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.
Replaces the hardcoded list of emoji_names and unicode_emoji_names in
static/js/emoji.js with a list generated from emoji_map.json, both to get
the list out of version control and so we can start modifying it for our
autocomplete. This does not change the contents of emoji_names. It sorts and
removes duplicates from unicode_emoji_names (causes no change in behavior,
since unicode_emoji_names is only used as if it were a set).
This commit replaces the placeholder "clipboard" button with a reaction button.
This is done on any message that can't be edited. Also, on messages sent by
the user the actions popover (toggled by the down chevron icon) contains
an option to add a reaction.
When clicked, a popover with a search bar and a list of emojis is displayed.
If the right sidebar is collapsed (the viewport is small), the popover is placed
to the left of the button.
Focus is set to the search bar. Typing in the search bar filters emojis.
Emojis with which the user has reacted to this message are highlighted.
Clicking them sends an API request to remove that reaction.
Clicking on non-highlighted emojis sends an API request to add a reaction.
When the popover loses focus it is closed.
The frontend listens for reaction events. When an add-reaction event is
received, the emoji is displayed at the bottom of the message with a
count initialized to 1. If there was an existing reaction to the message with
the same emoji, the count is incremented.
Old messages fetched from the server contain reactions.
They are displayed (along with title and count) at the bottom
of each message.
When clicking the emoji reaction at the bottom of the message, if the
user has already reacted with that emoji to this message, the reaction
is removed and the count is decremented. Otherwise, a reaction is added
and the count is incremented.
Hovering over the emoji reaction at the bottom of the message displays
a list of users who have reacted with this emoji along with the
emoji name.
Hovering over the emoji reactions at the bottom of the message displays
a button to add a reaction.
Fixes#541.
- Expand a box full of emojis into the
compose window for users to graphically select emojis.
- Append an emoji to the end of the message when a user
clicks the emoji in the emoji box.
- Trap the escape key to always close the emoji box
before closing anything else if the box is open.
- Fixes: #147.
`glue` ingores the + sign in the name of the emoji and creates the css
class without it. This causes the emoji pallete to miss '+1'
emoji. This commit creates a translation map from emoji name to css
class that we can use for the emoji popover.
In a few cases the $.each was doing something imperatively that was
terser and easier to understand by using a different Underscore method,
so a few of these I rewrote.
Some code was using the fact that jQuery sets `this` in the callback to
be the item; I rewrote those to use an explicit parameter.
Some code was using $(some selector).each(callback). I converted these
to _.each($(some selector), callback).
One function, ui.process_condensing, was written to be a jQuery $.each
callback despite being in a totally different module from code using it.
I noticed this and updated the function's args.
