With the latest release of mirc, $msgtags support is supposed to be included.
I am trying to read in ircv3 tags, using this new identifier and wrote some simple code to check. I've requested tags using the appropriate CAP REQ.
if (subscriber=1 isin $msgtags) {
echo -a yes
}
if (subscriber=0 isin $msgtags) {
echo -a no
}
My expectation is for yes to be output, with the assumption that subscriber is indeed 1.
