How to determine if variable is a valid Structure?

[skywalk]

I already use a Map of known structures, but curious if there is another way to pass the variable contents to the Defined compiler function?

Code: Select all

Define.s myVar$ = "RECT"
NewMap mapSTRUCT.i()
mapSTRUCT("RECT") = 1
Debug Defined(RECT, #PB_Structure)
Debug mapSTRUCT(myVar$)               ; 1
Debug Defined(myVar$, #PB_Structure)  ; 0

You can check with Defined

#PB_Constant
#PB_Variable
#PB_Array
#PB_List
#PB_Map
#PB_Structure
#PB_Interface
#PB_Procedure
#PB_Function
#PB_OSFunction
#PB_Label
#PB_Prototype
#PB_Module
#PB_Enumeration

Code: Select all

Define.s myVar$ = "RECT"
NewMap mapSTRUCT.i()
mapSTRUCT("RECT") = 1
Debug Defined(RECT, #PB_Structure)
Debug mapSTRUCT(myVar$)               ; 1
Debug Defined(myVar$, #PB_Structure)  ; 0

Debug Defined(myVar$, #PB_Variable)   ; 1
Debug Defined(mapSTRUCT, #PB_Map)     ; 1

Yes, I know Defined(), but I'm trying to trick it with the contents of my string variable.
Defined("RECT", #PB_Structure) = 0
I am parsing C headers and need to keep valid Struct's when encountered.
Now I must use a pre-filled mapSTRUCT().

I would say no. 'Defined' is a compiler function and so isn't of any use based on changeable data at runtime (such as your string contents).

Constructing a collection of the valid parsed Structures would seem to be the only viable solution.

Thanks Demivec, I was making sure no other way to access the known resident Structures.
