正则表达式来解析C ++枚举 [英] Regex to parse C++ enum

问题描述

如何构造正则表达式来解析C ++枚举？
我试过的枚举看起来像

How can a regular expression be constructed to parse C++ enums? The enums I tried on looked like

enum Temperature
{
    C = 0,
    F=1,     // some elements are commented
    R,       // most elements are not gived a value
    K        // sometimes the last element is succeeded by a comma
} temperature;

// different indent style is used
enum Depth {
    m = 0,
    ft = 1,
} depth;

我尝试了几个简单的模式，但没有一个足以覆盖上述所有情况。

I tried several simple patterns but none is general enough to catch all cases above.

任何可以帮助我的regexp向导？

Any regexp wizard who can help me?

编辑：澄清，我想要的名称和价值，例如C和0。

to clarify, I want the name and value, e.g. C and 0.

推荐答案

这是有挑战性的:)下面是我能想出来的最好的。假设它被赋予只是{和} 之间的文本，它会捕获所有名称和相应的值：

That was challenging :) Below is the best I could come up with. Assuming it is given just the text between { and } it captures all names and corresponding values:

/(\w+)\s*(?:=\s*(\d+)|)\s*,?\s*(?:(?:\n|$)|\/\/.*?(?:\n|$)|)/
