+# tmux+irssi as a systemd user-service
+
+A collection of hacks to run [irssi](https://irssi.org/) inside [tmux](https://tmux.github.io/) via a systemd user service.
+
+I hope by publishing this that someone can be inspired to find a way to do it without so many awful hacks (and let me know about it!).
+
+## Why
+
+I use [adv_windowlist.pl](https://github.com/irssi/scripts.irssi.org/blob/master/scripts/adv_windowlist.pl) which has great integration with tmux.
+
+I want irssi to start and stop cleanly on system reboot, which means starting up tmux.
+
+## What
+
+* `irssi.service`: systemd user service. Install to `/etc/systemd/user/`
+* `tmux-irssi.env`: optional environment file. Install to `~/.config/`
+* `pid.pl`: irssi script to write a pid file. Install to `~/.irssi/scripts/` (and symlink in `~/.irssi/scripts/autorun/`)
+
+## Installation
+
+After installing the files, just enable the service:
+
+```sh
+$ systemctl --user daemon-reload
+$ systemctl --user enable --now irssi
+```
+
+The you can connect to tmux with
+
+```sh
+tmux -L irssi attach
+```
