你遇到过的源代码中最好的注释是什么?


当前回答

大约1997年,Netscape网络浏览器的UNIX风格的源代码:

/* HP-UX sucks wet farts from dead pigeons' asses */

不幸的是,在Moz开源之前,这些珍珠被移除了……

其他回答

// I dedicate all this code, all my work, to my wife, Darlene, who will 
// have to support me and our three children and the dog once it gets 
// released into the public.
# dont question, i just felt like throwing some globals in
# this is actually quite pointless as youll soon see

稍后在代码中

#draw the circles (complicated)...dont question

更晚…

# complicated process of drawing the circles in a
# somewhat symmetrical, 3-d pattern
# dont question again

甚至以后……

# will determine if user clicks on die
# i determined these values...dont worry about them

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;
}
catch (Domain.ConcurrencyException)
{
    // somebody changed it between the time we loaded it and now.
    // weird, huh?
}
