cfn-python-lint is a linter for AWS CloudFormation template file.

Website: https://github.com/awslabs/cfn-python-lint


-------------------------------------------------------------------------------
Installation

Install cfn-python-lint using either pip or brew: >

  pip install cfn-lint
<
If pip is not available use setuptools. >

  python setup.py clean --all
  python setup.py install
<
You can install the linter via brew on macOS. >

  brew install cfn-lint
<

-------------------------------------------------------------------------------
Configuration

To get cloudformation linter to work on only CloudFormation files we must set
the buffer |filetype| to `yaml.cloudformation`.  This causes ALE to lint the
file with linters configured for cloudformation and YAML files.

Just put the following in `ftdetect/cloudformation.vim`: >

  au BufRead,BufNewFile *.template.yaml set filetype=yaml.cloudformation

This will get both cloudformation and yaml linters to work on any file with
`.template.yaml` extension.
