<< I am looking for Ada equivalents for the C preprocessor macros
"__FILE__" and "__LINE__", which result in the source file name
(constant string) and the line number (integer) of the file/position
they are specified, respectively. As far as I know there are no
pragma's in Ada 95 or GNAT 3.x that do similar things. Maybe there are
other means to do the same ? Or is this impossible in Ada 95 ?>>
There is no predefined way of doing this in Ada 95, and indeed it is highly
implementation dependent by definition (what is a "source file name"?)
It would be easy to implement an attribute (not a pragma, I don't see how
a pragma would work) that would provide this information, e.g.
Standard'Line
Standard'File
(applying attributes to Standard in such a case is an existing trick in
GNAT for defining new attributes)
or you could, perhaps more cleanly, have two intrinsic functions in a
library routine.
However, none of our customers has requested such a feature, so it is not
on our priority radar screen at the moment ....
