yamllint
========
A linter for YAML files.
yamllint does not only check for syntax validity, but for weirdnesses like key
repetition and cosmetic problems such as lines length, trailing spaces,
indentation, etc.

Features
^^^^^^^^
Here is a yamllint configuration file example:
.. code:: yaml
extends: default
rules:
# 80 chars should be enough, but don't fail if a line is longer
line-length:
max: 80
level: warning
# don't bother me with this rule
indentation: disable
Within a YAML file, special comments can be used to disable checks for a single
line:
.. code:: yaml
This line is waaaaaaaaaay too long # yamllint disable-line
or for a whole block:
.. code:: yaml
# yamllint disable rule:colons
- Lorem : ipsum
dolor : sit amet,
consectetur : adipiscing elit
# yamllint enable
