Why is util.encode
used here?

Because the code can contain XML-like tags which will be parsed as HTML because I use env.element.innerHTML
.
Also, it's what highlight
does.

Ah, and this was handled previous here:
env.element.textContent = env.code;
which uses textContent
rather than innerHTML
.

This PR fixes the bug described in #1706 (also includes a demo).
The problem was that the
insert-before
hook was not called ifgrammar
is undefined.This also fixes that
callback
was not called in that case and thatenv
of thecomplete
hook did not have ahighlightedCode
property.All other hooks are unchanged. The
insert-before
hook is only used by the Command line plugin, so there should be no other side effects.
