Tags

Adds IRC v3 message tags to PRIVMSG and USERSTATE (if enabled with commands CAP)

PRIVMSG

Example message:

@color=#1E0ACC;display-name=3ventic;emotes=25:0-4,12-16/1902:6-10;subscriber=0;turbo=1;user-type=mod;user_type=mod :3ventic!3ventic@3ventic.tmi.twitch.tv PRIVMSG #notventic :Kappa Keepo Kappa
  • color is hexadecimal RGB color code, which can be empty if the user never set it.
  • display-name is the user's display name, escaped as described as described in the IRCv3 spec
  • emotes contains information to replace text in the message with the emote images and can be empty. The format is as follows:
    • emote_id:first_index-last_index,another_first-another-last/another_emote_id:first_index-last_index
    • emote_id is the number to use in this URL: http://static-cdn.jtvnw.net/emoticons/v1/:emote_id/:size (size is 1.0, 2.0 or 3.0)
    • Emote indexes are simply character indexes. \000ACTION does not count and indexing starts from the first character that is part of the user's "actual message". In the example message, the first Kappa (emote id 25) is from character 0 (K) to character 4 (a), and the other Kappa is from 12 to 16.
  • subscriberand turbo are either 0 or 1 depending on whether the user has sub or turbo badge or not.
  • user-type is either empty, mod, global_mod, admin or staff.

USERSTATE

USERSTATE is sent when joining a channel and every time you send a PRIVMSG to a channel. Example:

@color=#1E0ACC;display-name=3ventic;emote-sets=0,12239,2126,237,33,366,4578,469,793,9400;emotesets=0,12239,2126,237,33,366,4578,469,793,9400;subscriber=0;turbo=1;user-type=mod;user_type=mod :tmi.twitch.tv USERSTATE #gophergaming

The tags here work the same as in PRIVMSG, except some are missing. emote-sets contains your emote set, which you can use to request https://api.twitch.tv/kraken/chat/emoticon_images?emotesets=[straight from the emote-sets tag]. It should not be empty since 0 is the global emotes' emote set.
