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 {}.

Too much whitespace/not enough whitespace. The "Great Debate" goes on.
Some programmers get paid by LOC, so they're induced to spread things out. Some programmers like to show how smart they are, so they try to condense everything to one line of cryptic functions. Other programmers heard "this" is the right way to do it.
For me, the key is "consistency". I want my code and all my programmers' code to look identical. It should be totally transparent who wrote the code. And the code needs to be clear, quickly comprehensible and understandable, yet concise.
I don't want to spend my time figuring out what John Doe was doing and maybe miss some key element when I'm under pressure to fix a problem or develop a new capability.
I tell my programmers that "I was around long before you came and I will be around long after you leave. Do it my way because I will have to maintain it later."
I just had to work on a one-liner script from another company that incorporated at least 12 function calls. Took me the better part of a week to figure out where the bug was. Yes it looked slick, but a week wasted is two weeks lost.
That's my thoughts--clear, comprehensible, concise.

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.

it doesn't make anything easier to read, and it definitely makes things harder to maintain.

Chris, you can't BS me, come on man. You honestly expect me to buy that not using brackets for a single-line if condition makes code harder to maintain? Seriously? Where's the joke icon?

Sure it's easy, until another developer adds a second line and forgets to add brackets.
I've been working in some source code that didn't use brackets for single statements. I introduced a few bugs by not adding them when I had to and I've been wondering more than once if the original developer REALLY meant not to add brackets....
if (condition)
DoThis();
else
DoThat();
DoAnotherThing(); is really weird to look at and at the very least makes you wonder if it was intended...
Especially if DoAnotherThing(); isn't properly in/outdented!

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.

It's really very much worth it. Look at it this way, if (it prevents a subtle bug from going into production (and dependent on your internal processes that chance may be a considerable risk)) { you may have saved that company downtime or wrong data and dependent on the size of that company a whole lot of money! } else { you just scroll a bit extra (it's negligable) and no one gets hurt... }

If the new guy screws up I'm the one responsible and I can get to fix whatever he broke, so that joke's on me

Not being able to see your code as a whole can also cause much harder to spot subtle bugs as well. Still not worth the trade off.
Besides, you're forgetting this[^].

Your automated tests should prevent a subtle bug even making it into the testing environment.

It's 2014, who cares how long the code file is. It's easier to read with the extra {}, it's easier to maintain with the extra {}. The only downside is typing extra {}. Don't you get paid per line anyway??
|
|

I care. Being able to see more at a glance is nice. It's also less convoluted when it's a simple statement. And I don't get paid per line, nobody does. I get paid to deliver a product that's useful. Nobody cares about line count except other nerds / devs.

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.

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.

I am currently working on a system where most of the software was written in C in the early 1980s. It is formatted so badly that stuff like
if (condition)
DoThis();
else DoThat();
DoAnotherThing();
is not uncommon at all. Add to that, there is no consistent use of tabs vs. spaces, no consistent tab stops, no naming conventions.
Honestly, use the braces or don't, just be consistent, dammit. Proper indentation is far more valuable than brace usage; don't use TAB for indentation, and do stuff the same way, every damn time.

it certainly is harder to maintain.
i can't count how many times i've had to fix something in code that only uses brackets when one or more statements are being controlled. so you get stuff like:
for (i=0;i<10;i++)
for (x=0;x<10;x++)
if (xyz) foo()
else for (z=0;z<10;z++)
bazinga();
bar();
and then you have to spend precious brain wattage figuring out that bar(); has nothing to do with any of the rest of it.
this isn't 1967, 3 bytes for a bracket and an CR/NL isn't going to run you out of punch cards. make the code readable!

The rule that I have is that you omit the braces iff the statement is a simple single line. Also, if either branch needs braces then both get them, and loops always have braces.
|
|

but that's the start of the problem!
someday, someone is going to have to come along and add some more logic in that if, and you've just forced them to do the work you should've done the first time!
