YashRE42 b4891a5841 navbar: Rename tab_bar to message_view_header.
Prior to commit eb4a2b9d4e the center
area of the navbar was based on a structure that appended crumbs or
"tabs" as <li>s, forming a tab_bar and a tab_list.

However, in eb4a2b9d4e we apply a new
style and structure to the navbar which lets go of the convention of
tabs. Hence, we'd like to purge the tab_bar and tab_list labels from
our code base.

We purged tab_list in 1267caf5009118875f47fdafe312880af08024e1.

This commit purges tab_bar, it includes:
- A blanket search and replace of tab_bar with message_view_header.
- Splitting a single line comment in
  tab_bar.js / message_view_header.js.
- The renaming of tab_bar.js to message_view_header.js.
- The renaming of tab_bar.hbs to message_view_header.hbs.
- A blanket search and replace of tab_data with
  message_view_header_data.
- Replacing the single occurrence of tabbar with message_view_header
  (it was within a comment.)

Steve Howell 0eb206f97e mobile sharing: Make emoji.js a shared ES6 module.
This is a pretty straightforward conversion.

The bulk of the diff is just changing emoji.js
to ES6 syntax.

There is one little todo that can be deferred
to the next commit--we are now set up to have
markdown.js require emoji.js directly, since
it is no longer on `window`.

YashRE42 78d511fd03 navbar: Clean up implementation of tab_bar.narrow_description hover.
This handler adds a neat little effect whereby hovering over the
clickable region to open the navbar triggers the search_icon hover
effect and is a neat little visual cue about what happens onClick.

The previous implementation was slightly messy because it fetched the
color and applied it via ".css(". This commit cleans it up by creating
and using the class "search_icon_hover_highlight" instead. We also
make the selectors more specific, ensuring they target children of
"#tab_bar", this was so because it was reasonable to expect someone to
define eg `search_closed` elsewhere and we wanted to prevent bugs when
that happened.

YashRE42 ae7ff04fe6 navbar: Purge tab_list label from code base.
Prior to commit eb4a2b9d4e the center
area of the navbar was based on a structure that appended crumbs or
"tabs" as <li>s, forming a tab_bar and a tab_list.

However, in eb4a2b9d4e we apply a new
style and structure to the navbar which lets go of the convention of
tabs. Hence, we'd like to purge the tab_bar and tab_list labels from
our code base.

It would have been nicer if we could simply purge tab_bar from the
codebase and rename "#tab_list" so that we have an anchor and wrapper
structure in the html, but dropping the float: left on tab_bar causes
some confusing problems such as causing the horizontal border to
disappear and the search_box to shift out of its intended position and
so its simpler to get rid of tab_list from our code base first.

This commit:
- Removes the #tab_list wrapper div from tab_bar.hbs.
- Removes any #tab_list selectors from night_mode.scss so that they
  simply target based on "#tab_bar" instead of "#tab_bar #tab_list".
- Removes tab_list selectors from zulip.scss, so that #tab_list
  attributes now apply to the #tab_bar, in the process we drop the
  duplicated width property and reorder the attributes.
- Replaces all mention of #tab_list with #tab_bar in JS files.

Sara Gulotta 1cb040647b markdown: Add support for spoilers.
This adds support for a "spoiler" syntax in Zulip's markdown, which
can be used to hide content that one doesn't want to be immediately
visible without a click.

We use our own spoiler block syntax inspired by Zulip's existing quote
and math block markdown extensions, rather than requiring a token on
every line, as is present in some other markdown spoiler
implementations.

Fixes #5802.

Steve Howell b965766f87 refactor: Call compose_fade without triggers.
We are trying to phase out the trigger-event way
of telling modules to do something.

In this case we not only remove the indirection
of the event handler, but we also get to remove
`compose_fade` from the `ui_init` startup sequence.

This also has us update `compose_fade` outside
the loop, although that's only a theoretical
improvement, since I don't think `peer_add` events
every actually include multiple streams.

To make the dispatch tests a little flatter, I
added a one-line change to zjsunit to add
`make_stub` to `global`.

To manually test:
    * have Aaron reply to Denmark (keep compose box open)
    * have Iago add Hamlet to Denmark
    * have Hamlet unsubscribe

Tim Abbott 2beaf2cab2 pointer: Remove have_initial_messages code.
This was implemented in 2012 to avoid showing a loading indicator for
fetching messages for users with no message history.  However, the
Zulip onboarding UI always creates some message history, and fetching
history is fast, so this is likely clutter more than a useful
optimization.

