JSON Superset

CUE is a superset of JSON. It adds the following conveniences:

• C-style comments,
• quotes may be omitted from field names without special characters,
• commas at the end of fields are optional,
• comma after last element in list is allowed,
• outer curly braces are optional.

JSON objects are called structs in CUE. An object member is called a field.

one: 1
two: 2

// A field using quotes.
"two-and-a-half": 2.5

list: [
	1,
	2,
	3,
]

{
    "one": 1,
    "two": 2,
    "two-and-a-half": 2.5,
    "list": [
        1,
        2,
        3
    ]
}
