Lesser Evil is a command line gem that allows the user to view tweets around the recent U.S. presidential election. Lesser Evil presents the user with a choice of candidates (Trump and Clinton) and of sentiments (angry or very angry). It then finds recent tweets about the chosen candidate, filters them through a sentiment analysis engine, and returns the angry or very angry tweets to the screen.
Lesser Evil uses the Twitter Search API and Vivek Narayanan's sentiment analysis tool. Mr Narayanan's tool is not perfect. It returns a value of positive, negative, or neutral for each input text, and also a confidence number between 0 and 100. Sometimes, though, you ask for very angry tweets and what you get is not angry at all.
Installation is simple. Install the gem on your hard drive
gem install lesser-evil
and then run it with the following command:
