Code Inspections in YAML

This topic lists all PhpStorm code inspections available in YAML.

You can toggle specific inspections or change their severity level on the Editor | Inspections page of settings Ctrl+Alt+S.

Inspection	Description	Default Severity
Deprecated YAML key	Reports deprecated keys in YAML files. Deprecation is checked only if there exists a JSON schema associated with the corresponding YAML file. Note that the deprecation mechanism is not defined in the JSON Schema specification yet, and this inspection uses a non-standard `deprecationMessage` extension. Scheme deprecation example: { "properties": { "SomeDeprecatedProperty": { "deprecationMessage": "Baz", "description": "Foo bar" } } } The following is an example with the corresponding warning: SomeDeprecatedProperty: some value	Weak warning
Duplicated YAML keys	Reports duplicated keys in YAML files. Example: same_key: some value same_key: another value	Error
Recursive alias	Reports recursion in YAML aliases. Alias can't be recursive and be used inside the data referenced by a corresponding anchor. Example: some_key: &some_anchor sub_key1: value1 sub_key2: *some_anchor	Error
Unresolved alias	Reports unresolved aliases in YAML files. Example: some_key: *unknown_alias	Error
Unused anchor	Reports unused anchors. Example: some_key: &some_anchor key1: value1	Warning
Validation by JSON Schema	Reports inconsistencies between a YAML file and a JSON Schema if the schema is specified. Scheme example: { "properties": { "SomeNumberProperty": { "type": "number" } } } The following is an example with the corresponding warning: SomeNumberProperty: hello world	Warning
