Class EmojiProcessor

java.lang.Object
tv.phantombot.scripts.handler.EmojiProcessor
public class EmojiProcessor extends Object
This is a helper class to parse emojis. Rhino does not support the y-flag for RegExp which is needed to run Twitter's twemoji-parser. It runs, but it causes an infinitive loop because the lastIndex variable is not behaving as expected and therefore the abort condition will never happen. This implementation relies on emoji-java. It just uses the emoji parser and the emoji database (as of version 5.1.1 it's Emoji Version 13.1). The output are codepoints that are compatible with the common emoji libraries such es Twemoji.
