Use of conditional compilation !if with &&

[gus38]

Hello,

I'm trying to use the conditional compilation !if with boolean comparison && but it seems not working well.

My code :
!define SECTIONDEF 0x0001

!insertmacro CreateSection SECTIONDEF "SECTIONNAME" "SECIDX"

!macro CreateSection SecDef SecText SecIdx
!echo "secname = ${${SecDef}}"
!if ${${SecDef}} && 0x0008
Section "!${SecText}" ${SecIdx} ; comparison true
!else
Section "${SecText}" ${SecIdx} ; comparison false
!endif
SectionIn RO 1 2
!macroend

I change the value of SECTIONDEF, but it always pass thru the true section code.

Do you have any idea ?

Thank you and sorry for my bad english

What exactly are you trying to do? Double ampersand is a boolean operator not a binary operator. Your test only tells if both defines are not empty.

Yes, thank you.
I saw after posting this thread that it was only a boolean operator.
I have submitted a feature request on Sourceforge for a binary operator "&", in order to test only a bit on a define value.

Thought that was you... You already have !define /math for that. It doesn't have bitwise AND, OR and XOR operators but I've added that for the next version.

Just a precision : for !define with /math option, the value of define is the result of the operation ?

In my case, I'd like to check if some bits are present on a define value to create the section.
For example, if bit 1 and 4 of SECTIONDEF(=9) are set, I will declare my section like this :
Section "!SECTEXT"
SectionIn 1

This is in order to make different packages with only one common file with NSIS code and different headers file to define the behavior of sections (including the common file).

I hope you understand what I mean.

Thank you

Then do:

code:
!define /math result ${somedef} & 0x008

!if ${result} != 0

#...

But I can't define two time "result", and I'd like to check different bit on different case.

I can use different define name, but if I use it in macro, it will create a lot of define.

The code I'd like to do :

code:
!macro CreateSection SecDef SecText SecIdx

!if ${${SecDef}} == 0

  Section "-${SecText}" ${SecIdx}

!else

  !if ${${SecDef}} & 0x0008

    Section "!${SecText}" ${SecIdx}

  !else

    Section "${SecText}" ${SecIdx}

  !endif

  !if ${${SecDef}} & 0x0001

    SectionIn 1

  !endif

  !if ${${SecDef}} & 0x0002

    SectionIn 2

  !endif

  !if ${${SecDef}} & 0x0004

    SectionIn RO

  !endif

!endif

!macroend

Then !undef result right after you use it.

I forgot it.
Thanks
