coc-cfn-lint

Coc (coc.nvim) extension for cfn-python-lint.

Requirements

• coc.nvim
• cfn-python-lint

Install

Inside Vim/Neovim, run:

:CocInstall coc-cfn-lint

Features

• Lints JSON/YAML CloudFormation or SAM templates upon open/save
  • Will attempt to run cfn-lint from your project root directory, in order to detect any project-specific configuration (.cfnlintrc, .cfnlintrc.yaml, or .cfnlintrc.yml)

Configuration

This extension can be configured via these top-level configuration items. Live reload of settings is also supported, which means you can change these settings without needing to reload the file/editor.

Setting	Default	Description
cfnlint.path	"cfn-lint"	Path to cfn-lint
cfnlint.lintOnOpen	true	Enable linting upon opening a valid CloudFormation JSON/YAML file
cfnlint.lintOnSave	true	Enable linting upon saving a valid CloudFormation JSON/YAML file
cfnlint.detectCfnRegExps	[]	Array of RegExp strings. If any of these match in a JSON/YAML file, that file will be linted. This can be useful to detect non-standard CloudFormation/SAM templates, as the built-in checks look for a standard CloudFormation/SAM template
cfnlint.ignoreRulesRegExps	[]	Array of RegExp strings. If any of these match a cfn-lint result message, that result is ignored. This can be useful alongside cfnlint.ignoreRules
cfnlint.awsRegions	[]	Array of AWS regions to test against. Defaults to all regions. This is useful because certain rules (such as "E3001") check whether resources are supported in the given regions
cfnlint.ignoreBadTemplate	false	Ignore bad template errors
cfnlint.ignoreRules	[]	Array of rule ID prefixes to ignore (e.g. ["E3", "E1029"])
cfnlint.includeRules	[]	Array of rule ID prefixes to include. Some checks, such as Informational checks (beginning with "I") are disabled by default, and can be enabled by setting this to ["I"]
cfnlint.customRules	[]	Array of paths containing additional rules. These can be either directories containing Python file(s), or an import path to a Python module
cfnlint.includeExperimentalRules	false	Whether to include experimental rules
cfnlint.ruleConfigurations	[]	Array of rule configurations (e.g. ["E3012:strict=false"]
cfnlint.overrideSpecPath	null	Path to a CloudFormation resource specification override file
