Nick is the part part leading up to the exclamation point. In your example it’s “comcool”. Most IRC libraries will parse it out for you. If you are not using a library you’ll have to parse it manually.

Like @george pointed out, the `nick` of a user is the text leading up to the exclamation point. To give a little more detail on the structure, turn to the RFC 1459 [spec](https://tools.ietf.org/html/rfc1459.html#section-2.3.1).

The `nick` is located within the `prefix`, if one exists. The general structure being:

```auto
<server_or_nick>!<user>@<host>

```

When a prefix is present, the `<server_or_nick>`is always included, where as both the `<user>` and `<host>` are optional and may not be present. If `<user>` is included it will be prefixed by `!`, and if `<host>` is included it will be prefixed with `@`. In the case of Twitch and ingesting chat messages, I’ve always seen the full prefix included in the message.

On a side note, is the data you posted the _exact_ data that was ingested? Because the prefix, command, and parameters look malformed.

Hm, Twitch must have updated their prefix format. Regardless, the information you want is the data between the colon and the exclamation point.
