Adds a markdown preprocessor that finds ordered lists where all items
use the same number and change them to be in normal increasing order,
starting with that number.
Fixes#5159.
Hides URL if the message content == image url so that sending gifs or
images feels less cluttered. Uses the url_to_a() function to generate
the expected url string for matching.
Fixes#7324.
The character ">" now only starts a blockquote if the resulting
blockquote would be non-empty. Thus, by itself, ">" is now
interpreted literally by bugdown, fixing #687. The message
with contents consisting of ">>>" is now parsed as a doubly
(not triply) nested blockquote with contents ">". Properly
formed blockquotes have identical behavior as before, but now
bugdown can no longer produce empty blockquotes as output.
Fixes#2886, #687.
This commit helps reduce clutter on the navigation sidebar.
Creates new directories and moves relevant files into them.
Modifies index.rst, symlinks, and image paths accordingly.
This commit also enables expandable/collapsible navigation items,
renames files in docs/development and docs/production,
modifies /tools/test-documentation so that it overrides a theme setting,
Also updates links to other docs, file paths in the codebase that point
to developer documents, and files that should be excluded from lint tests.
Note that this commit does not update direct links to
zulip.readthedocs.io in the codebase; those will be resolved in an
upcoming follow-up commit (it'll be easier to verify all the links
once this is merged and ReadTheDocs is updated).
Fixes#5265.
While fixing an issue related to email gateway messages not getting
rendered properly, I unknowingly introduced a bug in the markdown
engine updation code. This commit fixes it. The issue was that for
a realm having email gateway setup, updation of realm filters would
lead to the updation of only one of the markdown engines not both.
The intended use of $$ is for inline expressions, not for multiline
ones; ```math is an acceptable alternative for the latter. Hence,
the $$-syntax for inline TeX no longer permits newlines within it.
This was also necessary for the next change to be sensible; namely
allowing for spaces around both $$ when crafting inline TeX instead of
forcing everything to be crammed together, e.g. $$x=7$$. In order to
avoid uninentionally creating inline expressions, the opening and
closing $$'s of an inline expression must now both exactly consist of
two dollar signs, no more and no less.
Fixes: #6488.
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.
The regex we were using didn't cover all the unicode blocks
to which our emojis belong. This commit fixes the regex to
include all the unicode blocks and also updates the
corresponding JS regex in marked.js.
Fixes: #3460.
Unicode codepoints are of minimum length 4, padded with extra
zeroes if the length is less than 4. This commit fixes the
`unicode_emoji_to_codepoint()` to ensure that the codepoint
it generates are of correct length.
- Add file_name field to `RealmEmoji` model and migration.
- Add emoji upload supporting to Upload backends.
- Add uploaded file processing to emoji views.
- Use emoji source url as based for display url.
- Change emoji form for image uploading.
- Fix back-end tests.
- Fix front-end tests.
- Add tests for emoji uploading.
Fixes#1134
Earlier, a stack was being used to go through the message and search
for links. Because of this, in some cases the images were added to
the preview in reverse. Using a queue will keep the image previews in
the same order as they appeared in the message.
Fixes#4453.
By default, Python markdown tab length for indents is 4 spaces, which
require using 4 spaces or a tab to create nested elements. This
modifies that setting to specify 2-space indentation for nesting
elements only.
Modified significantly by tabbott to limit the change to just list
indentation.
Fixes#4252.
Use `name_to_codepoint.json` file (and the similar structure in
emoji_codes.js) to map emoji names directly to codepoints and change
the rendered emoji image to `unicode/<codepoint.png>` rather than
`<emoji_name>.png`.
Fixes: #3539.
We do not use `get_link_embed_data` for messsages sent by
bots, as bots often repeat the same URL over and over again
and are generally either text-focused or have their own
mechanisms to provide preview content.
Fixes#2968.
(The commit q7ef4e40258280e202325c9295579c93fb948b replaced
data-user-email with data-user-id, but we still need to
support data-user-email for old clients like non-updated
androids and we still want to start the migration forward
to data-user-id.)
This changes bugdown to use the realm passed in by the caller (if any)
for rendering, fixing a problem where bots such as the notification
bot would have their messages rendering using the admin realm's
settings, not the settings of the realm their messages are being sent
into.
Also adds a test for the notification bot case.
Fixes#3215.
A lot of care has been taken to ensure we're using the realm that the
message is being sent into, not the realm of the sender, to correctly
handle the logic for cross-realm bot users such as the notifications
bot.
This should substantially improve the clarity of the code, since
inside bugdown, this is only being used as a hash key that happens to
usually be a realm ID, not used as a Realm ID.
This change adds support for displaying inline open graph previews for
links posted into Zulip.
It is designed to interact correctly with message editing.
This adds the new settings.INLINE_URL_EMBED_PREVIEW setting to control
whether this feature is enabled.
By default, this setting is currently disabled, so that we can burn it
in for a bit before it impacts users more broadly.
Eventually, we may want to make this manageable via a (set of?)
per-realm settings. E.g. I can imagine a realm wanting to be able to
enable/disable it for certain URLs.
Now that we have updated python-markdown, we remove the deprecated
safe_mode. We used safe_mode to escape raw html, so now instead we
pass in an EscapeHtml markdown extension to the markdown engine.
See https://pythonhosted.org/Markdown/release-2.6.html for details on
the deprecation.
Fixes: #2037 (also addresses the remaining piece of #2043).
This distinguishes between YouTube Videos and Image Previews by adding
a particular “youtube-video” class to the preview along with changing
the title to the video ID rather than the link. This serves to allow
the lightbox to ID when a lightbox preview should be treated like a
YouTube video rather than an image preview.
This also modifies the tests in bug down to expect a youtube-video class
along with the title to just be the video ID on YouTube rather than the
entire URL link.
The changes that required us to fork this extension had been merged
into upstream CodeHilite, so we can remove it and switch to using the
version that comes with python-markdown.
This updates Bugdown to reflect the changes in the updated
markdown. In particular, we now pass a default config object in the
__init__ for the Bugdown extension, update the make_md_engine function
to take kwargs as opposed to a config list, and have UListProcessor
inherit from ulist as opposed to olist (which no longer works).
We update the (forked from upstream) fenced_code extension's
makeExtension to take args and kwargs, and update
FencedBlockPreprocessor __init__ method with updated Codehilite
arguments.
We update the (forked from upstream) Codehilite extension to
mirror the logic with the latest upstream Codehilite:
Add parse_hl_lines function
update makeExtension to take args and kwarfs instead of config
list
Add regex for highlight lines
use linenums instead of linenos
use get_formatter_by_name instead of HtmlFormatter
user get_lexer_by_name instead of TextLexer
add hl_lines and use_pygments arguments to the codehlite
constructor
