crawlem's Introduction

CrawlEm

Making a web crawler in Ruby.

Setting Up

First you need to clone this project somewhere onto your computer. Using your terminal, navigate to the location you want to store the project then paste in the following:

git clone https://github.com/salexzee/CrawlEm.git

Next, you'll need the Mechanize gem so that the project can interact with websites.

gem install mechanize

Finally, you'll need a file called urls.txt to store the crawled URLs.

touch urls.txt

Now just add 1 or more URLs to urls.txt and you'll be able to run the program.

Running the program

It's simple, just run it like any other Ruby program.

ruby crawlem.rb

If everything is working correctly, you will see something similar to:
