Steve Howell ab34ee0800 search performance: Stop at max_items.
Once we have max_items results, stop trying
to get more items.

This should really help large realms when
you do a search on streams that turns up
more than N streams (where N is about 12).
We won't even bother to find people.

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.

Shubham Padia b961093c14 search: Open typeahead on empty string only if lookup triggered by Tab.
Fixes part of #10026.
Adds additional option to typeahead:
`tabOpensEmptyTypeahead`(default: false):
tabOpensEmptyTypeahead overrides helpOnEmptyStrings.
This commit sets helpOnEmptyStrings to false and
tabOpensEmptyTypeahead to true. Now typeahead will
open on an empty string only if Tab has been pressed.

Steve Howell 06b1aece31 Simplify narrow/search interactions.
Before this change, if you hit ESC, then hotkey
code would call search.clear_search, which would
call narrow.deactivate(), which would then use
`$('#search_query')` to clear a value, but then
let search.clear_search blur the input and
disable the exit button.  It was all confusing.

Things are a bit more organized now.

Now the code works like this:

    hotkey.process_escape_key
        Just call narrow.deactivate.

    $('#search_exit').on('click', ...):
        Just call narrow.deactivate.

    narrow.deactivate:
        Just call search.clear_search_form

    search.clear_search_form:
        Just do simple jquery stuff.  Don't
        change the entire user's narrow, not
        even indirectly!

There's still a two-way interaction between
the narrow.js module and the search.js module,
but in each direction it's a one-liner.

The guiding principle here is that we only
want one top-level API, which is narrow.deactivate,
and that does the whole "kitchen sink" of
clearing searches, closing popovers, switching
in views, etc.  And then all the functions it
calls out to tend to have much smaller jobs to
do.

This commit can mostly be considered a refactoring, but the
order of operations changes slightly.  Basically, as
soon as you hit ESC or click on the search "X", we
clear the search widget.  Most users won't notice
any difference, because we don't have to hit the
server to populate the home view.  And it's arguably
an improvement to give more immediate feedback.

Shubham Padia 28589c5563 search pills: Backspace should remove a search pill with typeahead open.
Fixes part of #10026.

Typeaheads stopped propogation of keydown and keyup events for any
key except tab and enter. If stopAdvance was true even tab and enter
were not allowed.

advanceKeyCodes option was added to typeahead which allowed to specify
key codes for which propogation of keydown and keyup events should not
stop. advanceKeyCodes does not respect the stopAdvance option.
As the backspace key code is added to advanceKeyCodes in search.js,
the backspace key deletes pill on pressing backspace if input is empty
or only consists of spaces.

Shubham Padia 9b1dc48ebd keyboard-shortcuts: Focus instead of select on `/` if search pills enabled.
If search pills are not enabled, the text present in the search bar
will be selected on pressing '/' and writing someting without deselecting
the text will clear the search text. Since selecting the pills would
not make sense in this context, the search box is focused instead.

Shubham Padia 22b2393cae pills: Use `widget` instead of `my_pill` throughout the app.

instead.

Shubham Padia 1f553a41d0 search: Higlight `#searchbox` on focus.
Adds box-shadow to `#searchbox` when either `#search_query` or any
of the pills have focus. Uses jquery instead of pure css as the
`:focus` event occurs on `#search_query`, while we want to add
box-shadow to `#searchbox`. This could have been done with
`:focus-within` CSS selector, but it is not supported in IE or Opera.

`#search_query` already had an onfocus/focusout listener, adding
listeners to `#searchbox.pills` for those events wouldn't have worked
as you don't want the focusout event to fire when the focus shifts
from input to pill.

Also adds `focusin`, `focusout` and `css()` to zjquery. `css` is
same as `val`, except it returns an empty object in case of no value
instead of an empty string. I don't think `css()` is valid syntax
in actual jquery.

Shubham Padia 8b153f6452 search: Validate suggestion against existing operators.
After adding search pills, suggestions were based only on the
current input and no validation against the existing pills was done.
operator_subset_suggestions have been removed. Default suggestions
for base_operators have also been removed.
Handle multiple operators:
if `is:starred stream:Ver` was typed without selecting the typeahead
or pressing enter in between i.e search pill for is:starred has not yet
been added, then the description of `is:starred` will act as a prefix
in every suggestion.
Also makes changes re-enabling person suggestions for names with spaces.

