type Token ¶

type Token struct {
	Type    Type
	Literal string
	Line    int
	Start   int
	End     int
}

Token is a struct representing a JSON token - It holds information like its Type and Literal, as well as Start, End, and Line fields. Line is used for better error handling, while Start and End are used to return objects/arrays from querys.

type Type ¶

type Type string

Type is a type alias for a string

const (
	// Token/character we don't know about
	Illegal Type = "ILLEGAL"

	// End of file
	EOF Type = "EOF"

	// Literals
	String Type = "STRING"
	Number Type = "NUMBER"

	// The six structural tokens
	LeftBrace    Type = "{"
	RightBrace   Type = "}"
	LeftBracket  Type = "["
	RightBracket Type = "]"
	Comma        Type = ","
	Colon        Type = ":"

	// Values
	True  Type = "TRUE"
	False Type = "FALSE"
	Null  Type = "NULL"
)

All the different tokens for supporting JSON

func LookupIdentifier ¶
