Greenday: How to install and use tmux

2016-10-14T21:38:03Z

How to install and use tmux

New page

Once upon a time there was BitchX. Then there was Irssi. Now there is Weechat. More and more people are switching over to Weechat from Irssi, probably coz the colours make IRC easier to read and follow. Problem is, for the Irssi user, Weechat may be a tad confusing.

Weechat documentation can be tricky to follow, so this page is an attempt to make simple those bizarre and abstract commands.

== Running Weechat ==

Dregin is a big Weechat fanboi. And as such, he has his own special builds designed for Redbrick. Azazel is the current login machine, dregin has compiled a version of Weechat that runs on azazel:

/home/associat/d/dregin/root_azazel/bin/weechat-curses

Copy and paste that into your terminal command line, hit enter, and give yourself a pat on the back.

== Compiling Weechat ==
You can run
~edu/compileweechat
This is only recommended for running it the first time as it will overwrite your weechat config.
If You want to update your install just run
~edu/updateweechat
or
git clone https://github.com/weechat/weechat
cd weechat
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=$HOME -DENABLE_NLS=OFF
make
make install
echo '*/upgrade ~/bin/weechat' > `find ~/.weechat -name "weechat_fifo_*"`
rm -rf ~/weechat

==Customising Weechat ==
Weechat can be very basic when you first run it so here are some conf files to set it up with.
cp ~edu/wcconf/* ~/.weechat/
you need to set your nick for the server
vim ~/.weechat/irc.conf
change “nicks” field to your username

If you ran the ~edu/compileweechat this will already have been done for you

== Basic use ==

=== Connecting to a server and channel ===

When you hit 'chat' on Redbrick, you start Irssi, you're automatically connected to a server, then you're joined to Redbrick's #lobby. This all happens behind the scenes, and with Weechat, you need to do this manually. Fear not: it's easy.

When you start Weechat, you won't get connected to a server or channel. To connect to Redbrick's IRC sever, type:

/connect irc.redbrick.dcu.ie

Then to join #lobby:

/join #lobby

As well as showing you how IRC clients (such as Weechat or Irssi or whatever) connect to stuff, this should also show you how to connect to other servers and channels outside of Redbrick.

To connect to any server, simply enter /connect <server_address>. You will probably be greeted with various messages and such from that server. To join a channel on that server, just type /join <channel_name>.

=== Navigation ===

Like Irssi, you can move between windows/buffers using Alt+<num>. You can also type /buffer <num> (similar to /win <num> in Irssi).
Unlike irssi you can do Alt+j then <num> to change to a number greater the 10 .

F5 and F6 move to the preceding and succeeding buffer, respectively.

You can move buffers (chat windows) with /buffer move. In a channel, type:

/buffer move <num>

(where <num> is any number you want). That channel is now accessible at Alt+<num>

=== Changing between servers ===

Weechat will generally assume that whatever channel you're in, that's also the server you're operating on. So you can chat away as you wish and issue general commands.

However, for some commands, you will need to let Weechat know what server you're on.

Hit Alt+1. This will bring you to your status window. Along the bottom you will see the time, number of channels, the server you're connect to, as well as other channel stuff.

Press Ctrl+x. If you're connected to multiple servers, the ''server'' section will change, telling you which server Weechat is connect to. So now you can issue commands to that server (such as /nick) without affecting other servers.

For example, I am currently connected to irc.redbrick.dcu.ie and to irc.starchat.net. If I hit Ctrl-x I can switch to StarChat, and change my nickname there without it affecting Redbrick's IRC.

