Types ¶
type ASTNode ¶
type ASTNode struct {
NodeType astNodeType
Value interface{}
Children []ASTNode
}
ASTNode represents the abstract syntax tree of a JMESPath expression.
func (ASTNode) PrettyPrint ¶
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.
type Lexer ¶
type Lexer struct {
// contains filtered or unexported fields
}
Lexer contains information about the expression being tokenized.
type Parser ¶
type Parser struct {
// contains filtered or unexported fields
}
Parser holds state about the current expression being parsed.
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.
type TokType ¶
type TokType int
const ( TOKUnknown TokType = iota TOKStar TOKDot TOKFilter TOKFlatten TOKLparen TOKRparen TOKLbracket TOKRbracket TOKLbrace TOKRbrace TOKOr TOKPipe TOKNumber TOKUnquotedIdentifier TOKQuotedIdentifier TOKComma TOKColon TOKPlus TOKMinus TOKMultiply TOKDivide TOKModulo TOKDiv TOKLT TOKLTE TOKGT TOKGTE TOKEQ TOKNE TOKJSONLiteral TOKStringLiteral TOKCurrent TOKRoot TOKExpref TOKAnd TOKNot TOKVarref TOKAssign TOKEOF )
