Squirrel bug: return statement

[Michiel]

I ran into a bug recently: return statements where the return value is not on the same line as the statement, return null:

Code: Select all

class Test extends AIController {
	
	function Start() {
		AILog.Info("f1: " + f1());
		AILog.Info("f2: " + f2());
		AILog.Info("f3: " + f3());
	}
	
	function f1() {
		return "Hello, world!";
	}
	
	function f2() {
		return
			"Hello, world!";
	}
	
	function f3() {
		return "Hello, " +
			"world!";
	}
	
}

This prints:

Code: Select all

f1: Hello, world!
f2: (null : 0x00000000)
f3: Hello, world!

This is on the latest revision of the NoAI branch.

It's not a bug. In squirrel a statements ends with a semicolon or a newline. So you usually can't use multiline statements (f3() is an exception there because '+' requires something)

See http://squirrel-lang.org/doc/squirrel2.html#d0e656

Aha! That's what you get when you pick up the language from examples. I saw semicolons everywhere so it never registered they're optional. Thanks

It was surprising to everyone And it is _very_ annoying (lets face it, which sane language allows both \n and ';' to terminate commands .. it should be either one .

Couldn't agree more

So.. someone would need to nail together some new language that we can use instead of squirrel... but that would be like a bolt out of the blue, wouldn't it?

Dear me, here comes the puns!

Funny, I never realised that, and I thought I had read all the squirrel docs.

Interesting to know, and insane, I agree!

javascript

but then again... "javascipt" and "sane"...
