在EmEditor的正则表达式查找和替换中，能否实现数学计算？

可以用以下示例内容进行测试：

需要用支持10个以上分组的19.1以上的版本才行
Version 19.1 新增特性使用以下格式为超过 9 个的向后引用添加了正则表达式支持：\k<10>，\k<11>，\k<12>，…。如果用作替换表达式，则也可用以下格式：$10，$11，$12，…。
好像使用JavaScript语法进行替换，可以执行加减乘除。不过我不懂JavaScript语法
2020.7.17 我自己找到解决方案了，虽然不太完美，无法一次完成，执行完上述语句后，再接着执行 ^(.*?),(\d+?),(\d+?),替换为\J "\1," + (\2 + \3) + "," 即可
我也想问，有时候还是会遇到需要计算的情况，不过正则这样的标记语言应该不支持，没见过相关运用实例，所以遇到需要运算的情况我都会想办法转移到Excel中去 比较自然的方法是用Python之类的程序实现。一般的正则表达式没有对引用结果再计算的功能，EmEditor的 \J 实现了JavaScript表达式的求值，可以参考帮助手册的 How to - Search - Replacement Expression Syntax。除了简单的四则运算，主要涉及字符串方法的使用，可以参考MDN这个页面：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String。完全不去了解JavaScript是不现实的。 Vim就可以很容易实现，例如：
计算如下结果：
12*33
35*99
使用命令：
:%s/\(\d\d\)\*\(\d\d\)/\=submatch(1)*submatch(2)/
输出：
396
3465

根据你的提示，我找到解决方法了
