Au3Check and ERROR: x previously declared as a 'Const'

[water]

I write an UDF (ExcelChart.au3) where I include another UDF (ExcelChartConstants.au3) containing all the constants definitions. Au3Check for my UDF (ExcelChart.au3) runs just fine.

If my UDF is combined with another UDF (Excel.au3) then I get a lot of

ERROR: x previously declared as a 'Const'

messages.

I've set flag "-w- 3" to ignore already defined vars

#Tidy_Parameters= /gd 1  /gds 1 /nsdp
#AutoIt3Wrapper_Au3Check_Parameters= -d -w 1 -w 2 -w- 3 -w 4 -w 5 -w- 6
#AutoIt3Wrapper_Au3Check_Stop_OnWarning=N

but I still get the errors.

Does this flag only work for variables?

I would like to include all constants in my UDF so it can be run independent from Excel.au3 but suppress all error messages if the user decides to include Excel.au3.

Reproducer scripts:

test.au3:

#AutoIt3Wrapper_Au3Check_Parameters= -d -w 1 -w 2 -w- 3 -w 4 -w 5 -w- 6
#include <a.au3>
#include <b.au3>

a.au3:

Global Const $a = 1

b.au3:

Global Const $a = 1

Error messages I get:

I think that's tricky. Your user could add the include files to his script in any order. Ideally, excel.au3 would have an include for ExcelChartConstants.au3 which itself has #include_once. So you could distribute your own version of Excel.au3.

The only way I know to deal with this is (assuming #include b.au3 is after #include a.au3 )

;b.au3
if Eval('a') = '' Then
    assign('a',1,2)
EndIf

An alternative would be to give the constants in your file a prefix so that there would then be no conflict with the names in the standard udf.

The other way round: When do I use flag "-w- 3"?

In your own UDF, would IsDeclared() be useful in this case?

Thanks for your reply.

Unfortunately this doesn't work because the error pops up during compile time and function IsDeclared is evaluated during run time.

I found out that  these 2 UDF does not get along and causing  error

XML.AU3 AND ADO_CONSTANT.AU3   any work around ?

How you came to this conclusion ?
