lotico@ubuntu:~/test$ sudo gem install linkeddata Building native extensions. This could take a while... Successfully installed nokogiri-1.6.6.2 Fetching: htmlentities-4.3.3.gem (100%) Successfully installed htmlentities-4.3.3 Fetching: rdf-xsd-1.1.3.gem (100%)
For best results, use nokogiri and equivalent-xml gems as well. These are not hard requirements to preserve pure-ruby dependencies.
Successfully installed rdf-xsd-1.1.3 Fetching: rdf-microdata-2.0.1.gem (100%) Successfully installed rdf-microdata-2.0.1 Fetching: rdf-n3-1.1.3.gem (100%) Successfully installed rdf-n3-1.1.3 Fetching: tilt-2.0.1.gem (100%) Successfully installed tilt-2.0.1 Fetching: haml-4.1.0.beta.1.gem (100%)
HEADS UP! Haml 4.0 has many improvements, but also has changes that may break your application:
- Support for Ruby 1.8.6 dropped
- Support for Rails 2 dropped
- Sass filter now always outputs <style> tags
- Data attributes are now hyphenated, not underscored
- html2haml utility moved to the html2haml gem
- Textile and Maruku filters moved to the haml-contrib gem
