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, run
`python setup.py clean --all` then `python setup.py install`.

 Homebrew (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:

>

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

<

on `ftdetect/cloudformation.vim`

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