A Ruby script for parsing all devices from LineageOS wiki and filtering them based on some needed specifications

which_phone_should_i_buy.rb

#!/bin/env ruby

# This script assumes you have cloned the wiki:
# git clone https://github.com/LineageOS/lineage_wiki --depth 1 && cd lineage_wiki/_data/devices
#
# Then run this script with something like:
# for i in *.yml;do ruby ./which_phone_should_i_buy.rb $i "https://wiki.lineageos.org/devices/"; done
# You can use the second argument to prepend some text to the output

  # to convert it to string for consistent handling among formats
