# ==============================DEPENDENCIES=================================
# This script requires jq for manipulating JSON data.
# Requires: https://stedolan.github.io/jq/
# Install via brew:  `brew install jq`
# ===========================================================================

# ===============================DATA SOURCE=================================
# This script curls JSON data from the NovelCOVID API, available at:
# https://corona.lmao.ninja
# GitHub: https://github.com/novelcovid/api
# There are a few other APIs or tools for pulling COVID-19 data, several of
# which point back to this one. v1.0 of this script used a node.js-based CLI
# to pull data, leading to formatting issues across systems and some
# inconsistencies in iTerm/Terminal and in the BitBar output.
# ===========================================================================


# ==============================CONFIGURATION================================
# READ THIS SECTION:
# Set these variables to configure the output to your liking.
#
# Choose which states you want stats for. Any states you add here will
# be shown within the dropdown menu. Be sure to separate each state in
# its own parentheses with a space between each string.
# Example:
# STATES=("North Carolina" "New York" "California")
STATES=("North Carolina" "New York" "California")
#
# ALTERNATIVE TOP STATES MODE:
# Instead of choosing states, you can choose to have the top n states ranked
# by number of cases, where n is a number you set with the variable N_STATES.
# Comment/uncomment one of the next two lines to set your preference.
TOP_N=true     # Sets the script to show the top states
# TOP_N=false    # Sets the script to show user-selected states
#
# Set the number of states you want to see when TOP_N is true. The data
# source has 57 entries, including Puerto Rice, US Virgin Islands, and the
# Diamond Princess cruise. In case the maintainers add more entries, set the
# number to something much higher (it won't effect performance)
N_STATES=500
# ===========================================================================
# ==============================SCRIPT BELOW=================================
