Visual studio code 非固定字符长度后的文本匹配查找

我正在为Visual Studio代码不支持的编程语言编写语法突出显示。突出显示工作正常，但我在突出显示以下代码时遇到了一个问题：

pool[] Test1 t1;
pool[1] Test2 t2;
pool[10] Test3 t3;

我使用以下方式突出显示“池”一词：

它正在工作，但我想强调一下Test1、Test2和Test3

我唯一的想法是用消极的眼光看后面，就像这样：

(?<=pool\[\d*\]\s+)([A-Z])\w+

（？您可以使用捕获组。这里我捕获了3个组，但只为第2个组分配了一个范围

"storages": {
    "patterns": [{
        "match": "^(\w+\[\d*\])\s+(\w+)\s+(\w+);$",
        "captures": {
            "2": {
                "name": "storage.type.ceu"
            }
        }
    }]
},

非常感谢。这个解决方案非常有效。
(?=subexp)         look-ahead
  (?!subexp)         negative look-ahead
  (?<=subexp)        look-behind
  (?<!subexp)        negative look-behind

                     Subexp of look-behind must be fixed-width.
                     But top-level alternatives can be of various lengths.
                     ex. (?<=a|bc) is OK. (?<=aaa(?:b|cd)) is not allowed.

                     In negative look-behind, capturing group isn't allowed,
                     but non-capturing group (?:) is allowed.

"storages": {
    "patterns": [{
        "match": "^(\w+\[\d*\])\s+(\w+)\s+(\w+);$",
        "captures": {
            "2": {
                "name": "storage.type.ceu"
            }
        }
    }]
},
