问题描述

我正在Eclipse Luna（4.4）上安装 ANTLR 4 IDE 。我已经从Marketplace安装了它，但我不知道如何创建一个具有ANTLR 4 Lexer / Parser的项目。

I'm trying to install the ANTLR 4 IDE on Eclipse Luna (4.4). I've installed it from the Marketplace but I have no idea how to create a project that has an ANTLR 4 Lexer/Parser in it.

当我去创建一个新项目我没有看到ANTLR 4的任何选项。我尝试创建一个.g4文件，它在编辑器中打开，但当我保存它不会做任何事情。

When I go to create a new project I don't see any options for ANTLR 4. I tried creating a .g4 file and it opens in the editor but when I save it doesn't do anything.

推荐答案

我环顾了互联网，发现了一大堆资源，我拼凑在一起，通过反复试验找到了解决方案。
以下是我在几台机器上使用的指南，以便在Eclipse中获得ANTLR 4 IDE设置。我想我应该在这里分享一下，拯救别人Google搜索几个小时的麻烦（希望）

I looked around all over the internet and found a handful of resources that I cobbled together and found a solution by trial and error. Below is a guide that I've used on a few of my machines to get ANTLR 4 IDE setup in Eclipse. I figured I should share it here and save others the trouble of Google searching for hours (hopefully)

    测试

    使用以下代码创建一个新类，然后尝试运行。在控制台中写入 Hello there 和 Ctrl + z 将EOF发送到输入流

    Create a new class with the following code and try running. In the console write Hello there and Ctrl + z to send EOF to the input stream

    import org.antlr.v4.runtime.*;
import org.antlr.v4.runtime.tree.*;
public class HelloRunner 
{
    public static void main( String[] args) throws Exception 
    {

        ANTLRInputStream input = new ANTLRInputStream( System.in);

        HelloLexer lexer = new HelloLexer(input);

        CommonTokenStream tokens = new CommonTokenStream(lexer);

        HelloParser parser = new HelloParser(tokens);
        ParseTree tree = parser.r(); // begin parsing at rule 'r'
        System.out.println(tree.toStringTree(parser)); // print LISP-style tree
    }
}

    笔记


    1. 如果您尝试进入 ANTLR 4>工具检查您的Xtext版本，2.8.0在工具窗口中导致错误

    2. 在步骤8中，如果您更改了ANTLR生成的目录来源该目录

    3. 如果您注意到您已添加到 ANTLR 4>的ANTLR版本工具>分发消失，这似乎是好的

    1. If you see an error when you try to go into ANTLR 4 > Tool check your Xtext version, 2.8.0 causes an error in the tool window
    2. In step 8, if you've changed the directory ANTLR generates it's sources use that directory

    3. If you notice that the version of ANTLR you've added to ANTLR 4 > Tool > Distributions disappears this seems to be ok


    • 检查你的构建输出，看看它使用什么工具，它应该还使用你添加的JAR，即使它消失了。这是我的样子：

    ANTLR工具v4.5（C：\JavaLib\antlr -4.5-complete.jar）
    Hello.g4 -o C：\Users\username\workspace\project\target\generated-sources\antlr4 -listener -no-visitor -encoding UTF -8
