What about using a wrapper around rdmd, so the program is executed with an
additional parameter or an environment variable containing "FULL_PATH".

When I started with D, I "accidentaly" wrote my own replacement script for rdmd
compiling xyz.d with dmd to xyz or calling xyz depending on the modification times of the files.

For others who may see this thread, the __FULL_FILE_PATH__ special trait was added to the dmd compiler with this PR: https://github.com/dlang/dmd/pull/5959

At the time of this post, the latest released version of D is 2.071.1, so this trait should be available on any release after that.

Except it doesn't?

auto x(string fp = __FULL_FILE_PATH__)()
{
   pragma(msg, fp);
}

__FILE_FULL_PATH__, not __FULL_FILE_PATH__ (yes, it was wrong in the post you quoted).

In addition, you must instantiate the template:

void main()
{
    x();
}