YashRE42 30065b4ee8 navbar: Increase the click area of to initiate search.
This commit:
- Switches margin for padding on the search closed icon, to ensure we
  cover the region to the right of icon as clickable area.
- Applies the click handler that initiates the search to the second
  last element of the navbar:
  - This will most commonly be the narrow_description element, but may
    also be the entire navbar eg in the case of "ALL" or "starred".
    Applying this change to user names in "group-pm-with: ..." based
    narrows is a little questionable, but there are no other triggers
    on these names so this change makes sense for now.
  - The narrow_description may also contain links, which need to be
    handled correctly so that the behave like links should. We work
    around the onClick on the narrow_description, by applying a
    handler to <a> tags and invoking stopPropagation.
- We also add CSS to change the cursor to a pointer to make the
  search icon change color on hover over the clickable area to
  indicate that the search box can be opened with a single click.
- However, since <a> tags are handled differently, we add a hover
  listener which makes sure it behaves appropriately. We also increase
  the vertical padding of the <a> tags so they cover the entire
  vertical navbar region.

Steve Howell 1f156230b0 refactor: Clean up alert_words API.
We add these two functions to the API,
so that we no longer have `alert_words_ui`
using private data from `alert_word`:

    alert_words.has_alert_word()
    alert_words.get_word_list()

And to initialize the data, we have a proper
`initialize` method that is passed in only
the parameters that it needs from `ui_init`.

(We also move the step of deleting `alert_words`
from `page_params` to the `ui_init` module.)

Because it's a bit less cumbersome to initialize
`alert_words`, we now just it directly in the
node tests for `alert_words_ui`.

Steve Howell 5e8279c2fb refactor: Extract settings_config.
This moves some code from settings_display.js
into the new module settings_config.js.

Extracting this module breaks some dependencies
on settings_display.js (which has some annoying
transitive dependencies, including jQuery).

In particular this isolates stream_data from
from settings_display.js.

Two of the three structures that we moved here
weren't even directly used by settings_display.js,
since we do a lot of rendering in the modules
admin.js and setting.js.

We make get_all_display_settings() a function
to avoid a require-time dependency on page_params.

Breaking the dependencies simplifies a few
node tests.

Most of the node test complexity came from the
following commit in March 2019:

5a130097bf

The commit itself seems harmless enough, but
dependencies can have a somewhat "viral" nature,
where making stream_data depend on settings_display
caused us to modify four different node tests.

Steve Howell b55d2bc256 markdown: Add helper configuration for mobile.
This refactoring is the first step toward sharing
our markdown code with mobile.  This focuses on
the Zulip layer, not the underlying third party `marked`
library.

In this commit we do a one-time initialization to
wire up the markdown functions, but after further
discussions with Greg, it might make more sense
to just pass in helpers on every use of markdown
(which is generally only once per sent message).
I'll address that in follow-up commits.

Even though it looks like a pretty invasive change,
you will note that we barely needed to modify the
node tests to make this pass.  And we have pretty
decent test coverage here.

All of the places where we used to depend on
other Zulip modules now use helper functions that
any client (e.g. mobile) can configure themselves.
Or course, in the webapp, we configure these from
modules like people/stream_data/hash_util/etc.

Even in places where markdown used to deal directly with
data structures from other modules, we now use functions.
We may revisit this in a future commit, and we might
just pass data directly for certain things.

I decided to keep the helpers data structure completely flat,
so we don't have ugly nested names like
`helpers.emoji.get_emoji_codepoint`.  Because of this,
some of the names aren't 1:1, which I think is fine.

For example, we map `user_groups.is_member_of` to
`is_member_of_user_group`.

It's likely that mobile already has different names
for their versions of these functions, so trying for
fake consistency would only help the webapp.  In some
cases, I think the webapp functions have names that
could be improved, but we can clean that up in future
commits, and since the names aren't coupled to markdown
itself (i.e. only the config), we will be less
constrained.

It's worth noting that `marked` has an `options`
data structure that it uses for configuration, but
I didn't piggyback onto it, since the `marked`
options are more at the lexing/parsing layer vs.
the app-data layer stuff that our helpers mostly
help with.

Hopefully it's obvious why I just put helpers in
the top-level namespace for the module rather than
passing it around through multiple layers of the
parser.

There were a couple places in markdown where we
were doing awkward `hasOwnProperty` checks for
emoji-related stuff.  Now we use the Python
principle of ask-forgiveness-not-permission and
just handle the getters returning falsy data.  (It
should be `undefined`, but any falsy value is
unworkable in the places I changed, so I use
the simpler, less brittle form.)

We also break our direct dependency on
`emoji_codes.json` (with some help from the
prior commit).

In one place I rename streamName to stream_name,
fixing up an ancient naming violation that goes
way back to before this code was even extracted
away from echo.js.  I didn't bother to split this
out into a separate commit, since 2 of the 4
lines would be immediately re-modified in the
subsequent commit.

Note that we still depend on `fenced_code`
via the global namespace, instead of simply
requiring it directly or injecting it.  The
reason I'm postponing any action there is that
we'll have to change things once we move
markdown into a shared library.  (The most
likely outcome is that we'll rename/move both files
at the same time and fix the namespace/require
details as part of that commit.)

