Before, it was required to specify all the options when customizing a
rule. For instance, one could use `empty-lines: enable` or `empty-lines:
{max: 1, max-start: 2, max-end: 2}`, but not just `empty-lines: {max:
1}` (it would fail with *invalid config: missing option "max-start" for
rule "empty-lines"*).
This was a minor problem for users, but it prevented the addition of new
options to existing rules, see [1] for an example. If a new option was
added, updating yamllint for all users that customize the rule would
produce a crash (*invalid config: missing option ...*).
To avoid that, let's embed default values inside the rules themselves,
instead of keeping them in `conf/default.yaml`.
This refactor should not have any impact on existing projects. I've
manually checked that it did not change the output of tests, on
different projects:
- ansible/ansible: `test/runner/ansible-test sanity --python 3.7 --test yamllint`
- ansible/molecule: `yamllint -s test/ molecule/`
- Neo23x0/sigma: `make test-yaml`
- markstory/lint-review: `yamllint .`

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.

Installation
^^^^^^^^^^^^
On Fedora / CentOS (note: `EPEL <https://fedoraproject.org/wiki/EPEL>`_ is
required on CentOS):
.. code:: bash
sudo dnf install yamllint
On Debian 8+ / Ubuntu 16.04+:
.. code:: bash
sudo apt-get install yamllint
On Mac OS 10.11+:
.. code:: bash
brew install yamllint
Alternatively using pip, the Python package manager:
.. code:: bash
pip install --user yamllint
Usage
^^^^^
.. code:: bash
# Lint one or more files
yamllint my_file.yml my_other_file.yaml ...
.. code:: bash
# Lint all YAML files in a directory
yamllint .
.. code:: bash
# Use a pre-defined lint configuration
yamllint -d relaxed file.yaml
# Use a custom lint configuration
yamllint -c /path/to/myconfig file-to-lint.yaml
.. code:: bash
# Output a parsable format (for syntax checking in editors like Vim, emacs...)
yamllint -f parsable file.yaml

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
Specific files can be ignored (totally or for some rules only) using a
``.gitignore``-style pattern:
.. code:: yaml
# For all rules
ignore: |
*.dont-lint-me.yaml
/bin/
!/bin/*.lint-me-anyway.yaml
rules:
key-duplicates:
ignore: |
generated
*.template.yaml
trailing-spaces:
ignore: |
*.ignore-trailing-spaces.yaml
/ascii-art/*
