任何类型的空格上的 JavaCC 词法错误 [英] JavaCC lexical error on any type of whitespace

问题描述

我清楚地在我的 SKIP 令牌中定义了 unicode 空白字符，如下所示:

I cleary have the unicode whitespace characters defined in my SKIP token like so:

    SKIP {
" "
| "\r"
| "\n"
| "\t"

}

但是，当我运行 Java CC 时，它会很好地解析所有标记，直到我遇到上述任何一个空格字符并抛出以下错误:

However, when I run Java CC it parses all the tokens fine until I hit any of the above mentioning white space characters and it throws the following error:

Exception in thread "main" prjct1.TokenMgrError: Lexical error at line 1, column 25.  Encountered: "\r" (13), after : "Random:Word:Here"

所以你可以看到它运行良好，直到它遇到\r".我用"、\n"和\t"得到同样的错误.有什么想法吗?谢谢

So as you can see it runs fine until it hits the "\r". I get the same error with " ", "\n", and "\t". Any thoughts? thanks

推荐答案

确保在 SKIP 和括号之间有一个冒号.

Make sure you have a colon between the SKIP and your bracket.

跳过:{""|富"|酒吧"}

SKIP: { " " | "foo" | "bar" }
