I'd like to be able to start enumerate binary flags starting from 0.
Removing one of the commented parts in the code example above shows that this can't be done.

My Workaround:

Code: Select all

Macro BinaryEnumeration
	((#PB_Compiler_EnumerationValue-1)<<1+((#PB_Compiler_EnumerationValue-2)&$8000000+(~-#PB_Compiler_EnumerationValue)&$8000000)>>27)
EndMacro

Enumeration #Null
	#STPF_NONE						=BinaryEnumeration
	#STPF_USEAPPTHUMBNAILALWAYS		=BinaryEnumeration
	#STPF_USEAPPTHUMBNAILWHENACTIVE =BinaryEnumeration
	#STPF_USEAPPPEEKALWAYS			=BinaryEnumeration
	#STPF_USEAPPPEEKWHENACTIVE		=BinaryEnumeration
EndEnumeration

Debug #STPF_NONE
Debug #STPF_USEAPPPEEKWHENACTIVE

Code: Select all

EnumerationBinary
   #STPF_NONE = 0
   #STPF_USEAPPTHUMBNAILALWAYS = 1
   #STPF_USEAPPTHUMBNAILWHENACTIVE
   #STPF_USEAPPPEEKALWAYS
   #STPF_USEAPPPEEKWHENACTIVE
EndEnumeration

Debug #STPF_USEAPPPEEKWHENACTIVE

Nice try, Wilbert

I still prefer a fool proof handling, so the next value after 0 should be 1 - this could save you some time for trouble shooting.
