Adrien Vergé f656cf42d2 fix(line-length): Wrap token scanning securely 
With `allow-non-breakable-inline-mappings` enabled, every long line is
passed through `loader.peek_token()`. Even lines that are not valid
YAML. For this reason, this code must be wrapped in a `try`/`except`
block.

Closes: #21

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
