This equation editor relies on whatever the currently configured filter is to do the rendering.
If there is no filter that handles latex ($$ blah $$) - this plugin will not show up.
This will not work with the solutions on the forums of adding MathJax in the header of the page,
but it will work with a real mathjax filter written for Moodle (work in progress). It works with
the existing tex filter.
Remove flaky inline menu icons - instead clicking on the table button, when
you are in a table shows the context menu for the current cell.
I removed all the special code for 'atto_control' - because it did not work very well. Having non-contenteditable
nodes inside a contenteditable region seems in expose bugs in different browsers.
toolbar order (base it on tinymce)
change plain to paragraph
default for collapse plugin should be 5 groups
fix alignment of table dialogue form
insert newlines in html generated by table plugin
rename accessibility helper to screenreader helper
remove accessibility hint for images and media files
fix some broken plugin names
style table captions
remove verbose accessibility hints
1/ Set the aria-labelledby attribute on the contenteditable div (find the label from
original textarea)
2/ Store/restore the selection for the contenteditable div when it is focused. This allows
you to select some text, then go to the toolbar and click a button, and the selection
will be restored before the button effect is applied.
3/ Add an accessibility helper plugin.
From testing in all screenreaders, I found that all of their support for contenteditable is not great.
They treat it like a textbox - which means you can type and edit text, but it tells you nothing about
the styles, links or images in the editor. So I added a button to the toolbar, that is only accessible
when navigating via keyboard, that opens an accesssibility helper dialogue. The dialogue shows the list
of current styles, a global list of all links, and a global list of all images. Choosing an image or link
from here, will focus on the editable region, and select the link/image.
4/ Add an accessibility checker plugin to Atto.
Checks for images with no alt, images and links with filenames as alternate text/link text, and contrast ratios
less than WCAG 2.0 AA.
The previous change on this issue accidentally fixed a selector,
so the repository API was recieving a valid node instead of null.
This means that it calls it's undocumented and dodgy callbacks on the node,
which are really calls directly to the TinyMCE API (just well buried).
But - by not setting the editor_target property, the api will not do
the secret handshakes.
If plugins try and do this themselves with Y.one, they will fall foul of the
qtype essay page bug which uses : in the id for form elements.
This is an alternative solution, to escaping the ids, which seemed unreliable for older
version of ie.
The cleanup rules are pulled from both testing of live docs, and the
jquery clean plugin. I tested with googledocs, libreoffice, word 2003
and word 2013.
Rewrite the atto plugin loader so that:
A) We have a real settings.php page and can edit the toolbar.
B) All plugins are loaded at the same time (not serially)
C) All plugins share the YUI sandbox (more performance boost).
I had to change the loading API for this - but there are not non-core uses yet,
this is the best time to break it.
