antl . gunt . interp有哪些选项?如何打开其详细选项

Question

我当然错了，但是antlr的unit似乎没有给用户选择。

bash-3.2$ java org.antlr.gunit.Interp --help
Exception in thread "main" java.io.FileNotFoundException: --help (No such file or directory)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(FileInputStream.java:120)
    at java.io.FileInputStream.<init>(FileInputStream.java:79)
    at org.antlr.runtime.ANTLRFileStream.load(ANTLRFileStream.java:59)
    at org.antlr.runtime.ANTLRFileStream.<init>(ANTLRFileStream.java:47)
    at org.antlr.runtime.ANTLRFileStream.<init>(ANTLRFileStream.java:42)
    at org.antlr.gunit.Interp.main(Interp.java:62)
bash-3.2$ 

特别是，我想打开详细选项，否则它告诉真的很少当错误发生。
您知道如何打开它的详细/调试选项吗?

假设您正在使用antlr3，查看GitHub (https://github.com/antlr/antlr3/blob/master/gunit/src/main/java/org/antlr/gunit/Interp.java)上的源代码，您是正确的，没有详细选项。

验证测试失败原因的一种方法是在调试模式下通过AntlrWorks运行输入，这样您就可以看到匹配的规则。
