Ok, you have a good point with that, but it's still not worth the trade off of having really extra long files / routines. Besides, it gives you something to spot the new guys with so you can give them a hard time.

Who cares how long the files are? They aren't being printed on paper (hopefully), and scrolling is not so hard. Setting a trap for junior programmers that introduces a bug is not responsible programming. If you do that, you are responsible for the bug, not the newbie, and you should be "given a hard time" for compromising the code base just to be a jerk.

I'm not lazy, but I'll still use the latter. There's no point in always having to use a bracket so I don't, unless it makes things easier to read. Which in your example it doesn't. Wasting space just makes a source code file longer anyway and harder to navigate. Concise wins, unless it's hard to read.

I both agree and disagree. My personal coding style is:
if (expr) {
doSomething();
}
else {
doAnotherThing();
}I like using the braces so that adding an extra bit of logic to the execution block won't inadvertently change the program flow, and at the same time placing the opening brace on the same line as the if... and the else statements compacts the code a bit. To me the advantage with compact code is that you can see more of the program logic in a single screen which means less time scrolling up and down trying to follow the program logic. For that reason, I'm ruthless in eliminating blank line whitespace except to visually offset functions or methods.

The trap isn't that hard to spot though. Seriously man, we're not talking about something difficult. It's just a peeve. We can debate, but that's all it is. Just a peeve. And my preference is that I'd rather see more of the file, because it's not that hard to spot.

As much as I'm not a fan of that (even in JavaScript), that makes more sense than:
if (expr)
{
doSomethingForOneLine();
}
else
{
doAnotherThingForOneLine();
}You're version is at least concise, and no matter what some may say on CP, concise is important. Less is more. Always will be.

Just for making that statement, you should be forced to a maintain decade-old Perl CGI system.

I, for example, would never write the code like that. I can write an if without the {}, but I always put an extra line break after the call. And seeing two lines after the if simply looks wrong.
if ((err = SSLHashSHA1.update(&hashCtx, &serverRandom)) != 0)
goto fail;if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0)
goto fail;
goto fail; // why the hell there's a line of code here? It is not important what it does, it looks wrong.if ((err = SSLHashSHA1.final(&hashCtx, &hashOut)) != 0)
goto fail;So, this kind of error is as ugly to me as this (in fact, even uglier as the excessive {} somewhat hide the problem):
if ((err = SSLHashSHA1.update(&hashCtx, &serverRandom)) != 0)
{
goto fail;
}if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0)
{
goto fail;
}
goto fail; // Doesn't this look wrong?if ((err = SSLHashSHA1.final(&hashCtx, &hashOut)) != 0)
{
goto fail;
}But developers can also commit these errors (and by simply taking a looks without reading the code, I don't spot anything wrong):
if ((err = SSLHashSHA1.update(&hashCtx, &serverRandom)) != 0)
{
goto fail;
}if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0)
{
goto fail;
} // Oh, it looks like an else is missing...
{
goto fail;
}if ((err = SSLHashSHA1.final(&hashCtx, &hashOut)) != 0)
{
goto fail;
}// So the code gets corrected to...
if ((err = SSLHashSHA1.update(&hashCtx, &serverRandom)) != 0)
{
goto fail;
}if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0)
{
goto fail;
}
else
{
goto fail;
}if ((err = SSLHashSHA1.final(&hashCtx, &hashOut)) != 0)
{
goto fail;
}Well, I won't write anything such as that either. But since this a real world example of infamous 'goto fail' bug obviously other people do. In general I'd say that none of your samples with braces would've passed my code review, but I admit your first sample should attract review attention as well, it'll probably will attract enough attention from any reviewer. Still I'd say that with braces style the code like that most probably would not leave the developer and will be fixed before review

Yeah true, you really need to be pedantic about a joke?

LOL, that looks exactly like T-SQL :)

I personally prefer this convention: if ((a cond b) conjunction (c cond d) conjunction // Additional conditions always on separate line (e cond f)) { // Always include opening brace do .... something } // Always closing brace Or } else { // Always closing brace..else..opening brace do .... something else } // Always closing brace The same conventions and principles apply to loops (for, while, etc.) and other conditionals. I strictly avoid NOT using braces under any circumstances. I want to be able to see a complete thought, i.e., a block of code, in one intact, obvious section. These are my thoughts based on years of chasing bugs, modifying other people's code, and having to debug somebody else's problem. Other people are welcome to use their own conventions, but I may not be able to help them efficiently. Just because I can do something doesn't mean I should do it.

Why are people so lazy? For example, how hard is it to
if (condition)
{
DoThis();
}
else
{
DoThat();
}as opposed to:
if (condition)
DoThis();
else
DoThat();Pedants :sigh:

Both are probably less hard than complaining about it. But other than that since it is legitimate syntax then it is legitimate syntax and nothing but a preference after that. Naturally if that is the most important problem facing you day to day or even one that even rises above the noise level in terms of problems you must work at an exceeding stellar place. I once worked a a place where the VP (most senior person in the entire site) would regularly take down the database through incorrect usage which would shut down the call center (several hundred employees) completely. Now that is a problem.

It's interesting that the older the programmer the more concision becomes important. :)
