Jekyll static site validation

You can add this Rake task to validate a jekyll site:

desc 'validate _site with validate website'
task validate: :build do
    Dir.chdir("_site") do
      system("validate-website-static",
               "--verbose",
               "--exclude", "examples",
               "--site", HTTP_URL)
      exit($?.exitstatus)
    end
  end
end

HTML5

Tidy5

If the libtidy5 is found on your system this will be the default to validate your html5 document. This does not depend on a tier service everything is done locally.

Validator.nu web service

When --html5-validator nu option is used HTML5 support is done by using the Validator.nu Web Service, so the content of your webpage is logged by a tier. It's not the case for other validation because validate-website use the XML Schema or DTD stored on the data/ directory.

Please read http://about.validator.nu/#tos for more info on the HTML5 validation service.

Use validator standalone web server locally

You can download validator jar and start it with:

java -cp PATH_TO/vnu.jar nu.validator.servlet.Main 8888

Then you can use validate-website option:

--html5-validator-service-url http://localhost:8888/
# or
export VALIDATOR_NU_URL="http://localhost:8888/"

This will prevent you to be blacklisted from validator webservice.

Tests

With standard environment:

bundle exec rake
