问题描述

我正在尝试在 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包含 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时，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，但当我保存它时，它什么也没做.

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

我环顾了整个互联网，找到了一些我拼凑起来的资源，并通过反复试验找到了解决方案.下面是我在我的几台机器上使用的指南，用于在 Eclipse 中设置 ANTLR 4 IDE.我想我应该在这里分享它并为其他人省去 Google 搜索数小时的麻烦(希望如此)

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)

    4. Click Install
    5. Let the installer finish clicking ok if it prompts and restart Eclipse

  • 获取antlr-4.x-complete.jar的副本

  • Obtain a copy of antlr-4.x-complete.jar

    1. 从这里
      2. 下载文件
    2. 把它保存在你会记得的地方

    • 创建 ANTRL 4 项目

    我在这里找到了大部分信息，剩下的就是阅读错误和猜测

    I found most of this information here, the rest was reading errors and guessing

    1. 转到<代码>文件>新项目项目
    2. 展开General 选项卡 并选择ANTLR 4 Project(如果您没有看到此内容，请参阅设置的第 4 步)
    3. 点击Next，为项目命名并点击Finish
    4. 项目完成后，右键单击该项目，然后单击Properties
    5. 转到Project Facets 并单击Convert to faceted form...(如果您没有看到此内容，请参阅设置的第 3 步)
    6. 检查 Java 项目方面并单击 Apply(如果您没有看到此内容，请参阅设置的第 3 步)
    7. 点击OK，让解决方案重建，再次打开属性
    8. 进入Java Build Path，点击Source标签
    9. 点击 Add Folder... 并检查 Project >目标 >生成源 >antlr4，点击OK
    10. 点击库标签
    11. Add External JARs...，找到antlr-4.x-complete.jar的副本，点击Open

    16. 点击Apply，点击Yes重建，点击OK退出属性
    1. Go to File > New Project > Project
    2. Expand the General Tab and select ANTLR 4 Project (if you don't see this see step 4 of setup)
    3. Click Next, give the project a name and click Finish
    4. Once the project is complete right click the project and click Properties
    5. Go to Project Facets and click Convert to faceted form... (if you don't see this see step 3 of setup)
    6. Check the Java project facet and click Apply (if you don't see this see step 3 of setup)
    7. Click OK, let the solution rebuild, open the properties again
    8. Go to Java Build Path, click the Source tab
    9. Click Add Folder... and check Project > target > generated-sources > antlr4, click OK
    10. Click the Libraries tab
    11. Add External JARs..., find your copy of antlr-4.x-complete.jar, click Open
    12. Go to ANTLR 4 > Tool, click Apply if a pop-up appears
    13. Check Enable project specific settings
    14. Click Add, find your copy of antlr-4.x-complete.jar, click Open
    15. Check 4.x
    16. Click Apply, click Yes to rebuild, click OK to exit the properties

    测试

    使用以下代码创建一个新类并尝试运行.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
    }
}

    注意事项

    1. 如果您在尝试进入 ANTLR 4 > 时看到错误工具检查你的Xtext版本，2.8.0导致工具窗口出错
    2. 在第 8 步中，如果您更改了 ANTLR 生成的目录，请使用该目录

    3. 如果您注意到您添加到 ANTLR 4 > 的 ANTLR 版本工具 >Distributions 消失了，这似乎没问题

    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

    • 检查您的构建输出以查看它使用的是什么工具，即使它消失了，它仍应使用您添加的 JAR.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
