We add this API to emoji.js, so that markdown
doesn't need to look at internal data structures
(or even need to understand any kind of record
format for results).
Here are the functions:
get_realm_emoji_url()
get_emoji_name()
get_emoji_codepoint()
We use the API now in markdown, which eliminates
the need for the markdown parser to require
the emoji JSON file.
Each function has a simple docstring:
get_emoji_name('1f384') === 'holiday_tree'
get_emoji_codepoint('avocado') === '1f951'
get_realm_emoji_url('shrug') === '/user_avatars/2/emoji/images/31.png'
Also we have simple test coverage for the API
(including tests that verify the docstrings).
This name was misleading, because we weren't
actually setting realm_filters (that's what
`page_params.realm_filters = realm_filters`
is for); we were instead updating our
realm filter rules.
We are gonna phase out util.get_message_topic()
in our entire codebase eventually, but we
certainly don't need it here, since the local
echo codepath is using brand new objects that
we construct inside the compose code, and
there's no danger of legacy "subject" data.
My goal for the markdown code is to keep it
free of any accidental dependencies that we
can easily avoid, as I think there's some
possible future where we split out the code
as its own library for people who want to
render Zulip markdown in non-core projects.
These functions were just shims that were
used in the somewhat painful migration from
subject_* to topic_*.
The commit 4572be8c27
fixed it so that the client never needs to
deal with "subject_links".
So now we just go back to simpler code:
message.topic_links = links
links = message.topic_links
We now handle the all/everyone/stream case at
the top of userMentionHandler.
Previously the code would do strange things
in the case that some user had the name "all"
or "everyone" or "stream". It would only
affect local echo, and maybe we prevent users
from having those names, so I doubt there
were any real user-facing issues here.
But the new code is clearly more simple and
more correct.
Most of this logic is specific to markdown
message processing, so we move the code to
markdown.js.
The only responsibility that we leave with
`emoji.js` is to provide us with a list
of translations (regex and replacement text).
But now `markdown.js` actually (directly) executes
those translations against Zulip messages
as part of its preprocessing.
This should simplify the upcoming mobile conversion.
Instead of mobile needing to duplicate this fairly
complex function, they will just need to pass
us in a list similar to `emoji_translations` inside
of `emoji.js`. That code has a comment that shows
what the data structure looks like.
We now treat util like a leaf module and
use "require" to import it everywhere it's used.
An earlier version of this commit moved
util into our "shared" library, but we
decided to wait on that. Once we're ready
to do that, we should only need to do a
simple search/replace on various
require/zrequire statements plus a small
tweak to one of the custom linter checks.
It turns out we don't really need util.js
for our most immediate code-sharing goal,
which is to reuse our markdown code on
mobile. There's a little bit of cleanup
still remaining to break the dependency,
but it's minor.
The util module still calls the global
blueslip module in one place, but that
code is about to be removed in the next
few commits.
I am pretty confident that once we start
sharing things like the typeahead code
more aggressively, we'll start having
dependencies on util. The module is barely
more than 300 lines long, so we'll probably
just move the whole thing into shared
rather than break it apart. Also, we
can continue to nibble away at the
cruftier parts of the module.
webpack optimizes JSON modules using JSON.parse("{…}"), which is
faster than the normal JavaScript parser.
Update the backend to use emoji_codes.json too instead of the three
separate JSON files.

Using startsWith is faster than indexOf, especially for long strings
and short prefixes. It's also a lot more readable. The only reason
we weren't using it was when a lot of the code was originally written,
it wasn't available.
This required lots of manual testing:
- search/navigate user presence
- send PM and mention user
- pay attention to compose fade
- send stream msg and mention user
- open Private Messages in top-left and click
- test unread counts
- invite user who already has account
- search for users in search bar
- check user settings
- User Groups
- Users
- Deactivated Users
- Bots
- create a bot
- mention user groups
- send group PM then click on lower right
- view/edit/create streams
If there are still pieces of code that don't convert
ids to ints, the code should still work but report
blueslip errors.
I try to mostly convert user_ids to ints in the callers,
since often the callers are dealing with small amounts
of data, like user ids from huddles.
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.
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.

This brings us in line, and also allows us to style these more like
unordered lists, which is visually more appealing.
On the backend, we now use the default list blockprocessor + sane list
extension of python-markdown to get proper list markup; on the
frontend, we mostly return to upstream's code as they have followed
CommonMark on this issue.
Using <ol> here necessarily removes the behaviour of not renumbering
on lists written like 3, 4, 7; hopefully users will be OK with the
change.
Fixes#12822.
Our implementation requires at least 1 space after the
'#' not not break existing linkifiers like '#123', etc.
that generally follow the convention we show in linkifier
examples.
- [valid] : # Hello
- [valid] : # Hello
- [invalid]: #Hello
For the frontend, we have taken the code from v0.7.0 of
upstream marked and made minor changes to avoid having
to refactor a significant part of our marked code.
For the backend, we merely have to change the regex to
force require spaces after #, and add hashheader to our
list of blockparsers.
Fixes#11418.
We reuse the link regexes we use elsewhere inn markdown
for parsing links in topic names and add a button to open
them in new tabs similar to our behavior with linkifiers
in topic names.
Fixes#12391.
This fixes an issue where blank lines between blocks were causing
auto-numbering of list to stop before the blank line resulting
in two separate numbered list instead of one.
Edited significantly by tabbott to explain the tricky details in the
comments.
Fixes: #11651.
For consistency, we should keep all the code that works with
@mentions in markdown.js. In this case, message_list_view was
rewriting the contents of the mentions in cases where users'
names had been changed since we rendered their mention.
This change should help people discover to distinguish
silent mentions in text as a part of Zulip syntax while
differentiating them from regular mentions.
We swallow the error if our python_to_js_filter code is
unable to parse some python regex properly. This ensures
that the web app stays responsive.
We would fail to show an accurate local echo for these
regexes, however, the backend would act as the final
authority for handling the realm pattern conversion.
Since on replacing the first 'P<>' group, we remove this text from
the string, we have to make the RegExp start looking from index 0
again to properly convert later 'P<>' groups to JS regex syntax.
On the backend, we extend the BlockQuoteProcessor's clean function that
just removes '>' from the start of each line to convert each mention to
have the silent mention syntax, before UserMentionPattern is invoked.
The frontend, however, has an edge case where if you are mentioned in
some message and you quote it while having mentioned yourself above
the quoted message, you wouldn't see the red highlight till we get the
final rendered message from the backend.
This is such a subtle glitch that it's likely not worth worrying about.
Fixes#8025.
These mentions look like regular mentions except they do not
trigger any notification for the person mentioned. These are
primarily to be used when you make a bot take an action and
the bot mentions you, or when you quote a message that mentions
you.
Fixes#11221.
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.
For message groups, I just changed the internal name
to "topic_links".
For uses of "subject_links" that are tied to how the
server names fields, I introduced these wrappers:
* util.set_topic_links(obj, topic_links)
* util.get_topic_links(obj)
These can be used for either messages or events.
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 is preparation for enabling an eslint indentation configuration.
90% of these changes are just fixes for indentation errors that have
snuck into the codebase over the years; the others are more
significant reformatting to make eslint happy (that are not otherwise
actually improvements).
The one area that we do not attempt to work on here is the
"switch/case" indentation.
