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. This commit pushes us towards that goal by simplifying
the future merge of the two CSS labels.
Currently the #tab_bar is just a container for the #tab_list and the
#tab_list handles the overflow attributes and so these do not serve
any purpose.

We have the same selector within #tab_list and the duplication is
unnecessary.
Ideally we would not be relying on something that requires a 4 line
comment, and also makes it harder to add more static elements at the
end of the navbar, but this block should be acceptable for now.
One alternate would be a "grow-1" class or similar but we might need
to think that through.
My previous message_header fix
0b4568d249
accidentally changed the alignment of dates in private messages (so that
it was inconsistent to the alignment in other narrows).
Previously .recipient_row_date was positioned absolutely, allowing it to
overlap with the topic name on narrow screens. This can be solved by
using flexbox. To implement the empty space between the bar controls and
the date on wider screens we move the date outside of the bar controls
(which also makes more sense semantically since the date isn't a
control).
Fixes#15501.
This fixes the bug of extra topics not being rendered on scrolling.
list_render uses `max-height` to determine which container is being
scrolled upon. Set the `max-height` on the scrolling container of
recent topics to help list_render identify it.
This particular commit has been a long time coming. For reference,
!avatar(email) was an undocumented syntax that simply rendered an
inline 50px avatar for a user in a message, essentially allowing
you to create a user pill like:
`!avatar(alice@example.com) Alice: hey!`
---
Reimplementation
If we decide to reimplement this or a similar feature in the future,
we could use something like `<avatar:userid>` syntax which is more
in line with creating links in markdown. Even then, it would not be
a good idea to add this instead of supporting inline images directly.
Since any usecases of such a syntax are in automation, we do not need
to make it userfriendly and something like the following is a better
implementation that doesn't need a custom syntax:
`![avatar for Alice](/avatar/1234?s=50) Alice: hey!`
---
History
We initially added this syntax back in 2012 and it was 'deprecated'
from the get go. Here's what the original commit had to say about
the new syntax:
> We'll use this internally for the commit bot. We might eventually
> disable it for external users.
We eventually did start using this for our github integrations in 2013
but since then, those integrations have been neglected in favor of
our GitHub webhooks which do not use this syntax.
When we copied `!gravatar` to add the `!avatar` syntax, we also noted
that we want to deprecate the `!gravatar` syntax entirely - in 2013!
Since then, we haven't advertised either of these syntaxes anywhere
in our docs, and the only two places where this syntax remains is
our game bots that could easily do without these, and the git commit
integration that we have deprecated anyway.
We do not have any evidence of someone asking about this syntax on
chat.zulip.org when developing an integration and rightfully so- only
the people who work on Zulip (and specifically, markdown) are likely
to stumble upon it and try it out.
This is also the only peice of code due to which we had to look up
emails -> userid mapping in our backend markdown. By removing this,
we entirely remove the backend markdown's dependency on user emails
to render messages.

When we extract common HTML template (`image_upload_widget.hbs` )
for user avatar, realm day/night logo and realm icon widget's
lot of new CSS are created to match image_upload_widget.hbs and
old CSS are preserved in `settings.scss`. This commit removes all
unwanted or unused CSS in `settings.scss`.
For the email and full name modals we simply change width to max-width.
The password modal used a flex-row class for no apparent reason,
the class wasn't used anywhere else and removing it fixes the UI bug.
Fixes#15311.
Fixes the click target for the gear icon by providing
a proper rectangular area around it.
Minor UI adjustments of gear icon and expanded
navbar-search for small size devices.
Fixes: #15222.
Since we had extracted `image_upload_widget.hbs` HTML for
image upload widget's like user avatar, realm logo, realm icon
we can also extract `image_upload_widget.scss` SCSS file
from settings.scss file with all the CSS related
to image upload widget's.
This change will also help us to keep `settings.scss` cleaner.
