No "pragma Deprecated (NAME)"?

No "pragma Deprecated (NAME)"?

[Michael R]

Hi folks,

I was re-organizing some code and wanted to change some procedure/
function names, e.g.,

    function To_String (T : My_Type) return String;

becomes

   function Name (T : My_Type) return String;

Without consulting the docs, I tried

   function Name (T : My_Type) return String;
   function To_String (T : My_Type) return String
      renames Name;
   pragma Deprecated (To_String);

I guess I'm too used to annotating methods in Java and was surprised I
couldn't do this in Ada.

The only way to do this is to simply rename and fix the compilation
errors which is may be in the Ada style: just get it right.

Take care,
Michael.

"Deprecated" is not a language-defined pragma, but unrecognized pragmas should 
be ignored (ARM 2.8). I see nothing wrong with your function renaming. What 
error message did you get?

Hi,

Yes, it generated a warning as un-recognized but I was hoping for the
functionality, i.e., the
implementation of this pragma where usage of the old name generates
deprecated warning when
used.

Take care,
Michael.

GNAT has an implementation-defined "pragma Obsolescent", see
