Emojis

Since Whisperfish beta.1 or dev-b1143, Whisperfish supports colored emoji.

Tl;dr

Whisperfish supports different emoji styles. Download a set and extract it to:

~/.local/share/sailor-emoji/

Sets supported by default:

OpenMoji:

download the latest SVG package
extract it to ~/.local/share/sailor-emoji/openmoji/13.0.0
run for i in *.svg; do mv -v "$i" $(echo $i | tr '[:upper:]' '[:lower:]'); done (in bash) to convert all names to lower case

cd /tmp
curl -LJO https://github.com/hfg-gmuend/openmoji/releases/download/13.0.0/openmoji-svg-color.zip
mkdir -p ~/.local/share/sailor-emoji/openmoji/13.0.0
unzip openmoji-svg-color.zip -d ~/.local/share/sailor-emoji/openmoji/13.0.0
cd ~/.local/share/sailor-emoji/openmoji/13.0.0
for i in *.svg; do mv -v "$i" $(echo $i | tr '[:upper:]' '[:lower:]'); done

And then restart Whisperfish.

Twemoji:
- download the latest full package
- extract assets/svg/ to ~/.local/share/sailor-emoji/twemoji/13.0.1
Whatsapp: you have to fetch PNG files in multiple resolutions from Emojipedia (see below for details)

Details

Whisperfish supports different emoji styles. They have to be installed in:

~/.local/share/sailor-emoji/

Currently, all styles have to be registered in qml/js/emoji.js. This can be simplified in the future.

Emoji sets are folders of emoji icons in either a vector or raster format (svg is preferred). Each emoji icon must be named <codepoint>.<ext> (lower case), combined codepoints are separated by -. Some emojis may include the "emoji style" selector (uFE0F); it is recommended to create symbolic links for the version with and without the selector.

Raster emojis must be available in the sizes 72x72px and 144x144px.
