Because discord and slack are proprietary.
I've tried a few times to get into irssi, but realized the only way I'd be able to use it is with a long term running VPS, and documenting my steps here.
Login to VPS. Start tmux with
tmux new -s irssi irssi
If you later logout, you can re attach with:
tmux attach -t irssi
or alternatively, if you only have one tmux window open:
NOTE: You can close the window (I have a kill shortcut on F12) or ctrl-b d to detach from tmux.
Add IRC server if not already saved.
/server add -auto -network Freenode irc.freenode.net 6667
Connect to server.
Can alternatively do
Add your name to freenode, if not already saved (this is a benefit of saving the server)
/network add -nick <your-nick> Freenode
When you login, you will want to register, if you haven't already. Then follow the server's instructions for the password. The server's output often displays on a different window than your default. So
to switch to the next IRSSI window.
If you want a new window:
If you want to get rid of the split window
/window hide #
You might have to turn off the "sticky" window. It will prompt you if necessary, for example if you hit CTRL-N
Servers manage search differently. You can always /list, but that is too many to read. For freenode:
/msg alis LIST * -topic electronics
There are more instructions here: https://freenode.net/kb/answer/findingchannels But the help doc is outdated, and at least one of the examples doesn't work (2019/10). So just use above.
After you search, scroll up pages in irssi default setup with:
Just the page up key. Much easier than screen which requires changing modes.
Security on IRC
Don't use your home internet connection, use a VPS. You can get VPS for extremely cheap ($10-15/yr) which are perfect for IRC.
