Types

type InputLex

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

func NewInputLex

func NewInputLex(input io.ByteScanner, debug bool) *InputLex

func (*InputLex) Error

func (l *InputLex) Error(s string)

func (*InputLex) Errors

func (l *InputLex) Errors() int

func (*InputLex) Lex

func (l *InputLex) Lex(lval *InputSymType) int

func (*InputLex) Reduced

func (l *InputLex) Reduced(rule, state int, lval *InputSymType) (stop bool)

Reduced is hook for recording a reduction. https://godoc.org/modernc.org/goyacc Optionally the argument to yyParse may implement the following interface: Reduced(rule, state int, lval *yySymType) (stop bool) // Client should copy *lval.

type ParserResult

type ParserResult struct {
	Root           []node.Node
	LineNumbers    map[string]node.LineNumber // used by GOTO GOSUB etc
	LibReadData    bool
	LibGosubReturn bool
	LibMath        bool

	CountGosub     int
	CountReturn    int
	CountWhile     int
	CountWend      int
	CountIf        int
	FuncTable      map[string]node.FuncSymbol
