Generally emails are not written with markdown in mind and hence
sometimes render in strange ways. This commit fixes a particular
issue that was causing whitespace before paragraphs to be treated
as code block due to which email content was being rendered in a
box that scrolls in right direction a lot.
Fixes: #7045.
This adds the data model and bugdown support for the new UserGroup
mention feature.
Before it'll be fully operational, we'll still need:
* A backend API for making these.
* A UI for interacting with that API.
* Typeahead on the frontend.
* CSS to make them look pretty and see who's in them.
We now have a MentionData class that encapsulates
the users who are possibly mentioned in a message.
Not that the rendering code may not keep all the mentions,
since things like backticks will suppress the mention.
We populate this now in do_send_messages, so that we can use
the info earlier in the message-sending process. This info
now gets passed down the call stack as an optional parameter.
Note that bugdown.convert() still populates the data when its
callers decline to pass in a MentionData object.
This is mostly a preparatory commit, as we don't take advantage
of the data yet in do_send_messages.
Nobody has used this feature in years, and it causes certain types of
markdown issues in development to completely DoS the development
environment by making it possible for the "Bugdown timeout" exception
handler to timeout in bugdown.
Since we already send an email to the server administrators, there's
no need to replace this feature with anything.
This commit switches to use sprite sheets for rendering emojis
in all the remaining places, i.e., message bodies and composebox
typeahead. This commit also includes some changes to notifications.py
file so that the spans used for rendering emojis can be converted
to corresponding image tags so that we don't break the emoji rendering
in missed message emails since we can't use sprite sheets there.
As part of switching the bugdown system to use sprite sheets, we need
to switch the name_to_codepoint mappings to match the new sprite
sheets. This has the side effect of fixing a bunch of emoji like
numbers and flag emoji in the emoji pickers.
Fixes: #3895.
Fixes: #3972.
We now triage message content for possible mentions before
going to the cache/DB to get name info. This will create an
extra data hop for messages with mentions, but it will save
a fairly expensive cache lookup for most messages. (This will
be especially helpful for large realms.)
[Note that we need a subsequent commit to actually make the speedup
happen here, since avatars also cause us to look up all users in
the realm.]
Given typeahed and the fact that this only worked if the person had a
full name that didn't contain whitespace, this side effect of the
original @shortname mentionfeature that we removed was experienced by
users as a bug.
Fixes#6142.
Process the unicode emojis in twitter link previews and render them
properly. Before this we were not processing the unicode emojis in
twitter link previews and hence on the systems which don't have
fonts for displaying them they were rendered as blank boxes.
Fixes: #5427.
This commit renames list named `to_linkify` in twitter link processor
to `to_process` and adds a `type` field to each entry in it to
indicate the type of data represented by that particular entry.
Unicode emojis when rendered should display canonical short name.
Similarly, the alt text should be of the format `:<short_name>:`.
For both of these we currently display the actual unicode symbol.
As some systems don't have the fonts necessary for displaying them
properly, they are rendered as empty square blocks. This commit also
ensures that the markup generated for emoji generated by canonical
name and by an unicode emoji is same.
Fixes: #5555.
We used shortnames for mentioning users before we had autocomplete
feature. Since we now have autocomplete typeahead, this syntax is
no more useful and just causes problems. This commit removes the
shortname mention syntax.
Fixes: #4189.
A deactivated realm emoji should neither be accepted further as a
reaction nor its further occurences in a message be rendered as an
emoji. However, all the old occurences should continue to render
normally.
The `data-toggle` property prevented the new style of overlay modals
from launching, and regardless, isn't a future-proof options for how
this should work.
