Here's a Visual Studio trick:
To debug the if, make sure the text cursor is somewhere in the if condition and press F9.
To debug the method call after the if succeeded, make sure the text cursor is somewhere in the method call and press F9.
Happy Debugging

Imagine the if and the call are in the same line. Yet, the condition is false 99% of the time.
Also, the method being called is called from many other places.
If things are in two lines, simply put the breakpoint inside the if, not on the if line. If it is in the same line, you can't do that. Putting the breakpoint inside the method call will not help either, as it is called from many other places, so the best you can do is to create a conditional breakpoint.
I prefer to have things in two lines and put the breakpoint exactly where it is needed.

Me too, if you must omit the braces then it's best to put it on one line. That way you don't have to worry about someone coming along later, not paying attention, and doing this:
if (something)
DoA();
DoB();

That works fine until you get this in the code after all 
if ((err = SSLHashSHA1.update(&hashCtx, &serverRandom)) != 0)
goto fail;
if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0)
goto fail;
goto fail;
if ((err = SSLHashSHA1.final(&hashCtx, &hashOut)) != 0)
goto fail;
When I first saw that bug I got even more convinced see that my approach to braces everywhere as a must works better in the end.

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;
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;
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;
}
{
goto fail;
}
if ((err = SSLHashSHA1.final(&hashCtx, &hashOut)) != 0)
{
goto fail;
}
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

I don't care what way you do it as long as it is not:
if (something) {
DoA()
}
Yuck!
But seriously - if the biggest problem your project has is where people put or don't put the braces you are doing pretty good.

I agree with you. And I am actually the kind of person that when has to modify something like:

DoA();
DoB();

To only call a DoAB(), I will go there and kill the extra { and }. So, I have more work doing that, but I keep consistency.
So, it becomes:
if (something)
DoAB(); |
Are you serious? You re-factor and combine methods just so you can avoid braces and use a dangerous bad practice?
|
|
|
|

No, I don't refactor and combine methods... I was only giving an example. What's more probably is that I extract an entire block (with many calls) into a single method. But for the example I used two calls.

And why couldn't you write
if (condition)
{
this.DoThis();
}
else
{
this.DoThat();
}Now this code is totally unambiguous
Although I know some people who really hate this...

That's not good enough...
if
(
condition
)
{
this
.
DoThis
(
)
;
}
else
{
this
.
DoThat
(
)
;
}
It's not properly formatted until there's only one token per line.

Way back in my College days the Software Lecturer told us (the class) it wasn't possible to do the above. I proved her wrong by writing a short Pascal (I think) program with no returns all on one line, ah Youth

Quite. The maturity of a programming language may (in part) be calculated by how many newlines are required. A proper language requires none.

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

Perl is a scripting language; not a programming language.

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

No, but I really need to be demeaning of Perl.

Of course it is, or at least, it was. That's what we used to do when programming in APL. There were execution costs for each new line you used.

You guys need to investigate APL, a language described by one of my fellow students as "the ultimate in elegance"

Totally agree...but for a very spesific reason. I'm using a Braille display with a maximum of 40 chars per line, so it have a influence on my format preferences... 
Seriously though,
if (condition)
{
Action1();
}
else
{
Action2();
}
is my real preference, and there's a plus to that, whenever the situation change to have more than one statement for the if test, the person who has to change it doesn't have to remember to go and fill in the {}.