Also the markdown code still relies on `_` being
available in the global namespace.  We aren't
quite ready to share code with mobile yet, but the
underscore dependency should not be problematic,
since mobile already uses underscore to use the
webapp's shared typing_status module.

Steve Howell 9ab07d1038 util.js: Remove util from window.
We now treat util like a leaf module and
use "require" to import it everywhere it's used.

An earlier version of this commit moved
util into our "shared" library, but we
decided to wait on that.  Once we're ready
to do that, we should only need to do a
simple search/replace on various
require/zrequire statements plus a small
tweak to one of the custom linter checks.

It turns out we don't really need util.js
for our most immediate code-sharing goal,
which is to reuse our markdown code on
mobile.  There's a little bit of cleanup
still remaining to break the dependency,
but it's minor.

The util module still calls the global
blueslip module in one place, but that
code is about to be removed in the next
few commits.

I am pretty confident that once we start
sharing things like the typeahead code
more aggressively, we'll start having
dependencies on util.  The module is barely
more than 300 lines long, so we'll probably
just move the whole thing into shared
rather than break it apart.  Also, we
can continue to nibble away at the
cruftier parts of the module.

We'll need to do some profiling of the backend after this is deployed
in production; it's possible we'll need to add some database indexes,
denormalization, or other optimizations to avoid making loading the
Zulip app significantly slower.

Fixes #12502.

Anders Kaseorg 428956c086 zjsunit: Remove set_global side effect from zrequire.
ES6 and TS modules don’t insert themselves into `window`, so our tests
shouldn’t insert them either.  Since the test `window` behaves like
`global` now, we can rely on legacy modules that do insert themselves
to do it themselves.

Tim Abbott 500b161aab unread: Enable the load_server_counts setting for everyone.
This change is long overdue.  After implementing this much more robust
system and deploying it on chat.zulip.org, we hesitated to make
load_server_counts the default behavior in master, because of data
anomalies present for many existing users (basically messages far back
in their history that they had never read, on streams they believed
themselves caught up on), which would have been confusing for many
users.

However, because the mobile apps have been using this data set for a
long time, we've likely cleared out the anomalies from active users'
data set.  And for older users, they're going to come back to
approximately infinite unread messages anyway, so the data anomalies
are unlikely to be important.

Fixes #7096.

sahil839 5a130097bf settings: Add display setting for demoting inactive streams.
This adds a setting to control Zulip's default behavior of sorting to
bottom and graying out inactive streams.  The previous logic is still
the default "automatic", but this gives users more control.  See the
models.py comment for details.

Fixes #11524.

Steve Howell 6b39d6004e zjquery: Use Proxy to detect undefined stubs.
We now use a Proxy to wrap zjquery elements, so
that we can detect callers trying to invoke methods
(or access attributes) that do not exist.  We try
to give useful error messages in those cases.

The main impact here is that we force lots of tests
to explicitly stub `length`.

Also, we can't do equality checks on zjquery
objects any more due to the proxy object, but the
easy workaround is to compare selectors.  (This
is generally an unnecessary technique, anyway.)

The proxy wrapper is fairly straightforward, and
we just have a few special cases for things like
"inspect" that happen when you try to print out
objects.

Anders Kaseorg 01613e71fb ui: Replace set_up_scrollbar with data-simplebar attribute.
With perfectScrollbar, we needed to call a function from JavaScript to
enable a scrollbar on a new element, but simplebar has a much simpler
default API one can do by using data-simplebar attributes in the HTML.

So we can delete all the scrollbar creation/deletion code.

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.

Steve Howell 9986e41999 top left: Simplify markup for main links.
The following elements in the top left corner
are major components of our app:

    All messages
    Private messages
    Starred messages
    Mentions

We can now find them directly:

    $('.top_left_all_messages')
    $('.top_left_private_messages')
    $('.top_left_starred_messages')
    $('.top_left_mentions')

Before this, we had to build up complicated selectors
like below:

    exports.get_global_filter_li = function (filter_name) {
        var selector = "#global_filters li[data-name='"
            + filter_name + "']";
        return $(selector);
    };

I don't think any newbie would know to grep for "global_filter",
and I've seen a PR where somebody added specific markup here
to "Private messages" because they couldn't grok the old scheme.

Another thing to note is that we still have a "home-link"
class for "All messages", which overlapped with portico
code that had the same name.  (There were some inaccurate
comments in the code relating to the tab bar, but we don't
actually have a way to click to the home view in the tab
bar any more.)  I'll eliminate that cruft in another commit.

For this commit the four elements still have the
"global-filter" class, since there's some benefit to being
able to style them all as a group, although we should give
it a nicer name in a subsequent commit.

Most of this PR is basic search/replace, but I did add a
two-line helper: `top_left_corner.update_starred_count`
