你遇到过的源代码中最好的注释是什么?

这比你在许多评论标题中看到的可怕的法律通知和免责声明要好得多。从SQLite。

/*

**    May you do good and not evil.
**    May you find forgiveness for yourself and forgive others.

I was doing a database in Access, very simple thing - at least it was supposed to be at the start or I would have done it in Delphi. The client wanted to be able to get the customer info out of the database but they would not enter enough information to reliably identify the customer. I told them to use the phone number as the key as each customer (the way they worked, not for everyone) would have a different number. After a few frantic calls from them, (It's not working we can't enter the customer) I discovered that they were too lazy to look up the phone numbers from their old system and were trying to enter all the numbers they did not know as "n/a". In trying to sort this out for them I ended up with a lot of checking loops in the code and had the comment beside one outcome "This should never be reached if they do what they are supposed to do!!!!!!!!!"

他们还曾经问过我:“即使我们输入了错误的地址,我们如何才能找到正确的客户?”而这一切都是为了花生。

// barcore.cpp - MFC

//.....
HBRUSH CControlBar::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
    LRESULT lResult;
    if (pWnd->SendChildNotifyLastMsg(&lResult))
        return (HBRUSH)lResult;     // eat it

//......

// Eat it - just like eat this.

这个我在Python 2.5的“twisted”包中找到的(文件是tcp.py在第371行)

# Limit length of buffer to try to send, because some OSes are too
# stupid to do so themselves (ahem windows)
return self.socket.send(buffer(data, 0, self.SEND_LIMIT))

在一个项目中,我们有一个依赖ppwlib,当时它的FreeBSD端口有点糟糕,所以我不得不从源代码手动构建它。但它并没有立即起作用,我不得不研究代码;有一些复杂的类层次结构,部分代码是由宏生成的,其父类声明以它们开始

// The root of all evil ... umm classes

我经常看到这种情况:

// TODO make this work
