This is an [[IRC]] client in [[Emacs]]. I’m using [[ZNC]] as an IRC bouncer, so some of this might only apply if you’re using ZNC too.
(setq erc-hide-list '("JOIN" "PART" "QUIT"))
In spacemacs, they are set at the point of including the erc layer in your layers config.
(erc :variables
erc-server-list
'(("irc.example.com"
:port "6770"
:ssl t
:nick "nick"
:password "password")))
IMPORTANT NOTE: don’t actually put your password in the config - https://www.spacemacs.org/layers/+chat/erc/README.html#security-note
machine <irc.server.url> login <yournick> password <yourpassword> port <portnumber>
