Extend our markdown system to support mentioning of users
by id also. Following these changes, it would be possible
to mention users with @**|user_id** and silently mention
using @_**|user_id**.
Main intention for extending the mention syntax is to make
it convenient for bots to mention a users using their ids. It
is to be noted that previous syntax are also supported.
Documentation tweaked by tabbott for better readability.
The changes were tested manually in development server, and also
by adding some new backend and frontend tests.
Fixes: #17487.
Modifies `StreamPattern` and `StreamTopicPattern` to inherit
from InlineProcessor instead of Pattern. This change is done
because Pattern stopped checking for matching patterns as soon
as it found a match which was not a valid stream. Due to this
all the subsequent mention failed, even if they were valid.
This bug was only present in backend renderring due to
markdown.inlinepatterns.Pattern.
Due to above changes verbose_compile is no longer used for
precompiling STREAM_LINK_REGEX, STREAM_TOPIC_LINK_REGEX as
adds ^(.*?) and (.*?)$ which cause extra overhead of matching
pattern which is not required. With new InlineProcessor these
extra patterns at beggining and end are not required.
So, StreamPattern and StreamTopicPattern now define their own
__init__ method for precompiling the regex.
Fixes#17535.

Modifies `UserGroupMentionPattern` to inherit from InlineProcessor
instead of Pattern. This change is done because Pattern
stopped checking for matching patterns as soon as it found
a match which was not a valid user group. Due to this all
the subsequent user group mention failed, even if they were

Initally, when writing two or more quotes, having
a blank line in between them, merges those quotes.
This created confusion especially in "quote and reply".
This commit fixes such issues. Now two or more quotes
having a blank line in between them, will not get merged.
This change is correct both for usability and for improving our
compatibility with CommonMark.
Fixes#14379.
Upstream has slightly changed the whitespace around stashes. Take
this opportunity to clean up the extra blank lines we were outputting.

If multiple filters match the same string, we run into an infinite
loop of converting string into urls. To fix it, we mark the matched
string as atomic after first conversion.
When converting fenced code markdown, we add the language (if specified)
in a data-attribute by tweaking the HTML generated. Doing so, allows the
frontend to make use of this attr to display view-in-playground option
for codeblocks.
We use pygments to get the lexer subclass name and use that instead of
directly using the language in the data-attribute. Doing so, helps us
map different language aliases (like `js` and `javascript`) into a common
variable (like `JavaScript`) - and avoids the client from dealing with
multiple tags corresponding to the same language.
The html structure for a message like this:
``` js
..content..
```
would now be:
<div class="codehilite" data-codehilite-language="JavaScript">
<pre>..content..</pre>
</div>
Tests and fixtures amended.
This change makes our handling of youtube-url previews consistent
with how we handle our inline images. This allows the previews to
render next to the paragraph that links to the youtube video.
Follow-up to PR #15773.
A few major themes here:
- We remove short_name from UserProfile
and add the appropriate migration.
- We remove short_name from various
cache-related lists of fields.
- We allow import tools to continue to
write short_name to their export files,
and then we simply ignore the field
at import time.
- We change functions like do_create_user,
create_user_profile, etc.
- We keep short_name in the /json/bots
API. (It actually gets turned into
an email.)
- We don't modify our LDAP code much
here.
Previously, we rendered the twitter previews outside of a
spoiler block at the end of the message. The commit series
ending with this commit fixes that by inlining twitter
previews instead of appending them all at the end. As a
consequence of the inlining, we have fixed the issue here.
This commit just adds a test to assert that.
Fixes#15518.
This is similar to our behavior with image previews, and helps
reduce clutter in the final rendered html.
We add the string 'Tweet: ' to our existing tests so those tests
remain the same.
This commit makes our handling of twitter previews consistent with
how we handle our inline images so that tweets render next to the
paragraph that links to the tweet.
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.

Prior to this commit whenever convert was imported from zerver.lib.markdown
it was aliased as markdown_convert for readability.
This commit rename convert function to markdown_convert so that it can be
directly import it without aliasing and without compromising readability.
