getFillText() serves to decouple the text displayed in the auto-complete list
via getText() and the text actually filled into the box via getFillText(). This
allows us to display command + args on the list but only fill the command part.
A Command class has been added to provide some structure when extracting the
command name and args. Manually tested and it works.
The bug was that *sometimes* typing in some letters then
pressing tab would flash red and not auto-complete. This was
happening because nextMatchedEntry was being called with 0
because the state of inPassiveMode was wrong.
\b is *the worst*. From MDN:
Note: JavaScript's regular expression engine defines a specific set of
characters to be "word" characters. Any character not in that set is considered
a word break. This set of characters is fairly limited: it consists solely of
the Roman alphabet in both upper- and lower-case, decimal digits, and the
underscore character. Accented characters, such as "é" or "ü" are,
unfortunately, treated as word breaks.
We fix this by matching on whitespace instead, but then need to tweak the
replace() code since that bluntly replaces the entire match (which now includes
whitespace). It all works now and I can happily tab-complete non-ascii names.
This primarily means pre-calculating the list of things we'll be looping over
and then returning matches from this list. Make the regex match be more generic
rather than sorta-kinda-user-id-like-ish.
RoomView is the parent component which creates MessageComposer AND the status
bar. By making RoomView instantiate TabComplete we can scope instances
correctly rather than relying on singleton behaviour through dispatches. This
also makes communication between status bar and the MessageComposer infinitely
easier since they are now sharing the same TabComplete object.
Moved to a `TabComplete` class. Make it more generic (list of strings rather
than RoomMembers) and sort the member list by last_active_ago. Everything still
seems to work.
