This library contains character information about native emojis.
Add gemoji to your Gemfile.
gem 'gemoji'This would allow emojifying content such as: it's raining :cat:s and :dog:s!
See the Emoji cheat sheet for more examples.
module EmojiHelper
def emojify(content)
h(content).to_str.gsub(/:([\w+-]+):/) do |match|
if emoji = Emoji.find_by_alias($1)
%(<img alt="#$1" src="#{image_path("emoji/#{emoji.image_filename}")}" style="vertical-align:middle" width="20" height="20" />)
else
match
end
end.html_safe if content.present?
end
endTranslate emoji names to unicode and vice versa.
>> Emoji.find_by_alias("cat").raw
=> "π±" # Don't see a cat? That's U+1F431.
>> Emoji.find_by_unicode("\u{1f431}").name
=> "cat"You can add new emoji characters to the Emoji.all list:
emoji = Emoji.create("music") do |char|
char.add_alias "song"
char.add_unicode_alias "\u{266b}"
char.add_tag "notes"
end
emoji.name #=> "music"
emoji.raw #=> "β«"
emoji.image_filename #=> "unicode/266b.png"
# Creating custom emoji (no Unicode aliases):
emoji = Emoji.create("music") do |char|
char.add_tag "notes"
end
emoji.custom? #=> true
emoji.image_filename #=> "music.png"As you create new emoji, you must ensure that you also create and put the images
they reference by their image_filename to your assets directory.
You can customize image_filename with:
emoji = Emoji.create("music") do |char|
char.image_filename = "subdirectory/my_emoji.gif"
endFor existing emojis, you can edit the list of aliases or add new tags in an edit block:
emoji = Emoji.find_by_alias "musical_note"
Emoji.edit_emoji(emoji) do |char|
char.add_alias "music"
char.add_unicode_alias "\u{266b}"
char.add_tag "notes"
end
Emoji.find_by_alias "music" #=> emoji
Emoji.find_by_unicode "\u{266b}" #=> emoji
for the respective products. They should probably be dealt with the same as other extensions like 
. The same goes, of course, for any other "emojis" I'm not yet aware of.
