optional parameter

[Polo]

Hello,

I hope this hasn't been asked before, it seems using the optional parameter won't work with Tailbite

(with Procedure MyProcedure(parameter=2) for instance.

I think in the past we used to have Procedure2 Procedure3 for this, but now it is native with Purebasic could it be too for Tailbite ?

cheers

Sorry, but no. You have to stick with the old fashioned way.
But you could write a procedure with optional paramters and then write some ProcedureDLL/ProcedureDLL2/ProcedureDLL3 ... :

Code: Select all

Procedure MyOptionalParameterTest(A=1,B=2,C=3)
  MessageRequester("MyOptionalParameterTest",Str(A)+Str(B)+Str(C))
EndProcedure

ProcedureDLL MyTest()
  MyOptionalParameterTest()
EndProcedure

ProcedureDLL MyTest2(A)
  MyOptionalParameterTest(A)
EndProcedure

ProcedureDLL MyTest3(A,B)
  MyOptionalParameterTest(A,B)
EndProcedure

ProcedureDLL MyTest4(A,B,C)
  MyOptionalParameterTest(A,B,C)
EndProcedure

Look @ this polo : http://www.purebasic.fr/french/viewtopi ... =optionnel

Would it be hard to implement the feature ?
It's so simple with the optionnal parameter that Purebasic proposes !

Code: Select all

Declare MyTest4(A,B,C)

ProcedureDLL MyTest()
  ProcedureReturn MyTest4(1,2,3)
EndProcedure

ProcedureDLL MyTest2(A)
  ProcedureReturn MyTest4(A,2,3)
EndProcedure

ProcedureDLL MyTest3(A,B)
  ProcedureReturn MyTest4(A,B,3)
EndProcedure

ProcedureDLL MyTest4(A,B,C)
  ; MyTest(A=1, B=2, C=3) < ----
  ; your code
EndProcedure 

This work for me.

This is a workaround but it would be great to have it native

only the syntax is difference, but the way and the result is the same