Shubham Padia 36707a33ca search: Add a basic implementation of search pills.
Following points have been implemented in this commit:
1.) Add search pill on selecting typeahead.
2.) Re-narrow after removing a search pill.
3.) Add quiet optional parameter to removeLastPill.
4.) Pre populate search pills in narrow.activate.
5.) Clear existing search pills on narrow.deactivate.

Description of above points:
1.) I tried out using the description from suggestions.lookup_table
to append a pill using appendValidatedData so that the description
had not to be calculated again. But the description in the suggestions
lookup contains html due to highlighting. This html is escaped when
inputed in a pill. An attempt was also made to remove the higlighting
by replacing the tags. But other espaced characters like &lt; also
popped up, so it was better to use append_search_string.
3.) If one wants to refresh the pill using pill.clear and wants to
repopulate them, evaluating the event_handler associated with the
action of removing the pill may not be desired.
4.) Pill population code is added to narrow.activate. Pills are not
populated if the narrow was triggered by search as search handles the
addition and removal of pill by itself. The reason for not handling
search too in narrow.activate is to avoid clearing the pills and
repopulating them. Example of some of the triggers for narrow.activate
include `restore draft`, `topic change`,`sidebar`.

Also modifies tests for search.js

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.

Shubham Dhama 9b5986d320 search: Fix "Enter to search" while using an input method.
NOTE:   To test this locally I've used Google Chrome input tool.
        This change will not affect users who don't use input tools.

Here is the algorithm used to deal with this case and other important
points:

* Here I've used `compositionend` event which is triggered
as soon as an input tool completes a word or user press "enter"
to get the suggested text. (There was a situation where it is
triggered even when input tool wasn't closed, that is when we
press space, but it also triggers another `compositionstart`
event simultaneously so our logic can't be affected by this.)

* We are using a variable `is_using_input_method` which sets to
`true` when `compositionend` event is triggered.

* Basically our searching is initiated by `keyup` event which
is triggered by the same keypress which triggers `compositionend`
event to get the text, so our main goal is to suppress the searching
triggered by this key pressing.

* Observation shows that `compositionend` is triggered before the
`keyup` and calling of callback `narrow_or_search_for_term`
used by typeahead.
    i.e. chronological order of triggering of this event is
`compositionend` > calling of `narrow_or_search_for_term` > `keyup`.

* So the main logic is to set `is_using_input_method` to `false`
by default and if used the input tool then when we press enter
to get the suggested text we set it to `true` which indicate
further events triggered after it to skip the searching and
finally in `keyup` we set it to default `false` so when pressed
enter again we have it set to false and we have a successful
search.

Fixes: #9396.

"switch/case" indentation.

Steve Howell 8eb86335b9 Extract narrow_state.js.
Despite the length of this commit, it is a very straightforward
moving of code from narrow.js -> narrow_state.js, and then
everything else is just s/narrow.foo()/narrow_state.foo()/
(with a few tiny cleanups to remove some code duplication
in certain callers).

The only new functions are simple setter/getters that
encapsulate the current_filter variable:

    narrow_state.reset_current_filter()
    narrow_state.set_current_filter()
    narrow_state.get_current_filter()

We removed narrow.predicate() as part of this, since it was dead
code.

Also, we removed the shim for narrow_state.set_compose_defaults(),
and since that was the last shim, we removed shim.js from the app.

Steve Howell c4d598b36e Move parse/unparse from narrow to Filter.
I'm trying to move well-isolated methods out of narrow.js, so that
narrow.js is more strongly focused on UI/ajax interactions and
big, heavy lifting stuff.  The logical home for parse/unparse
seemed to be Filter, and they brought along two private methods
with them.  The big code moves involved trivial follow ups
like s/exports/Filter/.

3. Greatly reduce the scope of the search_object var in search.js.

I also clarified the comment around it a bit. We could squeeze
the scope of search_object even further by using a function wrapper, but
this is a big enough win for now.

Scott Feeney 8703134a23 Replace $.each with _.each
In a few cases the $.each was doing something imperatively that was
terser and easier to understand by using a different Underscore method,
so a few of these I rewrote.

Some code was using the fact that jQuery sets `this` in the callback to
be the item; I rewrote those to use an explicit parameter.

Some code was using $(some selector).each(callback). I converted these
to _.each($(some selector), callback).

One function, ui.process_condensing, was written to be a jQuery $.each
callback despite being in a totally different module from code using it.
I noticed this and updated the function's args.
