Installation

gem 'gemojifyjs'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gemojifyjs

Usage

This method should only accept plain text, do not pass it html as it could break links and escape characters e.g. &don't do this would break the escape sequence. If you to use it with html or anchors rather remove them first and add them back in. This is sufficient for my use:

emoji: (text) ->
    cache_anchors = text.match(/<a [^<]+<\/a>/g) or []
    for anchor in cache_anchors
      text = text.replace(anchor, '<a>')
    cache_escapes = text.match(/\&(#[0-9]+)|[a-zA-Z]+;/g) or []
    for escape in cache_escapes
      text = text.replace(escape, '<e>')
    text = emojify.markup(text)
    for escape in cache_escapes
      text = text.replace('<e>', escape)
    for anchor in cache_anchors
      text = text.replace('<a>', anchor)
    return text
}
