w3c_validator.rb

This script validates the generated guides against the W3C Validator.

Guides are taken from the output directory, from where all .html files are submitted to the validator.

This script is prepared to be launched from the railties directory as a rake task:

rake validate_guides

If nothing is specified, all files will be validated, but you can check just some of them using this environment variable:

ONLY
  Use ONLY if you want to validate only one or a set of guides. Prefixes are
  enough:

    # validates only association_basics.html
    ONLY=assoc rake validate_guides

  Separate many using commas:

    # validates only association_basics.html and migrations.html
    ONLY=assoc,migrations rake validate_guides
