Just as a heads up, I haven't really tested this since a lot of it is stuff I don't use or know how to set up without some reading up. I have tested the nu_conda_2 change since I have a python project that I use that for, and I could look into testing more of it if needed. I've tried finding (naively using `/sys\W/`) all the usage of the old plain `sys` calls and replacing them with alternates as appropriate, which mostly has been to swap a `(sys).host.name` call into a `$nu.os-info.name` one, since it'll be tad faster and more consistent across platforms with naming (especially as the value comes from the [rust stdlib](https://doc.rust-lang.org/std/env/consts/constant.OS.html) and is very predictable). Fixes #897

# 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. It will need to be tweaked to actually be used in a
|
|
# prompt, but for now it just prints the weather in these 3 ways.
|
|
# 1. if it's never been run, it runs the weather command and saves the json cache info
|
|
# 2. if the interval has not expired yet, it prints the Cached information
|
|
# 3. if the interval has expired, it runs the weather command again and caches the info
|
|
|
|
# this script is dependent on get-weather
