编译原理基于antlr的编译器

基于antlr的编译器，可以实现swift转js的翻译操作，具体环境为安装antlr插件的IDEA中

import org.antlr.v4.runtime.ParserRuleContext;

import java.util.List;

public class AssignmentUtil {

    static public String augment（String code Instance type ParserRuleContext originalCtx Visitor visitor） {

        boolean isCopied =
            type.definition.cloneOnAssignmentReplacement != null && type.definition.cloneOnAssignmentReplacement.get（visitor.targetLanguage） &&
            !WalkerUtil.isDirectDescendant（SwiftParser.Literal_expressionContext.class originalCtx） &&
            !code.startsWith（“new “）;

        if（isCopied） {
            code = visitor.targetLanguage.equals（“ts“） ? “_.clone（“ + code + “）“ : “new “ + type.targetType（visitor.targetLanguage true false） + “（“ + code + “）“;
        }
        return code;
    }
