Description

IDE like PHPStorm have a great support for Yaml validation against a JSON schema.

Code completion
For example, you can use code completion for YAML documents that have the JSON schema, or you can complete anchor aliases.

The idea is to generate a schema.json from all the allowed configuration.

Example

I created a JSON schema manually for Yaml files and this was a pleasant experience to have autocompletion and errors directly highlighted in PHPStorm.