In zulip.yaml, add `deprecated` tags to all parameters/keys with
`Deprecated` in the description. Then add tests to ensure that deprecated
parameters/keys will always have the `deprecated` key. Also, in
the API docs, sort the parameters according to presence of `deprecated`
key, presenting the `deprecated` keys at the end and add a `deprecated`
tag next to them.
If your browser width was between 701px and 750px you got the mobile
view without the mobile header preventing you from changing sections in
the settings menu.
This was caused by a media-query mismatch:
subscriptions.scss used @media (max-width: 750px)
settings.scss however used @media (max-width: 700px)
Comments added by tabbott to help avoid future bugs like this.
* Don't annoyingly open the first section when switching
between the Settings and Organization tabs.
* Don't highlight currently active section in the settings list
(we don't display the currently active section in the mobile settings
list so it isn't actually active).
* Remove nearly invisible and buggy no-border logic.
The previous architecture did not work properly with the automatically
detected night theme, resulting in a weird mix of the night and day
themes on code blocks.
I'm not thrilled with the requirement this imposes that all of our
night theme CSS needs to be in one file, but we do need to get a quick
fix out here.
Fixes#15554.
Previously in desktop view, the realm day/night logo element is arranged
one by one which is not looking good since we have a lot of space on the
the right side of the logo elements so we can move day/night logo elements
to allow them being alongside.
In mobile view, we don't have any space on the right side of the logo
elements so we don't have to change anything.

Previously, the message controls had a bug where they would trigger on
mobile with a single tap over the area they occupy when visible. This
is wrong because a user would expect to first see the controls and
only trigger them once they are visible (with a second tap).
The above bug is caused by the fact that we were using "opacity: 0" on
".message_controls > div" to hide the controls and "opacity: 1" on
".messagebox &:hover .message_controls > div" to show the controls on
hover, however, this would not effect the click action because
"opacity". So we used "pointer-events: none;" and "pointer-events:
all;" with the hopes that it would prevented the above bug, but in
practice, it didn't.
(the most probable explanation being that tapping the message_control
area would cause the "&:hover" rule to trigger and change the
"pointer-event" to "all" before it could prevent the click trigger,
But that explanation is just conjecture.)
This commit replaces both "pointer-events" attributes with
"visibility: hidden" and "visibility: visible" respectively. The
result being that the message_controls behave identically to before,
except without the above bug.
The addition to the ".has_actions_popover .info" selector is important
because without it, we would regress on issue #3172.
Trivia:
An alternate approach to using "opacity" is to set the
"display" attribute to "none", however, using "display" prevents the
transition from animating (which is probably why we were using opacity
here in the first place). "visibility" does not prevent the transition
from animating.
History: The "pointer-events" attribute was introduced in
4d5aa3ddc9 and it replaced prior code
which relied on the "visibility" attribute... But it seems PR #3792
was mostly focused on improving the positioning through removal of
`display: none`, but introduced opacity to make the animations work
rather than visibility as the replacement solution, which requires the
pointer-events hack and resulted in the bug described here.
Fixes the second bug described in #13642.
With this implementation of the feature of the automatic theme
detection, we make the following changes in the backend, frontend and
documentation.
This replaces the previous night_mode boolean with an enum, with the
default value being to use the prefers-color-scheme feature of the
operating system to determine which theme to use.
Fixes: #14451.

With the previous color it was hard to read the text and
also that color does not matches with the zulip style.
This commit changes the color of `name` field for
user-profile modal for better visability both in day
and night mode.
The `.search_icon` lies inside the `.pill_container` so we had to
remove it's display attribute which should have no visual changes.
We add `flex-wrap: nowrap` to prevent the cursor from moving onto
a new line, below the pills.
Fixes#15480.
When we move the avatar upload widget to `image_upload_widget.hbs` file
the CSS `position:absolute` for `avatar-source` is preserved.
by removing CSS `position:absolute` we can fix the bug.
