Only show battery percentage on systems that have a battery

[szczys]

I share the same .tmux.conf across all systems. I finally added battery percentage display today, and I noticed that it is shown on a desktop system that doesn't have a battery (renders to 0%). I worked out this bit of code that will only display on systems that have a battery present. I'm on Linux Mint, your mileage may vary based on the distro you use and where it maps battery information:

# If system has a battery, show remaining percentage
if-shell '[ -d "/sys/class/power_supply/BAT0" ]' \
  'BATTERY="battery"' \
  'BATTERY=""'

set -g @catppuccin_status_modules_right "session host $BATTERY date_time"
