    The documentation clearly states that I need ANTLR. So, I downloaded the current version 3.0.1. There is no end-to-end AST file named .hpp. Do I need an upstream version (which one) or where does this file come from?

    What Is ANTLR?

    ANTLR (another language recognition tool) can bepowerful parser generator for reading, executing orAlso translate structured text from binary files. Often used for constructionLanguages, tools and frameworks. From a good grammar, ANTLR generatesA parser that in many cases can build and traverse parse trees.

    Okay, let’s create a simple math example. Building an AST is definitely overkill for such a task, and it’s also a great way to teach this principle.

    cannot open source file antlr/ast.hpp

    I’ll do it in C#, but the Java version will be more similar.

    Let’s start by writing an extremely simple math grammar for problems using:

    Grammar Mathematics;compileUnit    >> EOF operator    ;Expression    ! ! ! '('expr')' parenexpr number    | op=('+'|'-') expr #Unary expression    | left=expr op=('*'|'/') right=expr number infixExpr    | left=expr op=('+'|'-') right=expr # infixExpr    | func=ID '('expr')' number funcExpr    | value = NUMBER number numberexpression    ;OP_ADD: '+';OP_SUB: '-';OP_MUL: '*';OP_DIV: '/';NUMBER: [0-9]+ ('.' [0-9]+)? [+-]? ([ee][0-9]+)? ;ID: [a-zA-Z]+;Sun. . [ trn] -> channel (HIDDEN);

    To Quite a simple thing, we have one expr rule that handles many things (priority rules, etc.).

    Next, we define the most used AST nodes. They are completely individual, and you yourself can determine how to strive for them.

    cannot open source file antlr/ast.hpp

    internal abstract class ExpressionNodeinternal abstract degree InfixExpressionNode : ExpressionNode    User ExpressionNode Left get; together;    public right ExpressionNode get; together;Internal section AdditionNode: InfixExpressionNodeinner class SubtractionNode: InfixExpressionNodeinner class MultiplicationNode: InfixExpressionNodeInner Lesson DivisionNode: InfixExpressionNodeinner class NegateNode: ExpressionNode    public ExpressionNode InnerNode get; together;FunctionNode internal training class: ExpressionNode    client Func Get function; together;    Get the herd ExpressionNode argument; together;internal category NumberNode: ExpressionNode    get double social value; together;

    ANTLR generated CST nodes for us (MathParser.*Context classes). Now we need to convert them to support your AST nodes.

    This visitor is easy to learn and ANTLR provides the class MathBaseVisitor in the US, so we will work with him.

    inner class: buildastvisitor MathBaseVisitor{    public forward ExpressionNode VisitCompileUnit(MathParser.CompileUnitContext)            return visit(context.expr());         replace ExpressionNode VisitNumberExpr(MathParser.NumberExprContext)            returns a new NumberNode         NumberStyles.AllowExponent)        ;        public workaround VisitParensExpr(MathParser.ParensExprContext context expression node)            return visit(context.expr());        Override ExpressionNode completion VisitInfixExpr(MathParser.InfixExprContext)    {        InfixExpressionNode;        Control key (context.op.Type)        {            MathLexer.OP_ADD case:                node = new additional node();                Pause;            MathLexer.OP_SUB case:
