Question

I want to write a Ruby program that will fetch all the unique http links in the last 100 most recent tweets using the supplied hashtag.

Where should I start from?

Answer 1

If working with gem is okay with you, then, you should have a look at Twitter ruby gem.

tweets_result=Twitter.search("#tag_to_search -rt", :rpp => 100)

It will give you 100 results (excluding retweets, thus maintaining some uniquness).

To display the results:

tweets_result.each{|x| puts x.text}
