Functions ¶

func Search ¶

func Search(expression string, data interface{}) (interface{}, error)

Search evaluates a JMESPath expression against input data and returns the result.

Types ¶

type ASTNode ¶

type ASTNode struct {
	// contains filtered or unexported fields
}

ASTNode represents the abstract syntax tree of a JMESPath expression.

func (ASTNode) PrettyPrint ¶

func (node ASTNode) PrettyPrint(indent int) string

PrettyPrint will pretty print the parsed AST. The AST is an implementation detail and this pretty print function is provided as a convenience method to help with debugging. You should not rely on its output as the internal structure of the AST may change at any time.

func (ASTNode) String ¶

func (node ASTNode) String() string

type Lexer ¶

type Lexer struct {
	// contains filtered or unexported fields
}

Lexer contains information about the expression being tokenized.

func NewLexer ¶

func NewLexer() *Lexer

NewLexer creates a new JMESPath lexer.

type Parser ¶

type Parser struct {
	// contains filtered or unexported fields
}

Parser holds state about the current expression being parsed.

func NewParser ¶

func NewParser() *Parser

NewParser creates a new JMESPath parser.

func (*Parser) Parse ¶

func (p *Parser) Parse(expression string) (ASTNode, error)

Parse will compile a JMESPath expression.

type SyntaxError ¶

type SyntaxError struct {
	Expression string // Expression that generated a SyntaxError
	Offset     int    // The location in the string where the error occurred
	// contains filtered or unexported fields
}

SyntaxError is the main error used whenever a lexing or parsing error occurs.

func (SyntaxError) Error ¶

func (e SyntaxError) Error() string

func (SyntaxError) HighlightLocation ¶

func (e SyntaxError) HighlightLocation() string

HighlightLocation will show where the syntax error occurred. It will place a "^" character on a line below the expression at the point where the syntax error occurred.
