LinkOracle

Code Climate

TODO: Write a gem description

Installation

Add this line to your application's Gemfile:

gem 'link_oracle'

And then execute:

$ bundle

Or install it yourself as:

$ gem install link_oracle

Usage

To parse a link and extract information:

link_data = LinkOracle.extract_from('http://example.com')

This will return a LinkData object. This object makes a a semi-intelligent guess about which image, title, and description to use. To access these defaults:

title = link_data.title
image_url = link_data.image_url
description = link_data.description

The LinkData object also contains the parsed data:

parsed_data = link_data.parsed_data

Finally, the LinkData object contains the results from individual sections broken into OpenGraph, Meta, and Body. If you are only interested in OpenGraph results:

found_og_data = link_data.og
title = found_og_data.title
image_url = found_og_data.image
description = found_og_data.description

For Meta or body:

found_meta_data = link_data.meta
found_body_data = link_data.body
