[Swig-user] overriding typemaps

[Prepscius, C. \(IT\) <Col...@mo...>]

Hi - I'm using swig 1.3.24 with python.

In wrapping code that returns a char[], some typemaps are used (below),
which are defined in pystrbase.swg.  I'd like to override these typemaps
and use something different.  So I added my own typemaps that look
exactly the same, except for some small changes, in my project.i file
(_before_ the %include "thethingimwrapping.h").  However, my typemaps
seem to have no effect - I don't see the 'small changes' show up in the
generated c code. =20
=20
I'd like to not change the pystrbase.swg file - I'd like to 'override'
what is in there for this project.  Anybody know how to do that?  I
found some file mumbling about "fragments.i", but there is no
documentation at all about how that's supposed to work...
=20
thanks in advance!

  while (size && ($1_name[size - 1] =3D=3D '\0')) --size;
%#endif
  $input =3D SWIG_FromCharArray($1_name, size);
}
