Nanoc::Checking::Checks::Vnu

A nanoc check that validates HTML, CSS, and SVG output files locally with the Nu Html Checker (v.Nu).

Installation

Install v.Nu and place the vnu executable on your PATH.

Add this line to your application's Gemfile:

gem 'nanoc-checking-checks-vnu'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install nanoc-checking-checks-vnu

Usage

Add this line to a Ruby file inside your site's lib directory:

require 'nanoc/checking/checks/vnu'

Then execute:

$ nanoc check vnu  # prefix with `bundle exec` as appropriate

You can automatically run this check at deploy time by adding vnu to the checking section of nanoc.yaml.

By default, CSS and SVG files are validated in addition to HTML files. This can be changed by configuring the check in nanoc.yaml:

checks:
  vnu:
    also_check_css: no
    also_check_svg: no

You can further disable particular errors by passing a value for the --filterpattern option, which takes a regex matching the whole message:

checks:
  vnu:
    filterpattern: '.*color-mix.*'
