slotThe 2c529c3cb8 Link to Libera, Matrix instead of Freenode
The project has moved away from Freenode as an IRC network[1], and there
is now a quite large channel on Libera.  As such, we should point users
towards that instead.

This also changes all examples to refer to libera instead of freenode
as, with the recent deletion of all freenode channels, it is perhaps
where most communities are to be found nowadays.

Finally, also link to the official Matrix room[2] as an alternative to
IRC.

Weechat

Weechat can be configured to include your choice of plugins, reducing its closure size from the default configuration which includes all available plugins. To make use of this functionality, install an expression that overrides its configuration such as

weechat.override {configure = {availablePlugins, ...}: {
    plugins = with availablePlugins; [ python perl ];
  }
}

If the configure function returns an attrset without the plugins attribute, availablePlugins will be used automatically.

The plugins currently available are python, perl, ruby, guile, tcl and lua.

The python and perl plugins allows the addition of extra libraries. For instance, the inotify.py script in weechat-scripts requires D-Bus or libnotify, and the fish.py script requires pycrypto. To use these scripts, use the plugin's withPackages attribute:

weechat.override { configure = {availablePlugins, ...}: {
    plugins = with availablePlugins; [
            (python.withPackages (ps: with ps; [ pycrypto python-dbus ]))
        ];
    };
}

In order to also keep all default plugins installed, it is possible to use the following method:

weechat.override { configure = { availablePlugins, ... }: {
  plugins = builtins.attrValues (availablePlugins // {
    python = availablePlugins.python.withPackages (ps: with ps; [ pycrypto python-dbus ]);
  });
}; }

WeeChat allows to set defaults on startup using the --run-command. The configure method can be used to pass commands to the program:

weechat.override {
  configure = { availablePlugins, ... }: {
    init = ''
      /set foo bar
      /server add libera irc.libera.chat
    '';
  };
}

Further values can be added to the list of commands when running weechat --run-command "your-commands".

Additionally it's possible to specify scripts to be loaded when starting weechat. These will be loaded before the commands from init:

weechat.override {
  configure = { availablePlugins, ... }: {
    scripts = with pkgs.weechatScripts; [
      weechat-xmpp weechat-matrix-bridge wee-slack
    ];
    init = ''
      /set plugins.var.python.jabber.key "val"
    '':
  };
}

In nixpkgs there's a subpackage which contains derivations for WeeChat scripts. Such derivations expect a passthru.scripts attribute which contains a list of all scripts inside the store path. Furthermore all scripts have to live in $out/share. An exemplary derivation looks like this:

{ stdenv, fetchurl }:

stdenv.mkDerivation {
  name = "exemplary-weechat-script";
  src = fetchurl {
    url = "https://scripts.tld/your-scripts.tar.gz";
    sha256 = "...";
  };
  passthru.scripts = [ "foo.py" "bar.lua" ];
  installPhase = ''
    mkdir $out/share
    cp foo.py $out/share
    cp bar.lua $out/share
  '';
}
