Steve Howell 9f7be51ce8 streams: Replace Dict with IntDict in stream_data.
There's another Dict that we'll convert to a Set
in a subsequent commit.

Steve Howell ee3e488e02 js: Extract FoldDict class.
We have ~5 years of proof that we'll probably never
extend Dict with more options.

Breaking the classes into makes both a little faster
(no options to check), and we remove some options
in FoldDict that are never used (from/from_array).

A possible next step is to fine-tune the Dict to use
Map internally.

Note that the TypeScript types for FoldDict are now
more specific (requiring string keys).  Of course,
this isn't really enforced until we convert other
modules to TS.

Tim Abbott 89ff62dafa topic_list: Limit number of unread topics shown at once.
This avoids a stream having potentially near-infinite height when
opened in a stream with a large number of unread topics; the benefit
is that you can easily access the next stream.

We show an unread count next to "more topics" to make it hard to miss
that there might be more, older topics with unread messages.

With CSS work by Anders Kaseorg.

Fixes #13087.

Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`.  It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

Anders Kaseorg d17b577d0c js: Purge useless IIFEs.
With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

Anders Kaseorg 141088586b Completely replace perfect-scrollbar with SimpleBar.
perfect-scrollbar replaces both the appearance and the behavior of the
scrollbar, and its emulated behavior will never feel native on most
platforms.  SimpleBar customizes the appearance while preserving the
native behavior.

Challa Venkata Raghava Reddy 8623a02d98 streams: Avoid showing more topics option when it's useless.
This makes the "more topics" option which appears below the list of
known topics in the left sidebar appear only when it's possible there
are actually more topics to be displayed.  Two specific cases it
resolves completely include:

* Newly created realms; this widget was a common source of confusion
  for new organization administrators.
* Newly created streams.

There are still some corner cases this doesn't handle, e.g. if you
just joined a private stream with protected history, but there isn't
as easy a fix for those.

Essentially rewritten by tabbott to fix code duplication and comment
extensively.

Fixes #10265.

Steve Howell 597c812300 refactor: Use a Dict to track active topic widgets.
Even though there are only ever zero or one active
topic widgets in our current sidebar, it's almost the
same amount of code to just manage them with a Dict.

Also, we can more easily do possible future features
like setting streams to be always-open.

Steve Howell c8cee5d900 topic list: Remove unnecessary markup.
The data attribute here has some value if you're
inspecting the HTML in the browser, but it's not
worth the extra code.

All the list items have data-stream-id, so there's
no need for the parent to have it.

Steve Howell a8718c9051 muting: Use stream_id for internal data structures.
This fixes the most core data structures inside of
muting.js.  We still use stream names for incoming
data to set_muted_topics and outgoing data from
get_muted_topics.

This will make us more resilient to stream name changes.
Before, if you were logged on when a stream rename
occured, topics that were muted under that stream would
appear to be unmuted.  (You could fix it with a reload,
but it can be jarring to have a bunch of unread messages
appear in your feed suddenly.)

Steve Howell acb7149386 Extract topic_zoom.js.
This small modules nicely breaks down the
responsibilities of topic_list and stream_list
when it comes to zooming in and out of topics
(also known as hitting "more topics" or "All
Streams).

Before this, neither module was clearly in
charge, and there were kind of complicated
callback mechanisms.  The stream_list code
was asking topic_list to create click handlers
that called back into stream_list.

Now we just topic_zoom set up its own click
handlers and delegate out to the other two
modules.

Steve Howell ab26e27fef Move stream-related uri helpers to hash_util.
This allows several modules to no longer need
to import `narrow` (or, in our current pre-import
world, to not have to use that global).

The broken dependencies are reflected in the node
tests, which should now run slightly faster.

Armaan Ahluwalia 6d255efe4c app: Prepare JS files for consumption by webpack.
This commit prepares the frontend code to be consumed by webpack.

It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.

However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.

So we expose the modules by setting window.varName = varName; as
needed in the js files.

Tim Abbott 7ab8a8e820 js: Fix a bunch of indentation issues found by eslint.
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.

Steve Howell 9f10cc62d6 Show a message when there are no more topics.
This commit is a bit complicated, because we do full redraws of

our "No more topics found" message, so we need to keep a bit of
extra state around.

Steve Howell 28a0139863 refactor: Simplify `max_topics` in topic_list.js.
We were parameterizing max_topics, but it made the calling sequences
unnecessarily complicated.  We don't ever override the value, not
even in tests, so now we just set in build_list().
2017-09-26 13:58:54 -07:00
Steve Howell 99fe3773df topic list: Refactor build_list().
This puts build_list on the widget object, which will make it a
bit easier to unit test, and it's more consistent with the rest of
the function.  This also reduces the scope of the `my_stream_name`
variable and moves the initialization of `self.topic_items` into
build_list.

Steve Howell 7da4dcd692 topic list: Ignore late server responses.
If a user re-narrows to another stream before our server gives
us more topic history, or they zoom out, we can avoid drawing
the topic list.  Note that our data structures will still be
updated, although the only time that really matters is for
the corner case of a low-traffic stream.  For a low traffic
stream that only had 3 or 4 topics in the original message
fetch, but has longer history, the next time you open the
stream in the sidebar, even when you're zoomed out, you will
see more topics.

Steve Howell 46e8005bfb Inline feature_flags.use_server_topic_history.
Despite a few warts, we are going forward with getting topic
history from the server when you click "more topics."  This
commit simplifies the code by removing the feature flag
checks.

Max Schaefer 4825b6e5ad topic_list: Remove a spurious assignment and simplify a conditional.
Variable `show_topic` was assigned in both branches of the
conditional, but the assignment in the "then" branch was useless,
since the variable wasn't subsequently read. Hence the assignment can
be dropped, leaving the "then" branch empty. The "if" statement can
then be simplified by removing the "then" branch entirely and flipping
the condition. Since `show_topic` is now only used inside the "if", it
is slightly tidier (though semantically equivalent) to move its
declaration inside.

Steve Howell 60cca43d5e Always show "more topics" link if you have server history.
Until we have an easy way to consistently determine whether a
stream has more topics than have been loaded already, we err
on the side of showing a "more topics" link.  This in some ways
leads to a more consistent experience where you can zoom in on
any stream, even one that's really new.

Steve Howell 24e9dbe80b Use data-stream-id for zooming topics. 2017-08-11 13:01:39 -07:00
Steve Howell fad024ebda Simplify stream sidebar narrows.
This fix simplifies how we re-render topic lists when we
re-narrow or zoom out from a topic list.

    * The topic_list.zoom_out() no longer gets called as
      part of re-narrowing, and we eliminate the clear_topics
      option.

    * For all situations where we narrow to a filter that does
      not have a topic, we simply call the new function
      clear_topics().

    * The stream_list code no longer calls remove_expanded_topics()
      in cases where the new narrow has a topic.  This allows us
      to optimize away scroll/flicker churn a little more easily.

As part of this, we rename maybe_activate_stream_item() to
update_stream_sidebar_for_narrow(), since the function clears
stuff as well as turning stuff on.
