WeeChat is available in the [extra] repo. Install by running:

# pacman -S weechat

There is also weechat-gitAUR in the AUR, install with your favorite AUR Helper or makepkg.

Running WeeChat

WeeChat is going to have multiple interfaces at some point, run weechat-[interface] to start WeeChat.

As WeeChat currently only has a Ncurses interface the command to start WeeChat is:

$ weechat-curses


You can configure WeeChat in 2 ways: internally, from the command line or by editing the .conf files located in ./weechat directly. WeeChat will automatically save settings on exit, so if you are editing a .conf file in an editor, be sure to run /reload from the console before exiting, otherwise your changes will be lost.


You can get a list of all configurable options by typing /set in the weechat buffer window. Since there are nearly 600 default configurable options, you can search through them with a wildcard syntax: /set irc.server.* or /set *server* as an example. You can get help on each option with the /help command:

/help irc.server.freenode.<option name>

Configuration Files

The .conf files for weechat are saved to ~/.weechat. These files are not commented. Detailed information can be found within the program itself (see Internally above), or WeeChat's user guide.

Connecting to a server

You can connect to a IRC server by using /connect.

/connect chat.freenode.net

Or if there is already a Server setup you can use:

/connect freenode

Creating a Server profile

If you plan on connecting to a server more than once it may be beneficial to create a Server.

/server add example irc.example.net/6667

Would create the server example which would connect to irc.example.net on port 6667

See the WeeChat documentation and /help server for more information.

Configuring SSL

Many IRC servers, including freenode where #archlinux is, support SSL.

If you're making a server with /server add -ssl to the end of the line, for example:

/server add FreenodeSSL chat.freenode.net/7000 -ssl
Warning: Some servers need the ssl_dhkey_size value changed to something lower. For example, if you're using freenode you'll need to set /set irc.server.FreenodeSSL.ssl_dhkey_size 1024
Note: Different servers may, and probably will have a different port than 7000 - this is server specific.

You can do the same thing if using /connect.

/connect chat.freenode.net/7000 -ssl

Tips and Tricks


WeeChat can be upgraded without disconnecting from the IRC servers (non-SSL connections only):


This will load the new WeeChat binary and reload the current configuration.


Aliases can be created to simplify commonly executed commands. A nice example is Wraithan's smart filter alias:

Smart Filter
First, we need to enable smart filters:

/set irc.look.smart_filter "on"

Next, we will create the sfilter alias:

/alias sfilter filter add irc_smart_$server_$channel irc.$server.$channel irc_smart_filter *

We can now type


in any buffer, and the smart filter will only be enabled for that buffer.

The following alias will remove a previously enabled smart filter in the current buffer:
Add the alias:

/alias rmsfilter filter del irc_smart_$server_$channel

and execute it by


Key Bindings

Some helpful bindings:

To use ctrl-left/right arrow keys to jump to next/previous words on the input line:

/key bind meta2-1;5D /input move_previous_word
/key bind meta2-1;5C /input move_next_word

Getting Help

To access WeeChat's built-in help, simply type


and the help will be displayed in the main buffer (usually buffer 1).
