul is keen to try.

One option would be for the xml to include a section such as:

<options>
  <type name="Image">
    <input name="alt" size="40">Alt text</input>
    <radio name="align">
       <option value="image-left">Left</option>
       <option value="image-centre">Centre</option>
       <option value="image-right">Right</option>
    </radio>
    <select name="size">
       <option value="">Normal</option>
       <option value="/mini">Medium</option>
       <option value="/thumb">Small</option>
    </select>

    <checkbox name="captioned">Add a caption</checkbox>

    <action type="text/javascript"><![CDATA[
       if (options.alt) node.alt = options.alt;
       node.className = options.align.value;
       node.url = url + options.size.value;
       if (options.captioned) {
         node.className += " captioned";
       }
    ]]></action>
  </type>
</options>

So for a given portal_type (and we would have to add the type to the xml 
returned) some controls (select, checkbox, radio, text input) could be 
added to the dialog, and when the image is inserted the associated 
javascript would be executed in a function with parameters node, 
url,className,options to modify the newly inserted image.

[This isn't fully thought through yet: we also need to get the drawer 
picking up existing image settings, the alt text needs to get a default 
from somewhere, and the image size needs to be set somewhere on the tag.]

The last of these makes life a bit harder since the size now depends on the 
exact URL we generated. I suspect we should add an onload handler to every 
image in kupu and when the image successfully loads make it update the tag 
to the correct size. The onload attribute will of course be stripped when 
the file is saved.


=================================================


Arrange a Kupu sprint

=================================================
Drawer improvements:

Access schema to find things like image sizes, and possibly also
control other fields to appear in the drawer form. See
http://svn.plone.org/view/collective/ATContentSearch/trunk/ATContentSearch.py?op=file&rev=0&sc=0

Enable xsl includes in the drawer code so that the form can be
customised.

Change selection to display using a radio button instead of (or as
well as) highlighing the line. This allows clicking on the radio
button to select folderish content, clicking on the title navigates
into folders but selects other content.

Multiple selection done by replacing radio button with a checkbox.
Also add a library which shows just selected content. Make popup a
reference widget for Archetypes which uses kupu drawers in multiple
selection mode.

Make the widget aggressive: i.e. it will actively seek
out schemas which use the default AT reference widget and replace it,
but if the user does not have Kupu selected as their editor the
original reference widget will display instead. (This means nobody
will have to modify their content types to get the new behaviour).

Make ReferenceTextField aggressive in the same way. Add configuration
options to select whether TextField and ReferenceWidget are hijacked.

The drawers really ought to be in a separate DIV: the XSL tries to
create forms, but since the drawer is already inside a form this is
illegal and sometimes crashes IE as a result.
