Get me the weather (with Elixir)! You'll want to find some cities on https://www.findmecity.com/ to get a WOEID or "Where on Earth IDentifier". That's the input for the CLI itself.
This is a basic Mix project. This is a CLI, so I'm building as an escript.
Fetch the dependencies:
mix deps.get
Build with whatever environment (dev, prod, test)
MIX_ENV=prod mix escript.build
And run the script, or move it into your path:
./_build/ex_weather
*note: I'll go ahead and just vendor the compiled binary in the root directory, but feel free to build it again
Here are some basic commands you can run to get started:
Fetch the max average temperature of 7 days for SLC, LA, NYC, and Boise. Also set the concurrency to 2 and enable verbose logging. This will let slow the process a little and let you inspect the behavior:
╰─❯ ex_weather --verbose --concurrency 2 --days 7 2487610 2442047 2459115 2366355
Print out a help prompt of options:
╰─❯ ex_weather --help
ex_weather is a toy project to test out some Elixir.
USAGE:
ex_weather [OPTIONS] INPUT
OPTIONS:
-h, --help
-v, --verbose Set the log output to debug level
-c, --concurrency Set the maximum concurrency for the http calls
(default: 5)
-d, --days Number of days to average the max_temp
(default: 6, max: 10) -- after so many days, there isnt much data
INPUT:
<locations>... The location(s) ID or "woeid" (Where on earth identifier)
see: https://www.findmecity.com/
Example:
Get the average max_temp for SLC, LA, and NYC
$ ex_weather 2487610 2442047 2459115
Get the average max_temp for LA over 3 days
$ ex_weather --days 3 2442047
