Another point: Each template type must be individually instantiated
in the code. This is not automated in any way except for the SWIG
MAGIC stuff, but some parts of it probably could be automated via
#define's or something like that. All of this means that instead of
defining some code ("XXX") and having the Makefile expand it,
everything is in the code instead .. all of the instantiations,
whether SWIG or C++. This makes it simple to change the code for new/
other template types (copy, paste, replace-string), but it's not as
automated as that which the Makefile provides (via a list of
expansion types). It's a trade-off; somewhere a list has to be put
together to handle what the expand or instantiate.

Can you point us to the code
I'll post the code for demo_sig_source instead once it compiles and
works, most likely later today (for me, now, since I'm up way too late).
, and show for example, how you'd handle
gr_sig_source*?
Since the X instantiations are 's', 'i', 'f', and 'c', and the only
method that's non-standard is "::work", and there is only one
"complex" type that I've ever seen used in GNU Radio ("gr_complex"),
then I'll write the 'default' code for non-complex types since there
are many more of them, and overload it for "gr_complex"
specifically. The rest will be about the same as my current code for
template expansion since all the other methods are common to all
output types. This is the same method used for modifying the base
name of the block (overloading a "make_name" method, one for each
desired template type). - MLD
