This commit moves the `emoji_collection` datasource in the emoji
picker to emoji.js and renames it to `emojis_by_name`. It is a
mapping from emoji name to object where each object describes an
emoji. This is an effort in the direction of de-duplicating and
unifying the datasets being used by various our widgets(like
emoji picker and composebox typeahead) in the webapp. Migrating
all the widgets to a single datasource will help us in removing
the whole class of annoying bugs which causes some emojis to be
missing from some widgets.
This commit updates the `emoji-datasource` packages to version 4.0.4.
This update brings following changes to emoji infra:
1: Fix for the bleeding sprite sheets.
2: The category of some emojis has been changed. Categorywise breakup of
net gain or loss is as follows:
Travel & Places: 58 (gain)
Symbols: 47 (loss)
Smileys & People: 52 (gain)
Objects: 11 (loss)
Food & Drink: 3 (gain)
Animals and Nature: 46 (gain)
Activities: 9 (loss)
3: There were some changes in the image farm of the package which were
breaking our old emoji farm. I fixed them by modifying the remapped
emoji map.
Fixes: #8235.
This migrates Zulip to use a dramatically better set of names and
aliases for our emoji set, defined in emoji_names.py (which is in turn
manually generated from our hand-curated CSV file).
This should significantly improve the experience of using Zulip's
emoji picker and emoji typeahead for finding what one is looking for.
This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests. (The latter goal has some
complications, since we often intentionally leak
setup in tests.)
Emojis which are represented by a sequence of codepoints or emojis
with ZWJ are not included until we implement a mechanism for dealing
with their unicode versions.
Fixes: #6279.
