jQuery ajax requests containing multiple '?' get replaced with a
string similar to jQuery152330039032_1231231, this is because it
is processing a stringified data object as jsonp and thinks its a url.
workaround is to add contenttype
see https://github.com/jquery/jquery/issues/1799
This is required for when helpers include json-encoded variables as arguments.
As an example, imagine a template with content:
{{# str }} somekey, someidentifier, { "fullname": "{{ fullname }}" } {{/ str }}
If the fullname variable were to include the double-quote character (e.g.
John "Trevor" Doe) because of the way in which mustache renders content, it
would become:
{{# str }} somekey, someidentifier, { "fullname": "John "Trevor" Doe" } {{/ str }}
This results in an invalid JSON structure.
To work around this issue, the quote characters in the passed variable
must be escaped:
{{# str }} somekey, someidentifier, { "fullname": "John \"Trevor\" Doe" } {{/ str }}
Unfortunately, Mustache provides no way of doing so natively.
With this function, we can quote the text as appropriate:
{{# str }} somekey, someidentifier, { "fullname": {{# quote }}{{ fullname }}{{/ quote }} } {{/ str }}
This also handles the case where the quoted content includes the Mustache
delimeter ({{ or }}).
For example:
fullname = 'John "}}Trevor{{" Doe'
Ordinarily this would be rendered as:
{{# str }} somekey, someidentifier, { "fullname": "John "}}Trevor{{" Doe" } {{/ str }}
This rendering is both a JSON error, and also a mustache syntax error because of the mustache delimeters.
The quote helper also escapes these by wrapping them in change delimeter
tags:
{{# str }} somekey, someidentifier, { "fullname": "John "{{=<% %>=}}}}<%={{ }}=%>Trevor{{=<% %>=}}{{{{=<% %>=}}" Doe" } {{/ str }}
Introducing both APIs in moodle along with:
- search_box widget to add a tiny search box
- admin settings with setup steps helper
- cache for search results
- template for a search result
- php unit stuff

In some cases, underscores in lang codes get replaced with dashes
which causes some JavaScript to be unhappy. This patch simply reverse
the underscore to dash replacement on the JS side.
Quickly navigating via the keyboard to an autocomplete
element and hitting down would result in the selections
being displayed and then quickly removed. This has now
been fixed.
Fixes 3 problems with deselecting items in an autocomplete field:
1. Keep track of whether items were in the offical suggestion list, or are newly created
tags and remove the "newly created tags" from the suggestion list when they are
deselected
2. Change the aria-role for the selected items list when items cannot be deselected (and
do not treat it like a multiselect list).
3. When leaving and returning focus to the selected items list, remember the last
active-descendant.
Stopped the keyboard navigation from completely deleting
list options when being deselected using keyboard navigation.
They are now returned to the list of available options to be
reselected.
Also remove the cross from the selected element when it is
a single select box.
