timed_weather_run_env.nu

# This script will run a command, in this case get_weather, at a prescribed interval
# This is meant to be run from your prompt so that it runs every time you cd or
# run a command. Each time it will check if it's been longer than the interval and
# if so, run the command, otherwise it uses the cached weather information.
# I wrote this so I could have weather in my prompt but not pay the price of hitting
# the web for every prompt.

# this script is dependent on get-weather
use get-weather.nu get_weather
