Snippet no. 1: the Tweet Controller (Ruby)

Introduction

Lesser Evil (lesser-evil-cli) is a hosted Ruby gem for the command line which applies a third-party, open-source sentiment analysis tool to collect negative-affect tweets regarding the 2016 U.S. Presidential candidates. The user chooses the candidate ("Trump" or "Clinton") and the negativity threshold ("angry" or "very angry").

What does it do?

The fetch_tweets method in the Tweet Controller is the primary engine of the application. It performs the following tasks:

• Retrieves a batch of tweets. It calls (line 29) the get_batch method which makes GET requests to the Twitter Search API. The request includes search terms, desired number of results, and the maximum ID (i.e., the most recent ID from which to start the search)
• Filters them according to sentiment. The if statement of line 36 tests for sentiment negativity and user-specified intensity
• Creates a TweetSlim object from each matched tweet (line 37)
• Prints each TweetSli
