你遇到过的源代码中最好的注释是什么?
当前回答
I don't have the code to share, but imagine this scenario. About a month or two after our Linux Sys Admin left for greener pastures, I had the pleasure of opening a shell script he'd written. I can't recall why I needed to edit it, but that's not what matters. What's important is that the script was about 40 lines long. I scrolled past the commenting (of which there were 37 lines) to reach the actual working code (3 lines). The code was great, but I was curious - why 37 lines of commenting? So, I scrolled to the top and proceeded to read. To my surprise, the commenting was a rap about what the three lines of code did and how to change it. The best part - it was a partial rip off of Nothing But A G Thing by Dr. Dre and Snoop D O DOUBLE G. Thanks Brian!

在一些非常蹩脚的vb代码(我知道这都是蹩脚的,但),我发现这是一个空的if控制块中的注释,它说:
If bFound Then
'I love it when I write kick ass code like this
Else

// TODO - Comment this function
这是我们在前雇主购买的智能卡产品中发现的唯一一条评论。一群荷兰密码学博士写的嵌入式C语言和汇编程序
// echt halmaal gek - no way!
(它的意思是“真的完全愚蠢”……这对我们也没有帮助)
从《雷神之锤III》的资料中,我在一些随机的帖子中偶然发现了这一点。该文件的完整源代码可以在这里找到。这是一种非常快速的求平方根倒数的方法。至于最好的评论呢?当然,这是一种常见的方法,但考虑到它附着在直线上,它的神奇之处在于它的伟大之处。
float Q_rsqrt( float number )
{
long i;
float x2, y;
const float threehalfs = 1.5F;
x2 = number * 0.5F;
y = number;
i = * ( long * ) &y; // evil floating point bit level hacking
i = 0x5f3759df - ( i >> 1 ); // what the fuck?
y = * ( float * ) &i;
y = y * ( threehalfs - ( x2 * y * y ) ); // 1st iteration
// y = y * ( threehalfs - ( x2 * y * y ) ); // 2nd iteration, this can be removed
#ifndef Q3_VM
#ifdef __linux__
assert( !isnan(y) ); // bk010122 - FPE?
#endif
#endif
return y;
}
不是注释,而是属性

还有一个是我在IHttpHandler的实现中看到的
//What is this?
public bool IsReusable
{
get{return false;}
}
