This is preparation for enabling an eslint indentation configuration.
90% of these changes are just fixes for indentation errors that have
snuck into the codebase over the years; the others are more
significant reformatting to make eslint happy (that are not otherwise
actually improvements).
The one area that we do not attempt to work on here is the
"switch/case" indentation.
Normally the "n" key skips over muted streams, but if we
are currently narrowed inside a muted stream, it will now
go to the next topics within that stream.
For me the use case was that I have a stream I check up on
about once a day, and "n" would be super useful for me to
clear out unread counts while still skimming some content,
and without having to temporarily unmute the stream.
We now use similar code for A/D hotkeys as we do for the "n"
key.
The old code was using jQuery operations that got tripped up
by our splitters between active and inactive streams.
Fixes#4569
This allows us to traverse a list backwards, cycling to the
bottom as needed.
This code is going to be used for the "A" key that cycles
upward in the stream sidebar. It's probably overkill for
that use case, but it does give us O(1) behavior and avoids
the pitfall of accidentally mutating a list when reversing it.
This new module tracks the recent topic names for any given
stream.
The code was pulled over almost verbatim from stream_data.js,
with minor renames to the function names.
We introduced a minor one-line function called stream_has_topics.
We now have all of our callers into recent_topics code just
receive a list of topic names from get_recent_topic_names().
This is more encapsulated than handing off tiny little
structures to the three callers, two of whom immediately
mapped the objects to names, and one of whom needlessly
used the now defunct name canon_subject field.
The consolidation here removes some "subject" references, and
now all lookup are by stream id, not stream name.
The diff here is a bit daunting, but it's mostly simplification
of tests and calling code. Two of the callers now need to look
up stream ids, but they are otherwise streamlined.
The main change here is to stream_data.js, and we replace the
`canon_subject` and `subject` fields with `name`.
We now use "map" to have our inner generator of topics be
mapped to objects with both the stream and topic. Thanks to
Mahim Goyal for helping with this design.
