你遇到过的源代码中最好的注释是什么?


当前回答

许多年前,我接受了这份工作,为一个真正运行的项目提供支持 在Z80上的时间和组装(有其他方法做Z80吗??) 不管怎样,原作者是一个叫摩西的尼日利亚人。也许我应该 就此止步。 不管怎样,代码中到处都是这样的:

XRA A    ;MT

我花了好长时间才弄明白这是什么。指令本身没有其他作用 比清除蓄能器。这是一种狡猾的方法,尽管我不确定是否有 不管是不是优势。你可以这样做:

LDA 0

但也许

XRA A

节省一个字节之类的。is所做的是排他的或者是累加器本身。 当然,结果总是零。

回到MT -空(明白吗?)

这是我遇到的最好的。

/* Emits a 7-Hz tone for 10 seconds.
  True story: 7 Hz is the resonant frequency of a

  empirically in Australia, where a new factory
  generating 7-Hz tones was located too close to a
  chicken ranch: When the factory started up, all the
  chickens died.

整个函数非常棒(来自Linux的sunhme.c驱动程序,用于被Sun戏称为“快乐套餐”的网卡)。因为在那之前的卡片是“巨无霸”。明白了吗?明白了吗?)

                              void __iomem *tregs, int reg,
                              unsigned short value)

    if (!(hp->happy_flags & HFLAG_FENABLE)) {
            happy_meal_bb_write(hp, tregs, reg, value);
            return;
    }

    /* Would you like fries with that? */
    hme_write32(hp, tregs + TCVR_FRAME,

    while (!(hme_read32(hp, tregs + TCVR_FRAME) & 0x10000) && --tries)
            udelay(20);

    /* Anything else? */
    if (!tries)
            printk(KERN_ERR "happy meal: Aieee, transceiver MIF write bolixed\n");

    /* Fifty-two cents is your change, have a nice day. */

}

我经历了一个睡眠不足的编程过程,开始只写引用自《搏击俱乐部》的评论。

多年后,我仍然在浏览代码,发现了一条让我发笑的评论。大多数只是随机的想法。然而,我确实保持我的评论行比率相当好!

在几年前编写Perl时,我在顶部和底部添加了这些注释:

# <magic type="voodoo">

...

# </magic>

下一个研究它的人在Perl中并不是那么热门,他花了一段时间搜索文档,看看“魔法”和“巫毒”是怎么做的。从那以后,我试着添加更多有用的评论……
