While this change is not 100% required now, it's good habit
and we are checking for it since Moodle 4.4.
All the changes in this commit have been applied automatically
using the moodle.PHPUnit.TestReturnType sniff and are, exclusively
adding the ": void" return types when missing.
There are a few tests in core that are commented since the
beginning. That's not useful at all, so with this commit we
are un-commenting them instead.
Note that this is an initial step to have them back with skipped
outcome. Later in this issue we'll decide about to keep them or
completely remove them (each test can have a different outcome).
When a closing comment is used, such as when we wrap css with the
rtl:begin:ignore and rtl:end:ignore (the latter being the closing),
it is ignored in the following case:
- If the closing comment is the last item in a csslist like:
div {/*rtl:begin:ignore*/left:20px; text-align:left/*rtl:end:ignore*/}
in which case there is no css rule following the comment for it to be
associated with. It is therefore not seen and registered, meaning we
continue ignoring rtl (a bug).
In such cases, we should either:
- ensure the comment is not the final element in the css list
- use self-closing (/*rtl:ignore*/) comments for each rule instead.
- use a self-closing comment on the entire css list, if applicable.
The core_rtlcss class extends the \MoodleHQ\RTLCSS\RTLCSS class. This
upstream library had tests, but these were not included in core. This
change uses those test cases to test core_rtlcss, to make sure future
lib changes don't break the css parsing.
