Extract text from PDF(I have link to PDF) in ruby

Question

I have a link like

      http://www.downloads.com/help.pdf

I want to download this, and parse it to get the text content.

How do I go about this? I also plan to tag-ize(if there is a word like that) the extracted text

Answer 1

You can either use the pdf-reader gem (the example/text.rb example is simple and worked for me): https://github.com/yob/pdf-reader

Or the command-line utility pdftotext.

Answer 2

The Yomu gem will also be able to extract the text from a PDF (as well as other MIME types) for you.

require 'yomu'
Yomu.new(file_path).text