This commit adds frontend support for setting and updating message
retention days of a stream from stream settings.
Message retention days can be changed from stream privacy modal of the
stream and can be set from stream_creation_form while creating streams.
Only admins can create streams with message_retention_days value other
than realm_default.
This commit also contains relevant changes to docs.
Previously, we had implemented:
<span class="timestamp" data-timestamp="unix time">Original text</span>
The new syntax is:
<time timestamp="ISO 8601 string">Original text</time>
<span class="timestamp-error">Invalid time format: Original text</span>
Since python and JS interpretations of the ISO format are very
slightly different, we force both of them to drop milliseconds
and use 'Z' instead of '+00:00' to represent that the string is
in UTC. The resultant strings look like: 2011-04-11T10:20:30Z.
Fixes#15431.
This commits moves the css of upgrade-tip class from settings.scss
to app_components.scss as this class will also be used in stream
settings page for message-retention-days setting in further commits.
tip class in settings.scss is also moved as it has the same styles as
upgrade-tip class.
Now we can use common HTML image upload widget template
`image_upload_widget.hbs` for realm day/night logo and
we should access those day/night logo elements using
e.g., "#realm-day/night-logo-upload-widget .realm-logo-elements".
since we use image_upload_widget.hbs for realm day/night logo upload
widget we need to extract CSS for realm day/night logo and
place them separately under `#realm-day-logo-upload-widget`
and `#realm-day-logo-upload-widget` css id.
Now we can use common HTML image upload widget template
`image_upload_widget.hbs` for realm icon. we can access icon
element using "#realm-icon-upload-widget .realm-icon-elements".
also we need to extract CSS for realm icon and place them
separately under `#realm-icon-upload-widget` css id.
Previously, there was a small dead spot in the click area between the
sub_count and narrow_description, such that the mouse cursor would
switch from pointer to the default.
This commit corrects the dead spot by adjusting the margins and styles
on navbar elements.
This should be workable, but there is scope for improvement especially
given that the current margins and paddings are messy and not very
semantic.
The end result is that the entire navbar becomes a smooth, clickable
region.
Previously the click area to open the settings modal was limited to
just the stream name (just the text). This, inconveniently, created a
lot of empty, unclickable space around the stream name.
This commit resolves the problem by:
* Extracting the title and icon into a separate template as
`navbar_title_and_icon.hbs` and calls this partial in
`tab_bar.hbs`.
* Calling the partial within an <a> tag for stream based narrows
and in a <span> tag for non-stream narrows.
* Making some CSS changes so that everything still renders correctly
(visually).
This commit also:
* Leads us to "piggy back" all stream based narrow elements on the
`stream_settings_link` conditional. (Previously the only "piggy
backing" was by `narrow_description` on `sub_count`, which was
necessary for the rendering of the `(no description)` string.)
The end goal here is that the entire navbar is clickable. This is a
step towards that goal, but some of the margins on the sub count and
its ::before and ::after pseudo-elements still need to be fixed.
Previously the click area to open the settings modal was limited to
just the stream name (just the text).
A nice goal to strive for here is to make the entire navbar a
continuous clickable region.
This adds the same click action as `stream_name` to the `sub_count`.
There's still scope for improvement after this change because of the
margins on `sub_count::before` and `sub_count::after` as well as
because only the text in `stream_name` is clickable.
Currently the styles for the navbar are in a confusing and ugly state.
One of the problems is that we have several styles within the `span`
including some nested pseudotag selectors within the `span`.
This is bad because it gives semantic meaning to the `span` element
which we do not intend. We should remove as many styles which intend
to target "direct children" instead of "direct children that are
spans" and (iff there are styles for the later) then substitute the
"span" for a semantically meaningful class name.
Another problem here is that these pseudotag based selectors aren't
very clear and readable, which is something we can look into
correcting now that they are separate from the `span` tag.
This is a prep commit that aims to set us on the path for further
improvements. It also enables us to switch some tags around and allows
us to use the styles in the `span` block with other selectors via `,`.
