ANTLR JavaScript 目标 [英] ANTLR JavaScript Target

问题描述

我一直在使用 ANTLR 为带有 Java 目标的标记语言生成解析器 + 树语法，效果很好.现在我试图在 JavaScript 中获取目标以在我的 Web 浏览器中使用它.

但是，我无法找到有关如何执行此操作的任何好的文档.我在 ANTLR IDE 中使用 Eclipse，当我将语言指定为 JavaScript 时，出现以下错误.

此行有多个标记

• (10):内部错误:组 JavaScript 不满足接口 ANTLRCore:这些模板上的参数不匹配 [treeParser(grammar, name, scopes, tokens, tokenNames, globalAction, rules, numRules, bitsets, labelType, ASTLabelType, superClass, members, filterMode)]

• (10):内部错误:java.util.NoSuchElementException:没有这样的属性:模板上下文中的filterMode [treeParser]

如果有人能帮我解决这个问题，或者给我指点我可以阅读的有关使用 ANTLR 的 JavaScript 目标的材料，那就太好了.

谢谢

解决方案

将近 3 个月前发布到 GitHub 的 ANTLR4 的新 JS Lang 目标:

antlr/antlr4-javascript

它尚未集成到正式版本中，但您可能只需将其放入最新的 ANTLR4 代码库并自己重新编译 ANTLR.

I have been using ANTLR to generate a parser + tree grammar for a mark up language with Java target which works fine. Now I am trying to get the target in JavaScript to use it in my web browser.

However, I have not been able to locate any good documentation on how to go about doing this. I am using eclipse with ANTLR IDE, and when i specify the language as JavaScript, I get the following errors.

Multiple markers at this line

• (10): internal error: group JavaScript does not satisfy interface ANTLRCore: mismatched arguments on these templates [treeParser(grammar, name, scopes, tokens, tokenNames, globalAction, rules, numRules, bitsets, labelType, ASTLabelType, superClass, members, filterMode)]

• (10): internal error: java.util.NoSuchElementException: no such attribute: filterMode in template context [treeParser]

If anyone could help me out with this or point me to some material which I could read about the JavaScript target with ANTLR, it would be great.

Thanks

解决方案

There is a new JS Lang target for ANTLR4 that was posted to GitHub almost 3 months ago:

antlr/antlr4-javascript

It's not integrated into an official release yet, but you can probably just throw it into the latest ANTLR4 codebase and recompile ANTLR yourself.
