This ensures that:
- Plugins are only used once,
- Group names are unique,
- Lines match: group = plugin[, plugin[, plugin ...]],
- There are some groups and plugins defined,
- The plugins used are installed.
Previously, we hardcoded a list of icons for Atto plugins. This is not
a good idea as it would be very quickly outdated, or incomplete. Now,
we proceed as we often do: if the image pix/icon exists in the plugin
it is displayed, else nothing is displayed.
Before the patch it was happening that the undo or redo buttons
were enabled even though clicking on them didn't produce anything.
This is partly because we were not storing the initial value, we
allowed for the stack to be empty, and we were using not clean
HTML.
We set a min-height and a height in JavaScript to force the editor
to start at a certain height, but then it can be expanded thanks
to the CSS property resize. Though as IE does not support the resize
property we ignore we do not set a height so that the editor expands
as we type.
This removes alot of complex, hard to test, hard to debug code from the editor so
we can focus on the things we want to spend time on. Rangy seems a good choice for
browser support, stability and features.
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.
