comma

Control whether commas should be inserted inside a list of items.

Possible option values:

• "always": Insert commas inside a list of items. For single line list, there won't be trailing comma; for multiple lines list, there will be trailing comma.
• "never": Do not insert commas inside a list of items. All existed commas will be removed.
• "noTrailing": Insert commas inside a list of items without trailing comma.
• "onlySingleLine": Insert commas inside a list of items only for single line list. For multiple lines list, there won't be commas.
• "inherit": Inherit from the base comma option.

Default option value is "onlySingleLine".

This global option can be overridden by different syntax nodes. Some syntax-node-specific options will override by default instead of "inherit":

• arguments.comma
• argumentsDefinition.comma
• directives.comma (default: "never")
• enumValuesDefinition.comma (default: "never")
• fieldsDefinition.comma (default: "never")
• inputFieldsDefinition.comma (default: "never")
• listValue.comma
• objectValue.comma
• schemaDefinition.comma (default: "never")
• schemaExtension.comma (default: "never")
• selectionSet.comma (default: "never")
• variableDefinitions.comma
