AutoIt3 syntax mania

[genius257]

So i do a lot of unusual stuff with AutoIt, and find weird syntax as a result...

I'll start off with this:

consolewrite("test"&Chr(65)Chr(65)Chr(65)&&&@CRLF); testAAA

Maybe it is an intentional feature of AutoIt, but i believe it is just a weird glitch in the parser.

Meaning any string concatenation can be moved to the end of string:

$x = 'a'"b"'c'&&
ConsoleWrite($x & @CRLF)

Tested with 3.3.16.1

Weird

$string = Chr(65)Chr(85)&1-+++-1-+++-1&&@crlf
consolewrite($String)

Is this working with the last AutoIt version? What about SciTE? Doesn't throw any compile or runtime error?

Yes, 3.3.16.1, outputs "AU3" in the console.

SciTE Lite is silent, dont know about full SciTE.

If running from full Scite, you need to add :

#AutoIt3Wrapper_Run_Au3Check=n

 

[Werty]

The "1-+++-1-+++-1" part has been like that for years, Try various combinations of "---++---------+----+--+" or whatever with some numbers.

The "Chr()Chr()&&" part I didnt know about.

Does this count?

I at least haven't seen it listed in the help file anyway. (Maybe missed it)

Local $bTest

$bTest = ConsoleWrite("Hi!" & @CRLF) = 5
ConsoleWrite($bTest & @CRLF)

Return Value: The amount of data written.

So ( 5 = 5 ) is True.

Here is another:

$x = 1 ? 1 : 0 : 0 : 0 : 0 : 0

Au3Check complains, but it works at runtime

The ternary expression will still work as expected.

And here is an undocumented feature i personally love ❤️ 

$t = DllStructCreate("INT a;INT b;INT c[3];")
; DllStruct values can used via dot notation
$t.a = 123
ConsoleWrite($t.a & @CRLF)
; But i recently discovered this also applies to indexed elements:
ConsoleWrite($t.c(2) & @CRLF)
$t.c(2) = 123
ConsoleWrite($t.c(2) & @CRLF)

And a silly one:

Keywords like Null and Default MUST be followed with a space, when followed by operators like & and +

$x = Null+1; 
ConsoleWrite($x&@CRLF)

 

test.au3 (76) : ==> Missing separator character after keyword.: 
$x = Null+1 
$x = Null^ ERROR

Au3Check will not detect this error.

I usually use spaces between operators keywords, etc, for a better reading, yet this one is ridiculous.

I could be mis-remembering, but I'm sure this was on the chopping block at some point years ago...

Can't find the thread now, but I think it was along the lines of reserving dot notation for object datatypes.

[Andreik]

I remember too that dot notation is not encouraged so it doesn't appear anywhere in the help file, yet it's used by many of us.

There is also an undocumented bug about this notation that one must be aware of :

$t.c(2) = 123
ConsoleWrite($t.c(2) & @CRLF)
$i = 2
$t.c($i) = 321  ; does not work
ConsoleWrite($t.c(2) & @CRLF)
$t.c(($i)) = 321  ; now works
ConsoleWrite($t.c(2) & @CRLF)

Thanks, I do understand that, but what I meant is I haven't seen any documentation on comparing two items and it returning a Boolean directly to a variable like that, without a If/Ternary. Perhaps it's just coding common-knowledge that I missed somewhere.