== Mobile ==

weechat has a mobile app you can get from the [https://play.google.com/store/apps/details?id=com.ubergeek42.WeechatAndroid google play store] or from the [https://github.com/ubergeek42/weechat-android github].
Before we set up the app we need to go too weechat on the terminal and type in:
/relay add weechat 1337
then we need to set the password
/set relay.network.password "your-secret-password"

now on the Phone launch the app and in settings
In connection settings
Relay host: localhost
Relay Port: 1337 (choose your own port)
Relay password: your-secret-password
Connect type: SSH tunnel
then in SSH Tunnel settings
SSH host: redbrick.dcu.ie
SSH username: your username
SSH port: 22
if you have an ssh key add the route to the key on your phone in SSH Private key file and put the passphrase in the SSH password/key passphrase box, if you dont just put your password in there

== Special commands ==

=== Keybinds ===

Keybinds are handy, especially if you have over 10 channels open. I use Alt+<num> to get to channels, but clearly this only works from 1 up to 0 (on a keyboard). So for channels in higher numbers, you can ''bind'' keys: i.e. Alt+q gets me to channel 11; Alt+y gets me to channel 16.

/key bind meta-q /buffer 11

"Key" and "bind" are self-explanatory. "Meta" is Weechat's word for Alt (so meta-q is the same as Alt+q). /buffer 11 is the command that's executed once meta-q (Alt-q) is typed.

You can build up these to meta-w, meta-e, meta-r for buffer 2, buffer 3, buffer 4, etc etc.

Of course, you can bind any key combo to any weechat command; it's not necessary to make them Alt+<num> commands.

'''Note:''' Watch out for caps lock if you're keybinding. If you bind Alt+y to a command, Alt+Y won't work (unless you bind that separately). If you find your binds aren't working, check your caps.

== Triggers ==

Triggers are the swiss army knife of weechat. They can replace a '''lot''' of scripts, and we're still finding things to turn into trigger

=== Turn any line with "nsfw" in it bright red ===
/trigger addreplace nsfw modifier weechat_print "${tg_notify} && ${tg_message_nocolor} =~ .*nsfw.*" "/(.*)/${tg_prefix}\t${color:red}!NSFW! ${tg_message}"
=== Make urls underlined and blue ===
/trigger addreplace url_color modifier "weechat_print" "${tg_tags} !~ irc_quit" ";[a-z]+://\S+;${color:32}${color:underline}${re:0}${color:-underline}${color:reset};" ""
===Strip items such as time from screen on smaller screens ===
/trigger addreplace resize_small_timestamp signal signal_sigwinch "${info:term_width} < 200" "" "/set weechat.look.buffer_time_format \"\""
===add items such as time from screen on bigger screens ===
/trigger addreplace resize_big_timestamp signal signal_sigwinch "${info:term_width} >=200" "" "/set weechat.look.buffer_time_format %H:%M:%S "

=== turn off nicklist on smaller screens ===
/trigger addreplace resize_big signal signal_sigwinch "${info:term_width} >= 100" "" "/bar show nicklist"
/trigger addreplace resize_small signal signal_sigwinch "${info:term_width} < 100" "" "/bar hide nicklist"
=== turn off buffer list on small screens ===
/trigger addreplace resize_small_buffer signal signal_sigwinch "${info:term_width} < 100" "" "/bar hide buffers"
/trigger addreplace resize_big_buffer signal signal_sigwinch "${info:term_width} >= 100" "" "/bar show buffers"

==Conditions==

Conditions can be used to customize weechat depending on certain variables

===Turn off nicklist on small windows===
/set weechat.bar.nicklist.conditions "${nicklist} && (${window.win_width} > 100 || ${buffer.full_name} == irc.bitlbee.&bitlbee)"

===Hide buffer list on small terminals===
/set weechat.bar.buffers.conditions "${info:term_width} > 100"

===Turn off status on nonactive windows ===
/set weechat.bar.status.conditions "${active}"

== Spell Checker ==

Weechat uses a handy aspell plugin to check your spelling. To enable it, either use iset or use
/set aspell.check.enabled on

Aspell has a few settings which you may find useful

/set aspell.check.real_time on
/set aspell.check.word_min_length 2
/set aspell.check.default_dict "en"
/set aspell.check.suggestions 3

Or alternatively if you use iset, search for aspell

The aspell plugin can also offer suggestions as of 0.4.0 and it can be added as an item to your status bar. The item should be added to weechat.bar.status.items. For instance:
/set weechat.bar.status.items "time |,buffer_number+:buffer_name+(buffer_modes)+ |,buffer_nicklist_count |,hotlist |,[aspell_suggest]
