# Battery indicator for tmux/FreeBSD

This is is a little C program to indicate the current battery state and
percentage in the tmux status bar.
It uses the FreeBSD `sysctl` and is not compatible with Linux.

Requires a font that includes utf-8 symbols. Iosevka and JetBrains Mono from
NerdFonts have been tested.

Compile with

```sh
cc -O2 battery.c -o battery
```

and copy or link the executable into `~/.local/bin`, which should be on your
`$PATH`.

Edit `~/.tmux.conf` and setup the status bar with something like

```tmux
set-option -g status-right "#($HOME/.local/bin/battery)   %a, %d %b  %H:%M "
```

Reload tmux and enjoy!
