Function formatMessage

formatMessage(
    msg: {
        command: string;
        params?: string[];
        prefix?: string | IrcPrefix;
        tags?: Record<string, string>;
    },
): string
Formats an IrcMessage (or a message-shaped object) into a single line, without the trailing CRLF (the writer appends it).

The last parameter is automatically prefixed with : when it contains a space, is empty, or itself starts with : - the cases where it must be sent as a trailing parameter. tags and prefix are emitted when present (a prefix may be a raw string or an IrcPrefix).
Parameters
- msg: {
      command: string;
      params?: string[];
      prefix?: string | IrcPrefix;
      tags?: Record<string, string>;
  }
  The command, params, and optional tags/prefix to serialize.
Returns string
The formatted line (no CRLF).
