Yacc equivalent for Java
提问by vuzun
I'm working on a compiler design project in Java. Lexical analysis is done (using jflex) and I'm wondering which yacc-like tool would be best(most efficient, easiest to use, etc.) for doing syntactical analysis and why.
我正在从事 Java 编译器设计项目。词法分析已经完成（使用 jflex），我想知道哪种类似 yacc 的工具最适合（最有效、最容易使用等）进行句法分析以及为什么。

If you specifically want YACC-like behavior (table-driven), the only one I know is CUP.
如果你特别想要类似 YACC 的行为（表驱动），我知道的唯一一个是CUP。
In the Java world, it seems that more people lean toward recursive descent parsers like ANTLRor JavaCC.
在 Java 世界中，似乎越来越多的人倾向于使用递归下降解析器，如ANTLR或JavaCC。
And efficiency is seldom a reason to pick a parser generator.
效率很少成为选择解析器生成器的理由。

In the past, I've used ANLTR for both lexer and parser, and the JFlex homepage says it can interoperate with ANTLR. I wouldn't say that ANTLR's online documentation is that great. I ended up investing in 'The Definitive ANTLR reference', which helped considerably.
过去，我将 ANLTR 用于词法分析器和解析器，并且 JFlex 主页说它可以与 ANTLR 互操作。我不会说 ANTLR 的在线文档那么好。我最终投资了 'The Definitive ANTLR reference'，这有很大帮助。

You can use it go generate Java code.
您可以使用它来生成 Java 代码。

Another option would be the GOLD Parser.
另一种选择是GOLD Parser。
Unlike many of the alternatives, the GOLD parser generates the parsing tables from the grammar and places them in a binary, non-executable file. Each supported language then has an engine which reads the binary tables and parses your source file.
与许多替代方案不同，GOLD 解析器根据语法生成解析表，并将它们放在一个二进制的、不可执行的文件中。每个受支持的语言都有一个引擎，可以读取二进制表并解析您的源文件。
I've not used the Java implementation specifically, but have used the Delphi engine with fairly good results.
我没有专门使用 Java 实现，但使用过 Delphi 引擎并取得了相当不错的结果。

There is also jacc.
还有jacc。
Jacc is about as close to yacc as you can get, but it is implemented in pure java and generates a java parser.
Jacc 与 yacc 尽可能接近，但它是用纯 Java 实现的，并生成一个 Java 解析器。
It interfaces well with jFlex
它与 jFlex 接口良好
