Functions

func EnableErrorVerbose

func EnableErrorVerbose()

EnableErrorVerbose enabled verbose errors from the parser

func Parse

func Parse(s *Scanner) (ast.Stmt, error)

Parse provides way to parse the code using Scanner.

func ParseSrc

func ParseSrc(src string) (ast.Stmt, error)

ParseSrc provides way to parse the code from source.

Types

type Error

type Error struct {
	Message  string
	Pos      ast.Position
	Filename string
	Fatal    bool
}

Error is a parse error.

func (*Error) Error

func (e *Error) Error() string

Error returns the parse error message.

type Lexer

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

Lexer provides interface to parse codes.

func (*Lexer) Error

func (l *Lexer) Error(msg string)

Error sets parse error.

func (*Lexer) Lex

func (l *Lexer) Lex(lval *yySymType) int

Lex scans the token and literals.

type Scanner

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

Scanner stores informations for lexer.

func (*Scanner) Init

func (s *Scanner) Init(src string)

Init resets code to scan.

func (*Scanner) Scan

func (s *Scanner) Scan() (tok int, lit string, pos ast.Position, err error)

Scan analyses token, and decide identify or literals.
