코드 colorizer 오류

Question

내가

b.a := 7; 

내 문법과 같은 문을 구문 분석 문법을 쓰기 위해 노력하고 있어요 그것은 내가

을 구문 분석하려고 할 때 잘 작동

public class STGrammar : InterpretedLanguageGrammar 
{ 
    public STGrammar() : base(caseSensitive: false) 
    { 
     LanguageFlags = LanguageFlags.CreateAst; 

     # region Terminals 
     Terminal n = new NumberLiteral("number"); 
     Terminal v = new IdentifierTerminal("variable"); 
     KeyTerm assignment = ToTerm(":="); 
     KeyTerm left_paren = ToTerm("("); 
     KeyTerm right_paren = ToTerm(")"); 
     KeyTerm terminate = ToTerm(";"); 
     KeyTerm left_sq = ToTerm("["); 
     KeyTerm right_sq = ToTerm("]"); 
     KeyTerm dot = ToTerm("."); 
     #endregion Terminals 

     #region Nonterminals 
     NonTerminal actionBlock = new NonTerminal("actionBlock", typeof(ActionBlock)); 
     NonTerminal assignmentExpr = new NonTerminal("assignmentExpr", typeof(AssignmentStNode)); 
     NonTerminal arrayOrStruct = new NonTerminal("arrayOrStruct", typeof(ArrayNode)); 
     NonTerminal arrayOrStructRHS = new NonTerminal("arrayOrStructRHS", typeof(AstNode)); 
     NonTerminal arrayOrStructRHSs = new NonTerminal("arrayOrStructRHSs"); 
     NonTerminal comparatorExp = new NonTerminal("comparatorExpression", typeof(ExpressionNode)); 
     #endregion Nonterminals 

     #region BNFRules 
     actionBlock.Rule = 
      assignmentExpr + terminate 
      | arrayOrStruct + terminate 
      ; 
     assignmentExpr.Rule = 
      v + assignment + v 
      | v + assignment + n 
      | arrayOrStruct + assignment + v 
      | v + assignment + arrayOrStruct 
      | arrayOrStruct + assignment + arrayOrStruct 
      | arrayOrStruct + assignment + n 
      ; 
     arrayOrStruct.Rule = 
      v + arrayOrStructRHSs 
      ; 
     arrayOrStructRHS.Rule = 
      "." + v 
      | "[" + v + "]" 
      ; 
     arrayOrStructRHSs.Rule = 
      MakePlusRule(arrayOrStructRHSs, arrayOrStructRHS) 
      ; 

     this.Root = actionBlock; 

     #endregion BNFRules 

     MarkPunctuation(",", ";", "[", "]", ")", "(", "..", "."); 
     RegisterBracePair("(", ")"); 
    } 
} 

아래와 같습니다

b := 7;

임시 노드를 제외한 모든 비 터미널 노드에 대해 Ast 노드 유형을 추가해야합니다. 각 Ast 노드 클래스에서는 Init() 및 DoEvalute() 함수를 재정의합니다. 자세한 내용은 this discussion
