# igliker.rb - An Instagram mass list liker by pet'rc
# ---------------------------------------------------
#
# Takes a list of accounts and likes the latest post
# on each by remote controlling a Firefox instance.
#
# This is quite technical to use and requires you have Ruby
# installed (such as on macOS), as well as Firefox, and
# be happy using the terminal.
#
# To install:
#   - Load a terminal emulator
#   - Run 'ruby -v'
#     .. if you get a response like:
#        "ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-darwin15]"
#     .. you're good to go!
#   - Install Firefox
#   - Install Geckodriver
#     .. get the latest one for your OS at
#        https://github.com/mozilla/geckodriver/releases
#     .. unarchive and put 'geckodriver' file into
#        /usr/local/bin/ or /usr/bin/
#   - Put THIS file into a directory and call it 'igliker.rb'
#   - gem install selenium-webdriver dotenv
#     .. if you get a permissions error, then try:
#          sudo gem install selenium-webdriver dotenv
#     .. and put your password in to install as admin.
#
# To run, put a list of IG usernames into names.txt, then:
#     IG_USERNAME=yourusername IG_PASSWORD=yourpassword ruby igliker.rb names.txt
#
#   OR..
#     In .env file put your Instagram credentials:
#       IG_USERNAME=yourusername
#       IG_PASSWORD=yourpassword
#
#     Then run:
#       ruby igliker.rb names.txt