This should make no visual or behavioral changes.
Google has removed the Google Hangouts brand, thus we are removing
them as video chat provider option.
This commit removes Google Hangouts integration and make a migration
that sets all realms that are using Hangouts as their video chat
provider to the default, jitsi.
With changes by tabbott to improve the overall video call documentation.
Fixes: #15298.
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.

Now we can remove `user-avatar-block` id and add common class `image_block`.
we can access this class using `#user-avatar-upload-widget .image_block`
so that we can have only one id at top-level and 'image_upload_widget.hbs`
can be more dynamic so we can use for other similar widgets also.
Now we can remove the id `avatar-spinner-background` and access spinner
element from `#user-avatar-upload-widget .image_upload_spinner` so
that we can have only one id at top-level and 'image_upload_widget.hbs` can
be more dynamic so we can use for other similar widgets also.
The upload text element is wrongly named as id=user_avatar_upload_button.
now we can remove that id and access upload text element from
`#user-avatar-upload-widget .settings-page-upload-text` so that we
can have only one id at top-level and 'image_upload_widget.hbs` can
be more dynamic so we can use for other similar widgets also.
We can remove id="user_avatar_delete" and access delete-text from
`#user-avatar-upload-widget .settings-page-delete-text` so that
we can have only one id at top-level and 'image_upload_widget.hbs`
can be more dynamic so we can use for other similar widgets also.
we can remove `user_avatar_delete_button` id and access delete button
from `#user-avatar-upload-widget .settings-page-delete-button` so that
we can have only one id at top level and 'image_upload_widget.hbs`
can be more dynamic so we can use for other similar widgets also.
Renaming "user-settings-avatar" to "image_upload_button" since the
`user-settings-avatar` name is irrelevant/confusing for the upload
button, and converting the id into a class so that we could just have
only one outer id.
We can check for the `is_editable_by_current_user` condition once in
the upper level instead of checking twice in middle for the same
conditions and to match the implementation of style realm icon and
realm logo since similar implementation between avatar, logo, the icon
will help us to use `image_upload_widget.hbs` for logo and icon
widgets also.
This likely fixes a bug with the delete text being shown incorrectly
for non-administrator users.
This changes the user avatar image display implementation to more
closely match how the realm icon and realm logo image features are
structured. This is early preparatory work towards sharing this code
between the various widgets.
The chevron sometime can be confused as an icon for expanding the
stream topics especially for the new users.
This commit replaces the confusing chevron icon from the stream-sidebar,
topic-list, user-presence-row, all-messages and starred-messages with
ellipsis-v icon(vertical three dots).
Fixes: #7115
The left simplebar sometime interferes with the
chevrons on the stream filters.
This commit reduces the width of active stream filter
by adding margin-right and hence fixes the overlap of
the simplebar over the active filters
This will adjust the height of user presence list elements to
match with the left-sidebar list elements i.e. 23px.
Extra margin is removed to avoid increase in too much spacing
between elements.
We reuse the existing logic for displaying and updating stream color
from the stream left sidebar.
Tests fixtures were extracted and updated for this commit.
* Add action to mute topics.
* We don't need to store muted data per topic as previously planned.
* Moved launch topic test to the top so that they run on non-modified
data.
* Show an empty overlay of recent topics.
* Register click event to open recent topics.
* Launch recent topics on "t" keypress.
This is based on the draft overlay.

This commit aligns the search icon in the navbar (with the search bar
closed) to be in the same position as the "search_exit" or "x" icon
(which appears when the search bar is open).
Commit c4e59309e4 introduced a
regression that caused a small part of the navbar in night mode to not
have the correct background color.
The relevant changes in that commit intended to fix the margin for the
search box for when the search pills feature was set to active.
This commit slightly increases the padding for the search box (when
pills are active), to improve pill alignment, and adds styles for
"#searchbox_legacy" to correct the background when search pills are
disabled.
