a ruby library to fetch and parse meta tags which represent OpenGraph Protocol and TwitterCard.

Installation

Add this line to your application's Gemfile:

gem 'ogpr'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ogpr

Usage

require "ogpr"

# Fetch and parse meta tags from the url
ogp = Ogpr.fetch("http://example.com/path/to/page")
# Parse the string as meta tags.
ogp = Ogpr.parse("<meta ....>")

# Fetch OpenGraph meta tag
og = ogp.open_graph
if og
  og.each_pair do |k, v|
    puts "#{k} => #{v}"
  end
end

# Fetch TwitterCard meta tag
card = ogp.twitter_card
if card
  card.each_pair do |k,v|
    puts "#{k} => #{v}"
  end
end

# Fetch all of OpenGraph and TwitterCard meta tag
if ogp.exist?
  ogp.title       # og:title or twitter:title
  ogp.type        # og:type or twitter:card
  ogp.description # og:description or twitter:description
  ogp.image       # og:image or twitter:image
  ogp.url         # og:url or twitter:url
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
