Hi Forum,
we were just messing a bit around in the german purebasic forum,
and found SUDDENLY this .. comic.. mistake..
watch the amount of compilerendif / compilerif - s..
Code: Select all
Macro If_Home_is_defined
CompilerIf ((~Defined(home,#PB_Constant)) & %00000001)
EndMacro
Macro then_write_hello
Debug "hallo"
EndMacro
Macro and_go_Home
CompilerEndIf
EndMacro
; ------------------------------------------------------------
; ----DELETE THIS CONSTANT to see the MIRACLE --------------
; ------------------------------------------------------------
#home = 1
; ----
If_Home_is_defined
then_write_hello
and_go_Home
CompilerEndIf
Amazing, right?
bug or not?
merry christmas and a happy new year
-walker
on purebasic 4.51 *86 windows 7 etc..

This is correct. Code between CompilerIf and CompilerEndIf is not compiled, so 'and_go_Home' never gets expanded. There is just one CompilerEndIf.

Not a bug. Though a bit unexpected
None of the code between CompilerIf / CompilerEndIf seems to be processed, including any macros...
This behaves the same:
Code: Select all
Macro x_compilerendif
CompilerEndIf
EndMacro
;
#home = 1
;
CompilerIf ((~Defined(home,#PB_Constant)) & %00000001)
Debug "hallo"
x_compilerendif
CompilerEndIf
And this shows what happens:
Code: Select all
Macro x_compilerendif
CompilerEndIf
EndMacro
;
#home = 1
;
CompilerIf ((~Defined(home,#PB_Constant)) & %00000001)
Debug "hallo"
x_compilerendif

Damn Axe.. we say in bavaria.. (verdammte Axt..)
so compilerif has a higher priority than a macro o.O...
I would like to choose the priority.. well.. in this case ^^
ok, so thanks for helping again
and have a good flush into the next year

I think "Happy New Year" is what you want to say. To me this sounds more like being on the toilet.

Something which also needs to be taken care of... otherwise it will be a new year but not a happy one
