The command line irc client I’m using these days is weechat. It’s not exactly the irc client I’d make myself1, but it gets the job done.
$ sudo apt install weechat
Launch it at the command line with weechat
.
It’ll open its text user interface full screen.
From there you are presented with the “weechat” buffer.
Your cursor will be at the command line at the bottom of the screen.
You can enter slash commands from there, such as /help
.
Scroll the output buffer using PgUp and PgDn.
Irc allows you to connect to multiple servers. You can even host your own.
Add a server like so:
[...] /server add libera irc.libera.chat/6697 -ssl -autoconnect
Handily, this example can be found verbatim in /help server
.
The server will autoconnect the next time you launch weechat. To connect in the current session, enter:
[...] /connect libera
The server will open in a new buffer for libera. You can see your buffers on the left an area called the buflist
.
You can move between buffers with meta+up and meta+down.
The irc auth model is a bit funky - you authenticate to a server by messaging a special user called NickServ.
By default, your irc username will be the same as your computer username. If you don’t want to use that, persistently customize your “nick” like so:
[...] /set irc.server.libera.nicks <yourusername>
or one-off:
[...] /nick <yourusername>
Register your nickname with the special user NickServ
:
[...] /msg NickServ register <libera_password> <email>
The password will show as *********
. I guess it can’t have spaces.
The NickServ will respond with instructions.
When you log on, you’ll see a set of messages like:
| NickServ (NickServ@services.libera.chat): This nickname
| is registered. Please choose a different nickname, or
| identify via /msg NickServ IDENTIFY yourusername <password>
| NickServ (NickServ@services.libera.chat): You have 30
| seconds to identify to your nickname before it is
| changed.
Like it says, you can authenticate by messaging the special NickServ user, as follows:
/msg NickServ identify <your password>
You might want to paste in a password using control+shift+v.
Your password will display as ********
.
It’s a hassle to do message your password every time you connect to irc, so it’s nice to set your password persistently.
First you’ll need to set a weechat password as follows:
[...] /secure passphrase <weechat_password>
This password will encrypt your weechat data. Now you can securely set and use passwords like so:
[...] /secure set libera_password <libera_password>
[...] /set irc.server.libera.sasl_password "${sec.data.libera_password}"
When you open weechat, it’ll prompt you for your weechat passphrase,
unless you set the environment variable WEECHAT_PASSPHRASE
.
I store mine in pass
and set it in my ~/.profile
:
export WEECHAT_PASSWORD=$(pass weechat)
Source your .profile
and weechat
will automatically decrypt your weechat data and log you in from here on out!
My kind of irc client would be more command-line oriented: I’d expect to be able to join straight into a channel by something like irc libera #emacs
, and also handle those trendy links like ircs://irc.libera.chat/lobsters
. I’d also build a bouncer daemon into the irc client itself. If this irc client exists already let me know! ↩
