Changed <h5> to <p>, and removed the special formatting of
.empty_search_text to make this more in line with the formatting we
generally use with empty narrows.
Also adds relevant tests and documentation. We currently
do not narrow to a new topic, and instead just narrow to
the stream. Similarly, we do not narrow to a PM if any of
the recipients are invalid.
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.
If a user is narrowed by `is:private`, `pm-with`, or `group-pm-with`,
change the `New topic` button to say `New stream message` instead for
added clarity.
Also, add to the Casper and Node tests for this behavior.
Fix#9072.
When visiting a narrow like
https://chat.zulip.org/#narrow/stream/doesnotexist, grey-out the reply
button and add the title `There are no messages to reply to.`
Also, add to the tests for `narrow.js` with
`#left_bar_compose_reply_button_big`.
Fix#8547.
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.
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 < 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
We now use narrow_state.filter() everywhere. The
two functions did the same thing, and I slightly
prefer the concise name, which was already in use
in lots of places.
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.
We had a significant amount of code for handling what seemed to be 2
cases, but which were really just a single case (if we are trying to
narrow to a specific message ID, and we end up landing on it, restore
the previous offset; with the special case that the previous offset
might be passed in from the previous call).
This cleanup also fixes a very minor bug, where our background
auto-reload (`reload.initiate({immediate: true});` in the JS console)
would incorrectly reset the pointer position to match the a near:
message ID if that was present in the narrow.
This commit fixes a couple regression related to narrowing.
For a long time we've had bugs where we too aggressively
preserve the currrent selection on topic -> stream
re-narrows ("s" key) even when the wider narrow may
have unread messages before the selection.
Also, we recently introduced a bug so that when you used
a link from the "copy link to conversation" (aka a "near"
query), it would advance you to your first unread message
despite the near:999 specifier. (The code would work for
subsequent "near" queries once you had fetched some of
your original messages).
This commit introduces a new data structure called id_info (replacing
the select_strategy data structure) in various functions and uses that
to track all the ids of relevance.
Significantly rewritten by tabbott to handle a few extra corner cases,
and add a ton of comments explaining why it works the way it does.
Fixes#2091.
Fixes#9606.
The "if" condition that was removed in this commit
is no longer needed, since the called code now
handles the cannot-apply-locally use case. (We
wanted the called functions to be defensive, so
they already were effectively handling the conditions
anyway, and recent commits has them returning
appropriate values and doing the right things.)
We had debug code that was reaching into msg_list._items when
it could use msg_list.all_messages() instead.
When we split out MessageListData, using _items started
breaking this code.
We now work with MessageListData objects while populating
data from local narrows, before actually making the
wrapper MessageList object.
This change will simplify unit testing (less view stuff
to fake out) in certain situations.
It will also allow us to eliminate the delay_render flag.
We used to have positional parameters for table_name
and filter, but we don't use them for message_list.all
and we're about to replace filter in some cases.
Passing everything in on opts is more consistent and
self-documenting in the calling code, plus lots of
unit tests can get away with passing in `{}` now
for situations where table_name does not matter.
All of our callers pass in muting_enabled, so we
remove the default value for it. And then the
collapse_messages variable doesn't have to live on
`this` as it's only being passed through down to the
view.
We now only preserve the offset for the previous
selection (pre-narrow) if that is still the id
we want selected after calling maybe_add_local_messages.
Right not this does not change any behavior, but
upcoming changes to maybe_add_local_messages will
change the selected id to the first unread message
in certain circumstances, in which case preserving
the offset will possibly be confusing, since you're
not on the same message.
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.
For a commit that was just merged I had the "back-out" case
at the wrong nesting level. It was a pretty obscure failure
scenario that never came up in practice, but basically if you
were starting at a message that was not in your narrow, but
we did have some messages in your narrow, we would try to
go near the old message instead of talking to the server to
find the next unread message in that narrow.
Barring a few minor edge cases, when we now do a narrow
that is based on a sidebar-like search (e.g. stream/topic,
no extra conditions), we now go directly to either the
first unread message we know about locally or the last
message if we're all caught up.
We of course used to do this in master until recently; this behavior
was broken by Tim's narrowing refactor branch (ending with
26ac1d237b) which moved us to always
using the select_first_unread flag, by default (fixing issues where if
you clicked around while your pointer was behind, you'd land in the
wrong place).
We now have arguably the best of both worlds:
* The pointer is not considered when computing narrowing positioning
* We only go to the server for sidebar clicks if the data isn't
available in the browser.
This is purely to make it easier to read narrow.activate()
without having to page past lots of unnecessary detail when
you're trying to understand things like how we set the
selection.
The maybe_select_closest helper, when first introduced, was
tiny and close to its callers.
As it's grown, it's become kind of a big hurdle to reading
narrow.activate(), because it's out of chronological order
and it's hard to tell at a glance which variables it's closing
on.
Now we just move it out to module scope.
It's mostly moving code, with these minor changes:
* we pass in opts for the old closure vars
* we rename then_select_offset -> select_offset
* we early-exit on empty lists
We replace these variables in narrow.activate:
then_select_id (int w/-1 as a sentinel)
select_first_unread (boolean)
The main goal here is to get away from the boolean, since
we are about to introduce a third select strategy.
The new var is select_strategy and it has a union
type with these flavors:
"exact" (was select_first_unread === false)
"first_unread" (was select_first_unread === true)
The new flavor will be something like "last_id".
Eliminating then_select_id is also nice, since the -1
sentinel value could be a pitfall, and it's semantically
cleaner to encapsulate behind a check for
select_strategy.flavor.
We use an IIFE (immediately invoked function expression)
to fetch messages. This will allow us to introduce some
local vars in a subsequent commit without creating an ugly
diff and without cluttering an already crowded namespace.
