html5validator 0.2.5

Validate HTML5 files.

HTML5 Validator
===============

This was written with static site generators like `Jekyll <http://jekyllrb.com/>`_
and `Pelican <http://blog.getpelican.com/>`_ in mind that push to a static
server. ``html5validator`` is a command line executable that integrates
well with CircleCI and TravisCI and tests all static html files for
HTML5 validity.

Install
-------

This module requires Python 2.7, 3.4 or 3.5 and Java 8.
Install with ``pip install html5validator`` and run with

.. code-block:: bash

html5validator --root _build/ --ignore-re 'Attribute "ng-[a-z-]+" not allowed'

to validate all html files in the ``_build`` directory and to ignore all messages
that match the regular expression ``Attribute "ng-[a-z-]+" not allowed``.
Run ``html5validator --help`` to see the list of command line options.

This module uses the `validator.nu backend <https://github.com/validator/validator.github.io>`_
which is written in Java. Therefore, a Java Runtime Environment must be
available on your system. Since version 0.2, Java 8 is required.


Integration with CircleCI
-------------------------

Create a ``circle.yml`` file:

.. code-block:: yaml

machine:
java:
version: oraclejdk8
dependencies:
pre:
- sudo pip install html5validator
test:
override:
- html5validator --root _build/

in your repository with static html files and get HTML5 validation on every
``git push``.


Integration with TravisCI
-------------------------

Create a ``.travis.yml`` file. This is an example for a Python project:

.. code-block:: yaml

language: python
python:
- "2.7"

branches:
only:
- gh-pages

# install Java 8 as required by vnu.jar
before_install:
- sudo apt-get update
- sudo apt-get install oracle-java8-installer
- sudo update-java-alternatives -s java-8-oracle

install:
- pip install html5validator

script: html5validator --root _build/

This is an example for Java project:

.. code-block:: yaml

language: java
jdk:
- oraclejdk8 # vnu.jar requires Java 8

branches:
only:
- gh-pages

install:
- pip install --user html5validator

script: html5validator --root _build/


Fix the ``html5validator`` version by using
``pip install --user html5validator==<version number>``.

You can also use this for user pages (repositories of the form ``<username>.github.io``)
where the html files are in the master branch. You only have to remove:

.. code-block:: yaml

branches:
only:
- gh-pages

from ``.travis.yml``. I am using this on
`my own user page <https://github.com/svenkreiss/svenkreiss.github.io/blob/master/.travis.yml>`_.


Integration with CodeShip
-------------------------

Add this lines to the ``Setup Commands``:

.. code-block:: yaml

jdk_switcher use oraclejdk8
pip install html5validator


This is an example for Ruby project:

.. code-block:: yaml

rvm use 2.2.0 --install
bundle install
bundle update
export RAILS_ENV=test
jdk_switcher use oraclejdk8
pip install html5validator


Technical Notes
---------------

* If you are using grunt already, maybe consider using the
`grunt-html <https://github.com/jzaefferer/grunt-html>`_ plugin for grunt instead.
* Use ``--ignore-re 'Attribute "ng-[a-z-]+" not allowed'`` with angular.js apps.
* Example with multiple ignores: ``html5validator --root tests/multiple_ignores/ --ignore-re 'Attribute "ng-[a-z-]+" not allowed' 'Start tag seen without seeing a doctype first'``