This also reverts the change from commit
29b8e11e20 which tried to improve the
alignment of pills by adding a margin left but didn't address the
background color issue.
We now trigger realm day/night logo upload by clicking on realm
day/night logo element itself rather than having a big upload button
and to match our user avatar UI. Added new spinner over the logo
element itself to show while uploading realm logo for both day and
night logos.
Display logo at full width regardless of the size of the image to
reduce the dependency on the logo image in determining the logo
container size. This also fixes a problem owhere the night/day logos
would lose their default-dark/white background color when we upload an
image in jpg format rather than png.
Change user avatar spinner implementation to match
realm icon spinner implementation and have common css class
since similar implementation between similar widgets may help
in future deduplication.
This declaration already exists in the default CSS.
This declaration was present when the edit history modal was first
given a night mode (then called "dark mode") style in November 2017 in
4f81bdd0a6. It also existed in the
default CSS at that time.
Previously, topic edit diffs in the edit history modal were not
highlighted in the same way as content diffs because the highlighting
CSS rules were inside a .rendered_markdown block. So they affected the
content diffs, which are classed as such, but not the topic diffs.
This commit moves the highlight rules to a
.message_edit_history_content block inside the already existing
#message-edit-history block. .message_edit_history_content had
already existed in the edit history template message_edit_history.hbs,
and is assigned to both the content and topic diffs.
The ability to see topic edits in the edit history was added in
March 2019 in 38be5ea74394d2fd8586038de6ac447b4bbfbf67; the
highlighting worked at that time. It broke four mounths later in July
2019 in 38ffde37e5 when the highlight
rules were moved into a .rendered_markdown block after having been
global.
(As a further aside, .rendered_markdown was only added to the content
diffs in April 2019 in 5c36918c17.
.message_edit_history_content had been first added, to the content
diffs, in February 2019 in 7d42d7b4dbe6eb144a148135db50ad35efc01295.)
Aside from fixing topic edit diffs, this change is just more correct;
the highlight rules don't belong under .rendered_markdown, and they
don't need to be applied globally.
Option to disable breadcrumb messages were given in both message edit
form and topic edit stream popover.
User now has the option to select which stream to send the notification
of stream edit of a topic via checkboxes in the UI.
The commit fixes the spacing between the search icon and the input
field by adding `margin-left` to the search input field. The following
issue is only visible in dark mode as the nav and search input have
different background color while normal theme uses same background color
for nav and search input.
This isn't a complete fix, but we move the widget's popup to be
on/below the button to open the widget. We also move the bot owner
field to be on the top of the page so that we can see most of the
widget before it is clipped by the parent overlay.
We have discussed some approaches for a permanent fix on:
https://chat.zulip.org/#narrow/stream/321-s/topic/DropdownListWidget/near/894674
This reimplements our Zoom video call integration to use an OAuth
application. In addition to providing a cleaner setup experience,
especially on zulipchat.com where the server administrators can have
done the app registration already, it also fixes the limitation of the
previous integration that it could only have one call active at a time
when set up with typical Zoom API keys.

This commit changes the stream settings UI for adding subscribers to
use our standard user pills in the input box, rather than just
plain-text email addresses. This is important progress towards
removing display email addresses from the Zulip UI.
It also allows subscribing multiple users at the same time, which is a
nice improvement.
We remove the "GROUP PMs" section that used
to be in the lower right sidebar.
Most of this is straightforward code removal.
A couple quick notes:
- The message fetching code now just
calls `huddle_data.process_loaded_messages`,
which we still need for search suggestions.
We removed `activity.process_loaded_messages`.
- The `huddle_data.process_loaded_messages`
function no longer needs to return `need_resize`.
- In `resize.js` we now just calculate
`res.buddy_list_wrapper_max_height` directly
from `usable_height`.
The header is 40px tall, with a 10px gutter
below it, which means the top of our sidebars
are 50px from the top of the viewport.
