There is a new implementation of require_js in lib/deprecatedlib.php,
based on $PAGE->requires.
There were a few other recently introduced functions in lib/weblib.php,
namely print_js_call, print_delayed_js_call, print_js_config and
standard_js_config. These have been removed, since they were never in
a stable branch, and all the places that used them have been changed
to use the newer $PAGE->requires->... methods.
get_require_js_code is also gone, and the evil places that were calling
it, even though it is an internal function, have been fixed.
Also, I made some minor improvements to the code I committed yesterday
for MDL-16695.
All that remains is to update all the places in core code that are
still using require_js.
(This commit also fixes the problem where the admin tree would not
start with the right categories expanded.)
This is a minimal fix for MDL-18554, I have just added a cancel button and made it work.
The more substantial part of this is MDL-17454, trying to make the quiz editing screen behave appropriately when shuffle questions is on. I am sure Olli will have opinions about this and want to change it further. Rought summary:
* When shufflequestions is off, never restrict manual paging, even if questionsperpage is set.
* When shuffle questions is on:
** Always display the quiz with the defined number of questions per page.
** Remove controls to add things except at the end of the quiz.
** Disable most of the order and paging tab, but still allow the question list to be reordered, in case that helps teachers track which questions they have added.
** Still allow questions to be reordered on the edit tab, but when moving the top question on a page up, reorder with the previous question, rather than moving to the previous page.
* Change the status bar, so that the yellow highlight is reserved for alert information. The more informative stuff is now plain, and moved to under the title. To my mind that associates it more closely with the quiz name. Also it moves Total of grades and Maximum grade closer together.
* JavaScript cleaned up. I learn more about YUI every day.
* Some PHP code clean ups that I forgot to commit separately before making substantive changes.
We had a !== when it should have been !=, and our constants were defined as strings not ints. This problem has been there since forever, but no one had noticed before. Thanks to Alan Trick for finally spotting it!
