An IRSSI theme with powerline goodness.
Clone the repository
git clone https://github.com/darac/irssi-powerline
Copy the theme to your .irssi config directory
cp irssi-powerline/solarized-powerline.theme ~/.irssi/
Copy adv_windowlist.pl into your scripts/autorun directory
cp irssi-powerline/scripts/autorun/*.pl ~/.irssi/scripts/autorun
If this is your first time using irssi, just copy the config file to your .irssi directory, otherwise, you will need to merge the changes (Basically, copy the statusbar = { ... }
section across then, in settings ensure the fe-common/core and perl/core/scripts sections are copied over).