Now all the places that share these values
use `$header_right` and related values.
This is pretty easy to test out by just doubling
or tripling the two numbers at the top of the
file.
The section for `@media (max-width: 500px)` seems
to have its own smaller values for things like
the `height` of `.header`, so I left it alone.
Trigger realm icon upload by clicking on realm icon element itself
rather than having a big upload button and to match our user avatar UI.
Added new spinner over the icon element itself to show while
uploading realm icon.
The bug this was working around does not affect our current toolchain,
as confirmed by grepping through the minified output.
(Also, this linter rule only matched calc(x + y) with two arguments
and we were already using calc($far_left_gutter_size + $left_col_size
+ 4px).)

The previous styling was brittle and ended up breaking in very small
phone-size views with the text overflowing the boundaries of the page.
The right fix is to move those heading outside the portico-header
class, since the CSS for that isn't generally appropriate here.
This is a prep commit which combines the previous `#searchbox`
block with the newly updated `#searchbox_legacy` block which
contains the modifications related to the new navbar display.
This only consists of changes to `#searchbox` and is still broken.
But it integrates the searchbox with the new tab_bar changes so that
only one searchbox is shown (instead of two, previously).
This fixes some issues with unclear terminology and visual styling in
the pages for the new free trial.
There's probably more we can and should usefully do in the future.
We already have a loading indicator for fetching older
messages. Thus it makes sense to implement the same
for displaying newer messages.
We set the display of `bottom-messages-logo` to none,
to prevent displaying two loading indicators during
the initial message load.
Fixes#15060.
`loading_more_messages_indicator` is renamed to
`loading_older_messages_indicator`.
This is a prep commit to introduce
`loading_newer_messages_indicator`.
This commit fixes the alignment of emoji in the navbar by removing a
redundant style which was breaking the emoji alignment.
This block is probably just a remanent from WIP development of this
version of the navbar & its inclusion on master was as an oversight.
Rather than showing the "Saving" widget beside stream name, it's more
intuitive to have it in personal settings section because it's the only
section which uses `settings_ui.do_settings_change` function and we follow
having a separate "Saving" widget for each section everywhere.
This code generates the timestamp string to be shown to the user
from the given timestamp in unix format using moment.js.
We also render the timestamp in a pill.
`margin-bottom` property is ignored due to the display.With
'display: inline', the width, height, margin-top, margin-bottom,and
float properties have no effect.
The currrent css of codeblocks left too much empty space between
the lines as well as indented the first character of a codeblock
slightly towards the right.
This commit fixes both of these, thus making codeblocks look closer
to what someone would expect codeblocks to look like in their text
editor.
We wrap the [reset] anchor tag in a button so that we can set 'disabled'
attribute on it. We change the styles to hide the [reset] button and the
pencil icon when the widget is disabled.
We also need to call `e.preventDefault()` in the event handler since now
the anchor tag behaves as a button.
Change in stream color occurs very rarely, and the palette is taking a lot of space in the popover.
This commit will hide the palette in default view of stream popover.
The navbar uses rendered markdown and rendered html within the narrow
description, this inserts eg katex--html and allows rendering of
inline math formulae. Unfortunately, in the previous SCSS file, this
fact was overlooked and a generic "span" selector was used with would
target all spans within the parent element, direct descendants or
otherwise, which caused the side effect of applying padding and margin
to inner katex elements which broke appearance.
This commit replaces the "span" selector with "& > span" so that only
spans which are the direct children to the parent element are selected
and katex--html is rendered correctly.
Fixes: #14947.
* Stream bar color logic is borrwoed from compose stream bar.
* Use flex containers to align elements and automatically set their
height to be same, them automatically filling the stream color bar
height to be the height of the select box.
* Use flex-wrap to wrap the propagate selector when out of space.
* To make sure stream select box and stream color box are closest possible,
select box has been moved under stream color box.
