Question

我在语法文件中遇到问题我在使用括号后突出显示方法调用的地方，好像它们是类型/类一样。

enter image description here

我找到了责任界：

syn match csClass contained       /\<[A-Z][a-z]\w\+/ nextgroup=csGeneric

证明如果我从此群组中删除csClass，我就不会突出显示图片中突出显示的方法：

syn region csEnclosed start="(" end=")" contains=csConstant, csType, csString, csVerbatimString, csCharacter, csNumber, csIface, csClass

这里是完整的cs.vim文件：

我想我是否可以参加csClass比赛并尝试告诉它不应该以点开头。＆＃39;它应该解决它，对吗？但我不熟悉vim的正则表达式（我使用常规正则表达式）。我试过这个：

syn match csClass contained       /^[^\.]\<[A-Z][a-z]\w\+/ nextgroup=csGeneric

意图是否定.（不应该以{{1}}开头），但它不起作用，它会禁用所有类突出显示。

实现这一目标的正确方法是什么？

非常感谢帮助！

Answer 1

您可以使用

/[^.]\<[A-Z][a-z]\w\+/

由于此字符串可以出现在一行的任何位置，因此我们不需要^字符串开头的锚点。

否定字符类[^.]匹配任何字符，但字符点（不需要在字符类中转义）。

所以，整个正则表达式意味着：

[^.] - 除字面点之外的任何字符
\< - 开始字边界（注意VIM样式正则表达式）
[A-Z] - 1个英文大写字母
[a-z] - 1个英文小写字母
\w\+ - 一个或多个字母数字字符（注意VIM-style转义量词：

\+匹配前面一个或多个字符...

）

<强>更新：

根据@ lcd047的评论，您可以使用\zs作为后备替代品：

/[^.]\zs\<[A-Z][a-z]\w\+/

来自VIM Wiki：

\zs在任何位置匹配，并在那里设置匹配的开始：下一个字符是整个匹配的第一个字符。   ...
实施例：
  /^\s*\zsif
      匹配行开头的“if”，忽略空格。
可以多次使用，最后一次遇到匹配       使用分支。
