No HTML5 validator

[Pierre Rudloff]

When trying to validate HTML5, the validator says "External Checker not available", but there is no package for the HTML5 validator.

Status changed to 'Confirmed' because the bug affects multiple users.

Currently, w3c-markup-validator is running the W3C's validator v1.2. I was able to get HTML5 validation working by simply installing the HTML and CGI-BIN files from their most recent release, v1.3.

The code is available here:
http://validator.w3.org/validator.tar.gz

After download, you can upgrade your install by running the following commands:

tar -xvzf validator-1.3.tar.gz
sudo cp -R validator-1.3/htdocs/* /usr/share/w3c-markup-validator/html/
sudo cp validator-1.3/httpd/cgi-bin/* /usr/lib/cgi-bin/w3c-markup-validator/

My previous comment was a bit premature. In addition to upgrading the validator itself, you need to get an external HTML5 validator running. This entails two changes: building/installing the HTML5 validator, and referencing it.

Build instructions are here, however, I have had some difficulties getting this to work:
http://about.validator.nu/#src

Afterward, it should just be a matter of adding the following to the bottom of /etc/w3c/validator.conf:

<External>
  HTML5 = http://localhost:8888/html5/
</External>
