Extracting the function makes it a bit easier to
test and use in a generic way.
Also, I wanted this to live in stream_data, so that
it's easier to find if we change how we model
subscriber data.
Finally, I use _.every to do the subset check
instead of `_.difference`, since _.difference
is actually N-squared:
_.difference = restArguments(function(array, rest) {
rest = flatten(rest, true, true);
return _.filter(array, function(value){
return !_.contains(rest, value);
});
});
And we don't actually want to build a list only
to check that it's zero vs. nonzero length.
We now do this, which short circuits as soon
as it finds any key that is only in sub1:
return _.every(sub1.subscribers.keys(), (key) => {
return sub2_set.has(key);
});
First, there are no more convoluted signals.
We also simplify the parameter to just the "mentioned"
object corresponding to either a user or a broadcast
mention.
For the user group scenario, this has always been dead
code, which you only realized when you got to the comment
at the bottom. Now we actually do nothing.
And I moved the relevant commment to the
the typeahead code (with new wording).
I also moved the is_silent check to the caller. I don't
feel too strongly about that either way. It's kind of silly
to call a function only to give that function an additional
responsibility to worry about. On the other hand, I see
the logic of that function enforcing everything. I went
with the former for now.
Arguably we should have a warning for silent mentions,
since doing a silent mention of somebody not on a stream
is a good indication of a typo. I do understand the use
case, but the user can always ignore the warning. Anyway,
we have decent test coverage on this.
This isn't really an extraction; it's more giving
a name to an anonymous function and moving it to
higher module scope.
We convert this to an ordinary function call, which
allows us to move it out of intialize().
Since there's just one simple parameter now (linked_stream),
we can avoid some error checking.
We also avoid the comment that describes the function,
since it now has a name.
And then one minor tweak is to do the inexpensive
`invite_only` higher in the function. This will be
a nice speedup when you link to really large public
streams.
The unit tests are also a bit easier to read now--less
setup and more explicit names.
This experimental setting disables sending private messages in Zulip
in a crude way (i.e. users get an error when they try to send one).
It makes no effort to adjust the UI to avoid advertising the idea of
sending private messages.
Fixes#6617.
If a message begins with /me, we do not have any cases where the
rendered content would not begin with `<p>/me`. Thus, we can safely
remove the redundant checks both on the backend and frontend.
The compose_state.recipient field was only actually the recipient for
the message if it was a private_message_recipient (in the sense of
other code); we store the stream in compose_state.stream instead.
As a result, the name was quite confusing, resulting in the
possibility of problematic correctness bugs where code assumes this
field has a valid value for stream messages. Fix this by changing it
to compose_state.private_message_recipient for clarity.
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.

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.

If we complete a typeahead with an invalid stream name in composebox,
we would get 'compose_stream is undefined' error while running the
checks to prevent accidentally mentioning private streams.
We can safely early-return from this function and let the 'send'
event handler show the error to the user.
Right now we have buttons for "New conversation" and "New private message"
in different views, but both buttons do the same thing.
The current state is confusing for new users, since there is already a lot
of terminology one needs to learn in order to understand the Zulip
conversation model. It's very plausible a user would think a "conversation"
is something different from a "private message" or a "topic".
This changes the "new private message" button to be instead "new
conversation" when looking at PMs, to avoid confusion that the button
was the right thing to do to reply to the current private message
conversation.
Fixes#11679.
This adds a function that controls the whole process of applying
markdown and displaying the markdown rendering preview on request;
This is required to avoid code duplication when adding preview feature
to message-edit UI.
This code will correctly add video call link to the message
textarea based on whether 'Add video call' was selected from
message composition form or message edit form.
The implementation was semi-rewritten by tabbott to remove an
unnecessary global variable, with fixes for the unit tests from
showell.
Fixes#11188.
Previously, messages with more than one line did not parse '/me' at
the beginning of the message. Since there's a reasonable way to
render multi-line messages, this commit adds support for doing so.
This change does potentially break with the expected behavior of other
slash commands, but it seems worth providing useful functionality over
a blind focus on consistency.
Fixes#11025.
The stream/topic edit areas now have these ids:
#stream_message_recipient_stream
#stream_message_recipient_topic
They are pretty verbose, but being able to grep
for these without noise does have some value.
Fixes#10124.
Users in the waiting period category cannot subscribe other users to
a stream. When a user tries to mention another unsubscribed user, a
warning message appears with a subscribe button on it to subscribe
the other user.
This commit removes the subscribe button and changes the warning text
for users in the waiting period category.
Instead of displaying a fixed error message inside the yellow bar itself,
now the yellow bar disappears on error and a red compose_error is shown.
The error message is the one returned from the server.
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.
We can now theoretically use this for any textarea
that supports our markdown (besides the compose box),
plus we keep the RTL code a bit more self-contained.
This implements right-to-left message automatic detection support in
the compose box as well as the message feed. Full unit tests and
support in the message-editing UI are for future work (as are
potentially more fancy things like supporting things like
right-to-left multi-word names for users/streams/etc.).
Fixes#3123.
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.
This adds a /ping command that will be useful for users
to see what the round trip to the Zulip server is (including
only a tiny bit of actual server time to basically give a
200).
It also introduce the "/zcommand" endpoint and zcommand.js
module.
